Video storage method, video search method, video storage device and video search device

Technical Field

The present application relates to the field of video processing technologies, and in particular, to a method and an apparatus for video storage and video search.

Background

At present, more and more automobiles are provided with vehicle-mounted NVR (Network Video Recorder). The vehicle-mounted NVR can directly store the video collected by the camera of the automobile in the hard disk plugged in the vehicle-mounted NVR. However, in an actual use process, the hard disks may be inserted in different vehicle-mounted NVRs in a mixed manner, that is, the same hard disk is inserted in different vehicle-mounted NVRs successively. Therefore, videos collected by the cameras of different automobiles are stored in the same hard disk.

Because the vehicle-mounted NVR directly stores the videos collected by the cameras of the automobiles in the inserted hard disks, once one hard disk has the mixed insertion condition, the videos collected by the cameras of different automobiles can be mixed in the hard disk. In this case, when the user wants to view a video captured by the camera of a certain vehicle, the vehicle-mounted NVR may not easily search for the video captured by the camera of the vehicle that the user wants to view from the mixed video.

Therefore, the vehicle-mounted NVR directly stores the video collected by the camera of the automobile in the hard disk, which causes difficulty in searching the video in a targeted manner.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the prior art, videos collected by a camera of an automobile are directly stored in a hard disk by the vehicle-mounted NVR, and the hard disk may be inserted in a plurality of vehicle-mounted NVRs in a mixed manner, so that when videos are searched in the hard disk, video searching is difficult to be conducted in a targeted manner. In order to solve the technical problem, embodiments of the present application provide a video storage method and a video search method and apparatus.

In one embodiment of the present application, a video storage method is provided, which includes:

Because the storage medium stores the video files and also stores the relationship data corresponding to the video files, and the relationship data corresponding to each video file represents the corresponding relationship between the video file and the device for acquiring the video in the video file, when the scheme provided by the embodiment is applied to searching the video, the video files storing the videos acquired by each video acquisition device can be searched according to the relationship data stored in the storage medium, so that the convenience of video searching is improved.

The following respectively describes in detail the video storage and video search methods provided by the embodiments of the present application through specific embodiments.

Fig. 1 is a schematic flowchart of a video storage method according to an embodiment of the present application.

The following first describes an execution body of the video storage method provided in the embodiment of the present application.

In one case, the execution main body may be an electronic device such as a vehicle-mounted NVR, a desktop computer, and a notebook computer. The electronic equipment can obtain the video collected by the video collecting equipment in a mode of being in communication connection with the video collecting equipment, and the electronic equipment can also obtain the video collected by the video collecting equipment in a mode of being in communication connection with other equipment connected with the video collecting equipment. In addition, the electronic device may be connected to the storage medium by plugging or the like.

In another case, the executing body may be a video capture device itself. The video acquisition equipment can acquire videos and can be connected with a storage medium in a plugging mode and the like.

For example, the video capture device may be a CAMERA, an analog CAMERA, an IPC (IP CAMERA), or the like.

The storage medium refers to a carrier for storing data, and may be, for example, a hard disk, a flash memory, or the like.

In still another case, the execution body may be a storage medium itself having a data processing capability. For example, SSD (Solid State Disk), etc.

Specifically, the video storage method includes:

s101: and acquiring equipment information of the video acquisition equipment as first equipment information, and acquiring the video acquired by the video acquisition equipment.

In the case that the execution subject of the embodiment of the present application is not the video capture device itself, the execution subject may obtain device information of one or more video capture devices. For example, when the execution subject is a vehicle-mounted NVR, the video capture device may be each camera on the vehicle for capturing scene information around the vehicle body, and in this case, the vehicle-mounted NVR may obtain device information captured by each camera.

Based on the above, this step may be to obtain device information of one or more video capture devices.

In an embodiment of the application, the device information may include: a device serial number and/or a device identification, etc. In addition, the device information may further include information of a device in which the video capture device is located.

Taking the electronic device as a vehicle-mounted NVR as an example, the device information of the camera in communication connection with the vehicle-mounted NVR on the vehicle may include information such as a serial number of the camera, an identifier of the camera, and the like, and may also include information of the vehicle and the like. For example, the information of the vehicle may be a license plate number, a vehicle number, and the like.

In view of the foregoing, in an embodiment of the present application, device information of a video capture device in communication connection may be specifically obtained as the first device information. For example, in the case where the execution subject is the vehicle-mounted NVR, the vehicle-mounted NVR is communicatively connected to each camera mounted on the vehicle, and at this time, the vehicle-mounted NVR can obtain the device information of one or more cameras communicatively connected thereto.

Due to the reasons of large data volume of videos, limited storage resources of electronic equipment and the like, in order to ensure that videos collected by the video collecting equipment can be completely stored, the electronic equipment can be connected with various storage media in a plugging mode and the like. Based on this, in an embodiment of the present application, when the execution main body obtains the device information of the video capture device, after the execution main body monitors that the storage medium is successfully connected, the video capture device for capturing a video may be determined, and the device information of the determined video capture device may be obtained. That is, the acquisition of the device information is triggered by a connection event on the storage medium and the electronic device. Thus, the obtained device information can be effectively ensured to be: information of a device that collects the video to be stored in the above-mentioned storage medium. In addition, the device information can be effectively prevented from being repeatedly obtained after the storage medium is connected to the electronic device and in the process of storing the video.

Specifically, when the execution subject is the storage medium itself, it can be understood that the following description indicates that the storage medium is successfully connected: the storage medium monitors that it is successfully connected to another electronic device.

When the execution main body is an electronic device other than a storage medium such as a vehicle-mounted NVR and a video capture device, it can be understood that the storage medium is successfully connected when monitoring that the storage medium is successfully connected: the electronic device monitors that the storage medium is successfully connected.

In addition, when obtaining the device information of the determined video capture device, the executing entity may be implemented in one of the following ways:

the first method comprises the following steps: the execution subject may read the device information directly from the determined video capture device.

And the second method comprises the following steps: the execution main body may send an apparatus information acquisition request to the determined video capture apparatus, and after receiving the request, the determined video capture apparatus feeds back apparatus information of the video capture apparatus to the execution main body, so that the execution main body obtains the apparatus information of the determined video capture apparatus.

And the third is that: the execution main body can locally pre-record the equipment information of each video acquisition equipment, and after the video acquisition equipment is determined, the execution main body directly obtains the equipment information of the determined video acquisition equipment from the local.

In another embodiment of the application, the execution main body may further monitor whether a video capture device is successfully connected with the execution main body, and if so, may obtain device information of the video capture device. In this case, the execution body does not consider whether the storage medium is connected, but obtains the device information of the video capture device when the video capture device successfully establishes a communication connection with the execution body.

Since the video capture device continuously captures the video, in an embodiment of the present application, obtaining the video captured by the video capture device may also be understood as: the video collected by the video collecting device is continuously obtained along with the video collected by the video collecting device.

S102: the obtained video is stored in a storage medium in the form of a video file.

Since the execution main body can be connected with the storage medium in a manner of plugging, in one embodiment of the present application, the obtained video can be stored in the form of a video file in the plugged storage medium.

In addition, the execution subject may continuously obtain the video collected by the video collecting device, and in order to prevent the video file from being too large, in an embodiment of the present application, the obtained video may be stored in the storage medium according to at least one of the following manners:

generating a video file for each video with a preset time duration, for example, the preset time duration may be 5 minutes, 10 minutes, and the like;

a video file is generated when the file size reaches a preset size, which may be 100M, 200M, etc., for example.

In addition, after the storage medium is successfully connected, the connection may be disconnected for various reasons, in this case, to prevent the video captured by the video capture device from being lost, when it is detected that the storage medium is disconnected, videos that are not stored in the storage medium in the obtained videos are formed into a video file and stored in the storage medium. That is, the event that the storage medium is disconnected triggers the video file to be formed and stored into the storage medium. For example, the storage medium being disconnected may be the storage medium being pulled from the electronic device.

S103: and storing the corresponding relation data of the stored video file in the storage medium according to the first device information.

Wherein, the corresponding relation data of each video file is used for expressing: the video file and the device for collecting the video in the video file.

For example, the relationship data corresponding to each video file may be: and the name video _ name of the video file and the device information device _ information of the device for acquiring the video in the video file form a corresponding relation.

That is, video _ name ← → device _ information.

The relationship data corresponding to each video file may include at least one of the following information in addition to the name and the device information of the video file:

the video acquisition time period in the video file, the size of the video file, the storage position of the video file, the duration of the video in the video file and the like.

On the basis, in an embodiment of the present application, when the storage medium stores the relationship data corresponding to the stored video file according to the first device information, the video capture time period corresponding to the stored video file may be obtained, and the relationship data corresponding to the stored video file and including the name of the stored video file and the video capture time period may be stored in the storage medium according to the first device information.

The video acquisition time period corresponding to the video file refers to the video acquisition time period in the video file. Specifically, the start time of the video capture time period may be a start time of writing the video in the video file into the storage medium, and the end time of the video capture time period may be an end time of writing the video in the video file into the storage medium, that is, the video capture time period is determined by the storage side time. In addition, the start time and the end time of the video capture time period may also be the start time and the end time of capturing the video in the video file, which are fed back by the video capture device, that is, the video capture time period is determined by the capture-side time.

Next, the storage of the relationship data corresponding to the stored video file in the storage medium will be described from the perspective of the storage method.

In the first case, a specific area may be set in the storage medium for storing relationship data corresponding to the video file stored in the storage medium. In this case, the relationship data corresponding to the video file stored in the storage medium may be directly stored in the specific area.

In the second case, a file for storing the relationship data may also be created in the storage medium, and for convenience of description, the file is referred to as a data file in the embodiment of the present application. In this case, the relationship data corresponding to the video file stored in the storage medium may be stored in the data file.

In a third case, on the basis of the second case, a plurality of data files may be created in the storage medium, each data file being used to store relationship data corresponding to video files belonging to the same video class, and in this case, a data file used to store relationship data corresponding to the stored video file may be determined first, and then the relationship data corresponding to the stored video file may be stored in the determined data file. Therefore, the classified storage of the relational data can be realized, and the searching and the management of the relational data are convenient.

Specifically, the video class to which the video file belongs may be determined according to a device that acquires a video in the video file, for example, the video files that store videos acquired by the same video acquisition device belong to the same video class, and in the case that the execution subject is a vehicle-mounted NVR, the video files that store videos acquired by cameras of the same vehicle may also be considered to belong to the same video class. In addition, the video class to which the video file belongs may also be determined according to a video capture time period corresponding to the video file, for example, video files whose video capture time periods are within the same time period belong to the same video class.

When each data file is used for storing the relationship data corresponding to the video files belonging to the same video class, since the relationship data corresponding to the video files belonging to the same video class may have the same information, in order to reduce the data amount of the data to be stored, the same information in each relationship data may be stored only once when the data is stored in the data file, and then different information in each relationship data is stored respectively.

Taking the case that video files storing videos captured by the same video capture device belong to the same video class, in this case, the device information in each piece of relationship data stored in the data file is the same, so the device information of the video capture device may be stored in the header information of the data file, and then when the relationship data is stored in the data file, only information other than the device information in the relationship data is stored in the data file.

In view of the foregoing, in one embodiment of the present application, when the relationship data corresponding to the stored video file is stored in the storage medium, a video class to which the stored video file belongs may be determined, as the first video class, an end storage location of the stored data in the first storage area is obtained, and the relationship data corresponding to the stored video file is stored to the obtained end storage location according to the first device information.

Wherein the first storage area is: and an area in the storage medium for storing relationship data corresponding to a video file belonging to the first video class.

Therefore, when the relational data are stored, the first storage area can be directly found, and data storage is carried out at the tail storage position of the first storage area without traversing and searching the storage position of the relational data in the storage medium, so that the data storage efficiency can be effectively improved.

Each video class may have class information for a clearer description of each video class. The class information of each video class may include information describing video files in the video class.

For example, in the case that the video class to which the video file belongs is determined according to the device that collects the video in the video file, the class information of the video class may include: the device information of the video acquisition device, the class time period described by the earliest acquisition time and the latest acquisition time of the video in each video file of the video class, the number of the video files in the video class, the tail storage position of the stored data in the storage area, and the like. Wherein, the storage area is: and the storage medium is used for storing the area of the corresponding relation data of the video files belonging to the video class.

Under the condition that the video class to which the video file belongs is determined according to the video acquisition time period corresponding to the video file, the class information of the video class may include: the video acquisition time period corresponding to the video class, the class time period described by the earliest acquisition time and the latest acquisition time of the video in each video file of the video class, the number of the video files in the video class, the tail storage position of the stored data in the storage area, the equipment information of the equipment for acquiring the video in each video file, and the like.

In view of the above, each time the relationship data is stored in the first storage area, the last storage location of the first storage area may be updated into the class information of the first video class, so that when the last storage location of the stored data in the first storage area is obtained, the last storage location of the first storage area may be directly obtained from the class information of the first video class.

In an embodiment of the present application, when the end storage location of the stored data in the first storage area is obtained, the end storage location recorded in the first type of information may be obtained as the end storage location of the stored data in the first storage area. Wherein, the first type information is: class information of the first video class stored in the storage medium.

On the basis, after the relation data corresponding to the stored video file is stored to the obtained tail storage position according to the first device information, video information including the tail storage position of the video in the stored video file can be obtained, and the first type information is updated based on the obtained video information. This makes it possible to update the last storage location recorded in the first type of information to the last storage location of the stored video file.

Specifically, in addition to the end storage location of the stored video file, the video information may further include: a video capture time period, first device information, etc. In this way, the class time period may be updated based on the video capture time period included in the video information, the device information included in the first class information may be updated based on the first device information, and the like.

In addition, when the relationship data is stored in the file in the first storage area, the end storage position of the stored data in the first storage area can also be obtained by obtaining the file end.

As can be seen from the above, when the solutions provided by the above embodiments are applied to video storage, in addition to storing videos collected by the video collecting device in the storage medium, relationship data corresponding to video files are also stored in the storage medium. Because the relationship data corresponding to each video file represents the corresponding relationship between the video file and the device for acquiring the video in the video file, when the video acquired by the video acquisition device is required to be searched after the video acquired by the video acquisition device is stored in the storage medium according to the above manner, the video file in which the video acquired by each video acquisition device is stored can be searched according to the relationship data stored in the storage medium. Therefore, after the video is stored by applying the scheme provided by each embodiment, the subsequent targeted video search is facilitated, and the convenience of the video search can be improved.

Based on the idea of storing relationship data in addition to the video file when storing the video, the embodiment of the application further provides a video searching method.

Fig. 2 is a schematic flowchart of a video search method according to an embodiment of the present application.

The execution main body of the video search method can be electronic equipment such as a vehicle-mounted NVR, a video acquisition device, a desktop computer, a notebook computer and the like, which can be connected with a storage medium in a plug-in mode and the like, and can also be a storage medium with data processing capacity.

Specifically, the video search method includes:

s201: and acquiring the equipment information of the target video acquisition equipment as target equipment information.

In the embodiment of the present application, the target video capturing device is a device for capturing a video to be searched.

In one case, when performing video search, the execution main body in the embodiment of the present application may first obtain a search condition, and then determine a target video capture device by analyzing the search condition, so as to obtain target device information.

In another case, the execution subject of the embodiment of the present application may further obtain device information input by the user as the target device information.

In another case, the execution main body in the embodiment of the present application may further obtain information of a device where the video capture device is located, and then obtain the target device information according to the video capture device set on the device that is known in advance. For example, the vehicle information may be obtained first, and then the device information of the camera mounted on the vehicle, which is known in advance and is characterized by the vehicle information, may be obtained as the target device information.

The present application is described only by way of example, and is not limited to the manner in which the target device information is obtained.

S202: and searching the target video file stored in the storage medium according to the relation data and the target device information stored in the storage medium.

Wherein, the target video file is: storing files of videos acquired by the target video acquisition device, wherein each relationship data corresponds to each video file stored in the storage medium, and the relationship data corresponding to each video file is used for representing: the video file and the device for collecting the video in the video file. That is, each relationship data is used to represent: the corresponding relation between a video file stored in the storage medium and the equipment for acquiring the video in the video file.

Because the relation data corresponding to each video file represents the corresponding relation between the video file and the equipment for acquiring the video in the video file, the relation data related to the target video acquisition equipment can be selected from the relation data stored in the storage medium according to the target equipment information, and the video in the video file related in the selected relation data is acquired by the target video acquisition equipment, so that the search result can be obtained according to the video file related in the selected relation data.

When the storage medium stores the relationship data, the relationship data may be stored in a specific area of the storage medium or may be stored in a file specific to the storage medium.

In searching for a video, a user may want a more accurate video, for example, a video captured by a certain video capture device for a certain period of time, in addition to the video captured by a certain video capture device. In view of this, in an embodiment of the present application, the video search method may further include:

and acquiring a target video acquisition time period.

In this case, when searching for a target video file stored in the storage medium based on the relationship data and the target device information stored in the storage medium, the target video file stored in the storage medium and having a video capture time within the target video capture period may be searched for based on the relationship data and the target device information stored in the storage medium.

Specifically, the target video capturing time period may be obtained by analyzing the search condition, or may be obtained by obtaining time period information input by the user.

As can be known from the foregoing embodiment shown in fig. 1, the relationship data corresponding to each video file may include, in addition to the name and the device information of the video file, information such as a video acquisition time period in the video file, a video file size, a video file storage location, and a video duration in the video file, in this case, relationship data that includes the target device information and includes the video acquisition time period within the target video acquisition time period may be searched in the relationship data stored in the storage medium, and then the video file corresponding to the name of the file in the searched relationship data may be determined as the target video file stored in the storage medium and having the video acquisition time within the target video acquisition time period.

In an embodiment of the present application, the step S201 obtains device information of the target video capture device, and the target device information may be implemented by the following steps a to C.

Step A: a search condition is obtained.

Specifically, the search condition may include information related to a device that collects the video to be searched, and information about a collection time period of the video to be searched.

The information related to the video capture device for capturing the video to be searched may be device information of the video capture device, and may also be information of a device in which the video capture device is installed.

And B: and determining video acquisition equipment for acquiring videos stored in the video files meeting the search conditions as target video acquisition equipment.

C, performing a step; and acquiring the equipment information of the target video acquisition equipment as target equipment information.

When the search condition includes the device information, the device information included in the search condition may be the target device information, and the video capture device indicated by the device information included in the search condition is the target video capture device.

When the carrier information is included in the search condition, the video capture device included in the device may be determined as a target video capture device according to the carrier information, and then device information of the target video capture device, that is, target device information, may be obtained.

When the device including the video capture device is a vehicle, the carrier information may be information of the vehicle, in which case, cameras on the vehicle may be determined according to the information of the vehicle, the cameras are the target video capture device, and the device information of the cameras is the target device information.

On the basis of the above, in the present embodiment, when the above step S202 searches for the target video file stored in the storage medium based on the relationship data and the target device information stored in the storage medium, it can be implemented by the following steps D-F.

Step D: and determining the video class matched with the search condition as the target video class.

Since the above-mentioned video classes may be determined from different angles, the information considered in determining the video class matching the search condition is not the same.

In one case, in the case where the video class is determined according to the video capture device, each video class corresponds to one video capture device, and therefore, when a video class matching the search condition is determined, a video class corresponding to the corresponding video capture device and the video capture device indicated by the search condition may be determined as the target video class.

For example, if the search condition indicates that a video file containing a video captured by device a is searched, video class 1 corresponds to device a, video class 2 corresponds to device B, and video class 3 corresponds to device C, then the target video class is video class 1.

In another case, in the case where the video class is determined according to the video capture period, each video class corresponds to a video capture period, and therefore, when a video class matching the search condition is determined, a video class whose corresponding video capture period coincides with the video capture period indicated by the search condition may be determined as the target video class.

For example, the search condition indicates that a video file containing the captured video at 2019.2.1300: 00:00-23:59:59 is searched, and the video capture time period corresponding to video class 1 is: 2019.1.1300: 00:00-23:59:59, the video collection time period corresponding to the video class 2 is: 2019.2.1312: 00:00-23:59:59, the video acquisition time period corresponding to video class 3 is: 2019.1.1300: 00:00-11:59:59, the target video class is video class 2 and video class 3.

Step E: and determining an area of the storage medium for storing the first relation data as a first storage area.

Wherein the first relation data is: and the relation data corresponds to the video files belonging to the target video class.

When the relationship data is stored in the file of the storage medium, the area where the file for storing the first relationship data is located is the first storage area.

Step F: and searching the target video file which is stored in the storage medium and meets the searching condition according to the relation data and the target device information stored in the first storage area.

Each video class may have class information for a clearer description of each video class. In this case, the number of the relationship data stored in the first storage area may be obtained from the target class information stored in the storage medium, and then the target video file satisfying the search condition among the video files corresponding to the relationship data stored in the first storage area may be searched according to the number and the target device information.

Wherein, the target class information is: class information of the target video class.

As can be seen from the above, in the scheme provided by this embodiment, after the target video class is determined, video file search is performed based on the target video class, so that search in all video files stored in the storage medium can be effectively avoided, and thus search efficiency is improved.

After the electronic device serving as the execution subject of the embodiment shown in fig. 2 obtains the search result, the search result may be sent to the client over the network, so that the user views the search result through the client.

In addition, the electronic device can also directly display the search result, so that the user can view the search result on the electronic device side.

The search result may include the name of the searched video file, a video capture time period, device information for capturing a video in the video file, and the like.

Specifically, in the case that the electronic device sends the search result to the client via the network, the search result may be encapsulated according to a preset network protocol, and then the encapsulated data may be sent to the client.

In the case where the electronic device directly presents the search result, the search result may be represented in a linked list. For example, first, a primary linked list is generated by using the target video class, each target video class is used as a node in the primary linked list, then, a secondary linked list of each target video class is generated by using the target video files meeting the search condition in each target video class, and the corresponding relation data of each target video file is used as a node of the secondary linked list.
