detailed description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

In order to improve the efficiency of image management operations, according to one aspect of the present invention, an image storage method is provided. The image storage method is especially suitable for storing a large number of images. Fig. 1 shows a schematic flowchart of an image storage method 100 according to an embodiment of the present invention. As shown in FIG. 1 , the image storage method 100 includes step S110 , step S120 and step S130 .

In step S110, a globally unique identifier of the image is determined. Wherein, the globally unique identifier of the image is mapped one-to-one to the storage address of the image.

Each image to be stored will be stored to a unique storage address. The storage address may be a disk address, or an address in a database established based on the disk address. A globally unique identifier is unique across the entire storage system. There is a one-to-one mapping relationship between the globally unique identifier and the storage address of the image.

Specifically, step S110 may include: first, randomly generating a 64-bit binary number as a globally unique identifier of the image to be stored. Then, a one-to-one mapping between the globally unique identifier and the storage address of the image to be stored is established. Please note that the above method for constructing the globally unique identifier is for illustrative purposes only, and is not a limitation of the present invention. Those skilled in the art can also use other means to construct a globally unique identifier.

In step S120, a multi-level index of the image is established and stored according to the attachment information of the image to be stored. Through the multi-level index, the entire image storage space is divided into multiple levels, which can significantly improve the efficiency of management operations such as image retrieval, analysis, and display.

The attached information of the image may include the globally unique identifier of the image determined in step S110 above. The globally unique identifier can be used as the key value of the above-mentioned multi-level index. The attached information of the image may also include the user identifier of the image capture device. For an image storage system, it may need to store images of many users. Users can be identified based on the user identifier of their image capture device. For example, a user can manage multiple image acquisition devices with the same application program (APP). Then, the user name of the user logging into the APP may be used as the user identifier of the user's image acquisition device. The accompanying information of the image may also include an image source identifier. Each image exists from its own source, such as a specific image capture device. The image source identifier may be a product serial number of the image capture device. The attached information of the image may also include the image acquisition date.

A multi-level index of an image can be established according to the attached information of the image. Wherein, each upper-level index corresponds to one or more lower-level indexes. The upper-level index and the lower-level index are two relative concepts. Through the upper-level index, you can index to its lower-level index. The images involved in a superior index are exactly the same as the images involved in all its subordinate indexes.

There exists at least one upper-level index corresponding to a plurality of lower-level indexes. Thus, the images corresponding to the upper-level index can be divided into different lower-level indexes. In a specific example, most or even all of the upper-level indexes may correspond to multiple lower-level indexes.

Fig. 2 shows a schematic diagram of a multi-level index according to an embodiment of the present invention. As shown in Figure 2, the multi-level index includes two levels. The top table in Figure 2 represents the first-level index, and the three tables in the middle represent the second-level index. The first level index refers to all images stored. Each second-level index includes a portion of images. The bottom bars represent image storage spaces, such as different server clusters.

In a multi-level index, each upper-level index includes values used to determine adjacent lower-level indexes. The value used to determine the adjacent lower-level index is used to divide the images involved in the upper-level index into corresponding adjacent lower-level indexes. Thus, the entire multilevel index becomes an indivisible whole. In a specific example, each upper-level index may be an index table, and the index table may include multiple columns, wherein the value of a certain column is used to determine adjacent lower-level indexes. That is to say, according to different values in the column, the corresponding images are divided into different adjacent lower-level indexes.

Still taking the multi-level index shown in FIG. 2 as an example, the value in the last column of the first-level index in FIG. 2 is the acquisition date of the image, which is used to determine the adjacent lower-level index. As shown by the different curves in Figure 2, the image whose acquisition date is "20141020" will be divided into the leftmost one in the second-level index shown in Figure 2, and the image whose acquisition date is "20141021" will be divided into the The middle one in the second-level index shown in Fig. 2, the image whose acquisition date is "20141022" will be divided into the rightmost one in the second-level index shown in Fig. 2 .

In a multi-level index, the lowest-level index includes a globally unique identifier for an image. In other words, the globally unique identifier is located at the bottom of the multi-level index, so as to establish a connection between the multi-level index and the storage space of the image.

In the multi-level index shown in FIG. 2 , the globally unique identifier is a key value in the multi-level index, which is expressed by the word "Key". As shown in FIG. 2 , the "Key" column in the second-level index stores the globally unique identifier of the multi-level index, which is in one-to-one correspondence with the storage space of the image.

The following takes the establishment of the secondary index shown in FIG. 2 as an example to illustrate the specific process of establishing a multi-level index. For the image to be stored, first obtain its auxiliary information, which may include the user identifier (Uid) of the image acquisition device, the image source identifier (Sn) and the acquisition date (Date) of the image. Then, the side information of the image is added to the first-level index. When the auxiliary information of the image is the same as that of the existing image in the storage system, in this step, the first-level index is not added repeatedly. As shown in the first-level index in Figure 2, the fourth line in the first-level index can indicate that the image acquisition device with the serial number "daggsd" of the user whose user identification code is "135" collected on October 22, 2014 image, and the image is stored in the storage system. It can be understood that the data in each row of the first-level index cannot indicate the number of corresponding images, but can only indicate that there are images with the auxiliary information in the storage system. For example, the fourth row in the first-level index corresponds to the three rows of data in the rightmost second-level index. Finally, according to the acquisition date of the image, some of the auxiliary information and the globally unique identifier of the image are added to the corresponding second-level index. For example, add the user identifier (Uid), image source identifier (Sn) and globally unique identifier of the image capture device whose capture date is "20141022" to the rightmost second-level index shown in Figure 2 . Because each GUI is unique, each row in the second-level index uniquely corresponds to an image. For example, the first row of the rightmost one in the second-level index indicates that the user identification code is "135" and the image acquisition device with the serial number "daggsd" of the user is stored on October 22, 2014 in the same The storage space corresponding to the globally unique identifier "D". It can be understood that the image acquisition device with the serial number "daggsd" of the user whose user identification code is "135" may have acquired multiple images on October 22, 2014, and these images have different globally unique identifiers, such as The three rows of data in the rightmost second-level index in Figure 2 are shown.

In step S130, the image is stored to the storage address of the image mapped to the globally unique identifier of the image. The object of the storage operation here is the image data itself.

Images can be stored in dot matrix. A dot matrix is an array of dots, and the dots in the array can be called pixels of an image. Images can also be stored mathematically, for example as vectors.

From another perspective, the image can be in various formats, such as JPG format, BMP format, and so on.

The bottom column in Figure 2 represents the image storage space, such as different server clusters. As shown in the curve in the figure, store the images whose "Key" values of the second-level index are "A" and "C" respectively in the corresponding addresses in the first server cluster, and set the "Key" values of the second-level index to The image of "B" is stored to the corresponding address in the second server cluster, and the image whose "Key" value of the second-level index is "D" is stored to the corresponding address in the third server cluster.

The above image storage method 100 shows the specific execution sequence of step S110, step S120 and step S130. However, those skilled in the art can understand that the execution sequence shown is only an example, not a limitation. For example, step S130 may be performed prior to step S120. Optionally, step S130 can be executed simultaneously with step S120, so as to improve the execution speed of the image storage method 100 .

When performing management operations such as retrieval, display, and deletion on the images stored based on the above-mentioned image storage method 100, firstly, the uppermost index can be retrieved, and the lower indexes can be retrieved according to the uppermost index. Similarly, searches are performed level by level until the lowest level index is retrieved. Finally, according to the globally unique identifier of the image in the lowest-level index, the storage address of the image can be retrieved to obtain the image.

The image storage method 100 described above utilizes a multi-level index. At least one upper-level index can index multiple lower-level indexes, thereby solving the problem of low efficiency in image retrieval, display, deletion and other management operations in the prior art, and correspondingly achieving the beneficial effect of improving image management efficiency.

Optionally, establishing the multi-level index of the image in step S120 may further include step S121, establishing a first-level index according to the first group of auxiliary information of the image.

This step S121 may specifically include: first, judging whether the first group of auxiliary information of the image overlaps with the first group of auxiliary information of the image in the first-level index. Then, for the case of no duplication, the first set of side information of the image is added to the first-level index. In this way, repeated rows in the first-level index are avoided, and the accuracy of the first-level index is guaranteed.

Step S120 may also include step S122, establishing a second-level index according to the second group of auxiliary information of the image. In this step, a second set of side information of the image is added to the second-level index. Thus, the established multi-level index is a secondary index. As mentioned above, FIG. 2 shows a schematic diagram of a secondary index according to an embodiment of the present invention.

On the one hand, the amount of storage and calculation brought by the secondary index is small. On the other hand, since the primary index can correspond to many secondary indexes. That is to say, the dimensions of the primary index can be much larger than that of the secondary index. Therefore, through the secondary index, all images can be conveniently managed and the management efficiency can be improved.

Those skilled in the art can understand that more than three levels of indexes can also be established, which can support the storage and management of a larger number of images. But this will bring a greater burden of storage and computing to the storage system.

According to an example of the present invention, the establishment of the first-level index in the above-mentioned step S121 further includes: establishing the first-level index according to the first auxiliary information and the acquisition date of the image. Wherein, the collection date of the image is used to divide the images involved in the first-level index into the second-level index. Thus, the images involved in each second-level index are images acquired on the same day. The establishment of the second-level index in the above step S122 further includes: establishing the second-level index according to the first attachment information and the globally unique identifier of the image.

In the scheme according to this example, the images are divided into different second-level indexes according to different acquisition dates of the images. As the secondary index shown in FIG. 2 , the primary index includes three columns. The last column "Date" is the acquisition date of the image, which is used to determine the second level index of the image as described above.

The acquisition date of an image is an important attribute of an image. In a multi-user image management system, users may request retrieval and display of images on a specific acquisition date. For example, for an APP used to monitor image information of a specific location, it may have millions of users. The APP uses an image acquisition device to collect a large number of images. It may be desirable for a user to look back and retrieve images for a certain period of time. The image is further divided by the date of image collection, which can make image management more convenient.

As the secondary index shown in FIG. 2 , the above-mentioned first auxiliary information may further include a user identifier (Uid) and/or an image source identifier (Sn) of the image acquisition device. These two are also one of the important attributes of images. When a user makes a request for image retrieval and display, it is hoped that the desired result can be quickly returned to the user. The user identifier and image source identifier of the image acquisition device are attributes related to the user, and by using them, the desired image of the user can be located relatively quickly.

Fig. 3 shows a schematic flowchart of an image storage method 300 according to another embodiment of the present invention. As shown in FIG. 3 , the image storage method 300 includes step S310 , step S320 , step S330 and step S340 . Wherein, step S310 , step S320 and step S330 are respectively similar to corresponding steps in the above-mentioned image storage method 100 , and for the sake of brevity, details are not repeated here.

In step S320, a multi-level index of the image is established and stored according to the attached information of the image. Wherein, the attached information of the image includes the collection date of the image. In step S340, delete the first acquired image and the index of the first acquired image according to the acquisition date of the image, so as to release storage space.

The storage space of the storage system is limited. How to make reasonable use of this limited storage space is an important issue. For users, such as the users of the APP used to monitor the image information of a specific location in the above example, recent images are usually more valuable. In this step S340, the first collected image and its index are deleted according to the collection date of the image, and the more important images for the user are retained, which can release storage space while satisfying the user's needs.

It can be understood that in the above image storage methods 100 and 200, the lower-level index of the image may be stored in a server cluster, which is different from the server cluster storing the lower-level indexes of other images. The lower index of the image is multiple. There can also be multiple server clusters. The lower-level indexes of different images can be stored in different server clusters, thereby making more reasonable use of storage space.

For an image to be stored, its storage address may be located in a different server cluster from the storage addresses of other images. Returning to Fig. 2 again, the user identifier Uid of the image acquisition device is "123", the image source identifier Sn is "dddddc" and the image whose key value Key is "A" is stored in the first server cluster, and the image acquisition device's The images whose user identifier Uid is also "123", image source identifier Sn is "adadfs" and key value Key is "B" are stored in the second server cluster. The image storage methods 100 and 200 described above support storing different images in different server clusters, effectively expanding the storage space of images through different server clusters.

According to another aspect of the present invention, an image storage device is also provided. Fig. 4 shows a schematic block diagram of an image storage device 400 according to an embodiment of the present invention. As shown in FIG. 4 , the image storage device 400 includes determining means 410 , indexing means 420 and storage means 430 .

The determining means 410 is used for determining the globally unique identifier of the image, wherein the globally unique identifier is mapped one-to-one to the storage address of the image.

The indexing device 420 is used for establishing and storing a multi-level index of the image according to the auxiliary information of the image. Each upper-level index includes a value for determining an adjacent lower-level index, and the value is used for dividing the images involved in the upper-level index into corresponding adjacent lower-level indexes. The lowest-level index includes a globally unique identifier for the image.

Optionally, the indexing device 420 further includes a first indexing module 421 and a second indexing module 422 . The first index module 421 is configured to establish a first-level index according to the first set of auxiliary information of the image. The second index module 422 is used for establishing a second-level index according to the second group of auxiliary information of the image.

Optionally, the first index module 421 further includes a first index establishment unit, which is configured to establish a first-level index according to the first auxiliary information of the image and the acquisition date, wherein the acquisition date of the image is used to convert the first-level index to The images involved are grouped into a second-level index. The second index module 422 further includes a second index building unit, which is used for building a second-level index according to the first attachment information and the globally unique identifier of the image.

The first auxiliary information may further include: a user identifier and/or an image source identifier of the image acquisition device.

Optionally, the indexing device 420 further includes an index storage module, configured to store the lower-level index of the image in a server cluster, wherein the server cluster is different from the server cluster storing the lower-level indexes of other images.

The storage device 430 is used to store the image to the storage address of the image mapped by the globally unique identifier of the image. Optionally, the storage address of the image is located in a different server cluster from the storage addresses of other images.

Fig. 5 shows a schematic flowchart of an image storage device 500 according to another embodiment of the present invention. As shown in FIG. 5 , the image storage device 500 includes determining means 510 , indexing means 520 , storing means 530 and deleting means 540 . Wherein, the determining means 510, the indexing means 520 and the storing means 530 are respectively similar to the corresponding components in the above-mentioned image storage device 400, and for the sake of brevity, details are omitted here.

The deleting unit 540 in the image storage device 500 is configured to delete the first captured image and the index of the first captured image according to the capture date of the image, so as to release storage space.
