detailed description

The overall inventive idea of the present invention is to detect whether there is a change in the scene, and send out a reminder message when the scene changes. For detecting whether the scene has changed, the present invention provides three solutions: determine whether the scene has changed by detecting whether the image difference between two adjacent frames is greater than a preset threshold; determine whether the scene has changed by detecting whether the camera parameters have changed; simultaneously detect Whether the image difference between two adjacent frames is greater than a preset threshold and whether the camera parameters have changed determines whether the scene has changed.

In order to further explain the technical means adopted by the present invention and the effects obtained, the present invention will be clearly and completely described below in conjunction with the accompanying drawings and preferred embodiments, starting from the above-mentioned three schemes for detecting whether there is a change in the scene.

Embodiment one

From the perspective of detecting camera parameters to determine whether the scene changes, the method for reminding when there is an abnormality in the monitoring space of the present invention is introduced in detail.

As shown in Figure 1, a method for reminding when there is an abnormality in the monitoring space includes steps:

S110. Acquiring current parameter information of an on-state camera in the monitoring space;

S120. Comparing the current parameter information with the parameter information of the imaging device acquired at a previous moment, and detecting whether the two are consistent;

S130. If inconsistent, send a preset reminder message to the associated target contact.

The method of the present invention can be realized according to a corresponding program, and the program can run on a terminal, such as a mobile phone. The method of the present invention can not only ensure the safety of people in the vehicle, but also can ensure the safety of people in other monitoring spaces, such as the safety of people in a room, the safety of babies in cribs, etc., which is not limited by the present invention. In order to better understand the method of the present invention, each step of the present invention will be described in detail below.

In step S110, the monitoring space may be any space that needs to be detected. The camera device may be a camera carried by the mobile terminal, or may be a camera or the like. The parameter information includes AEC (Auto Exposure Control) parameters, AWB (Auto White Balance parameters), AF (Auto Focus parameters) and the like.

In step S120, since the scene change will trigger the resetting of the camera's AEC, AWB, AF and other parameters, it can be determined whether the scene has changed by detecting whether these parameters have changed. It is possible to detect whether there is any change in the parameter information of the camera device that is turned on by monitoring.

In step S130, in one embodiment, if not consistent, the step of sending a preset reminder message to the associated target contact may include:

If at least one of the automatic exposure control parameter, the automatic white balance parameter and the automatic focus parameter is inconsistent, a preset reminder message is sent to the associated target contact.

When judging scene changes, the accuracy of AEC parameter judgment alone is high, and the precision of AWB and AF parameters alone judgment is low, so as a preferred embodiment, the parameters are determined only when a change in AEC parameter is detected There is a change, and a reminder message is sent to the target contact.

The reminder information can be in video format, recording format, text format, etc., and the specific content can be set according to the actual needs of the user. In order to allow the target contact person to understand the situation and take measures in time, the reminder message may contain distress words. The target contact can be defined according to the actual needs of the user. The target contact can include only one contact, or it can be a group containing multiple contacts. The contacts included in the target contact can be relatives or public For emergency calls, such as 110 and 120, etc., when the target contact contains multiple contacts, the user can also set the priority of each contact, and the reminder information will be sent in the order of the set priority.

In one embodiment, the step of sending a preset reminder message to the associated target contact may include:

Take a video image of a preset time length, and send the video image to an associated target contact through instant messaging software;

When the parameters change, that is, when the scene changes, video images of a certain length of time can be collected on site, for example, 5 seconds of video images, and then the collected video images can be sent to the bound target through instant messaging software such as WeChat, QQ or Fetion Contacts, so that the target contacts can view the current scene, so as to take corresponding measures according to the viewed video images. The method of sending the data to the designated contact person through the instant messaging software can be realized according to the existing methods in the prior art.

and / or,

Obtain the geographic location information and the preset license plate number of the monitoring space, and send the geographic location information and the license plate number to the associated target contact via a text message;

Information such as the license plate number can be pre-stored in the terminal and obtained when the reminder message is sent. The geographic location can be obtained according to the positioning system of the mobile terminal. If the positioning system of the mobile terminal is turned off, when a scene change is detected and a reminder message needs to be sent, the positioning system is triggered to be turned on, the current location information is obtained, and then sent to the target contact.

and / or,

When dialing the number of the target contact, it can be dialed sequentially according to the order of priority set in advance. In order to prevent the contact from answering for a long time and causing the rescue opportunity to be missed, the time for making a call can be set. If the contact has not reached the set time Answer, the call will be automatically transferred to the phone number of the next contact. When the call is connected, the recording of the geographic location information and the license plate number is played.

In order to avoid false alarms and further ensure accuracy, in an embodiment, the method of the present invention may further include a step of: acquiring the sound decibel value of the external environment and/or the acceleration value of the acceleration sensor. The sound decibel value can be obtained according to the existing sound detection application. If the sound decibel value is greater than the set decibel value, it may be that the child in the car is crying loudly. If the acceleration value is greater than the set acceleration value, it means that the object is vibrating. Taking a car as an example, it may be that a child in the car is hitting the car body. When the parameter information of the previous two times is inconsistent, and the sound decibel value is greater than the set decibel value and/or the acceleration value is greater than the set acceleration value, a reminder message is sent to the target contact.

Embodiment three

From the perspective of detecting image differences to determine whether the scene has changed, the method for reminding when there is an abnormality in the monitoring space of the present invention is introduced in detail.

As shown in Figure 3, a method for reminding when there is an abnormality in the monitoring space includes steps:

S210. Collect images in the monitoring space, and acquire two adjacent frames of images from the images;

S220. Calculate the difference value between the two frames of images;

S220. When the difference value is greater than a preset threshold, send a preset reminder message to the associated target contact.

The method of the present invention can be realized according to a corresponding program, and the program can run on a terminal, such as a mobile phone. The method of the present invention can not only ensure the safety of people in the vehicle, but also can ensure the safety of people in other monitoring spaces, such as the safety of people in a room, the safety of babies in cribs, etc., which is not limited by the present invention. In order to better understand the method of the present invention, each step of the present invention will be described in detail below.

In step S210, the camera device may be a camera carried by a mobile terminal, or may be a camera or the like. When taking images, try to capture various areas where the user may move, so as to better ensure the safety of the user. Taking the safety of children in the car as an example, when shooting scenes in the car, it is best to place the mobile terminal or camera in a position that can capture any area where children can move around in the car.

In step S220, there are many methods for calculating the difference value between the two frames of images. For example, in one embodiment, the step of calculating the difference value between the two frames of images may include: comparing the two frames The RGB (red, green and blue) value of the corresponding pixel of the image; obtain the first quantity that the RGB value is equal and the second quantity that the RGB value is not equal; obtain the sum of the first quantity and the second quantity, according to the first quantity The ratio of the two quantities to the sum to obtain the difference value.

During specific implementation, it is possible to set a parameter f for recording the same RGB value and a parameter g with different RGB values, and both the parameter f and the parameter g start counting from 0. When the RGB values of the corresponding pixels of the two frames of images are the same, the value of the parameter f is increased by 1, and when the RGB values of the corresponding pixels of the two frames of images are different, the value of the parameter g is increased by 1. Then n is obtained according to the expression difference value n=g/(f+g).

In step S230, the preset threshold can be set according to actual needs. Compare the size of the difference value with the preset threshold. If the difference value is greater than the preset threshold, it means that there are many different RGB values, and the difference between the two frames of images is large, and the reminder message will be sent to the target contact; otherwise, the number of different RGB values is small, and the difference between the two frames of images is large. If it is smaller, return to step S210.

The reminder information can be in video format, recording format, text format, etc., and the specific content can be set according to the actual needs of the user. In order to allow the target contact person to understand the situation and take measures in time, the reminder message may contain distress words. The target contact can be defined according to the actual needs of the user. The target contact can include only one contact, or it can be a group containing multiple contacts. The contacts included in the target contact can be relatives or public For emergency calls, such as 110 and 120, etc., when the target contact contains multiple contacts, the user can also set the priority of each contact, and the reminder information will be sent in the order of the set priority.

In one embodiment, the step of sending a preset reminder message to the associated target contact may include:

Take a video image of a preset time length, and send the video image to an associated target contact through instant messaging software;

When the parameters change, that is, when the scene changes, video images of a certain length of time can be collected on site, for example, 5 seconds of video images, and then the collected video images can be sent to the bound target through instant messaging software such as WeChat, QQ or Fetion Contacts, so that the target contacts can view the current scene, so as to take corresponding measures according to the viewed video images. The method of sending the data to the designated contact person through the instant messaging software can be realized according to the existing methods in the prior art.

and / or,

In order to prevent accidents caused by a certain contact not being able to see the text message in time, when sending a text message, the priority of the contact can be ignored, and it can be sent to all contacts directly. Information such as the license plate number can be pre-stored in the terminal and obtained when the reminder message is sent. The geographic location can be obtained according to the positioning system of the mobile terminal. If the positioning system of the mobile terminal is turned off, when a scene change is detected and a reminder message needs to be sent, the positioning system is triggered to be turned on, the current location information is obtained, and then sent to the target contact.

and / or,

Obtain the geographic location information and the preset license plate number of the monitoring space, dial the phone number of the target contact in turn, and play the geographic location information and the license plate number when it is detected that the call is connected;

In order to prevent the contact from answering for a long time and causing the rescue opportunity to be missed, the time for making a call can be set. If the contact has not reached the set time Answer, the call will be automatically transferred to the phone number of the next contact. When the call is connected, the recording of the geographic location information and the license plate number is played.

In order to avoid false alarms, in one embodiment, the method of the present invention may further include a step of: acquiring the sound decibel value of the external environment and/or the acceleration value of the acceleration sensor. The sound decibel value can be obtained according to the existing sound detection application. If the sound decibel value is greater than the set decibel value, it may be that the child in the car is crying loudly. If the acceleration value is greater than the set acceleration value, it means that the object is vibrating. Taking a car as an example, it may be that a child in the car is hitting the car body. When the difference value is greater than a preset threshold, and the sound decibel value is greater than a set decibel value and/or the acceleration value is greater than a set acceleration value, a reminder message is sent to a preset target contact.

In order to avoid false alarms, in one embodiment, the device of the present invention may also include a sound decibel value acquisition module and/or an acceleration value acquisition module, the sound decibel value acquisition module is used to obtain the sound decibel value of the external environment, the acceleration The value acquisition module is used to acquire the acceleration value of the acceleration sensor. The sound decibel value can be obtained according to the existing sound detection application. If the sound decibel value is greater than the set decibel value, it may be that the child in the car is crying loudly. If the acceleration value is greater than the set acceleration value, it means that the object is vibrating. Taking a car as an example, it may be that a child in the car is hitting the car body. The reminder information sending module 330 sends a reminder message when the difference value is greater than a preset threshold and the parameter information has changed, and the sound decibel value is greater than the set decibel value and/or the acceleration value is greater than the set acceleration value. Send to preset target contacts.
