The embodiment of the application takes the method as an example of interactive realization through a camera and a display terminal, and explains the specific processing process of the display method of the monitoring video, wherein the camera can be preset in a target place, the camera can be connected with the display terminal, and an audio acquisition device can be preset in the target place and can be an audio acquisition component contained in the camera. The camera can acquire video data of the surveillance video of the target place and acquire audio data of the surveillance video of the target place through the audio acquisition equipment. The camera may then send the video data and the audio data to a display terminal connected thereto, whereby a user of the video surveillance system may view the surveillance video through the display terminal. The camera may be any electronic Device with a video capture function, such as a web camera or a CCD (Charge Coupled Device) camera. The audio acquisition device may be a microphone; the display terminal is a mobile phone or a tablet computer.
As shown in fig. 1, a specific process of a surveillance video display method may include the following steps:
The preset event may be an event that needs to be displayed and is preset by a user, and the preset event may be, for example, a chat, a kitchen fire, a person calling for help, or the like.
In implementation, the camera may capture a target location to obtain a surveillance video, and then the camera may detect whether a preset event occurs in the surveillance video.
Optionally, the camera may acquire multimedia data of the surveillance video of the target site, where the multimedia data includes video data and/or audio data. Then, the camera may detect whether a preset event occurs in the surveillance video based on the multimedia data, and the detailed processing procedure will be described later.
The manner of acquiring the multimedia data of the surveillance video of the target site by the camera may be: the camera shoots a target place to obtain video data of a monitoring video of the target place. Similarly, the camera may collect the sound in the target location through the audio collecting device to obtain the audio data of the surveillance video in the target location.
And 102, recognizing the occurring preset event, and displaying corresponding dynamic visual information in a display interface of the monitoring video according to the recognition result of the preset event.
The dynamic visual information is used for describing the recognition result of the preset event.
In implementation, if a preset event occurs in the monitoring video, the camera may identify event content of the preset event based on the multimedia data, and determine an event type, an event occurrence time, an event occurrence location, and other identification results of the preset event. If no preset event occurs in the monitoring video, the camera does not need to perform subsequent processing.
In one implementation, the camera may perform data identification on the multimedia data to obtain event content of the preset event, and then determine an event type of the preset event according to a correspondence between the event content and the event type, which are stored in advance. Meanwhile, the camera may determine an event occurrence time of the preset event according to a time stamp of the multimedia data including the preset event. The camera may take the target location as the event occurrence location. Therefore, the camera can obtain the recognition result of the preset event.
And then, the camera can send the recognition result of the preset event to the display terminal, so that the display terminal displays corresponding dynamic visual information in a display interface of the monitoring video according to the recognition result of the preset event, and the detailed description will be given later on in the specific processing process.
In the case of the method for monitoring the video display by the camera, the server and the display terminal together, the camera can acquire multimedia data of the monitoring video of the target place and send the multimedia data to the server, then the server can detect whether the monitoring video has a preset event, if the preset event occurs in the monitoring video, the server can identify the occurring preset event to obtain an identification result of the preset event, and then the identification result of the preset event is sent to the display terminal. And then, the display terminal can display corresponding dynamic visual information in a display interface of the monitoring video according to the recognition result of the preset event.
In the embodiment of the application, the camera can detect whether the monitoring video has a preset event or not, identify the occurred preset event, and then display corresponding dynamic visual information in a display interface of the monitoring video according to the identification result of the preset event. Since dynamic visual information for describing the recognition result of the preset event is displayed, the attention of the user is more easily drawn, thereby prompting the preset event occurring in the target place of the user, and thus, the diversity and interest of video display contents can be realized.
Meanwhile, the user can watch the dynamic visual information used for representing the recognition result of the preset event while watching the monitoring video, so that the user can conveniently understand the content of the monitoring video, quickly know the event occurring in the target place and improve the user experience.
Optionally, for different forms of multimedia data, the camera may detect whether a preset event occurs in the monitoring video based on the multimedia data in different ways. In a possible implementation manner, when the multimedia data includes audio data, the processing procedure of the camera detecting whether the preset event occurs in the surveillance video is as follows: and detecting whether the audio data contains voice information corresponding to the preset event.
In implementation, an audio recognition algorithm may be preset in the camera, and the camera may detect the voice information included in the audio data through the audio recognition algorithm and the audio data, and then determine whether the voice information included in the audio data includes the voice information corresponding to the preset event.
If the voice information corresponding to the preset event exists in the voice information contained in the audio data, the camera can determine that the preset event occurs in the monitoring video; if the voice information contained in the audio data does not have the voice information corresponding to the preset event, the camera may determine that the preset event does not occur in the monitoring video.
For example, the camera can detect the voice information contained in the audio data through an audio recognition algorithm and the audio data to obtain the voice information of 'help me' and the voice information of a dog call sent by a woman. Then, the camera can determine that voice information corresponding to the call for help of the preset event exists in the voice information contained in the audio data, and the camera can determine that the preset event occurs in the monitoring video.
In the prior art, any algorithm with an audio recognition function may be used as an audio recognition algorithm, and the embodiment of the present application is not particularly limited.
In the embodiment of the application, the camera detects whether the voice information contained in the audio data contains the voice information corresponding to the preset event or not through the audio recognition algorithm and the audio data, and can quickly and accurately judge whether the preset event occurs in the target place or not. Therefore, the camera can conveniently and subsequently determine the recognition result of the preset event, the display terminal can conveniently and subsequently display dynamic visual information in the display interface of the monitoring video according to the recognition result of the preset event, and the diversity and interestingness of video display content are realized.
In another possible implementation manner, when the multimedia data includes video data, the processing procedure of the camera detecting whether the preset event occurs in the monitoring video is as follows: whether a video frame of the video data contains image information corresponding to a preset event or not is detected.
In an implementation, an image recognition algorithm may be preset in the camera, and the camera may detect, by using the image recognition algorithm, whether image information corresponding to a preset event exists in image information included in a video frame with respect to the video frame included in the video data.
If the image information contained in the video frame has image information corresponding to the preset event, the camera can determine that the preset event occurs in the monitoring video; if the image information contained in the video frame does not have the image information corresponding to the preset event, the camera can determine that the preset event does not occur in the monitoring video.
For example, the camera may detect, by using an image recognition algorithm, that image information of moving flames exists in image information included in a video frame, with respect to the video frame included in the video data, and then the camera may determine that a preset event occurs in the monitoring video, where event content of the preset event is a fire.
In the embodiment of the application, a mobile detection function can be preset in the camera, and the camera can identify a mobile target in a target place through the mobile detection function and detect whether a preset event occurs in a monitoring video.
In the embodiment of the application, the camera detects whether the image information corresponding to the preset event exists in the image information contained in the video frame through an image recognition algorithm and the video frame of the video data, so that whether the preset event occurs in the target place can be quickly and accurately judged. Therefore, the camera can conveniently and subsequently determine the recognition result of the preset event, the display terminal can conveniently and subsequently display dynamic visual information in the display interface of the monitoring video according to the recognition result of the preset event, and the diversity and interestingness of video display content are realized.
For the case of the method for monitoring the video display by the camera, the server and the display terminal, the server may detect whether the audio data contains the voice information corresponding to the preset event, or detect whether the video frame of the video data contains the image information corresponding to the preset event.
Optionally, the display terminal displays the corresponding dynamic visual information in the preset display page in various ways according to the recognition result of the preset event, and in a feasible implementation manner, the display terminal may display the dynamic visual information according to different display times, and for the implementation manner, the embodiment of the present application provides three examples, specifically as follows:
example one, dynamic visual information is displayed while a preset event is displayed. The specific treatment process comprises the following steps: after receiving the recognition result of the preset event, the display terminal may use the event occurrence time of the preset event as the display time of the dynamic visual information. Then, the display terminal may display the dynamic visual information in the video frame corresponding to the display time in the process of displaying the monitoring video based on the preset display page.
For example, the recognition result of the preset event received by the display terminal includes: the event content is 'help me', the event type is help seeking, the event occurrence time is 9 am, and the event occurrence place is a living room. Then, the display terminal can take 9 am as the display time, take the event content "help me", the event type help and the event occurrence place as the living room as the popup information, and display the dynamic visual information "ask for help-help me-living room" in the form of the popup information in the video frame corresponding to 9 am in the process of displaying the monitoring video based on the preset display page. Fig. 2a is a schematic diagram of a preset display page according to an embodiment of the present disclosure.
In example two, the display terminal may determine a plurality of display times according to an event occurrence time of a preset event and a preset time interval, then determine a video frame corresponding to each display time to obtain a plurality of video frames, and then the display terminal may display dynamic visual information in the plurality of video frames.
And thirdly, the display terminal can determine the display time period of the dynamic visual information according to the event occurrence time of the preset event and the preset display duration, and then the display terminal can display the dynamic visual information in the video frame corresponding to the display time period.
In another possible implementation manner, the display terminal may display the dynamic visual information according to different display positions, for example, the display terminal may display the dynamic visual information in a monitoring video display area of a preset display page, and the display effect is as shown in fig. 2 a. Or, an information display area may be preset in the preset display page, and the display terminal may display dynamic visual information corresponding to the recognition result of the plurality of preset events included in the monitoring video in the information display area. When the amount of the dynamic visual information is too much and the dynamic visual information cannot be displayed in the information display area at the same time, the display terminal can display the dynamic visual information in the information display area in a circulating mode.
As shown in fig. 2b, a schematic diagram of another preset display page provided in this embodiment is shown, where 210 is an information display area, a camera identifies a preset event occurring in a monitoring video to obtain 10 pieces of dynamic visual information, the information display area may simultaneously display 5 pieces of dynamic visual information, and a display terminal may cyclically display 10 pieces of dynamic visual information according to a preset time interval.
In the embodiment of the application, the display terminal may further determine the form of the dynamic visual information according to different event types, for example, if the event type is a help-seeking event, the display terminal may simultaneously display an animation representing the help-seeking event and a text representing the help-seeking event.
In the embodiment of the application, the display terminal can display the corresponding dynamic visual information in the preset display page in various modes, so that the attention of a user can be attracted more easily, and a preset event occurring in a target place of the user is prompted, so that the diversity and the interestingness of video display contents can be realized.
Optionally, in order to facilitate distinguishing between the dynamic visual information of the preset event currently occurring in the monitoring video and the dynamic visual information of the preset event already occurring in the monitoring video, the dynamic visual information of the preset event already occurring is referred to as historical dynamic visual information. When the server displays the historical dynamic visual information of a plurality of preset events at the same time, the server may also provide a playback function of the monitoring video based on the historical dynamic visual information, as shown in fig. 3, the specific processing procedure includes:
In implementation, after the camera recognizes the recognition result of each preset event included in the monitoring video, the camera may acquire the event occurrence time of the preset event to obtain the first occurrence time of the preset event.
The specific implementation manner of the camera acquiring the event occurrence time of the preset event may be as follows: when the video frame is detected to contain the image information corresponding to the preset event, the camera determines the event occurrence time of the preset event according to the timestamp of the video frame containing the image information corresponding to the preset event. Or when the audio data is detected to contain the voice information corresponding to the preset event, the camera determines the event occurrence time of the preset event according to the timestamp containing the voice information corresponding to the preset event.
In an implementation, the display terminal may store the dynamic visual information and the first occurrence time of the preset event when displaying the dynamic visual information, thereby obtaining a relationship between the dynamic visual information and the occurrence time of the preset event.
In implementation, when the historical dynamic visual information is displayed in the preset display page, the user may perform a preset operation so that the display terminal receives a playback instruction corresponding to the historical dynamic visual information. The preset operation is, for example, clicking an icon of the historical dynamic visual information, or clicking the icon of the historical dynamic visual information to select a preset 'playback' option in the jumping option menu.
Then, the display terminal may determine the occurrence time corresponding to the historical dynamic visual information according to the historical dynamic visual information, the corresponding relationship between the dynamic visual information and the occurrence time of the event, and obtain a second occurrence time of the event to which the historical dynamic visual information belongs.
And step 304, displaying the monitoring video corresponding to the second occurrence time.
In implementation, the display terminal may determine the monitoring video corresponding to the second occurrence time, and then display the monitoring video corresponding to the second occurrence time in a preset display page.
For example, in the preset display page as shown in fig. 2b, if the user clicks the historical dynamic visual information "wane", the display terminal may receive a playback instruction corresponding to the historical dynamic visual information "wane", and then, the display terminal may determine that the second occurrence time of the event dog to which the historical dynamic visual information belongs is 7 am according to the corresponding relationship of the historical dynamic visual information "wane", the dynamic visual information, and the occurrence time of the preset event. Thereafter, the display terminal may display the monitoring video at 7 am in a preset display page.
In the embodiment of the application, the display terminal can establish the corresponding relation between the dynamic visual information and the occurrence time of the preset event.
