The storage device may be a memory provided in the alarm server, or may be a cloud storage server in the alarm system. The method comprises the steps that a video acquisition device acquires videos in real time and sends the videos acquired in real time to a storage device, the storage device stores the videos acquired in real time by the video acquisition device, the videos acquired in real time comprise information such as timestamps acquired by the videos, when an alarm event meeting alarm conditions is detected to occur, the video acquisition device pushes alarm information of the alarm event to an alarm server, wherein the alarm information comprises a unique identifier of the alarm event, the unique identifier of the alarm event can be used for identifying pictures when the alarm event occurs, and the pictures can be time, picture numbers, frame sequence numbers and the like. For example, the unique identifier of the alarm event is a current timestamp of a video being acquired when the alarm event meeting the alarm condition is detected, the timestamp is used as the unique identifier of the alarm event, and the timestamp is used for identifying a picture when the alarm event occurs.
The video acquisition equipment detects various alarm events meeting the alarm conditions. For example, when, from the captured video, a face image of the target person is detected, an image of a fire is detected from the captured video, an image in which a motion suddenly appears from the captured video or an image in which a long-time still is detected, or the like. In addition, the video capture device detects alarm events and may also be independent of the captured video. For example, the video capture device may be equipped with various types of sensors that detect the occurrence of an alarm event that meets an alarm condition when the installed sensors detect smoke, abnormal temperature, and/or abnormal vibration.

In an alternative to this implementation, the alert server itself may have a software controlled platform, and the user may be an administrator of the software controlled platform. In the software interface of the software control platform, the alarm information of the alarm event received by the alarm server can be displayed; therefore, when the user of the software control platform selects the option of viewing the alarm picture of the alarm event in the software interface of the software control platform, the alarm server can respond to the request sent by the user, and then extract the picture corresponding to the unique identifier of the alarm event from the video stored in the storage device according to the alarm information to serve as the alarm picture of the alarm event.
Furthermore, according to actual needs, the alarm server may also automatically extract, according to a preset rule, a picture corresponding to the unique identifier of the alarm event from a video stored in the storage device, as an alarm picture of the alarm event, and further push the alarm picture of the alarm event to a preset client, such as a monitoring platform or a mobile phone of a user. For example, the only identifier of the alarm event is an alarm timestamp, and after the alarm information is received, a picture corresponding to the alarm timestamp is extracted from the video stored in the storage device within a specified time range according to a preset rule to serve as an alarm picture of the alarm event. And after the alarm server extracts the alarm picture, the extracted alarm picture can be stored, sent and/or displayed.
The alarm server may further include other information, for example, the device model of the video capture device that pushes the alarm information, the installation location of the video capture device that pushes the alarm information, the specific type of the alarm event, and the like, and the user may flexibly use the information according to the actual requirements, for example, the installation location of the video capture device that pushes the alarm information is used to locate the place where the alarm event occurs, and other services are deployed according to the located place where the alarm event occurs, which is not described herein again specifically.
The embodiment of the invention provides a video alarm method, wherein a video acquisition device acquires a video in real time and stores the video in a storage device, and when the video acquisition device detects that an alarm event meeting alarm conditions occurs, alarm information of the alarm event comprising a unique identifier of the alarm event is pushed to an alarm server to realize alarm. And after receiving the alarm information, the alarm server extracts a picture corresponding to the unique identifier of the alarm event from the video stored in the storage device according to a preset request instruction and the alarm information, and the picture is used as an alarm picture of the alarm event. Therefore, in the scheme, the video acquisition equipment does not need to shoot the alarm picture, correspondingly does not need to store the alarm picture into the storage equipment, and the alarm server acquires the alarm picture of the alarm event according to the unique identifier of the alarm event in the alarm information; therefore, the occupation of the bandwidth resources of the video acquisition equipment is reduced.
In a possible implementation manner, the extracting, according to a preset request instruction and the alarm information, a picture corresponding to the unique identifier of the alarm event from a video stored in the storage device as an alarm picture of the alarm event includes:
step A, the alarm server sends a preset request instruction and the alarm information to the storage device;
step B, the storage device acquires a video corresponding to the unique identifier of the alarm event from a stored video according to the preset request instruction and the alarm information, and sends the video corresponding to the unique identifier of the alarm event to the alarm server;
and step C, the alarm server extracts a picture corresponding to the unique identifier of the alarm event from the video corresponding to the unique identifier of the alarm event as the alarm picture of the alarm event according to the unique identifier of the alarm event.
Specifically, after the storage device receives a preset request instruction and the alarm information sent by the alarm server, the storage device obtains a video corresponding to the unique identifier of the alarm event from a stored video according to the preset request instruction and the alarm information, the storage device sends the video corresponding to the unique identifier of the alarm event to the alarm server, and the alarm server extracts a picture corresponding to the unique identifier of the alarm event from the video corresponding to the unique identifier of the alarm event as an alarm picture of the alarm event according to the unique identifier of the alarm event. The video corresponding to the unique identifier of the alarm event can be a video code stream with the smallest video storage unit, so that not only can the bandwidth for communication between the storage device and the alarm server be saved, but also the calculation amount is reduced and the time for extracting the picture corresponding to the unique identifier of the alarm event is shortened in the process that the alarm server extracts the picture corresponding to the unique identifier of the alarm event from the video corresponding to the unique identifier of the alarm event.
In a possible implementation manner, the extracting, according to a preset request instruction and the alarm information, a picture corresponding to the unique identifier of the alarm event from a video stored in the storage device as an alarm picture of the alarm event includes:
step one, the alarm server sends a preset request instruction and the alarm information to the storage device;
step two, the storage equipment acquires a video corresponding to the unique identifier of the alarm event from a stored video according to the preset request instruction and the alarm information;
step three, the storage device extracts a picture corresponding to the unique identifier of the alarm event from a video corresponding to the unique identifier of the alarm event as an alarm picture of the alarm event according to the unique identifier of the alarm event;
and step four, the storage equipment sends the alarm picture of the alarm event to the alarm server.
The alarm server sends a preset request instruction and the alarm information to the storage device, the storage device acquires a video corresponding to the unique identifier of the alarm event from a stored video according to the preset request instruction and the alarm information, then the storage device extracts a picture corresponding to the unique identifier of the alarm event from the video corresponding to the unique identifier of the alarm event as an alarm picture of the alarm event according to the unique identifier of the alarm event, and finally the storage device sends the alarm picture of the alarm event to the alarm server so that the extraction of the picture corresponding to the unique identifier of the alarm event is completed in the storage device, and finally the storage device only needs to send the alarm picture of the alarm event to the alarm server without sending the video corresponding to the unique identifier of the alarm event to the alarm server, therefore, the occupation of bandwidth resources in the process of sending the storage equipment to the alarm server is saved.
In a possible implementation manner, the alarm information further includes an identifier of the video capture device;
the extracting, by the alert server, a picture corresponding to the unique identifier of the alert event from the video stored in the storage device as the alert picture of the alert event includes:
the alarm server acquires the corresponding video sent by the video acquisition equipment from the videos stored in the storage equipment according to the identification of the video acquisition equipment;
and the alarm server extracts a picture corresponding to the unique identifier of the alarm event from the corresponding video sent by the video acquisition equipment as the alarm picture of the alarm event according to the unique identifier of the alarm event.
When the alarm information comprises the identification of the video acquisition equipment, the alarm server acquires the corresponding video sent by the video acquisition equipment from the video stored in the storage equipment according to the identification of the video acquisition equipment, so that when a plurality of video acquisition equipment exist, the corresponding video sent by the video acquisition equipment can be acquired from the video stored in the storage equipment, and finally, the alarm server extracts the picture corresponding to the unique identification of the alarm event from the corresponding video sent by the video acquisition equipment according to the unique identification of the alarm event as the alarm picture of the alarm event, so that the accuracy of extracting the alarm picture of the alarm event can be improved, and the time for extracting the alarm picture of the alarm event can be shortened.
In a possible implementation manner, the extracting, from the video stored in the storage device, a picture corresponding to the unique identifier of the alarm event as the alarm picture of the alarm event includes:
acquiring a picture group covered with the unique identifier of the alarm event from the video stored in the storage device;
and extracting the picture corresponding to the unique identifier of the alarm event from the picture group, and generating a thumbnail as an alarm picture of the alarm event.
For example, the only identifier of the alarm event is an alarm timestamp, and the alarm server may obtain, from the video stored in the storage device, a group of pictures covered with the time point indicated by the alarm timestamp; then, extracting the picture corresponding to the alarm time stamp from the picture group, and generating a thumbnail as an alarm picture of the alarm event. Wherein a group of pictures is commonly referred to as a gop (group pictures). It is to be understood that the videos stored in the storage device by the video capture device may be videos that are captured continuously in units of a predetermined time period or a predetermined file size, each of the videos being composed of a plurality of GOPs. Therefore, the alarm server can obtain the picture group covered with the unique identifier of the alarm event according to the unique identifier of the alarm event, so that the picture corresponding to the unique identifier of the alarm event can be extracted from the picture group, and a thumbnail is generated to be used as the alarm picture of the alarm event. The specific implementation mode of the alarm picture as the alarm event also exists in various ways. For example, the alarm server may extract the nearest one of the frames indicated by the unique identifier of the alarm event from the group of frames, and generate a thumbnail as an alarm picture of the alarm event.
For example, the unique identifier of the alarm event is an alarm timestamp, and it is understood that since the video captured by the video capture device is continuous, there may be at least tens of frames per second; therefore, the time between the shooting time point of the alarm picture extracted by the alarm server and the time point indicated by the alarm time stamp can be at least less than 1 second. Therefore, the alarm picture acquired by the alarm server can accurately display the image when the alarm event occurs. Or, the warning server may determine, from the group of pictures, one picture whose shooting time point is closest to the time point indicated by the warning timestamp; and extracting the picture and a preset number of pictures before and after the picture, and respectively generating thumbnails as alarm pictures of the alarm events. In this implementation, the number of subscriptions may be, but is not limited to, 1, 2, or 3, etc. It can be understood that the number of the extracted alarm pictures is increased, and the information which can be provided by the alarm pictures can be enriched, so that the images of the alarm events to which the alarm pictures belong can be displayed more comprehensively. In addition, after the alarm server extracts the pictures from the picture group, a clear alarm large picture can be generated to be used as an alarm picture of an alarm event. Regarding the generation mode of the thumbnail or the alarm large image, the existing generation mode of the thumbnail or the alarm large image may be referred to, and details are not repeated in the present invention.
In a possible implementation manner, after the step of receiving, by the alert server, the alert information sent by the video capture device, the method further includes:
and the alarm server sends the alarm information to a preset client so that a user can check the alarm information through the preset client.
After receiving the alarm information, the alarm server may send the alarm information to a preset client, so that a user views the alarm information through the preset client, and then the user flexibly uses the alarm information according to actual needs, for example, sends an instruction for viewing an alarm picture according to the alarm information, and the like.
