As we all know, the video surveillance system has experienced three stages of development and evolution from the first generation analog system, to the second generation partly digitalized system, and then to the second generation fully digitalized system. During this process, the video surveillance system Although the functions and performance of the equipment have been greatly improved, they are still limited by some inherent factors, including the physical weakness of human beings as monitors, as well as the configuration of video surveillance systems and video surveillance equipment. Limitations in functionality and performance
In the case of a large amount of video data, users need to watch the information they want to watch, and often need to watch the entire video, which increases the time for users to watch the video, and sometimes, the video may not include the content the user needs

Embodiment Construction
[0014] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0015] see figure 1 with figure 2 , a camera video summary generation system, comprising the following steps:
[0016] a. Camera video processing 1: Obtain the real-time video stream 10 and recorded video 9 captured by the camera 5 .
[0017] b. Key frame processing 2: Analyze the real-time video stream 10 and recorded video 9 captured by the camera 5 frame by frame and compare them with the event conditions, extract the changed objects in a single frame that meet the event conditions as object screenshots 6 and capture the object The position coordinates on the single-frame image are extracted as object coordinates until all single-frame an...

The invention discloses a generation system for a video abstract of a camera. The generation system comprises the following steps that a real-time video stream and a picture-recording video shot by the camera are analyzed frame by frame, and compared with event conditions; a changing object in a single frame, which meets the event conditions, is extracted as an object screenshot; position coordinates of the object on the single frame, are extracted as object coordinates; a plurality of object screenshots and object coordinates are obtained until the whole single-frame analysis is accomplished; the object screenshots are expressed as one or more abstract pictures according to the amount of the object screenshots and the object coordinates; the object screenshots close to the object coordinates are displayed in the different abstract pictures; and the abstract pictures generated corresponding to a video are expressed as a plurality of thumbnails corresponding to the video. According to the generation system of the video abstract of the camera, the main content in the video shot by the camera can be known immediately.
Description
technical field [0001] The invention relates to the field of video analysis, in particular to a camera video summary generation system. Background technique [0002] With the rapid development of computer network and multimedia technology, the application of multimedia data is becoming more and more extensive. As we all know, the video surveillance system has experienced three stages of development and evolution from the first generation analog system, to the second generation partly digitalized system, and then to the second generation fully digitalized system. During this process, the video surveillance system Although the functions and performance of the equipment have been greatly improved, they are still limited by some inherent factors, including the physical weakness of human beings as monitors, as well as the configuration of video surveillance systems and video surveillance equipment. Limitations in functionality and performance. In the case of a large amount of v...
