Problems solved by technology
Therefore, the following two main problems still exist in the compressed video image data: the first, although the compressed video image data is reduced a lot than the original video image data, it still takes a lot of hard disk space, and the storage hardware cost is very high. Second, there are often a lot of still or unchanged video data in the video image data. These are meaningless data. When you need to look up the video image data, you need to browse the data by fast forwarding or dragging. This will not only miss some details, but also take a long time to find the real valuable video image data

[0034] see Figure 7 , Figure 7 It shows the first embodiment of the image data storage method based on video monitoring of the present invention, which includes:
[0035] S101. Acquire video monitoring data in a video monitoring process.
[0036] S102. Extract each frame of image in the video surveillance data.
[0037] Wherein, the image extracted in real time is set as the current frame image, and the previous frame image of the current frame image is set as the preceding frame image.
[0038] It should be noted that video surveillance data is composed of images frame by frame. Assuming that the frame rate of the surveillance camera is 30 frames, that is to say, within one second, the camera will generate 30 consecutive frames of images. The differences provide a lot of reference information.
[0039] S103, comparing each frame of images in sequence to determine whether the video monitoring picture has changed within the preset range, if the video monitoring picture ha...

The invention discloses a method for storing image data based on video monitoring, comprising: acquiring video monitoring data in the process of video monitoring; extracting each frame image in the video monitoring data, and setting the image extracted in real time as the current frame image, and setting The previous frame image of the current frame image is set as the front frame image; each frame image is compared in turn to determine whether the video monitoring picture changes within the preset range, if the video monitoring picture has changed within the preset range If there is a change, the current frame image will be stored, and if the video monitoring screen does not change within the preset range, the current frame image will be discarded. The invention also discloses an image data storage system based on video monitoring. By adopting the present invention, the effective filtering of still or unchanging video data can be realized, the storage capacity of video image data can be greatly reduced, and the time spent on checking videos can be reduced, and work efficiency can be improved.
Description
technical field [0001] The invention relates to the technical field of multimedia information processing, in particular to a video monitoring-based image data storage method and a video monitoring-based image data storage system. Background technique [0002] With the continuous development of video surveillance technology, video surveillance has played an important role in anti-theft and social security monitoring. A large number of video surveillance cameras are all over the streets and alleys. Many factories or enterprises have also installed surveillance cameras, and even individual families A camera is also installed. [0003] Such as figure 1 As shown, a large number of cameras will inevitably produce a large amount of video image data. Before the compression algorithm is used to compress the original video image data, all the original video image data is in an uncompressed state to maintain the accuracy of the video image data. [0004] Such as figure 2 As shown, ...
