Problems solved by technology
[0004] However, in the digital age, the amount of surveillance video data is showing an explosive growth trend. People need to go back and watch a large number of lengthy surveillance videos and find target information from them, which consumes time, manpower, and material resources, and is inefficient. Lag, missed viewing, wrong viewing, etc. have brought great difficulties to the retrospective work of surveillance video, and often lead to missing the best event tracing time

The invention provides a video backtracking method and device, electronic equipment and a readable storage medium. The method comprises the following steps: according to personnel characteristic information extracted from a video stream acquired by an acquisition device, establishing video indexes, obtaining a personnel retrieval request according to the obtained personnel retrieval request; executing retrieval operation on the video index; therefore, the target video picture can be called from the video stream according to the retrieval result, and the target video picture is retrieved basedon the video index because the data volume contained in the established video index is far less than that of the video stream data, so that the target video picture can be quickly and accurately searched, and the video backtracking efficiency is effectively improved.
Description
technical field [0001] The present application relates to the technical field of community security, and in particular, the present application relates to a video backtracking method, device, electronic equipment and readable storage medium. Background technique [0002] With the continuous improvement of people's quality of life and cultural level, the issue of community security has attracted more and more attention. Community security work is not only related to the safety of people's lives and property, but also to the harmony and stability of the society.
