Frame extraction optimization method and system based on video stream intelligent analysis scene

The invention discloses a frame taking optimization method and system based on a video stream intelligent analysis scene, and relates to the technical field of video stream intelligent analysis, and the method comprises the steps: carrying out the traversal detection of all cameras and models on a server, defining a frame taking period, and carrying out the grouping of camera configuration according to the demands; distributing a video stream group for each second in a frame taking period, calculating the maximum frame taking number of each camera, and taking frames according to the number; and generating a next segment of sequence based on the camera sequence, and carrying out merging operation before generating the frame taking sequence. According to the method, the burden of a server is relieved by dynamically distributing video stream groups, the resource utilization rate is optimized and the recognition efficiency is improved by calculating and controlling the number of frames, interruption and repeated
