Abstract

The invention discloses a frame extraction dynamic scheduling method and system for examination video violation analysis. The system comprises a retrieval module, an image frame extraction module, animage storage module, a message notification module and a short video extraction module. The retrieval module retrieves a local disk and an external disk, and sends the retrieved video file to the image frame extraction module; the image frame extracting module is used for extracting and decoding the received video file and sending the decoded video frame to the image storage module; the image storage module encodes the video frame and generates a picture file; the message notification module reports the received message to the short video extraction module; and the short video extraction module extracts a standard short video at the corresponding position of the file according to the video frame time and the serial number. According to the invention, video frame decoding is carried out byadopting a hard decoding mode, so that the video file processing speed is increased; three frame extraction strategies are configured, the frame extraction strategies can be updated at any time, andquick imaging of video files is achieved.

Description

technical field [0001] The invention relates to the field of video analysis, in particular to a method and system for dynamic scheduling of frame extraction for analysis of examination video violations. Background technique [0002] With the popularity of smart products, video has become a way of information exchange commonly used in our daily life. Various businesses and enterprises have also invested a lot of effort in the field of video analysis; video frame sampling is an essential part of video analysis. Its applications include: road condition analysis, behavior analysis, examination video violation analysis, etc. Its main working principle is to use image frame extraction technology to extract a single image from the video and feed it back to the client . However, the traditional video frame extraction cannot update the frame extraction strategy at any time, and often takes a long time to complete, the frame extraction rate is low, and it is impossible to quickly ima...
