Abstract

The embodiment of the present application provides an artificial intelligence-based video monitoring method and system, the method includes: S1, setting the prior probability P of the camera for the appearance of a person event i，j ; S2. Determine the frame sampling frequency f for character events according to the probability P i，j ; S3, the camera follows the frame rate F of the camera i , extract images from the video, analyze them in real time and save and upload them, and get the probability of occurrence P′ i，j ; S4. Judging the occurrence probability of character events P′ i，j Is it greater than the prior probability P i，j , if yes, judge whether further verification is needed, if not, then update the probability P to the occurrence probability P′ i，j , and return to step S2. The system includes: data acquisition equipment and data processing equipment. The data acquisition equipment is used to: collect character event information, and extract the character event information and send it to the data processing device; the data processing device is used to: generate processing results based on the character event information and feed back to data acquisition equipment. Realized the dynamic adjustment of the frame rate of the front-end camera to improve the accuracy of event detection.

Description

technical field [0001] The present application relates to the technical field of video surveillance and security, in particular to an artificial intelligence-based video surveillance method and system. Background technique [0002] With the continuous acceleration of the development of urban modernization, the relative lag of urban management has become a prominent common problem. With the rapid development of science and technology today, society has entered the era of digitalization and informationization, and the use of high-tech to prevent, stop, and combat crimes has gradually taken up more and more positions in the three major prevention methods (namely, human defense, system defense, and technical defense). important dominance. Therefore, video surveillance has become a powerful starting point for improving urban public service capabilities and enhancing urban management. [0003] At present, video surveillance systems have been widely used in public security, traff...
