Video monitoring method and system with auxiliary objective monitoring function

Abstract

A video monitoring method that has auxiliary monitoring function for an object is provided, which comprises the following procedures: a) collecting images in a target area; b) identifying and tracking a monitoring object in the image of target area, so as to acquire the number and / or movement information about the monitoring object; c) carrying out comprehensive statistics and analysis of passenger flow according to the acquired number and / or movement information about the monitoring object. The invention can intelligently assist a safety administrator to manage, so as to effectively reduce the potential safety hazard and save a great amount of management manpower. What is more, with unique background updating mechanism, the invention can ensure more reliable application in places with great passenger flow such as the platform of rail transit, the entrance of department store and entrance of passage. In addition, by tracking the monitoring object according to different passenger flow, the invention not only simplifies the elaborated tracking algorithm, but also ensures better processing effect.

Description

technical field [0001] The invention relates to security monitoring technology in the field of computer vision, in particular to a video monitoring method and system. Background technique [0002] Rail transit in modern cities is a very convenient mode of transportation. It is not affected by weather and traffic conditions, and can carry passengers to their destinations on time. Therefore, people like to choose rail transit as a way of travel. However, due to the large population in the city, most people want to arrive at their destination on time, so the passenger flow of rail transit is very large. Usually on the platform, especially at the screen door where boarding and disembarking, it is a crowded place, and it is also the place where safety accidents are most likely to occur. It takes a lot of human energy to use security personnel for human management, and because of the crowd, it is easy to overlook some invisible situations. [0003] The existing people counting s...
