Demographic method and system based on video monitoring

Abstract

The invention discloses a person number counting method and a system based on video monitoring. Based on video monitoring, the person number counting method can count the person number by detecting heads and estimating and tracking the movement of the heads, and can obviate counting error of manual counting due to the lack of energy. Because a video monitoring camera is usually arranged at a higher position and faces downwards slantwise in the monitored scene, the heads of all persons are visible basically and can be detected on a real-time basis even in a people-concentrated scene, so that the accurate counting can be achieved by continuously tracking the heads in the video, thereby obviating missing counting by manual counting in the people-concentrated scene.

Description

technical field [0001] The invention relates to video monitoring technology, in particular to a method for counting people based on video monitoring and a system for counting people based on video monitoring. Background technique [0002] In scenes such as supermarkets, office buildings, and subway entrances and exits, cameras of video surveillance systems are usually installed to implement video monitoring of supermarkets, office buildings, and subway entrances and exits. [0003] At the same time, for some specific needs, in the above scenarios, it is usually necessary to count the number of people entering and leaving. However, the video surveillance in the prior art cannot realize the counting of people, so the above-mentioned counting usually needs to be completed by people. [0004] However, because it is difficult for the person who completes the above statistics to concentrate on keeping an accurate count of the number of people entering and leaving for a long time,...

However, the video surveillance in the prior art cannot realize people counting, so the above-mentioned counting usually needs to be completed by people

[0004] However, because it is difficult for the person who completes the above statistics to concentrate on keeping an accurate count of the number of people entering and leaving for a long time, and it is easy to miss the number of people when the flow of people is dense, it is not only labor-intensive to realize the number of people counting, but also the accuracy of the number of people counting is not good. high
