Embodiment Construction

[0075] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0076] In this embodiment, people counting is realized based on video monitoring, head detection, and motion estimation and tracking of people's heads, so as to avoid counting errors caused by the difficulty of maintaining enough energy when people are counting people, and taking into account The video surveillance camera is usually set at a relatively high position in the surveillance scene and captures the video obliquely downward, so even if the scene is crowded with people, all the heads are basically visible, and all these heads can be detected in real time, and Continuous tracking is carried out in the video to achieve accurate counting, which can avoid missing the number of people due to the dense flow of people when counting the number of people ...

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,...
