Embodiment Construction

[0041] In order to make those skilled in the art better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to specific embodiments.

[0042] like figure 1 As shown, the present invention provides a method for monitoring the loitering behavior of a person, comprising:

[0043] S1 collects video and analyzes the video frame by frame to identify pedestrians in each frame of image;

[0044] S2 judges whether the identified pedestrian is a real pedestrian;

[0045] S3 generates the trajectory of the same target pedestrian in the video collection area;

[0046] S4 grids the video collection area together with the pedestrian trajectory, calculates the distance of the pedestrian trajectory moving in each direction in each grid and compares the maximum value, and counts the direction to which the maximum pedestrian trajectory movement distance in all grids belongs;

[0047] S5 judges whether the...

Abstract

The invention discloses a personnel wandering behavior monitoring method and system, and the method comprises the steps: collecting a video, carrying out the frame-by-frame analysis of the video, and recognizing pedestrians in each frame of image; judging whether the identified pedestrian is a real pedestrian or not; generating a track of the same target pedestrian in the video acquisition area; gridding the video acquisition area and the pedestrian track, calculating the moving distance of the pedestrian track in each grid in each direction, comparing the moving distance with the maximum value, and counting the direction to which the moving distance maximum value of the pedestrian track in all grids belongs; and whether the pedestrians wander or not is judged by comparing the number of times of occurrence in the directions with the maximum pedestrian trajectory movement distances in all the grids with a threshold value. The method has low requirements on video resolution and definition. The method for judging the number of times of the gridding main motion direction is few in operation steps, simple in process, accurate in result and practical.

Description

technical field [0001] The present invention relates to a method and system for monitoring the loitering behavior of people. Background technique [0002] There are certain security risks in some public places such as banks, schools, government offices, embassies, cultural and religious gathering places, high-security perimeters, commercial areas and residential areas. Before committing criminal acts, such criminals often step on the target site, move around the site, and linger. Therefore, its activity trajectory has obvious wandering characteristics. By detecting and alarming wandering people, it can provide timely warning to the police or arrange personnel, and timely find the target that needs to be marked. [0003] The existing monitoring technology for pedestrian wandering behavior is difficult to recall, and it is extremely harsh on the trajectory of wandering pedestrians. In practical projects, it is difficult to implement. SUMMARY OF THE INVENTION [0004] In vi...
