Embodiment Construction

[0023] The RGB-D-based pedestrian trailing detection method provided by the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as figure 1 — image 3 Shown, the pedestrian trailing detection method based on RGB-D provided by the present invention comprises the following steps carried out in order:

[0025] 1) Build as figure 1 As shown, the color camera 1 and the depth camera 2 are arranged side by side directly above the monitoring channel 3 with the monitoring angle of view vertically downward. The distance between the color camera 1 and the depth camera should be as close as possible to reduce the The interference caused by the range; at the same time, the straight line where the color camera 1 and the depth camera 2 are located is perpendicular to the length direction of the monitoring channel 3 in the monitoring scene, and the RGB image and the depth image in the monitoring channel 3 ...

Abstract

Provided is a pedestrian trailing detection method based on RGB-D. The method comprises the steps that a foreground target is detected firstly through a depth image in a monitor area, then a human head target is precisely detected and located according to hair color information and depth outline information of the head and the shoulders, finally, the human head target is trailed through a camshaft algorithm, and then whether a trailing phenomenon occurs or not is judged. According to the method, pedestrians and luggage can be effectively recognized, the pedestrians can be precisely counted, the pedestrians cannot be mistaken for the luggage, the luggage cannot be mistaken for the pedestrians, high detection precision is achieved on the multi-people trailing phenomenon, and the method is especially suitable for the occasions, such as entrance guards, station security checkpoints and enterprise access channels.

Description

technical field [0001] The invention belongs to the technical field of intelligent monitoring, in particular to an RGB-D-based pedestrian trailing detection method. Background technique [0002] With the rapid development of computer vision technology, intelligent monitoring has a wide range of applications in the fields of security, security inspection, and traffic management, such as license plate number inspection, pedestrian or vehicle traffic violation detection, and visual access control. Intelligent monitoring can not only reduce the cost of human monitoring, but also an important manifestation of urban civilization. [0003] In the past, we often saw reports of accidents such as subway gates pinching passengers. The main reason is that the existing system cannot distinguish between pedestrians and luggage, and it cannot distinguish how many people passed after swiping the card. If the passenger swipes the card and pushes the luggage through Turnstiles, it is very li...
