Embodiment Construction

[0054] The present invention will be described in detail below in conjunction with the implementations shown in the drawings, but it should be noted that these implementations are not limitations of the present invention, and those of ordinary skill in the art based on the functions, methods, or structural changes made by these implementations Equivalent transformations or substitutions all fall within the protection scope of the present invention.

[0055] ginseng figure 1 as shown, figure 1 It is a schematic flowchart of a method for counting male and female pedestrians in the present invention. In this embodiment, a method for counting pedestrians of men and women, the method for counting the number of men and women includes the following steps:

[0056] Firstly, step S1 is executed, and the video stream image of the monitoring area is acquired as an input image.

[0057] ginseng figure 2 As shown, this step S1 is specifically: the video stream image of the monitoring ...

Abstract

The invention discloses a statistical method for male and female passenger flow, comprising the following steps: S1, acquiring a video stream image of a monitoring area as an input image; S2, using a classifier to perform face detection on the input image to obtain a candidate face area, and Plan the rectangular area above the head; S3, according to the number S of dark pixels in the rectangular area above the head dark and the total number of pixels S all The ratio of the non-face area is eliminated to obtain the pedestrian area containing the face area; S4, at least correlating the color histogram measurement of the chest rectangular area corresponding to the pedestrian area containing the face area in the adjacent frame input image , to track the center of the face area in step S3; S5, normalize the size of the face area to obtain a fixed-size face image, use a gender classifier to identify men and women, and record the number of male and female passengers. The invention not only reduces the false detection rate but also improves the efficiency of counting the passenger flow of men and women.

Description

technical field [0001] The invention belongs to the technical field of video image processing and recognition, and in particular relates to a statistical method for male and female passenger flows. Background technique [0002] Video-based intelligent monitoring system is an important branch of machine vision and has broad application prospects. It plays a huge role in security prevention and control fields such as public place monitoring and road traffic monitoring. For most security prevention and control fields, moving targets such as people, animals, and vehicles in the monitoring scene are obviously the main objects of concern. Pedestrians are the most active and main part, so the detection, identification and statistics of pedestrians have very important research value. [0003] In terms of pedestrian detection, pedestrian flow data play a very important role in the management and decision-making of public places such as shopping malls, shopping centers, and transpor...
