Problems solved by technology

This mechanical method has high construction costs, huge equipment investment, and large equipment. It is usually fixed at the entrance and exit, which is not flexible enough to use, and it is not convenient enough to manage the flow of people. Another biggest disadvantage is that it hinders speed of travel

Abstract

The invention belongs to the technical field of machine vision, and provides a pedestrian counting method based on head detection. The method comprises that S1) multiple training sample sets are trained by an SVM classifier to obtain multiple head classifiers; S2) a video stream image of a monitoring area is obtained and used as an input image; S3) a frame difference method is used to calculate the frame difference of the input image and further to obtain a moving pedestrian area; S4) the head classifiers are used to detect the moving pedestrian area to obtain a head area; and S5) a Kalman nearest neighbor coupling tracking method is used to track and count central points of the head area. According to the invention, the SVM classifier is used for training to obtain the multiple head classifiers, the head classifiers are used to detect the moving pedestrian area to obtain the head area, and the alman nearest neighbor coupling tracking method is used to track and count the central points of the head area; and thus, the calculation efficiency and accuracy of the number of pedestrians in a public area is improved.

Description

technical field [0001] The invention belongs to the technical field of computer vision, and more particularly relates to a pedestrian counting method based on head detection. Background technique [0002] In many industries, people flow information can provide a key basis for people flow management, resource management, and management decisions. For example, in subway stations, pedestrian counting can be used to understand the size of the flow of people at each station in real time, flexibly schedule the density of subway trains, implement flow control, and release information on densely populated areas in real time, which is conducive to enhancing the efficiency of crowd transportation and ensuring smooth and effective subway operations. [0003] In a shopping mall, the flow of people is an important basis for reflecting its commercial value. Accurate calculation of the flow of people is conducive to grasping the shopping preferences of customers, so as to achieve better lo...
