Abstract

The invention provides a people counting method based on video image processing. The people counting method comprises the following steps of: 1, acquiring a video stream image of a monitoring region; 2, acquiring pedestrian targets through a frame difference method, and performing math mathematical morphology operation processing on a frame difference result to obtain a pedestrian moving region; 3, partitioning the pedestrian moving region at least one time by a coordinate projection partitioning method to obtain a plurality of sub regions; 4, searching and matching the sub regions of adjacent frames according to central point distances of the sub regions and gray information distribution features; and 5, instantly updating central point position information of the sub regions, storing the information into a storage device to obtain a people counting result by calculating trace information of central points of the sub regions in the monitoring region. By the method, the efficiency and the accuracy for counting people in a public region can be effectively improved in real time.

Description

technical field [0001] The invention belongs to the technical field of video image processing and identification, and in particular relates to a people counting method based on video image processing. Background technique [0002] Today, with the increasing level of information management, the real-time estimation of the number of people, the analysis of the distribution of the passenger flow, the estimation of the degree of crowding, etc. for the places with huge traffic such as supermarkets, shopping malls, stations, banks, etc., has become the first place for public area management. An effective way to obtain manual information. [0003] To solve this problem, relying solely on monitoring equipment or human judgment for processing is far from meeting the needs of efficient management. At the same time, relying on manual judgment often leads to large errors in the judgment of people statistics, and the efficiency is relatively low. [0004] Chinese patent 03109626....
