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 recognition, in particular to a method for counting people based on video image processing. Background technique [0002] Today, with the increasing level of information management, the real-time estimation of population statistics, analysis of passenger flow distribution, and estimation of crowding degree for places with huge traffic such as supermarkets, shopping malls, stations, and banks have become the first to provide public area management. An effective way of hand data. [0003] To solve this problem, relying solely on monitoring equipment or manual judgment 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 the number of people, and the efficiency is relatively low. [0004] Chinese patent 03109626.3, an invention patent titled "Automatic Technology System for Tiny Insects"...
