Problems solved by technology

[0003] At present, the intelligent video analysis system is still a relatively new technology. The circle of people who understand this technology in China has only expanded to the level of integrators, so many application scenarios suitable for video analysis technology have yet to be developed by the market; and now people use it most. Relying on manual counting of the flow of people, the counting is inaccurate and the cost is high

Abstract

The invention discloses a method and system for detecting pedestrian flow based on machine vision. The main technical characteristics of the system are that the system is composed of a video collecting module, an image preprocessing module, an intelligent video analyzing server, a transmission module, a monitoring center, a video decoder, a displayer and a printer, wherein the video collecting module is connected with the intelligent video analyzing server through the image preprocessing module, the transmission module is connected with the monitoring center, and the video decoder is connected with the printer through the displayer. The system has reasonable design; for the system, the image preprocessing module is used for carrying out three-step detecting extraction on images collected by the video collecting module, and the intelligent video analyzing server is used for analyzing the extracted image information, and therefore, the accuracy of pedestrian flow data is greatly increased while the intellectualization of the system is realized; and the system can be widely applied to places such as subway stations, bus stations, airports, tourist fields, national key protected scenic spots and the like.

Description

Technical field [0001] The invention belongs to the field of pedestrian flow detection, in particular to a method and system for pedestrian flow detection based on machine vision. Background technique [0002] With the advancement of society and the development of technology, people have new requirements for pedestrian flow detection methods. Not only are they required to accurately record the flow of people, but the entire system is also required to be simple to operate. From an algorithm perspective, pedestrian flow detection methods can be simply divided into two categories: One is to establish a background model, and to find moving objects by comparing with the background model. The other is to use the "optical flow" method to find moving objects by discovering the influence of moving objects on the optical flow field. The other is a method between the two or a combination of the two. The background model method is relatively complete in the extraction of moving objects, wh...
