Problems solved by technology

[0004] Manual work is inefficient and wastes human resources;
[0005] The mechanical type needs to bury the induction pedal under the passage, and touch the counter to count when people pass by. This method is easy to miss and miscount when people pass through densely;
[0006] Infrared type is to use infrared sensor to sense people when people pass by, and this method is difficult to be sensed by infrared sensor when the flow of people is bl

Embodiment Construction

[0056] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0057] see figure 1 , which is a flow chart of the binocular vision people flow counting method provided by the present invention.

[0058] The people flow statistics method of this binocular vision can carry out accurate people flow statistics to multi-scenario, and it is based on binocular stereo vision, mainly comprises the following several steps (see figure 1 ):

[0059] Step 1: Collect binocular video images, and use binocular cameras to collect left and right images synchronously;

[0060]Step 2: Correction of binocular images. According to the positional relationship between the cameras, the binocular images captured by the parallel binocular cameras are corrected to obtain binocular images parallel to the epipolar lines;

Abstract

The invention provides a multi-scene pedestrian volume counting method and system based on stereoscopic vision and a binocular camera. The pedestrian volume counting method is based on binocular stereoscopic vision, and comprises the following steps: firstly, correcting a binocular image shot by a row-parallel binocular camera to obtain an epipolar-line-parallel binocular image; secondly, performing stereo matching on the corrected binocular image to obtain a parallax image; thirdly, detecting pedestrian targets in the obtained parallax image; and lastly, tracking and counting the targets according to the attribute features of the detection targets. The pedestrian volume counting system consists of the binocular camera, a DSP binocular acquisition and video processing module, a network transmission module and a terminal data analysis module. Through adoption of the pedestrian volume counting method and system provided by the invention, the number of people in different pedestrian volume entrance and exit scenes can be accurately counted, and data support is provided for a decision maker.

Description

technical field [0001] The invention relates to image monitoring and processing technology, in particular to a people flow counting technology based on image processing. Background technique [0002] The statistics of the flow of people can be widely used in public transportation, buses, shopping malls, exhibition halls, building passages and other places that need to count the flow of people, so as to provide indispensable data support for management and decision makers. For places such as buses and buses, the flow of people can assist functional departments to optimize their settings. For the retail industry, the flow of people can be linked with the sales volume, which can be used as a commercial basis for business decision makers. [0003] The current people counting methods are mainly divided into manual, mechanical, infrared and monocular video. These kinds of people counting methods have corresponding problems in practical application: [0004] Manual work is ineffi...
