Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] refer to Figure 1 to Figure 5 An all-weather multi-channel traffic monitoring system based on wireless infrared monitoring includes an infrared video acquisition terminal 1 based on an embedded ARM platform and a central information server terminal 2. The embedded video monitoring terminal performs real-time video acquisition and monitoring of corresponding channels. Preliminary preprocessing of video; on the central server side of the system, the statistics of the corresponding video traffic and the summary of all the traffic of all channels are performed on the preprocessed surveillance video sent by each video collection terminal. A wireless network 3 such as WiFi is used to realize connection and communication between the video acquisition terminal 1 and the central server end 2 .

[0033] Video acquisition terminal: Based on the above system architecture,...

Abstract

The invention discloses an all-weather multipath channel pedestrian flow monitoring system based on wireless infrared monitoring. The system comprises a video acquisition terminal, wherein the video acquisition terminal comprises active infrared monitoring cameras and video acquisition modules both installed at the inlets of various pedestrian flow monitoring channels, a codebook background module, an image preprocessing module and a wireless transmission module; and the system further comprises: a central server terminal for receiving acquired pedestrian flow data and performing projection, tracking and counting, wherein the central server terminal comprises a wireless reception module, a new pedestrian flow detection module and a pedestrian flow tracking and counting module. The invention provides an all-weather multipath channel pedestrian flow monitoring system based on wireless infrared monitoring, with excellent self-adaptive ability and outstanding reliability.

Description

technical field [0001] The invention relates to monitoring technology in the field of computer vision, in particular to an all-weather multi-channel human flow monitoring system. Background technique [0002] With the continuous progress of society, the application scope of video surveillance system is more and more extensive. Monitoring equipment is usually installed at the entrances and exits of public places such as supermarkets, subways, docks, and stations. Through these monitoring equipment, managers can understand and grasp the safe operation of the monitoring area in real time. However, with the increase of the flow of people in the channel, the manager often needs to grasp the information of the flow of people in the corresponding channel within a certain period of time. There are mainly the following methods for this need: [0003] The first is through manual counting. On the one hand, this method needs to consume human resources for a long time; on the other h...
