Research On Safety Intelligent Monitoring Of Passenger Flow In Station Based On Machine Vision

Under the new security situation,how to effectively monitor the passenger flow status of the railway passenger terminal and ensure the safe production is an important concern of the railway station management department.Vision research station passenger flow security issues in computer application.Computer vision research on station passenger flow safety is also the focus of current research.At present,the monitoring system of railway passenger station in our country has many shortcomings in monitoring facilities layout,intelligent management and so on.It is difficult to meet the safety management demand of railway station passenger flow.In this case,the intelligent station monitoring system has important practical significance for ensuring the safety of passenger flow and safety of the station and improving the emergency management ability of the station.On the basis of extensive research on the current situation of station monitoring at home and abroad,The existing research theories and achievements of station monitoring point layout,target detection and tracking,passenger flow safety status identification are reviewed.Fully combining the actual needs of passenger flow safety monitoring at railway stations,the following research works are carried out:(1)Based on analyzing the functions of different regions and the flow lines of passenger flow in the station,the three level layout method of monitoring camera with "point","line" and "surface" is put forward.By comparing and analyzing the new method,the monitoring of dead angle can be reduced and the efficiency of monitoring can be improved.(2)According to the in-depth study of the image processing and target segmentation tracking algorithm,the multi target detection and tracking location is realized by the machine vision method to realize the development of the station passenger flow intelligent monitoring and control system.(3)Aiming at the safety management requirement of station passenger flow,constructing passenger flow safety early warning index system,designing passenger flow detection early warning program and station simulation scene,realizing the identification of simulation passenger flow state,verifying the reliability and effectiveness of passenger flow detection algorithm,providing technical support for safety and active prevention and control of station passenger flow.
