Method and system for calculating passenger crowdedness degree

Abstract

The invention provides a method and system for calculating a passenger crowdedness degree, comprising steps of establishing a video data collection environment, collecting video data of passengers getting on and off, reading collected video data of passengers getting on and off, performing continuous multi-frame pre-processing on the video data, identifying people heads according to the pre-processing result, taking the detected human head as a target object to be tracked by mean value drift, determining the behaviors of getting on and off of the passengers in the area where the target object is positioned and determining the crowdedness degree of the passengers inside the vehicle according to the numbers of the passengers getting on and off. The invention also provides a system for calculating the passenger crowdedness degree. The technical scheme of the invention adopts the pre-processing which can eliminate the static background to overcome the interference on the identification of the head top of the people in the frame image which is caused by the change of the light, and can effectively reduce the false detection, leak detection and mistake detection through limiting the size of the detection window.

Description

technical field [0001] The invention relates to the field of public transportation, in particular to a calculation method and system for passenger congestion. Background technique [0002] With the progress of urbanization, the urban population continues to expand, and the traffic pressure faced by China's large and medium-sized cities is becoming increasingly serious. In some large cities, traffic congestion during peak hours has seriously hindered the sustainable development of cities. An effective means to solve the traffic congestion in the peak period is to encourage urban residents to travel by bus, but the lack of capacity of some bus lines in the peak period limits the enthusiasm of residents to take the bus. The best way to solve the shortage of transport capacity during peak hours is to increase transport capacity, but simply increasing the number of buses on popular routes will lead to excess transport capacity during off-peak periods, which is neither economical...
