公交车人流量监测系统设计

针对公交车人流量统计较困难这一问题,设计了一种公交车人流量监测系统。该系统运用计算机图像处理技术,通过对运动图像的分割处理,得出符合人体特征的头像模块,再进行人头椭圆曲线匹配,从而可以准确地辨别出运动物体是否是人体,最后通过监测已确认的人体的运动质心是否越过设定的计数线来实现对车上人数的计数。本系统能够简单、高效地统计出公交车各时段、各站点人流量以及车载乘客人数,为公交车调度提供信息依据,并能实现超载报警功能。

Design of monitoring system of population flow on public bus

A kind of population flow monitoring systems on buses is designed to overcome the difficulty of calculating the population flow by manual work.Using computer image processing technology,this system can acquire head portrait modules that fit human body characteristics by dividing the moving images.Then it can accurately distinguish that one moving target is whether a human body or not by matching the head elliptic curve.Finally it can be realized to count the people number on the bus by monitoring whether the human body’s centroid has crossed the counting line which is set on the bus.It is convenient to count the flows on every time interval or every site with this system,and to obtain passengers’ number,which not only can give an alarm when the bus overloads,but also can provide the information for the public transportation dispatch supplies.6 figs,10 refs.
