The Gate Transit Logic based on Detecting Human Head and Shoulder
Grg Banking · 2008
The algorithm of gate recognition in urban rail transit is mainly applied in automatic fare collection(AFC) system.The gate provides services for passengers directly,so its security,reliability,accuracy and stability are very important for the service quality of AFC.The author analyzes the logic problems in existing gate recognition,points out that these problems make the gate working ineffectively and unfriendly in specific and abnormal situations.These problems also initiate disorder in ticketing accounts and the loss of tickets.The author proposes a new method integrated with a logic algorithm supported by human gait detection sensors and head-shoulder detection sensors.This method can correctly judge type,location,speed and direction of the moving object in the passing channel.The principle of this method is to combine the information collected from sensors in gate and cameras over gate,makes different information to supplement and confirm mutually.In this way,the method provides logic of gait recognition without misjudgment and missing judgment,also it provides a brand-new idea for the existing logic of gate recognition and obtains good results in practice.
