基于CCD镜头的公交车无人驾驶停车系统

Driverless Parking System for Bus Based on CCD Lens

针对公交车司机因突发因素导致公交车失控的情况,研究了基于CCD镜头的公交车无人驾驶停车系统,用于实现公交车的自动安全停靠。该系统通过驾驶室紧急按钮一键启动,运用CCD镜头采集交通环境信息,借助超声传感器测量障碍物距离,通过PID算法控制公交车自动驾驶至安全位置开启车门,大大提升了公交车的安全性能。

Aiming at bus out of control which is resulted by bus driver because of unpredictable factors,driverless parking system for bus based on CCD lens is studied and is used for parking automatically and safely.This system is initiated by start stop engine located in cab.The CCD lens is utilized to sample traffic environment information and the ultrasound sensor is employed to measure distance from bus to barrier.Then PID algorithm is performed to control bus to drive to safe location automatically and open the gate,which can remarkably improve the safety performance of bus.
