带摄像头和GPS的自行小车控制器设计

北京理工大学珠海学院2020届本科生毕业设计AbstractThis topic is at the heart of the car by single chipmicrocomputer control system,the system USES four infrareddetection head tracking and obstacle avoidance,use black tolight reflectivity in the tracking this characteristic,whenthe surface color is not black,in the reflectioncharacteristics of obstacle avoidance of obstacles to light,with an obstacle on the surface of the current,the infraredsensor to launch out by most reflected.The sensor outputs lowlevel 0 and lights up the lamp.At the same time,the ultrasonicprobe is used for ranging and obstacle avoidance.When thecontrol port emits a high level,it can wait for the high leveloutput at the receiving port,so as to calculate the distance.Keywords:smart car,Infrared obstacle avoidance,Black linetracking,Ultrasonic distance measurement and obstacleavoidance北京理工大学珠海学院2020届本科生毕业设计
