摘　　要：针对路权分配不合理导致的行人闯红灯所引起的人车矛盾问题,提出基于STM32和Raspberry Pi的智能交通灯控制系统。选用摄像头采集行人数量和近交叉口车流数量,STM32控制舵机根据需要旋转摄像头角度,实现多角度信息采集,采用OpenCV进行图像处理、Raspberry Pi实时控制,应用智能算法进行控制,并对恶劣天气下的算法进行优化,达到路权智能实时分配的效果。In order to solve the contradiction between pedestrian and vehicle caused by pedestrians＇ red light because of unreasonable distribution of road rights,an intelligent traffic light control system based on STM32 microcontroller and Raspberry Pi is proposed.The number of pedestrians and the number of traffic near the intersection are collected by the camera.The STM32 controls the servo rotates the camera angle according to the need to achieve multi-angle information collection,which adopts OpenCV for the image processing.The Raspberry Pi is used to realize the real-time control,it applies the intelligent algorithm for control,and optimizes the algorithm in inclement weather.Finally,the system is optimized to achieve the real-time distribution of road rights.
