摘要
为帮助驾驶员及时知晓车辆倒车后方环境,设计了一种基于STM32的障碍物定位检测系统.该系统通过两组超声波传感器分区对障碍物的距离及方位进行检测,根据多路传感器信息的融合得到障碍物的方位信息并进行显示,并按照所划分的3种危险等级的警示音报警.实验结果表明测量误差小,测距准确,满足目前市场需要.
In order to acquire vehicle rear environment timely, a kind of ultrasonic warning system is designed based on STM32. The obstacles of distance and azimuth is detected with 2 groups of ultrasonic sensors according to the sender and the receiver points area detection, and the position and azimuth of obstacles of multiple sensor information fusion is displayed with accurate sound and light alarm according to the division of three alarm levels. The experimental result shows the measurement with less error, high precision and sensitivity to meet the actual needs of the market at present.
