摘要
介绍了激光雷达测距原理,进而引入到测距系统中,构建了一车载测距预警系统,分析了系统核心模块的组成和基本原理并给出了程序框图。当车间距达到阈值时及时发出声光与语音信号,提醒司机注意,避免追尾事故的发生。
Study on a Detecting Radar System, Then a warning system, which is used to survey the relative velocity and distance is constructed, and the important sections of the system are studied and simulated. This system can be used in night and other bad circumstance to survey the car ahead and give out the alarm when the relative distance reach the limit , which can be used to avoid the traffic accident.
