摘　　要：随着人们生活质量不断提高,汽车数量与日俱增,行车的安全变得越来越重要。根据现有的倒车雷达、视频监控等技术,提出了一种基于超声波测距的视频监控系统。采用HY-SRF05超声波测距模块,将各路距离信号传送给STC89C51单片机进行处理,再通过RS232串口将数据传输给凌动Atom D525主板,以实现最近距离的摄像头图像的自动切换。视频采集卡采用同三维T301系列,视频显示窗的自动切换由各路距离信号进行控制。With the improvement of people＇s life quality,the number of cars increases with each passing day the safe driving becomes even more important.With the existing reversing radar,video surveillance technologies etc.,a video surveillance system based on ultrasonic range measurement is proposed.With HY-SRF05 ultrasonic ranging module,various distance signals are transmitted to the microcontroller STC89C51 for processing.Through RS232 serial port,data is transferred to Atom D525 motherboard for implementing the automatical switch of distance image from the nearest video camera.With T301 series of video capture card,the video display window could be automatically switched by distance signals.

关 键 词：超声波测距 车载视频监控 视频切换
