GPS与单片机实时控制线扫描摄像机的研究

Research on the Real-time Control of Line-scan Camera By GPS and Single-chip Microcomputer

采用GPS和单片机串行通信技术,设计了单片机控制算法,实现了对线扫描摄像机工作频率的实时的外触发控制工作方式的要求,着重论述了GPS和单片机的串口通信问题和单片机的程序控制问题.通过采用该控制系统进行的大量野外试验和对获得的车辆在高速行驶状态下实时拍摄连续图像效果进行的比较与分析,证明该部分设计较好的完成了路面检测系统要求的由外部信号触发实时控制线扫描摄像机工作的目的,从而获得了较为清晰的车辆在高速行驶状态下实时拍摄的连续图像.

The serial port communication technology of GPS and the single-chip microcomputer has been adopted, we designed the control algorithm of single-chip microcomputer, achieved the real-time requirement of the outside-trigger control mode-.of the frequency of the line-scan camera, emphatically discussed the question of the serial port communication of GPS and the single-chip microcomputer and the question of the procedure controlling of the single-chip microcomputer. Through a large amount of experiments using this system in the open country and by comparing and analyzing of the serial pictures which were pictured in the high-speed vehicle, it was proved that this system had achieved the requirement of real-time control of the line-scan camera of the road surface detection system, finally we obtained clear and＂ serial real-time pictures of the road surface in the high speed vehicle.
