Research of double-Matrix CCD-Based Speed Monitoring System

针对交通工程中的测速要求,提出了一种基于双面阵CCD实现测量运动物体速度的方案,设计了测速系统的硬件平台,提出使用计算机控制两个面阵CCD对运动物体进行了动态图像检测、信号分析以及速度计算,并利用图像差分算法作为计时触发信号,提高了测速精度。通过对实验结果的分析证明文章所提出的方法行之有效。

According to the demand of Speed Monitoring in traffic system, a method based on double-Matrix CCD is introduced in this paper. We designed the hardware of the system, and suggest use computer control the CCD to capture the motion picture, analyse the signal, and calculate the speed of motional subject.We use difference- arithmetic as timing- trigger, improve the precision of the system. The results of experiment shows the method is effective.
