A real-time image correlating speedometer based on FPGA parallel processing

研究制作了一种采用高速线阵CCD的实时相关速度计,其测量数据的输出速率可达每秒一万次。针对以往光学相关测速方法的问题进行了讨论,探讨了适合FPGA并行处理的算法,制作了高速线阵CCD摄像机及其处理装置。通过实验验证了系统的可行性和可实现性。

A real-time speedometer was proposed based on image processing using high speed linear CCD. It would output 10,000 velocity values every one second. That how the current method measure the velocity was discussed. The arithmetic fits for the FPGA parallel processing was proposed. Some experiments were taken which use the developed high speed linear CCD camera and the processing device. Experimental results indicate the system is feasible and realizable.
