英文摘要：

In order to solve the problem of rotated and scaled scene matching in the hardware platform of real-time implementation, software and hardware design were presented for the real-time scene matching system. The traditional Fourier-Mellin transform （FMT） had been improved to suit the hardware platform, and reduce the influence of details information on the calculation results. On the other hand, using DSP TMS320C6416 processor as the core, which possessed the property of high processing speed and a large on-chip memory, it also provided a set of high efficient manual optimization functions commonly used in signal processing applications, such as filtering and FFF, it made the involved complex algorithms realize on the hardware real-time. Experimental results show that DSP TMS320C6416 based real-time scene matching processing can be realized, the processing time is less than 40 ms and the rotation measurement accuracy meets the requirement.
