Image matching machine is an important part of target recognition system. The scheme using TMS320C6415 as the core processor to realize an image matching system is put forward in this paper.SDRAM storing real-time pictures,preassembled and preset data,temporary data and program code, FLASH ROM solidified with code,preassembled and preset data, and dual port RAM realizing communication with superior control equipment are adopted in this project.Implementing image matching algorithm with software, image matching system with DSP is more flexible. TMS320C6415 is one of the most advanced DSPs in the world, and it has a processing ability of 5760 MIPS.Experiments show that this system is able to match two pictures of 512×512 within 0.02 s with PTT correlation algorithm or a picture of 72×72 and another picture of 320×320 within 0.1 s with product correlation algorithm. This system is featured by compact construction,high reliability,and good real-time ability.The system provides a new high-speed processing platform for an image matching system.
