Design On The System Of Video Image Target Identification And Processing Based On DSP

This system researched and designed by this paper is a part of a Anti-Tank Guided Missile guidance system. In order to detect and recognise the target and the missile, we design the video image target identification and processing system.This paper has analyzed the function demands of this system, has given the hardware's design proposal of this system, the hardware mainly consists by DSP, FPGA and MCU, and the main ICs are connected by I~2C bus, TI Corporation's TMS320DM642 DSP IC chip is used as the core processor of the system; Also has given the software's design proposal, has chosen and designed the algorithm and the method for the purpose of detect and recognize the target, particularly improve the frame difference method and realize it, which is one of method for detect movement target in the ground, and has used characteristic scalar which defined by ourselves.Finally, we have examined the system both indoor test and outdoor test, and the result shows that the video acquisition, video image extract, data analysis and data processing can be done by the system, and almost achieve expectant requirements of technology.
