Fast image tracking system design based on TMS 320C6455+FPGA+SDRAM
and it has been one of the key technologies of the image processing. With the continuous development of microelectronics technology
it requires more and more for video tracking system in practice
such as theodolite and optical platform of UAV. The current video frame rate of the image tracking system is too low
it has formed large constraints on transmission bandwidth of the servo system. While
there are bottlenecks on transmission using high frame rate. In order to solve the above problems
this paper designed a image tracking system based on TMS320+FPGA+SDRAM. In this system
the data of image output are send out after SDRAM controlled by FPGA cached
so that the video frame rate becomes low
and it can be real-time tracked and displayed. In order to meet the requirements of real-time tracking for 100 frame/s video
this paper make the correlation algorithm further simplified. Experimental results show that this system can work effectively and stably
and it can meet the actual needs of the project.
