基于 TMS320C6455＋FPGA＋SDRAM的快速视频跟踪系统设计
Fast image tracking system design based on TMS320C6455+FPGA+SDRAM
摘要
Abstract
Image tracking is focused by many researchers,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.关键词
