Fast image tracking system design based on TMS320C6455＋FPGA＋SDRAM

图像信息处理是一门涉及了数学、物理学、电子学、计算机、微电子学、自动控制、人工智能等多领域学科的综合技术，由于其多学科特性和技术挑战性，吸引了大批的科研人员对其进行研究和探索，大量的图像及信息处理技术的研究成果已广泛应用于国民经济各行各业，发挥着越来越大的作用。

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 realtime tracked and displayed.In order to meet the requirements of real-time tracking for 100frame/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.
