摘要

图像跟踪是图像处理领域研究较多也比较关键的技术之一。随着微电子技术不断发展，在光电经纬仪、机载光电平台等图像跟踪应用领域对视频跟踪器系统的要求越来越高，当前视频图像帧频偏低已对伺服系统传输带宽形成不小制约，而高帧频图像又有视频传输的瓶颈。为了解决这一问题，本文设计了一款基于TMS320C6455+FPGA+SDRAM的图像跟踪系统。本系统通过FPGA控制SDRAM对视频图像进行缓存后输出，达到视频降频输出的要求，以解决高帧频图像数据量大难以实时传输显示的问题，同时通过对相关跟踪算法做进一步优化使其满足100 frame/s视频的实时跟踪要求。实验证明该系统工作有效稳定，能满足工程实际需求。

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.
