基于TMS320C6455的目标跟踪系统设计与实现

Design and implementation of target tracking tystem based on TMS320C6455

介绍了一种基于高速处理芯片TMS320C6455和FPGA架构的目标跟踪系统。该系统以DSP与FPGA为主体设计一套图像处理设备,利用局域熵算法来实现简单背景下小目标的跟踪。FPGA采用Xilinx公司生产的XC5VSX95T,用来对原始图像数据进行预处理。DSP芯片采用TI公司生产的TMS320C6455,通过局域熵算法对预处理后的图像进行实时跟踪并且将目标信息返回FPGA。FPGA获得跟踪结果后,将目标信息与原图像叠加,通过显示器将图像结果进行显示。局域熵算法经过优化后,目标检测跟踪时间大大缩短,满足硬件系统实时性的要求。

T his paper introduces a kind of target tracking system based on high speed processing chip TM S320C6455 and FPGA .The system utilizes DSP and FPGA as the main body to design a set of image processing equipment ,and the local entropy algorithm is used to implement a small target tracking under the simple background .The FPGA use Xilinx Com‐pany’ s XC5VSX95T designed for the original image data preprocessing . DSP chip produced by TI company ’ s TMS320C6455 ,we will use local entropy algorithm to detect the preprocessed image and then return the target informa‐tion to the FPGA .After the FPGA gets the tracking results ,it overlays the target information to original image and dis‐play .After the local entropy algorithm is optimized ,target detection tracking time shortens a lot ,meets the require‐ments of real‐time hardware system .
