| 摘 要： | 设计了一种视频跟踪器,它以高性能DSP芯片TMs320Vc5416作为中央处理器,结合现场可编程门阵列(FPGA)构成外围电路逻辑控制,搭建了硬件跟踪平台,并在此系统中实现了用Kalman滤波估计目标位置和Mean Shift算法跟踪的目标位置自适应加权求和,作为目标最终跟踪结果的跟踪算法,有效减少了相同颜色背景的干扰.实验结果表明,本系统具有良好的跟踪性能,满足实时性要求.

| Abstract: | The designed video tracker takes TMS320VC5416 as the center processing chip, and realizes the logic control of periphery circuit based on FPGA. The self-adopted weighted sum of the target locations estimated by Kalman filter algorithm and tracked by Mean Shift is used to obtain the final tracking results. And this new algorithm could effectively reduce the background interference with same color. The experimental results show that this system could track targets well and meet the real-time requirements. |
