摘要

随着我国武器研制水平的不断提高，高速度、高机动能力的武器装备越来越多，为了使型号武器中的目标跟踪器对于目标大尺度变化、速度快等情况有很好的鲁棒性，本文设计了一款基于DSP+FPGA的实时目标跟踪系统。针对均值漂移算法不适用于快速运动目标等限制情况使用多级金字塔进行了改进，采用背景加权的核直方图建立目标模板从而减小跟踪框中背景对于跟踪的影响，并将整个算法进行了优化以在嵌入式系统上实时实现。实验结果表明，本文设计的实时目标跟踪系统对于目标的快速运动、尺度变化以及一定程度的模糊均有很好的跟踪结果。每帧的平均处理时间为13.5 ms，满足实际工程的实时性和稳定性要求。

Abstract

Along with the weapon research development

more and more weaponry with high speed and high mobility are equipped in our country. In order to make target tracker of the weapons have good robustness under the situation of the target scale changed and high speed

a real-time target tracking system based on DSP+FPGA was designed. The MeanShift Algorithm was improved by using multi-level pyramid and the background weighted kernel histogram

which can reduce the influence of background in the tracking box

then the whole algorithm was optimized to implement on the embedded system in real time. The experimental results show that the design of the real-time target tracking system is robust for the rapid motion of the target

scale changing

and some degree of fuzzy. The average processing time per frame was 13.5 ms

which can meet the engineering requirements of real-time and stability.
