摘要
为了满足红外跟踪系统中对预处理越来越高的实时性要求,本文提出了一种基于现场可编程逻辑门阵列(FPGA)的中值滤波器。文中首先分析了当今FPGA发展的特点和优势;并对设计所用的FPGA芯片XC2V1000的结构特点进行研究;具体讨论了中值滤波在FPGA中的实现。结果证明方案可行,滤波具有良好的实时效果。
In IR tracking system, image preprocessing must run at a special high-speed. The article present a median filter designed with Filed Programmable Gate Arrays （FPGA）. Firstly, The article discusses FPGAts characteristics and advantage over DSP or discrete components. Secondly, the structure of XC2V1000, which is a kind of Xilinx＇s FPGA, is given. Lastly, the theoretical analysis of the median filter and the recourse used in FPGA are presented. The results prove that the design of the median filter is successful. And a significant result of running speed is achieved.
