| 在末制导图像处理系统中,单模系统会带来匹配 精度不够、容易受干扰等问题,采 用多模系统进行融合决策,是提高跟踪定位精度和抗干扰能力的更优选择。本文基于多DSP 和FPGA,提出采用接口管理和图像匹配分开的分布式管理架构,设计实现了可兼容光学、 射频模式的多模复合末制导图像处理系统,系统具有高实时性、可重构性和通用性强的 特点。同时,在设计的系统平台上,采用适合各模式的FPGA预处理算法完成图像实时 预处理,采用SIFT特征匹配算法完成实时并行匹配运算。实验表明,本文设计的末制 导图像处理系统及SIFT特征匹配算法,在光学和射频模式下都达到了实时处理的要求；复合 末制导处理系统的匹配精度,要优于单模末制导图像处理系统的匹配精度。 |

| In a terminal-guiding image processing system,a single-mode image processing system will bring some problems,such as low matching precision and low anti-dis turbing ability.So a multi-mode image processing system is becoming a better choice.In this paper, based on multi-DSP chip and multi-FPGA chip,the distributed management hardware architecture system,which is composed of interface management and image matching computation,is proposed and used for realizing a multi-mode image pr ocessing system. This system is compatible with optical and RF modes.There are three advantages o f this system:high real-time performance,high reconfigurability,and high universal.Moreover,based on the compound terminal-guiding image processing system hardware platform in this paper,diffe rent FPGA pre-process algorithms are used for achieving image pre-processing under diffe rent modes,and then the SIFT feature matching algorithm is proposed for realizing image parallel matchin g computation. Experiments show that the compound terminal-guiding image processing system and SIFT matching algorithm in this paper can realize real-time processing under optical and RF m odes with high matching accuracy. |
