摘　　要：融合方法的理论研究较多,而通用的实时图像融合系统较少。本文给出了具有VME总线、并行分布式结构的系统方案,核心是基于标准总线的实时系统,DSP并行完成多源图像实时配准和融合,FPGA实现总线和视频同步控制。所实现的系统具有运算能力强、通信带宽大、可扩展性和通用性强的特点,实用表明了它的可行性。The existing researches of image fusion most focus on theory. The universal and real time fusion system is presented rarely. A general purpose scheme of real time image registration and fusion system based on VME bus and parallel computer architecture is given. The kernel component is real time operation system of standard bus. DSP is served as the CPU to perform registration and fusion parallel. FPGA is designed to control VME bus and video synchronization. The architecture has characteristics of strong computational capability, broad I/O bandwidth, and expansibility. The result of experiments indicate that this system works perfectly.
