多源图像实时配准融合系统

多源图像配准融合方法的理论研究较多,已有的融合系统往往针对特定应用通用性差,并且不具备实时性,而具有并行分布式计算机体系结构的通用实时图像融合系统有望解决这一问题。该系统的核心是基于标准总线上实时操作系统,以ADSP并行完成多源图像实时配准和融合,CPLD实现总线和视频同步控制。具有运算能力强、I/O带宽大、可扩展性和通用性强的特点,并以此构成了高速实时融合系统。实用表明此方案是可行的。

Real-time multisensor image registration and fusion system

The existing researches of image fusion are mostly focused on theory. The universality of conventional fusion system which has no real time is highly limited because it is often designed for a special purpose. A general-purpose real-time image registration and fusion system based on parallel computer architecture may be a hopeful solution. Its kernel component is real-time operating system of standard bus. TS101 DSP serves as the CPU to perform parallel registration and fusion. CPLD is designed to control VME bus and video synchronization. The architecture has characteristics of strong computational capability, broad I/O bandwidth and expansibility. The results of experiments indicate that this system works perfectly.
