摘　　要：本文采用证据理论进行三传感器的数据融合，开发了基于证据理论的三传感器数据融合算法，进行了软件仿真，研制出用于数据融合的高速红外图像采集和点目标处理系统，解决了红外点目标检测以及红外焦平面输出图像的高速传输、显示等难题．系统采用 ＰＣＩ总线作为数据传输的接口，大大提高了系统数据传输速率；采用带禁带的 Ｒｏｂｉｎｓｏｎ空间滤波器，完成在低信噪比条件下红外点目标的检测及其背景的抑制；并采用高速 ＤＳＰ器件对滤波算法进行实现，提高了目标的信噪比，保证了系统实时性的要求，具有功耗低、体积小、可靠性高等优点．A data fusion algorithm of three sensors based on Dempster-Shafer method is exploited and its computer simulation is implemented. The imaging system is developed in which high-speed image data are gathered from the sensors and point targets are detected. The main features of the system are: to transfer high-speed data using PCI bus as interface, to detect point targets in infrared image, to restrain background and noise using Robinson spatial filter with guard band, and to enhance SNR. Its volume is small and power is low. It is applicable to space and weapon system such as KKV and autonomous seeker.
