中文摘要：

针对传统红外侦察方法存在的不足，为综合紫外、红外和可见光的成像优点，系统采用DSP为处理核心，构建一种小型实时多源图像融合系统，通过光机结构设计，经过倍率调整和数字位移，以及一系列试验进行多光谱的融合。实验结果表明，系统设计合理，能够完成多源图像的融合。该系统具有体积小、重量轻、功耗低、处理速度快和工作模式灵活可选等特点，非常适合载荷能力有限、需执行多样化任务的无人机搭载应用。

英文摘要：

In view of the traditional infrared reconnaissance method existence insufficiency, integrated ultraviolet, infrared and visible light imaging advantages, system uses DSP as the processing core, build a small real-time image fusion system, through the optical structure design, after the rate adjustment and digital displacement, and a series of experiments are conducted to multispectral fusion. The experimental results show that the system design is reasonable, able to complete the multi-source image fusion. The system has these advantages of small volume, light weight, low power consumption, fast processing speed and working modes of optional features, very suitable for the loading ability is limited, to perform various tasks of UAV flight application.
