Abstract: In recent years, the image fusion technology already has become one of key technologies in some areas, such as computer vision, automatic control, robot, target identification and track. Its main research object is the registered multiple source image having the same field of view(FOV). There exist a lot of image systems with different features in different fields of view in real life. The multi-source image fusion technology for different fields of view can improve the performance of image acquisition system without investment increase in hardware. For the multi-image fusion technology of different FOV, in this paper, a registration method is proposed, which combines affine transformation and linear interpolation, the images before and after fusion are analyzed and compared in temporal and spatial domains and the results are evaluated to verify the feasibility of the method.

Key words: information processing, multi-source image, different field of view, registration, fusion
