摘要：Based on colour images acquired from unmanned planes, we use projective transformation formula to eliminate the perspective distortion observed in overlapping area in two images and get big frame mosaic images through the arithmetic which is based on triangulated irregular network and improved SZELISKI. Confirming overlapping image areas are determined through computer graphics. TIN method is applied to image registering and mosaicing. SZELISKI mosaic algorithm is improved in this paper to control the scope of mosaic area, which is more favourable to human vision. Through researches on the above techniques, original images that acquired from unmanned planes can be processed sequentially by the method of image rectification, image registration, and image mosaic to get large frame images rapidly.
