Image mosaicing is a hot spot of medical image processing technology in recent years,and has broad value of the research in ophthalmology.This paper proposed a fundus image mosaic method based on template matching according to the characteristics of fundus images.First,grab a pair of initial matching points in the overlapping area of two images,use these points as the center to get different size of template region and search region respectively,then fix the optimum matching points according to the template matching method.And then adjust the images through translation and rotation.At last eliminate edge joint by linear transition of overlapping regional to achieve a smooth transition between images.After experimental verification,fundus images of different perspectives were matched by this method which also has quick calculation speed and high accuracy.
