Xican Institute of Micro-electronics Technology,Xican,710075, China) Abstract :A new method based on the correlation of sub-image and affine transformation is presented in order to realize the registration of infrared image and visual image.It has improved traditional image registration method based on the edge correla- tion of images.In the method, firstly, croping image manually and getting the sub-image from the reference image and image prepared for registration. The sub-image contains the same target of the scene.Secondly, extracting the edges of sub-image by Canny operator, and calculating parameters of affine transformation model between sub-images by edge correlation. Thirdly, further amending the parameters to get affine transformation model between original images,and carrying out affine transfor- mation and bilinear interpolation in the image prepared for registration to realize image registration.The results pro
