A fast image mosaic method is proposed for an aerial reconnaissance CCD camera.In this method,parameters of affine transformation were first evaluated by using the work parameters of the camera,which can supply a rough registration area of images.Then,the image cross-correlation was employed to obtain a higher precision in the affine transformation parameters by searching this rough area.Finally,a bilinear interpolation method was used to fuse the overlapping area of images.Experimental results of this meth...
