An image mosaicing new approach based on the integration of image matching and adjustment

which can effectively remove the residual geometric distortions between mosaiced images

was presented. At first

selecting one of mosaiced image as the reference

for example

the left side image

then the other image was matched with it in the overlapping area. A point feature-based matching algorithm was employed

and a quadratic polynomial fitting method was used to locate the corresponding points within one pixel. On the basis of these corresponding points

a adjustment algorithm was performed by adding a polynomial increment to every pixel position in the right side image so that geometric position distortions between the two images is minimal under Least Square principle

thus the two images could be mosaiced together seamlessly. At the same time

the usually used methods for radiometric difference reduction are presented .The proposed approach was applied to mosaic two rectified aerial photos

after image adjustment

the residual geometric distortion was greatly removed.
