This paper presents a more accurate and faster method for sub-pixel TDICCD image registration. The method makes the best of the overlapping pixels between multi-channel images, which allows for scaling, translation and rotation. Secondly, the proposed technique combines an efficient pixel-moving interpolation scheme with surface fitting, which makes use of accurate interpolation calculation and fast surface fitting in the iterative process. Finally, the accuracy and speed of the algorithm is evaluated by sub-pixel registration of multi-channel images and comparison with other sorts of efficient methods. The experiment results show that the accuracy of the method reaches 0.01 pixels and it is 3 times faster than the interpolation method.
