METHOD AND APPARATUS FOR DETECTING DISPLACEMENT WITH SUB-PIXEL ACCURACY |
摘要 |
A method of detecting displacement with sub-pixel accuracy includes the steps of: capturing a first array image and a second array image; interpolating the first array image to form a reference image; interpolating the second array image to form a comparison image; comparing the reference image with the comparison image so as to obtain a displacement. The present invention also provides an apparatus for detecting displacement with sub-pixel accuracy.
