In calibration procedure  sub-pixel center extraction is the crucial step for the final accuracy. In this paper  a new sub-pixel extraction method is proposed. Edge detection at pixel level is obtained using LOG operator  then sub-pixel edge detection is realized using the Facet model. Finally  the least squares ellipse fitting is operated on the sub-pixel edge to determine the sub-pixel center. Experiment on a series of simulated images indicates that this algorithm is able to realize the center location accuracy of 0.01-0.02 pixel  and meets the requirement of sub-pixel level.
