摘要

An algorithm is presented based on curvature variance to calibrate the lens distortion of digital camera. At first, straight lines are extracted in the image while the actual line is slightly curved due to lens distortion. Therefore lines extracted are dimidiated and each line section is extracted again to detect the curvature caused by lens distortion. Then the curvature is used to calibrate lens distortion. It is proven by experiments that this algorithm comes out with satisfying result.
