| Abstract: | This paper presents an approach on calibration of camera via boundary extraction and geometric invariance. First, a threshold-based algorithm is applied to extract the boundary of the photo. Second~ several geometric invaxiances axe introduced in several propositions. Then abundant mappings can be determined. Finally, a nonlinear program is proposed to determine the camera system. The accuracy and efficiency of our method are shown in several numerical experiments. |
