Abstract
A novel calibration method of camera with variable focal length is proposed.By means of using the orthogonal rotation matrix and constraints among camera parameters in the single-view vision
a new algorithm to linearly and exactly calibrate the camera from single-view at least six known feature points is developed.Both simulation and true image experiments prove the feasibility and robustness of this algorithm.
