| 摘 要： | Camera calibration is essential in computer vision. Theobjective of calibration is to endow computer vision sys-tem with the ability of accurate measurement by solvingthe camera parameters that characterize camera geome-try and pose.There are two different types of parameters, the in-trinsic and extrinsic parameters[1-3]. The intrinsic pa-rameters include the lens focal length f, lens distortionfactor k1, aspect distortion factor sx, the principal point(Cx, Cy), and scale factors (dx, dy) for… |
