A geometric camera calibration system includes an extrinsic iterative closest point (ICP) device that generates an estimated extrinsic matrix by adjusting an initial extrinsic matrix according to first 3D points in camera coordinates; and an intrinsic ICP device that receives 3D points in chessboard coordinates and accordingly generates an error metric between the 3D points in chessboard coordinates and predetermined second reference 3D points. The extrinsic ICP device performs ICP operation to minimize difference between the 3D points in camera coordinates and predetermined first reference 3D points. A current intrinsic matrix is then outputted as an updated intrinsic matrix if a current error metric is not greater than a previous error metric.
