The authors propose a practical camera calibration system on mobile platforms to calibrate the camera's intrinsic parameters, based on the geometrical property of the vanishing points, which are determined by two perpendicular groups of parallel lines. In this system, first, they detect and cluster the lines of the input images to compute the vanishing points. Then, they establish the intrinsic parameter constraint equations based on the perpendicular property of the vectors that connect the optical center and the vanishing points and solve them using the least squares method.
