The present invention relates to a method for calculating a camera parameter in a high-magnification by using the camera parameter obtained in a low-magnification. According to the present invention, the method for calculating the camera parameter which obtains a hand-eye matrix TC and CMk, and the focal length fk in a camera magnification of a ′k′ stage, obtains the focal length f1 and a location transform value tcz1 in a z-axis direction when the hand-eye matrix TC, CMk, and αf are the low-magnification, and obtains the focal length f2, and the location transform value tcz2 in the z-axis direction when having a magnification higher than the low-magnification. According to the present invention, a camera parameter value in the high-magnification can be calculated by using the camera parameter value in the low-magnification which can be precisely calculated, so the accuracy and stability are excellent. |
