For the 3 D measurements using the images taken with cameras, it is necessary to know the values of the camera's intrinsic parameters, such as the image coordinates of principal point, i.e., the projection of the projection center to the image plane, the principal distance between the principal point and the projection center, and the image distortion coefficients. In the 3 D measurements, we need to estimate the calibration accuracy of the camera's intrinsic parameters. Therefore, the authors examined a two-plane calibration method with respect to the calibration accuracy. Paying attention of the fact that the image coordinate measurement errors of the fiducial points propagate to the calibrated intrinsic parameter values, and the magnitude of the error could be formulized according to the setup of the fiducial points, the authors presented many useful relationships between the calibration accuracies and the fiducial point setups.
