The accuracy of camera calibration by using combined with point and straight line method was compared with that of the point based method by performing camera calibration based on a pinhole camera model in the world coordinate system. Furthermore, the accuracy of the camera calibration by using the combined method was statistically evaluated in terms of the RMSE and the camera viewpoint using the simulation method described in the previous report. In camera calibration based of a pinhole camera model in the world coordinate system, the reproducibility of the camera viewpoint was good for both the point based method and combined method. And also, both methods had small variations in camera viewpoint relative to the RMSE. Even when the accuracy of the camera viewpoint relative to the RMSE in the point based simulation was poor, the combined simulation was able to reduce the error of the camera viewpoint relative to the RMSE.
