Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose a new calibration method for oblique-viewing endoscopic camera with a strong distortion for arthroscopic surgery support system by augmented reality system. As traditional research, there are the calibration methods for oblique-viewing endoscope without a distortion or the methods for the non-oblique-viewing camera with a distortion, but the techniques accurate enough to compensate for both of them contain, as far as I know does not exist. In this study, seeking to add new methods required precise parameters of the existing methods, validation experiments were accurate. As a result, the proposed method obtained higher accuracy than the conventional method. So think of this proposed approach is useful in calibration for oblique-viewing endoscope with a strong distortion.
