show that the root mean square errors for coordinates and poses are 0.352 mm and 0.0145 rad at field of view of 690 mm×520 mm, respectively. Unlike the traditional edge extraction algorithm, the proposed algorithm is robust with respect to defective data and noisy data and can obtain precise localization for valve center at a wide field of view.
