| Abstract: | Based on the principle of least-squares method, it derives the formula of the coordinate of the circle center and evaluates its accuracy. Then the correctness of the coordinate of the circle center is verified by the real measurement of circle center. Meanwhile, using the matlab programming language, the coordinate of the circle center fitting calculation program is implemented, which can be used in manufacturing and installation of large mechanical equipment. |
