The position with the smallest error value is used as the best measurement position, and the photo closest to the ideal angle can be obtained. The numerical value of the error is represented by the roundness of the inner hole diameter Ød calculated by the first area scan camera 511 , the greater the roundness, the smaller the error, and vice versa, the greater the error.
