| Summary: | 碩士 === 國立中興大學 === 機械工程學系 === 91 === This paper describes a method of patching contours, to prove the contours range when measuring a 3D curved surface. The optical measurement method is Shadow Moire. By using five steps phase shift to get the phase distribution of an image, and matching up the aligned phase shift, then we can receive the image contours.
Fixing the optical equipments and then using the Coordinate Measuring Machine to move the object which is measured during the process of the experiment. After that, we get every part of the contours, and use the least square method to search the minimum error of total patching.
