| Abstract: | Utilizing the unit of Digitized Shape Editor and Freestyle in CATIA, Curve net map of feature lines and curved surface are created from the point clouds which is obtained with CCD Camera. Some technique and method are approached in the process from delimiting boundary till to fitting surface. The conclusion is discussed in the end through the error analysisfor the curved surface. |
