| Abstract: | This paper introduces the theory and method for close-range-photogrammetry and computer-aided-designing sport shoes, which can be adapted to get a sample of three dimensional coordinates from the surface of sport shoe tree. It deals with the method about how to get the three dimensional model of smooth curved shoe irers surface by double-cubic-B-spline fitting. The designed drawing of curved shoe surface is flattened out by accurate mathematic ways. On the basis of developing the Auto CAD Drawing Software fully, we have made a series of software system, which can be used to design variotts sport shoes with Auto Lisp Language. The system is in reality for us to design sport shoes with the computer. |
