To make customised sports shoes, a customized shoe last expert system is established based on the light sectioning method for 3D profile measurement. A least square fitting method is proposed to approximate the scanned cloud data, to establish the parameterized standard shoe last database in form of NURBS curves. A foot shape subsectioning method based on the shape feature points is used to establish the segmental empirical repository of shoe last conformability by using the generative formula. The expert system is therefore formed with the standard shoe last database and the segmental empirical repository. With the expert system, special shoe last is customizod, and the system can spread to other kinds of shoes.
