Abstract
LECAD research group contributed to software development for three-dimensional laser scanner for foot and shoe last scanning. Industrial partner ALPINA obtained a considerable measurement data of shoe lasts, where the surface was described by a cloud of spatial points. The data about shape and characteristic dimensions need further be processed to become usefull for shoe manufacturer or reseller. We intend to develop methods for processing the acquired data, which will be able to extract characteristic anatomic properties and dimensions (length, width and height of intersecions, etc.). The standard procedure to manufacture the shoe lasts is to use the 3D computer model, prepared by a comercial modeller. We therefore intend to convert characteristic dimensions into NURBS parametric surface model , consisting of small number of surface patches. We will develop a data model, which will link the NURBS surface patches to characteristic dimensions of the shoe last. The dimensional parameter changes will automatically affect the surface model. The approprietness of the conversion model will be tested by comparing the surface disagreement on original triangulated surface. We will investigate the methods for global functional deformations of NURBS model (shoes with high heels) as well as the methods for local deformations (smoothing). We will consider the adding of surfaces to the model (technological and fashion requirements).
To be able to use NURBS surface model in commercial 3D modellers, we will develop a converter of data into standard IGES 5.0 format. The transformed data can then be used in shoe last preparation. All procedures will be coded in standard programming languages C and Cplus plus. We will develop the interactive 3D graphical viewer to test and demonstrate the use of algorithms. The software will be compatible with existing equipment of the industrial partner.
