A Fast Geometric Deformation Method to Adapt a Foot to a Platform
The main goal of this research work is to develop a new system that designs shoes that adapts exactly to the foot shape. This research is based on a biomechanical anatomical structure of the foot and of the deformable shape. The system automatically selects significant foot points. We consider several anthropometrical parts of the foot in order to apply a global deformation with different axis. Also an interpolation process is designed to combine the several parts of the foot in an efficient and accurate manner. We consider different criteria in the deformation process because the top is rigid and the sole is assumed non-rigid. The system is implemented in an optimized software version in order to control the computational cost of the deformation process. A prototype of oriented commercial Application Programming Interface (API) is developed for non specialized users of the system. The results presented evaluate the error between deformations and we validate the error of several users (foot and last). Also the low error obtained guarantees the comfort of the foot that is a very important objective in this area of research.
