Shape completion and modeling of 3D foot shape while walking

We developed a technology for creating homologous models of foot shape data obtained from a 4D measurement system. Homologous models consist of the same number of the same topology, and each data point in the model is defined based on the anatomical homology. In the present modeling technology, we use a homologous model using a polyhedral template. By fitting the homologous foot model to data obtained from 4D measurement system, our approach can accomplish homologous modeling for 4D-measured data. We show how the model can be used for shape completion and modeling -generating a complete surface mesh and granting anatomical feature points given a limited set of captured points specifying the target shape. Using principal component analysis (PCA) and posture change, we accomplish homologous modeling for 4D-measured data of human foot shape.
