Abstract

The invention provides a three-dimensional foot model and shoe last model matching method based on position-based dynamics, and relates to the technical field of virtual trying on shoes. According tothe method, on the basis of three-dimensional grid models of feet and shoe lasts, a physical simulation algorithm based on position-based dynamics is utilized to simulate the final form and stress state of the feet wearing shoes. By means of the method, automatic foot and shoe last matching can be achieved, the deformation of the foot model accords with physical laws, and the final form and stressstate of the feet wearing shoes can be truly simulated; the method is high in running efficiency and high in stability.

Description

technical field [0001] The invention relates to the technical field of virtual shoe testing, in particular to a method for matching a three-dimensional foot model and a shoe last model based on position dynamics. Background technique [0002] At present, when people buy shoes on online shopping platforms, they are often based on the length and width of their feet, but human feet are complex three-dimensional shapes. Shoe size fit is often not guaranteed. [0003] The shoe last is an abstraction of the human foot. It is the mother of the shoe and the foundation and important mold of shoemaking. The key to whether a pair of shoes is comfortable to wear depends on whether the shoe last is suitable. Therefore, through the matching of the three-dimensional shoe last model and the foot model to simulate the final shape of the shoes worn by consumers, and then the force analysis of the matching results is carried out to obtain the evaluation of the fit, so as to help people choose...
