Personality shoe last model generating method for integrating three-dimension foot-shaped global parameter and local cross section regulation

Abstract

The invention discloses a comprehensive foot profile three-dimensional individualized shoe tree model generation method for adjusting global parameter and local cross section. The method is taken in the following steps: 1, a three-dimensional standard shoe tree model and a user foot profile model are read in; 2, the foot profile parameter of the read-in foot profile model in the step 1 is measured and the shoe tree model parameter is calculated according to the foot profile parameter, then the shoe tree model is deformed under the drive of the shoe tree model parameter; 3, position control points are respectively defined for the foot profile model and the shoe tree model formed in the step 2; 4, the foot profile model is aligned with the shoe tree model in accordance with a match position reference point; 5, the section of the key position of the foot profile model is defined; 6, the section got in the step 5 and deform the shoe tree model is analyzed on the basis of the section; 7, the three-dimensional shoe tree model designed well is output. Based on the thought of stepwise refinement, the invention generates the individualized shoe tree model with high matching level according to the foot profile of the user and changes the actuality of rough classification and less comfort in the traditional shoe tree generation method.

Description

technical field [0001] The invention relates to a method for generating a three-dimensional shoe last model, in particular to a method for generating a personalized shoe last model that integrates global parameters of a three-dimensional foot shape and local cross-section adjustments. Background technique [0002] As far as the generation of shoe last data is concerned, the traditional last-making method is based on the code length specified by the national standard, and is divided into wide-foot type and narrow-foot type, and large-scale mass production is carried out with a large-scale last carving machine. There are many deficiencies in it: [0003] 1) The matching degree of the last is rough. Due to the small number of last-making parameters, it is simply to add a size for every 5mm of the foot length, plus the classification of width and narrowness, while human feet have great individual differences, which leads to the fact that the shoe last cannot be carefully matche...

Problems solved by technology

Therefore, whether the size of the plantar circumference of the shoe last and the physical arrangement are reasonable will not only affect the wearing comfort, but also cause early damage to the sole of the shoe, and in severe cases, the skin on the sole of the foot will be worn
