Method for designing shoe tree according to pelma image analysis data

Abstract

The invention relates to a method for designing a shoe tree according to pelma image analysis data. The method comprises the steps of pelma image collection, footprint analysis, data extraction, shoe tree ground pattern design and shoe tree design, i.e., utilizing a pelma scanning system; measuring foot characteristic size and characteristic lines through a footprint analyzing module in the footprint analysis step, and carrying out location analysis and relative size measurement on the size of the pelma stressed position to generate corresponding data; extracting the measured, analyzed and calculated size data of the foot pattern characteristic position and the size of the pelma stressed position, and inputting the size data and the size into a database; carrying out statistics and calculation on the comprehensive maximum, minimum and average, and comparing with empirical values according to the statistical and calculated data to obtain the ground data of the shoe tree; designing the ground pattern of the shoe tree according to the obtained ground data of the shoe tree; determining the ground data of the shoe tree; and completing the design and the manufacture of the shoe tree. The invention provides a precise, simple, convenient and feasible shoe tree designing method for shoe tree manufacturing and shoemaking enterprises.

Description

technical field [0001] The invention relates to a method for designing a shoe last according to the analysis data of a plantar image, which is applied to the industries of shoemaking and last making. Background technique [0002] Shoe last is the model of shoemaking, its size and shape are related to the internal space of shoes. With the development of social economy, consumers pay more attention to the comfort and fit of shoes, and personalized customization has become a fashion. There are also many related researches in this field in our country. One is the traditional purely manual operation, using micrometers, vernier calipers, cloth tape rulers, etc. to measure the foot shape, but it requires experienced personnel to operate, and human factors interfere too much. One is the use of three-dimensional foot shape scanning measurement. Although it feels very modern, the three-dimensional measuring device cannot be accurately used for the design and development of shoe last...

Problems solved by technology

One is the use of three-dimensional foot shape scanning measurement. Although it feels very modern, the three-dimensional measuring device cannot be accurately used for the design and development of shoe lasts due to the lack of an accurate positioning system. As a result, the designed shoe last still depends on the designer. Personal feeling to judge whether it is suitable, also lacks scientific and standard size control, and the cost is high, so it is difficult to apply in the market
