Algorithm for evaluating fat and thin degree of foot shape

Abstract

The invention discloses an algorithm for evaluating the fat and thin degree of a foot shape. According to the technical key points, foot type data and foot type photos of a foot needing to be assessed in terms of fineness are obtained, the foot type photos are divided into two groups, and a foot meat state parameter = foot width data b - foot width data a; according to the foot meat state parameters, the foot meat states are divided into five types, and the foot meat states and the foot meat parameters are as follows: the medium hardness = 0, the hardness = 1-3, bone = 1-5, medium softening =-5, and the extra-soft degree is-15; the foot type is evaluated, the evaluation result is X, X = (foot width + foot meat parameter) / foot length, the result is displayed by percentage and is retained to an integer bit, and when X is 39%, the foot type is a standard; when X is less than 39%, the foot shape is thin; when X is greater than 39%, the foot shape is fertile; the instep height is evaluated, the evaluation result is Y, Y = instep height / foot length, and when Y = 22%, the instep height is the standard height; when Y is less than 22%, the instep is a low instep; when Y is greater than 22%, the instep is a high instep; and the foot shape is evaluated according to the X and the Y. According to the invention, the technical result is more accurate, so that the fitting degree of a finished shoe and a foot is improved.

Description

technical field [0001] The invention relates to the field of shoe shape adaptation, and more specifically relates to an algorithm for evaluating foot shape fatness and thinness. Background technique [0002] The evaluation of foot fatness and thinness is a scientific and rigorous project. The methods used by traditional craftsmen can only be applied to stores. When customers come to the store and ask for shoes, the master will take a piece of paper and let the customer step on the paper. Use a pen to trace the outline of the foot, mark the corresponding toes, and measure the circumference of each segment. But the master craftsman will "feel the flesh of the feet" and make shoes according to the softness and hardness of the flesh. Human feet are divided into: bone feet and fleshy feet, and fleshy feet are divided into hard flesh and soft flesh. The foot meat information obtained by touching the feet is very important to the suitability of the shoes. For example, for a stand...

AI Technical Summary

Problems solved by technology

The foot shape data measured by the current 3D three-dimensional scanning technology cannot obtain the hard and soft meat data of the feet, which makes the customized shoes and feet fit poorly

The bones of the human foot are approximately triangular. The footwear industry basically determines the fatness based on the circumference of the toes. Feet with a particularly high dorsal bone but a narrow sole have a low arch and a low instep. The toe circumference data of wide feet are the same, but they cannot wear the same shoes, so it is a flawed judgment method to determine the fatness and thinness based on the toe circumference data
