Problems solved by technology

A pair of shoe lasts with high comfort usually needs to be tried and modified by the wearer for many times, and the feedback information of the tryers is all subjective, without objective data as a guide. It is laborious, and the bottom curve of the shoe last is difficult to make most people feel comfortable, which limits the development of the shoe last production industry

Embodiment Construction

[0023] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0024] 1. Acquisition of three-dimensional data of the foot:

[0025] Such as figure 1 As shown, before the 3D scanning of the foot, use the marker points to attach to the following key parts of the foot: the first metatarsophalangeal, the fifth metatarsophalangeal, the fifth metatarsal tuberosity, and the heel process; The 3D model of the foot is collected by a 3D scanner at different heights and the heel pad is raised, and is saved at a ratio of 1:1. figure 1 The upper part of the middle is the foot 1, the middle is the shoe last 2, and the bottom includes the footprint 3 and the bottom of the shoe last 4.

[0026] 2. Three-dimensional foot shape analysis:

[0027] Such as figure 1 As shown, input the above three-dimensional foot shape data model into the software, and first mark the following key points of the foot: the first metatarsopha...

Abstract

The invention discloses a method of designing bottom arcs of a shoe last, which includes acquiring foot type bottom arc curves and designing a shoe last board. Acquisition of foot type bottom arc curves includes acquiring three-dimensional data of a foot, calibrating points of all parts of the foot, acquiring an axial profile diagram about the foot, and acquiring bottom arc curves of the foot type. Design of the shoe last board includes setting up a referential shoe last bottom arc board, designing step by step according to the foot type bottom arc curves, smoothly connecting all the curves and obtaining the shoe last bottom arc board. Three-dimensional foot scanning for acquiring a three-dimensional foot mode replaces manual measurement of foot dimensional data, accuracy of data acquisition and analysis is guaranteed, and subjective comfort evaluation by a tester is utilized, so that the best comfort of the shoe last made by the method can be achieved. Application of the method promotes the shoe last industry towards high precision, high comfort and high efficiency.

Description

technical field [0001] The invention relates to a design method of the bottom arc of a shoe last, in particular to a design method of a bottom arc of a shoe last which is fully digitally operated based on the bottom arc of a foot shape, and belongs to the field of shoe last production. Background technique [0002] Shoe last design is the primary task of shoemaking, and it is designed based on the data of various parts of the foot shape. Therefore, the quality of shoe last design directly affects the comfort of finished shoes. The most important thing in shoe last design is the design of shoe last bottom arc, which is one of the most important factors to determine the comfort of shoe last part. [0003] In the design of the bottom arc of the traditional shoe last, the data of each part is based on the empirical value in practice as a reference. After the design of the entire shoe last is completed, the subjective comfort feeling is put forward through the try-on with a sta...
