Problems solved by technology

The main feature of this design method is that the shape is fast and convenient, but when it comes to the overall modification of the shoe last, it often needs to import a new standard last for design, and also requires the user to have the conditions to use the 3D scanning equipment

Embodiment Construction

[0029] From the perspective of personalized leather shoes customization, the present invention realizes a rapid design process of leather shoes that meets customer requirements, and its technical route is as follows: figure 1 As shown, the specific implementation steps are as follows:

[0030] 1. The shoe last modeling method based on the key dimensions of the foot first needs to obtain the key dimensions of the user’s feet, draw some basic control points based on the center line according to the key dimensions of the foot, and establish the original shoe last through these basic control points Base sample contour curve; By establishing the knowledge base of different head shapes standard shoe last bottom samples, according to the last shape selected by the user, further contour control point interpolation is performed on the original shoe last bottom sample contour curve to obtain the final (such as figure 2 ); According to the key size data of the foot, the basic control po...

Abstract

The invention discloses an interactive shoe last modeling method based on foot feature size, and the shoe last modeling method based on foot key size is to build a key contour curve through inputting the foot key size of a user and combine the contour curve into a shoe last curve frame for building shoe last sub-curves in blocks, and the shoe last sub-curves are spliced and faired for obtaining a whole shoe last curve; the shoe last modeling method based on a foot scanning model of the user introduces a user foot model, builds a foot feature model and a corresponding shoe last feature template, and combines the shoe last feature template and the contour curve to subdivide the initial grid surface of the shoe last feature template for obtaining a shoe last surface prototype; builds a unified shoe last model description; and adopts two modes of adjustment to the shoe last surface based thereon: scaling of the shoe last model based on size control or partial surface modification by adopting control points for adjustment. The invention realizes the shoe last modeling method without solid last.

Description

technical field [0001] The invention relates to shoe lasts, in particular to an interactive shoe last modeling method based on the characteristic dimensions of human feet. Background technique [0002] With the rapid reduction of computer technology and hardware costs, CAD / CAM technology has been widely used in the shoe industry, and the shoe last modeling system in shoe CAD should occupy a very important position. The traditional shoe last shape is generally carried out according to the corresponding national standards. However, with the increase of customer needs, personalized customization has increasingly become the commanding heights of enterprise competition. Therefore, there are more and more urgent needs to carry out shoe last design according to the customer's foot shape. At present, domestic shoe last CAD products mostly use standard lasts for shoe last shape design. The specific process is to establish the surface of shoe last through data sampling of standard l...
