Problems solved by technology

[0004] The purpose of the present invention is to provide a method for constructing a three-dimensional parametric digital avatar combined by parts. First, the key parts of the human body curve change are classified separately, and then the parametric digital avatar is constructed according to the different types of combinations of the parts, and through The parameters of each key part are used to adjust the avatar, which solves the problem that the avatar constructed by the existing method cannot adapt well to the human body

Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] figure 1 It is the section curve of the circumference of the chest, waist and hips of the female body. From this figure, it can be clearly seen that the three-dimensional curves of the female bodies belonging to the same body type according to the current customary human body classification method are obviously different. Therefore, there must be existence of avatars built on this basis. Big error.

[0026] The present invention proposes to classify the human body according to different parts to distinguish the shape of the body circumference curve, such as figure 2 process shown,

[0027] a. Collect the surface data of the human body and obtain the length and circumference size data of each part of the human body.

[0028] A non-contact 3D body scanner can be used to scan and obtain a sufficient number (more than 500 people) of hu...

Abstract

The invention discloses a sub-site modular 3D parametric digital people platform creation method, selecting the basic parts describing the characteristics of the human body based on the body size data; according to the basic characteristics of the basic positions classify the basic parts; combine the different types of basic parts freely to constitute the overall people platform. The invention of the human platform creation is described through a number of key points of the characteristics of various parts, and the key points are obtained through regression equation. So it can achieve the goal of adjusting the type and size of the people platform's parts by parameters. It can reduce the design cost and shorten the design cycle of modern clothing, and the people platform and ergonomic design, and create the conditions for get more satisfied effects.

Description

technical field [0001] The invention belongs to the technical field of clothing design, and relates to a method for constructing a mannequin for clothing, in particular to a method for constructing a three-dimensional parameterized digital mannequin by combining various parts according to the curve change characteristics of various parts of a human body. Background technique [0002] An avatar is a standard model of the human body. Due to different races, body shape distributions are also different. For example, there are significant differences in the body shape distribution of Europeans, Americans, Japanese, and my country. In addition, the existing customary method of classifying human body shapes is to classify the entire human body shape as a whole through some key lengths and girth dimensions of the human body. For example, in my country's national size standard GB / T 1335-1997, the two dimensions of adult women's bust and waist are used as the basic size of clothing s...
