Embodiment Construction

[0057] The present invention will be further described below in conjunction with accompanying drawing:

[0058] The present invention solves the technical scheme that its technical problem adopts, concrete steps are as follows:

[0059](1) Preparation of 3D point cloud data of human torso. For the 3D data model of the human torso, the whole body 3D model data file (wrml file) can be obtained first through the TC2 3D body scanning system. Through the 3D body scanner, the file is divided into seven parts: RightLeg, LeftLeg, Torso, LeftArm, RightArm, Left Hand, Right Hand. Among them, each part is mainly composed of two types of data: (1) a point matrix (point) composed of three-dimensional coordinates (x, y, z) arranged row by row; (2) a coordinate sequence number index that constitutes a three-dimensional grid facet The index matrix ( coordIndex ). After deleting the limbs and head data, obtain the 3D point cloud data of the human torso, and then use 3DS Max and other 3D gra...

Abstract

The invention relates to a method for generating a garment body prototype model based on a personalized three-dimensional virtual dress form. The method comprises the steps as follows: firstly, carrying out treatments such as section curve fitting, re-sampling, symmetrization, convex hull calculation, translation and curve fitting of inwardly recessed zone points and the like on three-dimensional data of a human body trunk to obtain the symmetric virtual dress form with a similar effect of wearing a body fitting garment; secondly, defining characteristic points and lines on the three-dimensional dress form of a half body, and further subdividing zone curves; and lastly, carrying out two-dimensional expansion on the three-dimensional curves to generate the personalized garment prototype model. The three-dimensional virtual dress form obtained by utilizing the method can be applied to personalized customization of industrial dress forms, the generated prototype model inherits the accuracy of the conventional three-dimensional curve expansion technology and can guarantee the structural characteristics of the conventional prototype, and the mature two-dimensional CAD (Computer Aid Design) technology can be made full use of in results for further model customization of garments with specific styles.

Description

technical field [0001] The invention relates to the technical field of clothing digital patterning, in particular to a method for generating a clothing body prototype template based on a personalized three-dimensional virtual avatar. Background technique [0002] With the development of information technology, the clothing industry has established a flexible and rapid response mechanism, which mainly includes the following aspects: the application of advanced CAD / CAM system, the application of information management systems such as ERP, the development and application of three-dimensional anthropometry technology, And the application of remote fitting system, etc. In addition, with the development of the economy and the demand for personalized clothing, mass customization has also become an important production mode of the clothing manufacturing industry in the 21st century. The 3D-based clothing model customization system is just a combination of 3D CAD technology and pers...
