Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the lack of human body data basis and guidance in the traditional empirical plate-making and two-dimensional plate-making methods, so that it is difficult to control the shape of the inner and outer curved surfaces of the cup, and then solve the technology of poor fit and plasticity of the industrialized large-scale production of Chinese bra cups question

Embodiment Construction

[0050]In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

[0051] Such as figure 1 As shown, the present invention provides a method for obtaining a three-dimensional model of a bra cup based on a three-dimensional chest shape, the steps of which are as follows:

[0052] The first step is to obtain the 3D model of the basic chest shape:

[0053] Step 1, 3D human body scanning:

[0054] Use the American TC2 3D scanner to scan multiple real human bodies. During the scan, the tested human legs are upright, the feet are slightly separated and shoulder-width level, the arms are slightly separated from the human torso, the upper body and chest are exposed, and the lower body is wearing tight shorts. Since the shape of the chest is only affected by the shape of the human torso, the scanned data of the limbs of the human body can be removed to reduce the complexity of data processing.

Abstract

The invention relates to a three-dimensional cup model obtaining method based on three-dimensional chest shapes. The method is characterized by comprising the steps that basic three-dimensional chest shape models are obtained; three-dimensional chest shape shaping models are obtained; three-dimensional intermediate body models are built, three-dimensional coordinates of a human body are extracted, the mean value of the sample coordinates is worked out, and an intermediate body characteristic matrix and a three-dimensional intermediate body model are built; a three-dimensional cup model is obtained. Due to utilization of the three-dimensional cup model obtaining method, the three-dimension cup model is designed and extracted based on ideal three-dimensional chest shapes to ensure that the capacity of a cup is matched with chest shapes and the cup can more fit the chest shapes, and the fitness and the comfort of brassieres are improved; three-dimensional chest shapes are directly converted to the cup model, and therefore design cost is reduced, working efficiency is improved, theoretical foundation for brassiere paper pattern design is provided, and the technical problem that a brassiere cup is poor in fitness is solved. The three-dimensional cup model obtaining method covers a large number of data on human bodies and ensures that the extracted brassiere cup can meet requirements of the crowd to the maximum degree, and meet industrial production requirements.

Description

technical field [0001] The invention relates to a method for acquiring a three-dimensional model of a breast cup. Background technique [0002] Breasts are the most eye-catching secondary sexual characteristics of women, and they are also an essential part of women's curves. Bras can not only help women shape perfect curves, but also serve as functional clothing that supports, fixes, covers and protects women's breasts. A well-fitting bra can protect the breast, prevent breast sagging, and create a beautiful breast shape, while an unfit bra not only does not protect the breast, but also causes breast damage, such as excessive pressure and breast deformation caused by too small a bra. Therefore, bra structural design is the core technology in bra design and production, and the structural shape of the cup is the main part that affects the shape and fit of a bra. Traditionally, bra plate-making uses the method of repeated samples to improve the pattern, especially the shape o...
