Problems solved by technology

[0004] The present invention is to overcome the traditional experience-based plate-making and trial-and-error methods that lack scientific basis and guidance, solve the technical problem of poor fit of bra cups, provide a three-dimensional virtual breast-shaped environment, and realize three-dimensional personalized bra cups to expand into two-dimensional bra cups The provincial tailor-made design method embodies the concept of human-oriented bra design, avoids the status quo of storing a large number of physical bra models, reduces costs, improves efficiency, and meets the increasing production demand for tailor-made fit bras.

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Principle and concrete steps of the inventive method are as follows:

[0027] 1. Establishment of 3D female human torso:

[0028] The most direct method of human body modeling is to read in the data of the external real human body (Figure 1). The 3D human body scanning system can generate tens of thousands of human body surface data points to form the original image of the point cloud. During the 3D scanning, the test subject stands upright with his legs slightly apart, his feet are slightly apart at the same level as the shoulder width, his arms are slightly separated from his torso, his upper body is naked, and his lower half 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. Then nor...

Abstract

The disclosed individual brassiere cup measurement method in 3D virtual breast shape environment comprises: 1. building basic breast shape model; 2. creating women breast shape model database; 3. expanding the 2D cup measurement in 3D virtual environment. Based on 3D body surface scanning data and feature parameter, this invention simulates special body 3D breast shape and molded shape to fast obtain matched cup measurement, reduces design cost, and satisfies individual request.

Description

technical field [0001] The invention belongs to a bra cup quantity-saving design method in the bra production and plate making process, in particular to a three-dimensional personalized bra cup unfolded into a two-dimensional bra cup in a three-dimensional virtual breast shape environment. Background technique [0002] Bras are the most intimate enjoyment and care for women. Because small bras need to be close to the body after wearing, shape the breast shape, not fall off, and not be tight, the cup pattern design of the bra, especially the saving design, has always been considered a One of the key factors affecting the fit of bras and one of the most difficult techniques. Traditionally, bra pattern-making generally uses the method of repeated samples to improve the pattern, which is inefficient and poor in fit. Even if the conventional breast shape model is constructed to solve the cup and save the amount, it is very difficult to deal with the specia...
