Example Embodiment

[0037] This embodiment relates to a method for automatically setting the spatial position of a three-dimensional clothing pattern. For the overall steps, see figure 1 .

[0038] Step 1: Read a three-dimensional human body model into the computer. The three-dimensional human body model can be represented by a triangular mesh surface or a quadrilateral mesh surface. figure 2 Shown is a full-body mannequin for clothing design. The three-dimensional human body involved in this patent includes not only the whole body, but also various 2 / 3-body or half-body models used for three-dimensional clothing cutting.

[0039] Step 2: Generate the characteristic points and characteristic lines of the three-dimensional human body model, and identify various parts of the human body. The characteristic points of the human body model include neck, shoulders, elbows, hands, chest, waist, hips, crotch, knees, ankles, etc. For different types of three-dimensional human body models, their feature point...

Abstract

A spatial position automatic setting method of a three-dimensional clothing pattern is disclosed. The spatial position automatic setting method comprises the steps of reading a three-dimensional human body model; generating a feature point and a feature line of a three-dimensional human body model, and identifying each part of the human body; automatically generating a spatial surrounding conical surface of each part of the three-dimensional human body model; generating a two-dimensional human body contour line of the three-dimensional human body model, the two-dimensional human body contour line including contour lines of left, right, front and rear sides; reading a two-dimensional clothing pattern; setting stitching information of the two-dimensional clothing pattern, and conducting triangular mesh processing of the two-dimensional clothing pattern; moving the two-dimensional clothing pattern to the position around the two-dimensional human body contour line in the step 4); calculating related parts of the human body to the two-dimensional clothing pattern; and mapping the two-dimensional clothing pattern onto the spatial surrounding conical surface of each part of the three-dimensional human body model, and obtaining spatial positions of the clothing pattern around the human body model. The method has the characteristics of high speed, high automation degree and simple operation.

Description

technical field [0001] The invention relates to a three-dimensional garment simulation method, in particular to a method for automatically setting the spatial position of a three-dimensional garment pattern. Background technique [0002] Three-dimensional clothing simulation is widely used in computer animation, clothing CAD and virtual fitting. On the one hand, the realistic three-dimensional clothing simulation can be used by fashion designers to evaluate the design effect of clothing, and on the other hand, consumers can understand the effect of clothing without trying it on. Three-dimensional clothing simulation technology reduces the design time of clothing by simulating the production process of clothing, and greatly shortens the design cycle of clothing. With the development of clothing e-commerce, the emergence of online virtual fitting technology has become inevitable. It can try on the clothes selected by the user on the virtual model to realize remote virtual fi...
