Embodiment

[0087] Embodiment: FIG. 1 is a flow chart of automatic generation of a three-dimensional virtual human body. According to the automatic generation process of 3D virtual human body, this

Embodiment approach

[0088] The implementation of the method is as follows:

[0089] Step 1: The customer submits two digital photos of the human body (front and side), which are then accepted by the "Extraction of Customer Body Shape Information" part of the process diagram, which uses the "Rules for Obtaining Human Body Shape Feature Information from Two-dimensional Digital Photos" Obtain the customer's front and side body shape profile information as shown in Figure 4 and body shape geometric feature information. Figure 5 is a schematic diagram of the position where the system extracts body shape geometric feature information for a certain customer. The following table shows the corresponding shape geometric feature information.

Abstract

This invention relates to one three-dimensional virtual body automatic generation method based on body part module and outline, which comprises the following steps: according to frame special property cutting the body into three sections for breast section, waist section, bug section; on this base, analyzing each section into one set of relative key sections to reflect the geometry shapes of sections as body parts; any one 3D virtual body forming can be as body module to modify and resemble the body outline.

Description

technical field [0001] The invention relates to a digital human body and a graphic image processing method, in particular to an automatic generation method of a digital human graphic image for clothing design and production. Background technique [0002] At present, the construction of 3D virtual human body mainly focuses on feature-based human surface modeling, parametric surface modeling, polyhedron modeling, and 3D human body modeling with grid boundary lines as continuous conditions; in the construction of 3D human body based on 2D photos In terms of research, most of them are based on their own feature points to mark or modify the body contour to obtain the 3D human body, instead of obtaining the 3D human body model through the template matching of the human body part template series, and then modifying and positioning the contour control. For example, "A Model-Based Human Modeling System" Authors: Song Qingwen, Zhou Yuanhua, Source: Computer Application and Software, V...
