Structure-consistent customized virtual mannequin reconstruction from 3D scans based on optimization

Abstract

The 3D virtual mannequin has been widely used in apparel industry, and its importance is also increasing. This work develops a new 3D virtual mannequin reconstruction system based on optimization. All the mannequins reconstructed by the proposed approach share the identical topology, that is, there is a point-to-point correspondence among the mannequins, which will significantly facilitate much subsequent processing in fashion design, made-to-measure, and virtual try-on. The inputs to the proposed system contain a template human body, a raw scan (represented in mesh), and a very sparse corresponding landmarks set. The proposed approach substantially utilizes the optimization technology to drive the template to deform into a real scan. There is no special requirement on the raw meshes. The raw meshes may have a different number of vertices and triangles or may even be incomplete. The proposed method only needs 21 landmarks as hard-constraints to reconstruct a mannequin with tens of thousands of vertices. These landmarks can be extracted automatically for standard mannequin reconstruction. Besides the standard mannequin, the proposed system can also be used to reconstruct display mannequins, that is, mannequins with various poses. The experiments visualize the optimization procedure and verify that the optimization is efficient and effective. Quantitative analysis also proves that the reconstruction error satisfies the requirements of fashion design and tailoring.

A new parametric 3D human body modeling approach by using key position labeling and body parts segmentation

“…However, the rapid and realistic realization of a 3D human body model under existing conditions requires a solution. 11 In recent years, many scholars have proposed various methods for human body modeling, which can be divided into creation and reconstruction. 12,13 Various 3D human body creation and reconstruction methods are based on 3D scanning.…”

“…They are generated from the parameter space of a statistical model and some key measurements, such as waist, chest and even body shape, which are highly unconstrained and uncontrollable. 11 Furthermore, the standard SMPL template is the T-pose pose, that is, arms extended at shoulder height, palms parallel to the ground, palms down, and feet slightly open, but not together. It is not the natural standing position of a person.…”

Design of a multi-sensor information acquisition system for mannequin reconstruction and human body size measurement under clothes

“…For many applications, such as garment design, virtual fitting and tailoring, mannequins have an important role. [1][2][3] In the garment manufacturing industry, for instance, largescale machine production has replaced manual production, which has greatly increased output and reduced manufacturing costs, but at the same time has created overproduction. 4 Only garment customization can solve the production capacity, achieve zero inventory, guide accurate consumption and realize accurate manufacturing.…”
