Building Superquadric Men from 3D Whole-Body Scan Data

This paper describes a scheme for reconstructing 3D human models from whole-body scan data. The 3D human models are composed of superquadric primitives each corresponding to a functional body part. The reconstruction starts with primary segmentation of scan data, which defines the location of the articulation link in the human scan and results in topologically simple (primary) body parts. The primary body parts are further decomposed into sub-parts suitable for superquadric representation. These segmented sub-parts are refined to achieve global compatibility and then fitted with superquadrics to complete our process. Being based on compact volumetric primitives, the whole reconstruction scheme is able to deal directly with raw scan data comprising 3D point clouds sampled on human body surfaces. Both qualitative and quantitative evaluations of the method are conducted.
