Superquadric representation of automotive parts applying part decomposition

Superquadrics based 3D object representation of automotive parts utilizing part decomposition

We present a new superquadrics based object representation strategy for automotive parts in this paper. Starting from a 3D watertight surface model, a part decomposition step is first performed to segment the original multi-part objects into their constituent single parts. Each single part is then represented by a superquadric. The originalities of this approach include first, our approach can ...

Superquadric Representation of Scenes from Multi-view Range Data

Object representation denotes representing three-dimensional (3D) real-world objects with known graphic or mathematic primitives recognizable to computers. This research has numerous applications for object-related tasks in areas including computer vision, computer graphics, reverse engineering, etc. Superquadrics, as volumetric and parametric models, have been selected to be the representation...

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 p...

Three-dimensional Assembly Synthesis for Robust Dimensional Integrity Based on Screw Theory

This paper presents a 3D extension of our previous work on the synthesis of assemblies whose dimensional integrity is insensitive to the dimensional variations of individual parts. Assuming that assemblies can be built in the reverse sequence of decomposition, the method recursively decomposes a given product geometry into two subassemblies until parts become manufacturable. At each recursion, ...
