Robust and Exhaustive Method for Symmetry Detection from Scanned Meshes

Tomohiro MIZOGUCHI, Satoshi KANAI, Hiroaki DATE, Hiroyuki TANAKA
2013 Journal of Advanced Mechanical Design, Systems, and Manufacturing  
Detecting such symmetries from their scanned meshes enables advanced applications, such as feature-based CAD model reconstruction or mesh size reduction for efficient CAE.  ...  In this paper, we propose a new method for detecting a common class of symmetries in engineering, such as translation, rotation and reflection, from scanned meshes of a variety of objects ranging from  ...  However, such a direct approach may fail to detect local symmetries which appear in a small area.
