Model Construction from a Single Perspective View using Shape from Symmetry
C. I. Attwood, G. D. Sullivan, K. D. Baker · 1993
A new method is described - Struct we from Symmetry (SFS) - in which objects possessing bilateral symmetry may be reconstructed from a single perspective view. The algorithm exploits the groundplane constraint [9, 14] and assumes a camera model, to allow 3D recovery up to scale. The SFS algorithm has been implemented in the form of an interactive tool. The user marks a set of symmetric object points in an image, and a complete facet model description is generated as output. The tool has been extensively used to create models for the vision system developed in the VIEWS project. The algorithm has potential for automatic structure recovery if methods for identifying symmetry points can be improved.
