Probable reconstruction of surfaces in occluded regions by computed symmetry
First Claim
1. A system for obtaining a probable 3D map of an occluded surface of an object, the system comprising:
- an imager configured to acquire an initial 3D map of a visible surface of the object; and
a computing device configured toidentify one or more symmetries of the initial 3D map, andcompute the probable 3D map of the occluded surface from the one or more identified symmetries and the initial 3D map.

Abstract
A system for obtaining a probable 3D map of an occluded surface of an object is provided. The system receives an initial 3D map of a visible surface of the object and identifies one or more symmetries of the initial 3D map. The system computes the probable 3D map of the occluded surface by projecting points of the initial 3D map into occluded regions of space according to the identified symmetries. The system can also comprise an imager for obtaining the initial 3D map. The actual occluded surface cannot be known with absolute certainly because it is occluded; however, the computed 3D map will closely resemble the actual occluded surface in many instances because most objects possess one or more symmetries and the computed 3D map is based on such symmetries that are identified in the initial 3D map of the object.
