Global camera path optimization
WO 2010077380 A3
Abstract
Global path optimization is employed to refine a camera path used to reconstruct a three-dimensional image. In hand-held dental scanning, spatial links can often be made between non-sequential frames of data, such as between separate camera path segments for buccal and lingual tooth surfaces, and these spatial links can be employed to minimize motion estimation parameters in a global optimization process.
