Method for obtaining Euclidean distance from point in 3D space to 3D object surface from projection distance image stored in memory having projection distance along projection direction from projection plane to 3D object surface as pixel value

摘要

A method determines a distance from a 3D point to a 3D surface from a 2D projected range image. A projected distance and a cliff distance from the 3D point to the 3D surface are determined using the projected range image. The projected distance and the cliff distance are then combined to determine the distance from the 3D point to the 3D surface.
