Abstract
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.
Claims21
A method for determining a distance from a 3D point to a 3D surface from a 2D projected range image comprising:
- determining a projected distance from the 3D point to the 3D surface using the projected range image;
- determining a cliff distance from the 3D point to a nearest cliff in the 3D surface using the projected range image;
- and
- combining the projected distance and the cliff distance to determine the distance from the 3D point to the 3D surface.
