DETECTION OF A MOVABLE OBJECT WHEN 3D SCANNING A RIGID OBJECT
First Claim
1. A method for detecting a movable object in a location, when scanning a rigid object in the location by means of a 3D scanner for generating a virtual 3D model of the rigid object, wherein the method comprises:
- providing a first 3D representation of at least part of a surface by scanning at least part of the location;
providing a second 3D representation of at least part of the surface by scanning at least part of the location;
determining for the first 3D representation a first excluded volume in space where no surface can be present;
determining for the second 3D representation a second excluded volume in space where no surface can be present;
if a portion of the surface in the first 3D representation is located in space in the second excluded volume, the portion of the surface in the first 3D representation is disregarded in the generation of the virtual 3D model, and/orif a portion of the surface in the second 3D representation is located in space in the first excluded volume, the portion of the surface in the second 3D representation is disregarded in the generation of the virtual 3D model.

Abstract
A method for detecting a movable object in a location includes —providing a first 3D representation of at least part of a surface by scanning; —providing a second 3D representation of at least part of the surface by scanning; —determining for the first 3D representation a first excluded volume; —determining for the second 3D representation a second excluded volume; —if a portion of the surface in the first 3D representation is located in space in the second excluded volume, the portion of the surface in the first 3D representation is disregarded, and/or —if a portion of the surface in the second 3D representation is located in space in the first excluded volume, the portion of the surface in the second 3D representation is disregarded

51. A system for detecting a movable object in a location, when scanning a rigid object in the location by means of a 3D scanner for generating a virtual 3D model of the rigid object, wherein the system comprises:
-
means for providing a first 3D representation of at least part of a surface by scanning at least part of the location; means for providing a second 3D representation of at least part of the surface by scanning at least part of the location; means for determining for the first 3D representation a first excluded volume in space where no surface can be present; means for determining for the second 3D representation a second excluded volume in space where no surface can be present; means for disregarding the portion of the surface in the first 3D representation in the generation of the virtual 3D model, if a portion of the surface in the first 3D representation is located in space in the second excluded volume, and/or means for disregarding the portion of the surface in the second 3D representation in the generation of the virtual 3D model, if a portion of the surface in the second 3D representation is located in space in the first excluded volume.
