Abstract: A method for scanning partly obstructed interior surfaces includes providing a probe shaped scanner having an axis. The scanner includes at least one light source configured to create and project structured light, and at least one camera configured to record 2D images. The method includes entering the probe shaped scanner into a cavity of an object, where the cavity is bounded by an interior surface of the object; creating and projecting structured light from the light source of the probe producing a pattern on the interior surface of the object; recording a series of 2D images of the reflection of the pattern from the interior surface using said camera; combining the series of 2D images to obtain 3D real world coordinates of the interior surface; and providing data and processing the data such that surface information for areas of the surface, where image scanning is not complete, is created.

Abstract: Disclosed are a scanner system and a method for recording surface geometry and surface color of an object where both surface geometry information and surface color information for a block of the image sensor pixels at least partly from one 2D image recorded by the color image sensor. A particular application is within dentistry, particularly for intraoral scanning.

Abstract: Detecting a movable object in a location includes providing a first 3D representation of at least part of a surface; providing a second 3D representation of at least part of the surface; 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/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 in the generation of the virtual 3D model.
