    Abstract: Disclosed is 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/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.

    Abstract: According to an embodiment, a system for measuring a depth of a periodontal pocket defined by a gap between a tooth and gingiva is disclosed. The system includes a frame, at least one camera, and a processor. The frame is configured to be worn by a user. The at least one camera is attached to the frame and configured to capture at least one 2D image of an intraoral target area. The at least one 2D image includes a representation of at least a part of the tooth, a gingiva margin defined by a section of the gingiva adjacent to the at least a part of the tooth, and a probe tip when the probe tip is inserted into the periodontal pocket. The processor is configured to receive the captured at least one 2D image. The processor is further configured to determine, in relation to the gingiva margin, an insertion length of the probe tip in the periodontal pocket by applying an image processing technique on information obtained about the probe tip in the captured at least one 2D image. The determined insertion length represents the depth of the periodontal pocket.

    Abstract: Disclosed is a method and a scanner system for scanning interior surfaces, where the method comprises: - providing a probe shaped scanner having an axis, where the probe shaped scanner comprises: • at least one light source configured to create and project structured light, and • at least one camera configured to record 2D images; - entering said probe shaped scanner into a cavity of an object, where said cavity is bounded by an interior surface of the object; - creating and projecting structured light from said 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 said series of 2D images to obtain 3D real world coordinates of the interior surface; and - providing data and processing said data such that surface information for areas of the surface, where image scanning is not complete, is created. The scanner system may comprise a probe shaped scanner, a data conversion device and a data processing device, optionally all integrated in one device. (fig.15 should be published)
