Abstract: The present disclosure provides a computer-implemented method for correlating at least one infrared 2D-image to a 3D-representation of at least a part of a tooth displayed in a graphical user-interface, of a hand-held scanning device, on a screen, comprising the steps of: obtaining a first set of 2D-images of the at least part of the tooth; forming a 3D-representation of the at least a part of the tooth from the first set of 2D-images; displaying, in the graphical user-interface, the 3D-representation; obtaining a second set of 2D-images, wherein the second set of 2D images are infrared 2D-images acquired within the at least part of the tooth; displaying, in the user-interface, at least one of the 2D-images from the second set of 2D-images; displaying, in the user-interface, a manipulator configured to change between 2D-images in the second set of 2D-images.

Abstract: According to an embodiment, a method for 3D scanning at least a part of a surface of an object is disclosed. The method includes recording, using an optical scanner comprising at least one camera, one or more test 2D images of the at least a part of the surface of the object; automatically identifying a first segment of a first level of interest within the test 2D images, the first segment imaging a region of interest on the at least a part of the surface of the object; identifying a first 3D volume comprising the region of interest of the at least a part of the surface of the object; selecting a first input defining a first resolution and/or a first coverage; and 3D scanning the at least a part of the surface of the object within the first 3D volume using the first input.

Abstract: Disclosed is an optical coherence tomography scanner and a method for recording sub-surface scans of an object, wherein a position encoder is arranged in the path of the probing beam of an interferometric system. The encoder pattern is detected in a sequence of A scans at generated for different probing beam positions on the scanned object, the probing beam position and/or inclination for at least one A scan of said sequence of A scans is deducing based on the detected encoder pattern, and the sub-surface scan of the object is generated based on the sequence of A scans taking into account the deduced probing beam position and/or inclination.
