Abstract: A 3D scanner system includes a scanning device capable of recording first and second data sets of a surface of an object when operating in a first configuration and a second configuration, respectively. A measurement unit is configured for measuring a distance from the scanning device to the surface. A control controls an operation of the scanning device based on the distance measured by the measurement unit, where the scanning device operates in the first configuration when the measured distance is within a first range of distances from the surface and the scanning device operates in the second configuration when the measured distance is within a second range of distances; and a data processor is configured to combine one or more first data sets and one or more second data sets to create a combined virtual 3D model of the object surface.

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 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.
