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.
