1. A method for the three-dimensional digitization of objects (2) with a 3D sensor (10), which comprises a projector and one or more cameras, in which a pattern is projected onto the object (2) by the projector and the pattern is detected with the one or more cameras, wherein with the 3D sensor (10) at least three reference marks (14) and/or a reference raster are projected onto the object (2), and the reference marks (14) or raster are detected with two or more external, calibrated digital cameras (12),wherein the 3D sensor is calibrated to a first coordinate system and the digital cameras are calibrated to a second coordinate system different from the first coordinate system.
