In a method for determining the 3D coordinates of an object a pattern () is projected onto the object () by a projector (), the light reflected by the object () is captured by a camera (), and the shots recorded by the camera () are evaluated. Reference marks () on and/or beside the object () are recorded by a reference camera (). The reference camera () has a larger field of view () than the camera (). To improve such method, the reference camera () is connected with the camera () or with a 3D sensor () which comprises the projector () and the camera ().

Method and apparatus for determining the 3D coordinates of an object

A method serves for the determination of the 3D coordinates of an object. An improved method of this kind is characterized in that the object is surrounded by a plurality of reference probes having coded reference marks; and in that a plurality of shots are taken of the object such that a part of the object and a part of a reference probe is in each case included thereon.

Method for the determination of the 3D coordinates of an object

This invention relates to a method and an apparatus for the three-dimensional digitization of objects with a 3D sensor, which comprises a projector and one or more cameras, in which a pattern is projected onto the object by means of the projector, and the pattern is detected with the one or more cameras. In accordance with the invention, the method and the apparatus are characterized in that at least three reference marks and/or a reference raster are projected onto the object with the 3D sensor and are detected with two or more external, calibrated digital cameras.
