摘要:
A method for optically measuring an object by means of an optical recording apparatus includes a triangulation method. A first shutter means is used to produce a first pattern and to project the first pattern as a first projection beam onto the object to be measured. At least one further shutter means is used to produce a further pattern and to project the further pattern as a further projection beam onto the object to be measured. The first pattern and the further pattern are passed back from the object as observation beams and are recorded by at least one recording means in order to obtain a three-dimensional data record of the object. The projected first pattern and the further pattern are recorded at the same time in at least one triangulation recording using the at least one recording means.
