The invention relates to a method for optical measurement of an object using a triangulation method, by means of an optical recording apparatus (1). A first shutter means (3.1) is used to produce a first pattern (11.1) and to project this as a first projection beam (7.1) onto the object (8) to be recorded. At least one further shutter means (3.1-3.4) is used to produce a further pattern (11.2-11.4) and to project this onto the object (8) to be recorded, as a further projection beam (7.2-7.4). The first pattern (11.1) and the further pattern (11.2-11.4) are passed back from the object (8) as observation beams (13.1-13.4) and are recorded by at least one recording means (6, 6.1, 6.2) in order to obtain a 3D data record (21) of the object. The projected first pattern (11.1) and the further pattern (11.2-11.4) are recorded at the same time in at least one triangulation recording (20, 53, 54), using the at least one recording means (6, 6.1, 6.2). |
