Abstract: An optical measuring device for the three-dimensional optical measurement of objects includes a device housing in which a projection unit for projecting a measuring structure onto the surface of the object to be measured in a projection area and a camera unit configured to capture images of the object provided with the projected measuring structure are integrated. The device housing also has a sensor unit configured to detect persons in a sensor range covered by the sensor unit. The optical measuring device is configured to limit the light intensity to a level that is not dangerous for a person located in a danger area of the projection area when the presence of a person in the sensor area or part of the sensor area has been detected.

Abstract: A method for three-dimensional measuring of objects with triangulation includes projecting light structures onto an object, capturing the light structures with optoelectronic image capture, and computer-assisted evaluation of the captured images for measuring the object. The light structures are projected in a first wavelength range and the image capture detects the wavelength range that has the intensities caused by fluorescence of the object. The wavelengths emitted from the object are filtered when the projected light structures are captured. Both the wavelength range used for projecting light structures and the wavelength range having the fluorescence are detected for the same image capture and the transmission of the wavelength range having the fluorescence is larger than the transmission of the wavelength range used for projecting light structures. Electronic or electromechanical components and components made of plastics material are measured as the objects which have a self-fluorescent surface.

Abstract: A projector for an arrangement for three-dimensional optical measurement of objects (6) with the aid of a topometric measuring method in which images of projection patterns (2) projected onto an object (6) are acquired and evaluated, the projector having an illumination unit (4) and a carrier (1), provided with projection patterns (2), for projecting the light structures. The object is achieved by virtue of the fact that projection patterns (2) are arranged on the carrier (1) in the form of repeating geometrical individual structures, and the carrier (1) with the projection patterns (2) is movably arranged in such a way that during the movement and illumination selected regions of the projection pattern (2) are displaced into the beam path (7) between the illumination unit (4) and object (6), and a stripe-shaped pattern is imaged on the object (6) by means of the movement unsharpness.

Abstract: The device 1 is described for three-dimensional optical measurement of objects 2 using a topometric measurement method, in which images of projection patterns which have been projected onto an object 2 are recorded and evaluated. The device 1 has a projector 3 with a light source, an image recording unit 5 and an image evaluation unit 6. The light source for the projector 3 is an arc lamp 4, and the image recording unit 5 is designed for synchronization of image recording with the light intensity of the arc lamp 4.
