ABSTRACT:
A separation from at least one and an image of at least three reflective regions on the orientation indicator are recorded by a separation measurement sensor and an image sensor in a measuring device, for the purpose of determining the orientation of an orientation indicator. The separation measurement and image recording are achieved by means of a directed emission of a collimated first beam and a divergent second beam with differing wavelengths and/or polarization in the direction of the orientation indicator and a simultaneous recording of the reflected and/or scattered first and second beams. The reflective regions on the orientation indicator are embodied and arranged such as to be positioned at a target point with a detectable geometric relationship to each other and to be simultaneously resolved by the image recorder. By means of the orientation determination, amongst other things, separations from target points, even not directly visible, can be precisely determined.
