Abstract: The invention relates generally to a metrology system and coordinate measuring devices to be used within the framework of a smart factory environment, which has a defined arrangement of different metrology devices, configured such that coordinate measuring data generated by different metrology devices are referencable to a common coordinate system.

Abstract: A measurement system for determining six degrees of freedom (?, ?, d, ?, ?, ?) of a reflector (2) or of an object (3) on which the reflector is arranged, comprises an angle- and distance measurement apparatus (1), e.g. a laser tracker, operating with a laser beam as a measurement beam (4). The reflector (2) is designed for a parallel reflection of the measurement beam (4) and has an apical opening or surface (6), in a manner such that a part of the measurement beam (4) directed onto the reflector (2), passes through the apical opening or surface (6), and is incident on a light-sensitive surface (7) arranged behind the reflector apex. Five degrees of freedom (?, ?, d, ?, ?) of the reflector (2) or the object (3) are computed from measurement data produced by the angle- and distance measurement apparatus (1) and by the light-sensitive surface (7).

Abstract: For indirect determination of point positions and/or of surface orientations in point positions a laser tracker (1) adapted for relative and absolute distance measurement is used. A measuring device is utilised, the device including a target point (retro-reflector 3) for the laser beam of the tracker, the target point being movable along a trajectory path (A). The position and orientation of the trajectory path (A) of the target point is precisely defined relative to a reference point (R) of the device (2) and the device (2) is positionable in the region of a point position (P) to be determined such that the position of the reference point (R) relative to the point position (P) to be determined is precisely defined. For determining the point position (P), the device (2) is positioned in the region of the point position (P) to be determined, the target point is positioned in a starting position (3.1) and is detected by the tracker (1) by direction determination and absolute distance measurement.

Abstract: Using a laser-tracker (1) with an interferometer together with a retroreflector (3) in the form of a triple prism or a triple mirror arranged on an object and designed for parallel reflection of the laser beam (5) directed to the reflector (3), the position of the object is computed by way of measurement data with respect to the direction of the laser beam (5) and its path length. Additionally the spacial orientation of the object (2) is determined by producing additional measurement data with respect to the angle of incidence (&agr;) of the laser beam into the reflector (3) and/or with respect to an adjustable orientation of the reflector (3) relative to the object (2) and by computing the position and spacial orientation of the object (2) by way of measurement data with respect to the direction and the path length of the laser beam (5) and by way of this additional measurement data.
