The invention relates to a coordinates-measuring device (1) comprising a sensor (7) for detecting coordinates of a work piece, a moving sensor carrier (6) which carries the sensor (7) and can be moved within a movement region relative to a base of the coordinates-measuring device (1), a position-determining device (10, 13; 23; 33) for determining a position and/or an orientation of the sensor carrier (6), an evaluation device that determines coordinates of the work piece from a position and/or orientation of the sensor carrier (6) determined by the position-determining device (10; 13; 23; 33) and from signals of the sensor (7), wherein the position-determining device (10; 13; 23; 33) has at least one camera (13; 23; 33) and at least one detection structure (31) that can be detected by the camera (13; 23; 33), wherein a) the camera (13; 23) is connected to the base (2) and the detection structure (31) or at least one of the detection structures is connected to the sensor carrier (6) and or is formed by the sensor carrier (6), or b) the camera (33) is connected to the sensor carrier (6) and the detection structure (31) or at least one of the detection structures (31) is connected to the base (2) and/or is formed by the base (2), wherein the position-determining device (10; 13; 23; 33) is configured to determine the position and/or orientation of the sensor carrier (6) from detection signals of the camera (13; 23; 33), with which the camera (13; 23; 33) detects the detection structure. |
