Title: MEASURING DEVICE HAVING A SCANNING FUNCTIONALITY AND A SINGLE-POINT MEASUREMENT MODE
Abstract:
The invention relates to a measuring device, comprising a base that defines a vertical axis, an assembly that can be pivoted about the vertical axis relative to the base, and a beam deflecting unit for varying the orientation of a measurement axis, wherein the beam deflecting unit can be rotated about a horizontal axis relative to the assembly. The measuring device further has a distance measurement functionality for measuring distance by means of the measurement radiation, an angle measurement functionality for determining an orientation of the measurement axis relative to the base, a control and processing unit for processing data and for controlling the measuring device, and a scanning functionality, wherein when the scanning functionality is executed, a scan is performed, and a point cloud comprising the scan points is produced. The assembly also has an imaging system, which has an imaging lens system and an image plane for producing and graphically providing an image of the field of view, wherein the field of view is defined by the imaging system and the beam deflecting unit and can be oriented together with the measurement axis by means of the beam deflecting unit and the image of the field of view can be provided graphically sharp in the image plane by means of image focusing by a focusing group. The measuring device has a single-point measurement mode, wherein in the single-point measurement mode the measurement axis can be oriented toward a target point, the distance to the target point and the orientation of the measurement axis can be determined, and a position of the target point can be determined in accordance with the distance and the orientation of the measurement radiation.
