Measuring device having a scanning functionality and a single-point measurement mode

A surveying instrument, comprising

• a beam source for generating measurement radiation,
• a base defining a vertical axis,
• a structure pivotable about the vertical axis relative to the base, comprising a beam entry window and a beam exit window, wherein the beam entry window and the beam exit window are identical,
• a beam deflection unit for varying the alignment of a measurement axis defined by an emission direction of the measurement radiation, wherein the beam deflection unit
• is rotatable about a horizontal axis relative to the structure and
• is arranged relative to the structure in such a way that
• measurement radiation emerging from the beam exit window is incident on the beam deflection unit and can be guided by means of the latter to an object, and
• measurement radiation reflected by the object and incident on the beam deflection unit is directed thereby onto the beam entry window,
• a distance measurement functionality for measuring the distance to the object by means of the measurement radiation,
• an angle measurement functionality for determining an alignment of the measurement axis relative to the base,
• a control and processing unit for data processing and for controlling the surveying instrument, and
• a scanning functionality, wherein, when the scanning functionality is carried out in an automatically controlled manner by the control and processing unit, there is scanning with
• rotating the beam deflection unit about the horizontal axis and pivoting the structure about the vertical axis simultaneously,
• determining the respective distance and the respective alignment of the measurement radiation for scanning points lying within a certain scanning region with a predetermined scanning point resolution, and
• generating a point cloud comprising the scanning points,
• wherein
• the structure furthermore comprises an imaging system comprising an imaging optical unit with a focusing group and an image plane for generating and graphically providing an image of a field of view, wherein
• the field of view is defined by the imaging system and the beam deflection unit and can be aligned together with the measurement axis by means of the beam deflection unit and
• the image of the field of view can be provided graphically in focus in the image plane by means of image focusing using the focusing group, and
• the surveying instrument has a single-point measurement mode, within the scope of which
• the measurement axis can be aligned onto a target point, and
• when a single-point measurement is triggered in an automatically controlled manner by the control and processing unit, the distance to the target point and the alignment of the measurement axis and a position of the target point can be determined depending on the distance and on the alignment of the measurement axis.
