Abstract: A surveying instrument, comprising at least one rotational movement axis such as a azimuth axis, which is for providing a positioning of the measurement direction of the surveying instrument, a rotational position encoder configured for deriving a rotational direction value around the movement axis and an acceleration sensor such as a MEMS-accelerometer for deriving a leveling for the surveying instrument and being rotatable around the rotational movement axis in different rotational positions. The instrument further comprises a mechanism designed to move the accelerometer from a first orientation in at least a second orientation, the second orientation being different to the first orientation, wherein the mechanism is designed and arranged in such a way that the targeting direction is uninfluenced by a movement of the accelerometer by the mechanism, and an evaluation unit configured to derive a calibrated leveling for the instrument.

Abstract: A survey instrument comprising a single point measurement unit, a point cloud measuring module, and a computing unit. The single point measurement unit is configured to generate first measurement data comprising coordinates a point. The point cloud measuring module has a fixed pose relative to the single point measurement unit, and configured to generate a second measurement data comprising coordinates of a plurality of points. The computing unit stores calibration parameters and is configured to generate a point cloud based on the second measurement data, to merge it with the first measurement data and to detect surfaces and object edges in it. The survey instrument is configured to execute a calibration using object edges in the setting. The single point measurement unit acquires a set of single measuring points including at least two on each flat surfaces of the object edges.

Abstract: An industrial or geodetic surveying device with a scan functionality including an alidade rotating about a standing axis and a telescope unit with a beam exit for a laser measuring beam. The telescope unit is mounted on the alidade and is movable in a tilting motion about an elevation axis substantially orthogonal to the standing axis. The scan functionality comprises a scan sequence with an angular velocity of the alidade around the standing axis, wherein during the scan sequence the alidade is in a continuous revolving motion with mainly constant angular velocity about the standing axis, and the angular velocity of the alidade is faster than half of the angular velocity of the tilting motion of the telescope unit about the elevation axis.
