  • Publication number: 20240135641
    Abstract: A survey instrument comprising a single point and a point cloud measuring functionality, a communication interface, and a computing unit. The point cloud measuring functionality configured to emit a scanning beam along a first measuring axis and to advance the first measuring axis along a scanning pattern. The point cloud measuring functionality is configured to generate point cloud data representing a setting. The single point measuring functionality is configured to emit a measuring beam along a second measuring axis. The first measuring axis is referenced to the second measuring axis. The communication interface is configured to receive model data representing at least a part of the setting and comprising referencing data to an external coordinate system.

  • Publication number: 20220187069
    Abstract: A surveying pole and to a secondary sensor unit which is attachable to the surveying pole. A reflector and/or GNSS receiver attachable to the surveying pole can be attached independently of whether or not the secondary sensor unit is attached to the surveying pole. A distance between the reflector and/or GNSS receiver and a pole tip is also independent of whether or not the secondary sensor unit is attached to the surveying pole. A distance between an attached reflector and/or GNSS receiver and the attached secondary sensor unit is also known and fixed. A method and computer program product for numerically correcting distance measurement errors due to reflector orientation and position with respect to a primary sensor, in particular a tachymeter.

  • Patent number: 11333497
    Abstract: A coordinate measuring and/or stake out device can be designed for being hand-held (one-handed), free carriage and movement by a user. A position giving means is for determination of an actual translational position of the device using an external position reference and an orientation giving means for determination of an actual rotational position of the device, such that the actual position of the device with respect to all six degrees of freedom of the device can be determined. A radiation source is for generation of a radiation beam as measuring and/or marking beam for measuring and/or visually marking of an object point. A beam steerer is for automatic steering of an alignment of the beam, whereby the beam which differ in the manner of automatic steering the beam alignment.

  • Publication number: 20220090910
    Abstract: A method comprising: setting up a stationary surveying device at a first known positioning in a surrounding area of the object; retrieving from a memory a set of object points of an object to be surveyed and/or to be marked; surveying and/or marking from a first positioning object points of the set of object points that can be surveyed and/or can be marked from the first positioning by means of the free beam, on the basis of a target direction; ascertaining missing object points of a set of object points; relocating the surveying device to a second, unknown positioning in the surrounding area of the object; automatically determining a second positioning by the surveying device on the basis of the knowledge of the first positioning, so that the second positioning is known; surveying and/or marking missing object points by means of the free beam from the second positioning.
