  • Publication number: 20200348133
    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: 20200292310
    Abstract: A surveying system can include a surveying instrument, a control system, a tilt measuring system, a levelling unit, a camera system, and a second distance meter, wherein the control system is configured for obtaining an image position of a captured image, adjusting a tilt status until a first tilt status is obtained, the second distance meter aiming onto the location on the ground in the first tilt status, determining the first tilt status, effecting the second distance meter to measure a distance to the location on the ground, effecting a first angle encoder to measure a rotatory position of a support unit, effecting the levelling unit to adjust the tilt status, and calibrating a preconfigured centre point based on the distance to the location on the ground, a deviation between the first tilt status and the second tilt status, and/or the rotatory position of the support unit.

  • Patent number: 10753740
    Abstract: A geodetic surveying instrument, such as a total station, stationed with instrument center coordinates at ground coordinates in a stationing height above ground. The instrument comprises a sighting unit for aiming a measurement target point, with an opto-electronic distance meter to determine a target distance and two axes for aiming the sighting unit, with goniometers to determine a target direction. It also comprises a tilt sensor to determine a tilt value of the instrument and a measurement-controller to derive measured coordinates of the measurement target point based on this target direction and target distance.

  • Publication number: 20190285434
    Abstract: A total station configured for receiving from a camera a first image captured in a first face and a second image captured in a second face, wherein in the second face the camera is rotated around the optical axis by between 170° and 190° compared to the first face, receiving at least one of an azimuthal angle pair and an elevative angle pair, said azimuthal angle pair comprising a first azimuthal angle and a second azimuthal angle, and said elevative angle pair comprising a first elevative angle a second elevative angle, matching the first image and the second image with a relative rotation and a relative translation, determining the relative rotation of the matched first image and second image, determining the relative translation of the matched first image and second image, based on the respective angle pair, the relative rotation, the relative translation, and determining an instrument error.
