  • Patent number: 9020240
    Abstract: Noncontact coordinate measurement. With a 3D image recording unit, a first three-dimensional image of a first area section of the object surface is electronically recorded in a first position and first orientation, the first three-dimensional image being composed of a multiplicity of first pixels, with which in each case a piece of depth information is coordinated. First 3D image coordinates in an image coordinate system are coordinated with the first pixels. The first position and first orientation of the 3D image recording unit in the object coordinate system are determined by a measuring apparatus coupled to the object coordinate system by means of an optical reference stereocamera measuring system. First 3D object coordinates in the object coordinate system are coordinated with the first pixels from the knowledge of the first 3D image coordinates and of the first position and first orientation of the 3D image recording unit.

  • Patent number: 9007573
    Abstract: Automated autocollimation provides alignment of a telescope of a surveying instrument. The telescope defines an optical axis perpendicular to a reflective surface of an autocollimation target, such as a coated plane mirror. Alignment is performed by a method that includes aligning the telescope with the autocollimation target and illuminating a reticle in the telescope. The telescope is focused on infinite. The autocollimation target and the illuminated reticle reflected by the reflective surface, or the illuminated reticle, are acquired using an image acquisition device in the telescope or a second telescope. The reticle center in the image is determined. The horizontal and vertical distances of the reticle center are determined from the optical axis of the telescope in the image. The horizontal and vertical distances of the reticle center are converted into horizontal and vertical aberration angles of the current alignment of the telescope from the autocollimation alignment of the telescope.

  • Patent number: 9008988
    Abstract: A method of calibrating inertial sensors of working equipment, such as a vehicle or survey equipment, includes determining whether the working equipment is in operation or not. Data is captured from inertial sensors and associated temperature sensors while the working equipment is out of operation. The captured data is used to update a thermal bias error model for the inertial sensors.

  • Patent number: 8981297
    Abstract: A coordinate measuring device includes a carrier that can be rotated automatically about two axes and that can be directed toward a measuring aid. The following are arranged on the carrier so as to be able to move together: an optical distance measuring device for measuring the distance to the measuring aid; a light source for emitting light, directly or by means of optical elements, wherein said light is visible as a target point when reflected on the measuring aid; a target detecting unit for determining a position as the position of the imaging of the target point on a position detection sensor. The control apparatus is designed to direct the carrier at the measuring aid by rotating the carrier about the at least two axes of the carrier according to the fine position and the rough position; and the light source is a superluminescent diode (SLED).

  • Patent number: 8896843
    Abstract: A method for speckle mitigation in an interferometric distance meter comprises the steps of transmitting optical radiation with at least one wavelength ? to a target to be surveyed, receiving a portion of the optical radiation scattered back by the target in an optical axis (OA), wherein the optical radiation forms a speckle field, converting the received optical radiation into at least one received signal, determining a true distance to the target from the received signal by absolute or incremental interferometric distance measurements. In the method the true pointing direction relative to the optical axis (OA) is determined, wherein the distance error due to speckle effects is corrected.
