  • Publication number: 20260022926
    Abstract: An articulated coordinate measuring machine comprising a set of sensors, a probe for approaching an object point, and a set of members connecting the probe to a base. The probe is configured to be moved at least partially manually by an operator holding and guiding the probe and/or a handheld member of the set of members. The coordinate measuring machine comprises (i) an accuracy-assessment-functionality providing accuracy-perception-data based on continuously monitored actual data representing an actual state of said at least one state variable of the coordinate measuring machine during the guiding of the probe, and (ii) a user-support-functionality providing a support action during the guiding of the probe based on the accuracy-perception-data.

  • Patent number: 12028506
    Abstract: A method for numerically compensating imaging errors caused by a geometrical deformation of a stereo camera is provided. An inertial variable vector is provided that is determined by an accelerometer, which inertial variable vector is expressed in a stereo camera coordinate system with a known geometrical relationship between the stereo camera coordinate system and the world coordinate system, and which inertial variable vector relates to a physical force which at least partly causes the geometrical deformation of the stereo camera. A calibrated analytic deformation model of the stereo camera is evaluated with the inertial variable vector as input. Updated external camera parameters are determined. The updated external camera parameters and known internal camera parameters of the two cameras are used for stereophotogrammetric analysis of images acquired by the stereo camera.
