  • Publication number: 20180135965
    Abstract: A method for scanning and obtaining three-dimensional (3D) coordinates is provided. The method includes providing a 3D measuring device having a projector, a first camera and a second camera. The method records images of a light pattern emitted by the projector onto an object. A deviation in a measured parameter from an expected parameter is determined. The calibration of the 3D measuring device may be changed when the deviation is outside of a predetermined threshold.

  • Publication number: 20180071914
    Abstract: A safety sensor system and method is provided. The method includes projecting from a projector a pattern of light to a first position. The pattern of light being generated by a shape control element with each of the first pattern of light having a pattern pose. A first image is captured with a camera of the first pattern of light. The pose or shape of the pattern of light is changed using the shape control element. A pattern pose or shape information is determined from both images. It is determined that the second image is valid based on the pattern pose or shape information differing by more than predetermined measurement errors or the pattern pose or shape information differing less than predetermined measurement errors from values that are based on the control values transmitted to the pattern pose and shape control element.

  • Patent number: 9915521
    Abstract: A method for scanning and obtaining three-dimensional (3D) coordinates is provided. The method includes providing a 3D measuring device having a projector, a first camera and a second camera. The method records images of a light pattern emitted by the projector onto an object.

  • Patent number: 9909855
    Abstract: A dimensional measuring device includes an overview camera and a triangulation scanner. A six-DOF tracking device tracks the dimensional measuring device as the triangulation scanner measures three-dimensional (3D) coordinates on an exterior of the object. Cardinal points identified by the overview camera are used to register in a common frame of reference 3D coordinates measured by the triangulation scanner on the interior and exterior of the object.

  • Patent number: 9858682
    Abstract: A device for optically scanning and measuring an environment is provided. The device includes at least one projector for producing at least one uncoded pattern on an object in the environment. A first camera is provided for recording at least one first image of the object provided with the pattern, the first camera having a first image plane. A second camera is provided for recording at least one second image of the object provided with the uncoded pattern, the second camera being spaced apart from the first camera in order to acquire the uncoded pattern on a second image plane.

  • Publication number: 20170332069
    Abstract: A device and method for scanning and measuring an environment is provided. The method includes providing a three-dimensional (3D) measurement device having a controller. Images of the environment are recorded and a 3D scan of the environment is produced with a three-dimensional point cloud. A first movement of the 3D measurement device is determined and then an operating parameter of the 3D measurement device is changed based at least in part on the first movement.
