Abstract:
A method for measuring and registering 3D coordinates has a 3D scanner measure a first collection of 3D coordinates of points from a first registration position and a second collection of 3D coordinates of points from a second registration position. In between these positions, the 3D scanner collects 2D camera images. A processor determines first and second translation values and a first rotation value based on the 2D camera images. The processor adjusts the second collection of points relative to the first collection of points based at least in part on the first and second translation values and the first rotation value. The processor identifies a correspondence among registration targets in the first and second collection of 3D coordinates, and uses this correspondence to further adjust the relative position and orientation of the first and second collection of 3D coordinates.
Abstract:
A method for scanning and measuring using a 3D measurement device is provided. The method includes providing the 3D measurement device having a light emitter, a light receiver and a command and evaluation device. The 3D measurement device is further includes a first near-field communication (NFC) device having a first antenna. A second NFC device having a second antenna is positioned adjacent the 3D measurement device. An NFC link is established between the first NFC device and the 3D measurement device. An identifier is transmitted from the second NFC device to the 3D measurement device. It is determined that the second NFC device is authorized to communicate with the 3D measurement device. Commands are transferred to the 3D measurement device from the second NFC device based at least in part on the determination that the second NFC device is authorized to communicate with the 3D measurement device.
Abstract:
A method interactively displays panoramic images of a scene. The method includes measuring 3D coordinates of the scene with a 3D measuring instrument at a first position and a second position. The 3D coordinates are registering into a common frame of reference. Within the scene, a trajectory includes a plurality of trajectory points. Along the trajectory, 2D images are generated from the commonly registered 3D coordinates. A trajectory display mode sequentially displays a collection of 2D images at the trajectory points. A rotational display mode allows a user to select a desired view direction at a given trajectory point. The user selects the trajectory display mode or the rotational display mode and sees the result shown on the display device.

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. A controller is provided having a processor configured to determine the three-dimensional coordinates of points on the surface of the object based at least in part on the uncoded pattern, the at least one first image and the at least one second image.

Abstract:
A method for measuring and registering 3D coordinates has a 3D scanner measure a first collection of 3D coordinates of points from a first registration position. The 3D scanner collects 2D scan sets as 3D measuring device moves from first to second registration positions. A processor determines first and second translation values and a first rotation value based on collected 2D scan sets. 3D scanner measures a second collection of 3D coordinates of points from second registration position. Processor adjusts the second collection of points relative to first collection of points based at least in part on first and second translation values and first rotation value. Processor identifies a correspondence among registration targets in first and second collection of 3D coordinates, and uses this correspondence to further adjust the relative position and orientation of first and second collection of 3D coordinates.
