Abstract: A laser scanner includes a light emitter that generates a modulated light beam for measuring distance and red, blue, and green lights for capturing colors. The beam is collimated and directed to an object point with a steering mirror. Reflected light from the object point is directed by the steering mirror onto scanner optics. The reflected light is directed to an optical receiver that sends the first light in a first path and the second, third and fourth lights in a second path to a color receiver. The first light is demodulated to determine distance to the target. The second, third, and fourth lights are separated and measured to determine three color values. The color values are combined with the measured distance value to determine a color 3D coordinate for the object point.

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. A 2D scanner collects horizontal 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 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.

Abstract: A method and system for inspecting an object is provided. The system includes a measurement device that measures 3D coordinates of points on a surface of the object. A display is coupled to the device and is sized to be carried by an operator. One or more processors cooperate with the measurement device, to perform a method comprising: determining 3D coordinates of the points while the object is being measured; aligning an electronic model of the object to the points while the object is being measured; determining a variance between the electronic model and the points while the object is being measured; and displaying on the display an indicator when the variance exceeds a threshold while the object is being measured.

Abstract: A method for optically scanning and measuring an environment using a 3D measurement device is provided. The method includes steps that are performed prior to operation. These steps include positioning a near-field communication (NFC) device adjacent the 3D measurement device. An NFC link is established between the NFC device and the 3D measurement device. An identifier is transmitted from the NFC device to the 3D measurement device. It is determined that the NFC device is authorized to communicate with the 3D measurement device based at least in part on the identifier. Commands are transferred to the 3D measurement device from the NFC device based at least in part on determining the first NFC device is authorized. At least one communication path is activated. The 3D measurement device is connected to a network of computers and measurement data is transmitted from the 3D measurement device to the network of computers.

Abstract: A method interactively displays panoramic images of a scene. The method includes measuring 3D coordinates 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.
