Abstract: A system includes a three-dimensional (3D) scanner that captures a 3D point cloud corresponding to one or more objects in a surrounding environment. The system further includes a camera that captures a control image by capturing a plurality of images of the surrounding environment, and an auxiliary camera configured to capture an ultrawide-angle image of the surrounding environment. One or more processors of the system colorize the 3D point cloud using the ultrawide-angle image by mapping the ultrawide-angle image to the 3D point cloud. The system performs a limited system calibration before colorizing each 3D point cloud, and a periodic full system calibration before/after a plurality of 3D point clouds are colorized.

Abstract: A 3D measuring instrument includes a registration camera and a surface measuring system having a projector and autofocus camera. In a first pose, the registration camera captures a first registration image of first registration points. The autofocus camera captures a first surface image of first light projected onto the object by the projector and determines first 3D coordinates of points on the object. In a second pose, the registration camera captures a second registration image of second registration points. The autofocus camera adjusts the autofocus mechanism based at least in part on adjusting a focal length to reduce a difference between positions of the first and second registration points. A second surface image of second light is captured. A compensation parameter is determined based at least in part on the first registration image, the second registration image, the first 3D coordinates, the second surface image, and the projected second light.

Abstract: A method that includes providing a database for storing meta-data that describes steps in a workflow and an order of the steps in the workflow. The meta-data includes, for each of the steps: a reference to an input data file for the step; a description of a transaction performed at the step; and a reference to an output data file generated by the step based at least in part on applying the transaction to the input data file. Data that includes meta-data for a step in the workflow is received and the data is stored in the database. A trace of the workflow is generated based at least in part on contents of the database. The generating is based on receiving a request from a requestor for the trace of the workflow. At least a subset of the trace is output to the requestor.

Abstract: A system and method for measuring three-dimensional (3D) coordinates is provided. The method includes rotating a 3D scanner about a first axis, the 3D scanner having a light source, a light receiver and a color camera. A light beams are emitted from the light source and reflected light beams are received with the light receiver. A processor determines 3D coordinates of points on the object based on the emitted light beams and the reflected light beams. For each of the points an intensity value is measured based on the reflected light beams. A color image of the object is acquired with the color camera. The intensity values are fused with the color image to generate an enhanced image, the enhanced image includes color data. Color data is merged with the 3D coordinates of the points. The 3D coordinates of the points are stored with the color data.

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.
