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 system and method of determining three-dimensional coordinates is provided. The method includes, with a projector, projecting onto an object a projection pattern that includes collection of object spots. With a first camera, a first image is captured that includes first-image spots. With a second camera, a second image is captured that includes second-image spots. Each first-image spot is divided into first-image spot rows. Each second-image spot is divided into second-image spot rows. Central values are determined for each first-image and second-image spot row. A correspondence is determined among first-image and second-image spot rows, the corresponding first-image and second-image spot rows being a spot-row image pair. Tach spot-row image pair having a corresponding object spot row on the object. Three-dimensional (3D) coordinates of each object spot row are determined on the central values of the corresponding spot-row image pairs. The 3D coordinates of the object spot rows are stored.

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 description of an input data file for the step; a description of a transaction performed at the step; and a description of 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 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 laser scanner and method of operation to determine the consistency of a registration is provided. The method includes generating with the laser scanner at least a first scan of the scene with first measuring points. The laser scanner generates at least one second scan of the scene with second measuring points. At least one measured distance is determined from at least one of the second measuring points to the center of the second scan. The second scan is provisionally registered subjected to a consistency check. The consistency check is performed. At least one virtual distance is determined from at least one of the first measuring points to the center of the second scan. The consistency check is based at least in part on comparing the at least one virtual distance with the at least one measured distance.
