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 3D measurement system, a laser scanner and a measurement device are provided. The system includes a 3D measurement device and a 360 degree image acquisition system coupled in a fixed relationship to the 3D measurement device. The 360 degree image acquisition system includes a first photosensitive array operably coupled to a first lens, the first lens having a first optical axis in a first direction, the first lens being configured to provide a first field of view greater than 180 degrees. The image acquisition system further includes a second photosensitive array operably coupled to a second lens, the second lens having a second optical axis in a second direction, the second direction is opposite the first direction, the second lens being configured to provide a second field of view greater than 180 degrees. Wherein the first field of view at least partially overlaps with the second field of view.

Abstract: A three-dimensional (3D) measurement system, a method of measuring 3D coordinates, and a method of generating dense 3D data is provided. The method of measuring 3D coordinates includes using a first 3D measurement device and a second 3D measurement device in a cooperative manner is provided. The method includes acquiring a first set of 3D coordinates with the first 3D measurement device. The first set of 3D coordinates are transferred to the second 3D measurement device. A second set of 3D coordinates is acquired with the second 3D measurement device. The second set of 3D coordinates are registered to the first set of 3D coordinates in real-time while the second 3D measurement device is acquiring the second set of 3D coordinates.

Abstract: A three-dimensional (3D) scanner includes a light source, an optical detector, a reference reflector, and a 3D aperture structure having side walls and an aperture, the aperture sized to pass a first portion of the light reflected by the reference reflector, the side walls sized to block a second portion of the light reflected by the reference reflector. The 3D scanner further includes a tilted optical bandpass filter to block ambient background light without creating cavity reflections that might cause errors in measured distance.

Abstract: A system and method for measuring three-dimensional (3D) coordinate values of an environment is provided. The system includes a movable base unit and a 2D scanner. A 3D scanner is coupled to the base unit, the 3D scanner measuring 3D coordinates and grey values of surfaces in the environment, the 3D scanner operating in either a compound or helical mode. Processors perform a method comprising: causing the 3D scanner to measure a first 3D coordinate values while operating in one of the compound or helical mode as the base unit is moved from the first to the second position; causing the 3D scanner to measure a second 3D coordinate values while operating in compound mode when the base unit is stationary between the first and second position; and registering the first 3D coordinate values and second 3D coordinate values into a single frame of reference.
