Abstract: A three-dimensional (3D) coordinate measurement device combines tracker and scanner functionality. The tracker function is configured to send light to a retroreflector and determine distance to the retroreflector based on the reflected light. The tracker is also configured to track the retroreflector as it moves, and to determine 3D coordinates of the retroreflector. The scanner is configured to send a beam of light to a point on an object surface and to determine 3D coordinate of the point. In addition, the scanner is configured to adjustably focus the beam of light.

Abstract: A method and system for scanning and measuring an environment is provided. The method includes providing a first three-dimensional (3D) measurement device. The 3D measurement device being operable in a helical mode or a compound mode, wherein a plurality of light beams are emitted along a first path defined by a first axis and a second axis in the compound mode and along a second path defined by the first axis in the helical mode. A mobile platform holding the 3D measurement device is moved from a first position. A first group of 3D coordinates of the area is acquired by the 3D measurement device when the mobile platform is moving. A second group of 3D coordinates of the area is acquired with a second 3D measurement device that with six-degrees of freedom (6DOF). The first group of 3D coordinates is registered based on the third group of 3D coordinates.

Abstract: Individual bug fixed messages for software users that includes determining an occurrence of an error in software executing on a user processor. A unique error report identifier is stored in a memory accessible by the user processor and the error is reported. The reporting includes transmitting the unique error report identifier and error data that describes the error to a developer server. The error data is analyzed to determine a fix to correct the error. A message regarding the fix to correct the error is stored in a fixed error database. The software is launched and it is determined that the error was previously reported. The fixed error database is queried by the software with the unique error report identifier to locate the message. Based on locating the message, the message is downloaded and displayed by the user processor.

Abstract: At each of three different locations, a tracker captures a 2D image an object and measures three points in space at each of three tracker locations relative to the object. Based on this information, the tracker determines, in an object frame of reference, three-dimensional coordinates of an arbitrary point on an edge line common to the three 2D images.

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 system and method for analyzing a surface of an object is provided. The system includes a 3D measurement device operable to acquire a plurality of points on the surface of the object and determine 3D coordinates for each of the points. The system further includes processors operably coupled to the 3D measurement device. The processors are responsive to computer instructions when executed on the processors for performing a method comprising: generating a point cloud from the 3D coordinates of the plurality of points; extracting a first set of points from the plurality of points; defining a first reference geometry through the first set of points; measuring at least one first metric from each of the points in the first set of points to the first reference geometry; and identifying a nonconforming feature based at least in part on the at least one first metric.

Abstract: A method for optically communicating, from a user to a laser tracker, a command to direct a beam of light from the laser tracker to a retroreflector with steps including: projecting a first light from a light source disposed on the laser tracker to the retroreflector; reflecting a second light from the retroreflector, the second light being a portion of the first light; obtaining first sensed data by sensing a third light, the third light being a portion of the second light, wherein the first sensed data is obtained by imaging the third light onto a photosensitive array disposed on the laser tracker and converting the third light on the photosensitive array into digital form; generating by the user, between a first time and a second time, a predefined temporal pattern, the predefined temporal pattern including at least a decrease in optical power of the third light followed by an increase in the optical power of the third light, the predefined temporal pattern corresponding to the command; determining by the laser tracker that the first sensed data corresponds to the predefined temporal pattern; and, pointing the beam of light from the laser tracker to the retroreflector.

Abstract: A method uses a two-dimensional (2D) camera in two different positions to provide first and second 2D images having three common cardinal points. It further uses a three-dimensional (3D) measuring device to measure two 3D coordinates. The first and second 2D images and the two 3D coordinates are combined to obtain a scaled 3D image.

Abstract: An articulated arm coordinate measurement machine is provided with a configurable arm bus. The arm bus being comprised of a plurality of busses that may be selectively coupled to form one or more logical data communications busses. The logical busses may be configured to allow accessory devices to be coupled to the arm and transmit data at higher speeds and at lower costs than may be possible using data busses having fixed communications protocols. In one embodiment, one or more communications switches may be arranged in the probe end of the arm to selectively combine the busses into a logical bus.
