Examples described herein provide a method that includes capturing data about an environment. The method further includes generating a database of two-dimensional (2D) features and associated three-dimensional (3D) coordinates based at least in part on the data about the environment. The method further includes determining a position (x, y, z) and an orientation (pitch, roll, yaw) of a device within the environment based at least in part on the database of 2D features and associated 3D coordinates. The method further includes causing the device to display, on a display of the device, an augmented reality element at a predetermined location based at least in part on the position and the orientation of the device.

Tracking with reference to a world coordinate system

A coordinate measuring device is provided having a light source that emits a beam of light. A distance meter measures a distance to a target. A first locator camera assembly includes a first camera and first lights. A second locator camera assembly includes a second camera and second lights. The processor matches retroreflectors in a first image of the first camera and a second image of the second camera based on a shape-and-context matching of retroreflector spots in the first and second image and on an area-context-matching of background objects in the first and second image. The retroreflector spots in the first image produced by illumination of the retroreflectors by the first lights, the retroreflector spots in the second image produced by illumination of the retroreflectors by the second lights. The processor provides a third image that includes both the background objects and markers indicating the matched retroreflectors.

Three-dimensional coordinate measuring device

A three-dimensional (3D) coordinate measurement device and method of operating combines tracker and scanner functionality. The method includes selecting an operating mode on the coordinate measurement device. A first light is emitted from the coordinate measurement device. At least two angles associated with the emitting of the first light are measured. A second light is received with an optical detector, wherein the second light is a reflection of the first light off of the retroreflector or the surface. A distance is determined based at least in part on the selected mode, the emitting of the first light, and the receiving of the second light. Three dimensional coordinates of at least one point in the environment are determined based at least in part on the measuring of the at least two angles and the determination of the distance.

Method of operating a coordinate measurement device

A dimensional measuring device includes an overview camera and a triangulation scanner. A six-DOF tracking device tracks the dimensional measuring device as the triangulation scanner measures three-dimensional (3D) coordinates on an exterior of the object. Cardinal points identified by the overview camera are used to register in a common frame of reference 3D coordinates measured by the triangulation scanner on the interior and exterior of the object.

Registration of three-dimensional coordinates measured on interior and exterior portions of an object

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.

Combination scanner and tracker device having a focusing mechanism

A triangulation scanner having an enclosure, a projector coupled to the enclosure and configured to emit a first light, and three cameras also coupled to the enclosure. The scanner further includes at least one processor to determine the three-dimensional coordinates in a local frame of reference based at least in part on receiving the first light.

Triangulation scanner with blue-light projector

A three-dimensional (3D) scanner having two cameras and a projector is detachably coupled to a device selected from the group consisting of: an articulated arm coordinate measuring machine, a camera assembly, a six degree-of-freedom (six-DOF) tracker target assembly, and a six-DOF light point target assembly.

Two-camera triangulation scanner with detachable coupling mechanism

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.

Three-dimensional coordinates of two-dimensional edge lines obtained with a tracker camera

A method for verifying performance of a light projector includes establishing a reference artifact that include reflective makers and an interior edge line, determining with a laser-tracker-based three-dimensional (3D) measuring system 3D coordinates of the reflective targets and the interior edge line, determining with the light projector angles to the reflective markers with the light projector, and projecting with the light projector a pattern of light onto the interior edge line.

System and method for verifying projection accuracy

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.

Augmented reality camera for use with 3D metrology equipment in forming 3D images from 2D camera images

An apparatus includes a kinematic nest that supports an element having a spherical surface, a rotation mechanism that rotates the element, and processor that activates the rotation mechanism.

Automated rotation mechanism for spherically mounted retroreflector

A tracker includes a retro-follow mode that causes a beam of light from the tracker to follow a retroreflector while locked onto the retroreflector with the beam of light turned on or, alternatively, using target cameras with the beam of light turned off.

Retroreflector acquisition in a coordinate measuring device

A noncontact optical three-dimensional measuring device that includes a projector and a camera; a processor electrically coupled to the projector and the camera; and computer readable media which, when executed by the processor, causes the first signal to be collected at a first time and the second signal to be collected at a second time different than the first time and determines three-dimensional coordinates of a first point on the surface based at least in part on the first signal and the distance and determines three-dimensional coordinates of a second point on the surface based at least in part on the second signal and the distance.
