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

According to some aspects of the invention, auxiliary axis measurement systems for determining three-dimensional coordinates of an object are provided as shown and described herein. According to some aspects of the invention, methods for operating auxiliary axis measurement systems for determining three-dimensional coordinates of an object are provided as shown and described herein.

Coordinate measurement system with auxiliary axis

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

Securing data acquired by coordinate measurement devices including receiving a request from a requestor to access a data file including data that was acquired by a coordinate measurement device. The data file is retrieved and the content of the data file is authenticated. The authenticating includes retrieving an expected digital security attribute previously calculated by a digital security function based on content of the data file prior to the data file being retrieved. The authenticating also includes applying the digital security function to the data file to calculate an actual digital security attribute, and comparing the expected digital security attribute to the actual digital security attribute. Based on the comparing, a value of valid or not valid is assigned to an output of the authenticating.

Securing data acquired by coordinate measurement devices

A method and system for acquiring three-dimensional (3D) coordinates of a surface is provided. The method includes providing the scanner configured to emit a light from the light source and reflect the light onto the surface, the scanner further being configured to determine with a processor a three-dimensional coordinate of a point on the surface based at least in part on a first and second angle measuring device and a reflection of the light from the surface. An image is acquired of the surface with a camera and a feature is identified. A first area is identified having a high information content and a first arc segment is determined. The surface is scanned by rotating a motor at a first speed during the first arc segment and at a second speed during a second arc segment, the second speed being greater than the first speed.

Laser scanner

A spherically mounted retroreflector (SMR) includes a substrate, an optic, and an adhesive. The substrate has a partially spherical outer surface and a cavity, the partially spherical outer surface has a sphere center. The optic has a cube-corner retroreflector fixedly disposed within the cavity; the cube-corner retroreflector has an optical vertex. The adhesive is disposed between the optic and the substrate and fixedly adheres the optic to the substrate. The optical vertex is coincident with the sphere center. The substrate is made from a ferromagnetic material and has an electroless nickel outer coating.

A target is provided having a retroreflector. A body is provided having a spherical exterior portion, the body containing a cavity. The cavity is sized to hold the retroreflector, the cavity open to the exterior of the body and having at least one surface opposite the opening, the retroreflector at least partially disposed in the cavity, wherein the retroreflector and at least one surface define a space therebetween. A transmitter is configured to emit an electromagnetic signal. A first actuator is configured to initiate emission of the electromagnetic signal, wherein the transmitter and the first actuator are affixed to the body.

A method of dynamically adjusting an angular speed of a light beam emitted by a scanner in measuring three-dimensional (3D) coordinates of a surface or of dynamically adjusting an acquisition rate of 3D coordinates of a surface.

Measuring with a system having retroreflector targets and a laser tracker includes storing a list of coordinates for three targets and at least one added point; capturing on a photosensitive array a portion of the light emitted by a light beam and reflected off the targets; obtaining spot positions on a photosensitive array of a tracker camera from the reflected light; determining a correspondence between three spot positions on the photosensitive array and the coordinates of the targets; directing a beam of light from the tracker to the targets based at least in part on the coordinates of the first target and the first spot position; measuring 3-D coordinates of the targets with the tracker; determining 3-D coordinates of the at least one added point based at least in part on the measured 3-D coordinates of the targets and the coordinates of the at least one added point.
