摘要： 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.

摘要： A sensor adjustment mechanism for a coordinate measuring machine includes a sensor, first and second joints, a change interface, and a fixing device. The first joint allows the sensor to pivot about a first axis. The second joint allows the sensor to rotate about a second axis. The change interface releasably couples the sensor adjustment mechanism to a measuring head of the coordinate measuring machine. The fixing device is configured to clamp the joints. The change interface includes a first component and a ferromagnetic second component movable relative to the first component. The change interface is configured to be fixed to the measuring head by a magnetic fixing force exerted on the second component, which causes a movement of the second component relative to the first component. The movement actuates the fixing device so as to clamp the joints and inhibit the sensor from being pivotable and rotatable.

摘要： An example of a controller calculates the orientation of the controller based on an output from an inertial sensor, and when a value representing the calculated orientation satisfies a first condition, compresses data in a mode 2, and when the first condition is not satisfied, but a second condition is satisfied, compresses the data in a mode 1, and when the second condition is not satisfied, compresses the data in a mode 0. Then, the controller transmits the compressed data to another apparatus.

摘要： 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.

摘要： The invention provides a method for measuring a slant wall thickness of a hub. Specifically, the hub is laid flatwise on a detection platform of a three-coordinate measuring machine; afterwards, a first inner wall point 1 and a second inner wall point 2 are sampled from an inner rim slant of the hub along a YZ axial section of the three-coordinate measuring machine, and X-axis coordinate values of the two points are set to zero to establish a first Cartesian coordinate system; the two points defined in step 101 are connected and configured into an axial line of a rim wall thickness; a second Cartesian coordinate system is established with a direction of the axial line of the rim wall thickness as a Y′ axis; an inner rim wall thickness point 3 from an inner rim wall, and an outer rim wall thickness point 4, both having X′ values of zero, are sampled; a two-dimensional distance between the inner rim wall thickness point 3 and the outer rim wall thickness point 4 in a Z′ axis is calculated under the second coordinate system and recorded as a measured slant wall thickness value of the hub. The method provided by the present invention has the advantages of avoiding the situation that the three-coordinate measuring machine has a large error in measuring a rim wall thickness due to the use of the detection platform as a benchmark, improving the accuracy of detection, and providing the basis of automated rim thickness detection.

摘要： A system and method of determining 3D coordinates of an object is provided. The method includes determining a first set of 3D coordinates for a plurality of points on the object with a structured light scanner. An inspection plan is determined for the object, which includes features to be inspected with a remote probe. The points are mapped onto a CAD model. The features are identified on the plurality of points mapped onto a CAD model. A visible light is projected with the scanner proximate a first feature of the features. A sensor is contacted on the remote probe to at least one first point on the first feature on the object. A first position and orientation of the remote probe are determined with the scanner. A second set of 3D coordinates of the at least one first point are determined on the first feature on the object.

摘要： A recess or “pocket” is formed in at least one leg of a moving bridge assembly of a coordinate measuring machine, and in a particular embodiment in a primary leg of a moving bridge assembly, to permit a quill to move farther in the X direction to an end of a planar base surface of the coordinate measuring machine adjacent the leg without interfering with the leg. The recess formed in the leg of the moving bridge assembly permits coordinate measurements of a part whose width covers the full area of the planar surface of the base, without necessarily adding significant cost or increasing the footprint of the measurement system.
