摘要： A trajectory generation method includes: obtaining distance information which a ranging apparatus has traveled; obtaining, from a sensor system, first angle information and second angle information corresponding to the ranging apparatus when the ranging apparatus is traveling in a space; determining a plurality of target sample points for a trajectory diagram of the space, and generating the trajectory diagram by connecting the plurality of target sampling points. Determining the target sample points includes: using a candidate sample point as one of the plurality of target sample points; in response to a trajectory adjustment condition not being satisfied, determining coordinates of the candidate sample point based on the distance information and the first angle information; and in response to the trajectory adjustment condition being satisfied, adjusting the candidate sample point based on the distance information, the first angle information, and the second angle information.

摘要： A three-dimensional measuring device includes a ball-shaped structure, an X-axis measuring module, a Y-axis measuring module and a Z-axis measuring module. The ball-shaped structure is moved and/or rotated in response to a movement of a movable object. The X-axis measuring module includes a first measuring structure and a first position sensor. The first measuring structure is movable along an X-axis direction and contacted with the ball-shaped structure. The Y-axis measuring module includes a second measuring structure and a second position sensor. The second measuring structure is movable along a Y-axis direction and contacted with the ball-shaped structure. The Z-axis measuring module includes a third measuring structure and a third position sensor. The third measuring structure is movable along a Z-axis direction and contacted with the ball-shaped structure.

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 and an apparatus for calibrating a tool in a flange coordinate system of a robot are disclosed. The method includes: acquiring a rotation angle of each joint of a robot when a to-be-calibrated tool fasted on an end joint mounting portion of the robot moves to a central point of the to-be-calibrated tool and overlaps with a calibration reference point; acquiring calibration information of a central point of a calibrated tool in a flange coordinate system of the robot; and completing calibration of the central point of the to-be-calibrated tool in the flange coordinate system of the robot according to the calibration information of the central point of the calibrated tool and a rotation angle of the to-be calibrated tool.

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.
