摘要： 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.

摘要： A method for scanning and obtaining three-dimensional (3D)l coordinates is provided. The method includes providing a 3D measuring device having a projector, a first camera and a second camera. The method records images of a light pattern emitted by the projector onto an object. A deviation in a measured parameter from an expected parameter is determined. The calibration of the 3D measuring device may be changed when the deviation is outside of a predetermined threshold.

摘要： A method is provided of determining three-dimensional coordinates of an object surface with a laser tracker and structured light scanner. The method includes providing the scanner having a body, a pair of cameras, a projector, and a processor. The projector and cameras are positioned in a non-collinear arrangement. The projector is configured to project a first pattern onto the surface. The method also includes providing the tracker which emits a beam of light onto the retroreflector. The tracker receives a reflected beam of light. The first location is measured with the tracker. The first orientation is measured with the tracker. The first surface pattern is projected onto the surface. A pair of images of the surface pattern is acquired with cameras. The processor determines the 3D coordinates of a first plurality of points in the tracker frame of reference based in part on epipolar constraints of the cameras and projector.

摘要： A device for scanning and obtaining three-dimensional coordinates is provided. The device may be a hand-held scanner that includes a carrying structure having a front and reverse side, the carrying structure having a first arm, a second arm and a third arm arranged in a T-shape or a Y-shape. A housing is coupled to the reverse side, a handle is positioned opposite the carrying structure, the housing and carrying structure defining an interior space. At least one projector is configured to project at least one pattern on an object, the projector being positioned within the interior space and oriented to project the at least one pattern from the front side. At least two cameras are provided spaced apart from each other, the cameras being configured to record images of the object. The cameras and projector are spaced apart from each other by a pre-determined distance.

摘要： A method for measuring 3D coordinates of points on a surface of an object by providing an articulated arm connected to a laser line probe. The laser line probe having a color camera sends color images to a processor, which determines 3D surface coordinates using triangulation. The processor weights each of the colors received from the pixels to enable dark and bright regions of the surface to be measured simultaneously.

摘要： A system measuring an object with a human-centric robot is provided. The robot including a movable end effector having a coupler, the robot including a plurality of transducers arranged to transmit signals to an electronic circuit, the electronic circuit configured in operation to determine the position and orientation of the end effector. At least one tool is provided having a first gripping portion, the gripping portion being sized and shaped to removably couple to the coupler. A three-dimensional (3D) scanner is provided that is configured in operation to determine three-dimensional coordinates of a surface of an object, the 3D scanner having a second gripping portion sized and shaped to removably couple to the coupler. A controller is configured to selectively couple one of the at least one tool or the 3D scanner to the coupler in response to an object signal.

摘要： A device for optically scanning and measuring an environment is provided. The device includes at least one projector for producing at least one uncoded pattern on an object in the environment. A first camera is provided for recording at least one first image of the object provided with the pattern, the first camera having a first image plane. A second camera is provided for recording at least one second image of the object provided with the uncoded pattern, the second camera being spaced apart from the first camera in order to acquire the uncoded pattern on a second image plane.
