Abstract: A portable articulated arm coordinate measuring machine (AACMM) having an integrated camera captures 2D images of an object at three or more different poses. A processor determines 3D coordinates of a smoothly continuous edge point of the object based at least in part on the captured 2D images and pose data provided by the AACMM.

Abstract: 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.

Abstract: A method and system are provided for controlling a measurement device remotely through gestures performed by a user. The method includes providing a relationship between each of a plurality of commands and each of a plurality of user gestures. A gesture is performed by the user with the user's body that corresponds to one of the plurality of user gestures. The gesture performed by the user is detected. A first command is determined from one of the plurality of commands based at least in part on the detected gesture. Then the first command is executed with the laser tracker.

Abstract: A line scanner measures 3D coordinates of an object surface and includes a projector with a light source that projects a line of light at the object surface. The line scanner also has a camera with a 2D array of light sensors and electronics that controls the exposure and readout times of each light sensor, the exposure time being controlled in either rows or columns of the array in a non-sequential manner, the readout time being controlled in either rows or columns that are the same as the rows or columns whose exposure time is being controlled, each of the light sensors converts an amount of captured optical energy into a digital signal value, the captured optical energy being from a reflected line of light from the object surface. Further includes a processor that receives the digital signal values and calculates the 3D coordinates of the object surface.

Abstract: A method of combining 2D images into a 3D image includes providing a coordinate measurement device and a triangulation scanner having an integral camera associated therewith, the scanner being separate from the coordinate measurement device. In a first instance, the coordinate measurement device determines the position and orientation of the scanner and the integral camera captures a first 2D image. In a second instance, the scanner is moved, the coordinate measurement device determines the position and orientation of the scanner, and the integral camera captures a second 2D image. A cardinal point common to the first and second images is found and is used, together with the first and second images and the positions and orientations of the scanner in the first and second instances, to create the 3D image.

Abstract: A portable articulated arm coordinate measuring machine includes a noncontact 3D measuring device that has a projector that is manually movable by an operator from a first position to a second position. The projector is configured to emit a first pattern of light onto an object. The noncontact 3D measuring device further includes a scanner camera and an edge-detecting camera. The scanner camera is arranged to receive the first pattern of light reflected from the surface of the object. The edge-detecting camera arranged to receive light reflected from an edge feature of the object. The articulated arm coordinate measurement machine includes a processor configured to determine first 3D coordinates of an edge point of the edge feature based on electrical signals received from the scanner camera and the edge-detecting camera.
