    Abstract: 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.

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

    Abstract: A noncontact optical three-dimensional measuring device that includes a projector, a first camera, and a second camera; a processor electrically coupled to the projector, the first camera and the second camera; and computer readable media which, when executed by the processor, causes the first digital signal to be collected at a first time and the second digital signal to be collected at a second time different than the first time and determines three-dimensional coordinates of a first point on the surface based at least in part on the first digital signal and the first distance and determines three-dimensional coordinates of a second point on the surface based at least in part on the second digital signal and the second distance.
