    摘要: A 3D measurement system, a laser scanner and a measurement device are provided. The system includes a 3D measurement device and a 360 degree image acquisition system coupled in a fixed relationship to the 3D measurement device. The 360 degree image acquisition system includes a first photosensitive array operably coupled to a first lens, the first lens having a first optical axis in a first direction, the first lens being configured to provide a first field of view greater than 180 degrees. The image acquisition system further includes a second photosensitive array operably coupled to a second lens, the second lens having a second optical axis in a second direction, the second direction is opposite the first direction, the second lens being configured to provide a second field of view greater than 180 degrees. Wherein the first field of view at least partially overlaps with the second field of view.

    摘要: A noncontact optical three-dimensional measuring device that includes a first projector, a first camera, and a second camera; a processor electrically coupled to the first 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 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 signal.

    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.
