    Abstract: A triangulation scanner system and method of operation is provided. The system includes a projector that projects a first pattern of light at a first light level during first time intervals and project the first pattern of light at a second light level during second time intervals, the second light level being different than the first light level. A first camera has a first photosensitive array, the first photosensitive array having a first pixel with an optical detector, a first memory, and a second memory. The first memory storing a first stored signal from the optical detector during the first time intervals, the second memory storing a second signal from the optical detector during the second time intervals. A processor determines three-dimensional coordinates of the first point based at least in part on the projected first pattern of light, the first stored signal, and the second stored signal.

    Abstract: A method for optically scanning and measuring an environment by means of a hand-held scanner for producing 3D-scans is provided. The method including providing a hand-held scanner having at least one projector and at least one camera. At least one pattern is projected onto an object in the environment with the at least one projector. At least one camera images of the object which has the pattern projected thereon is recorded with a plurality of frames. Three-dimensional coordinates of points on the surface of the object are determined from each frame in the plurality of frames. A ring closure is determined in the plurality of frames. The determination comprising the steps of forming a frustum for each frame, comparing a last frustum of the last frame with a plurality of frusta to form an intersection, and selecting a frustum having the largest intersection.

    Abstract: According to one or more embodiments, a system includes a scanner device configured to capture a set of point clouds comprising 3D points. The system further includes one or more processors that detect, during the capture of the set of point clouds, at least one first anchor object in a first part of a first point cloud. The first part belongs to a first time interval centered at time t1. A second anchor object is detected in a second part of the first point cloud, the second part belonging to second time interval centered at time t2. Further, at least one correspondence is identified between the first anchor object and the second anchor object. The first part of the first point cloud is aligned with the second part of the first point cloud based on the at least one correspondence between the first anchor object and the second anchor object.
