    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: A system and method for determining a distance is provided. The system includes a scanner that captures a scan-point by emitting a light having a base frequency and at least one measurement frequency and receiving a reflection of the light. Processors determine the distance to the scan-point by using a method that comprises: generating a signal in response to receiving the reflection of light; determining a first distance to the scan-point based on a phase-shift of the signal and the measurement frequency; determining a second distance and a third distance based on a phase-shift of the signal determined using a Fourier transform at the measurement frequency on a pair of adjacent half-cycles; determining a corrected second distance and a corrected third distance by compensating for an error in the second distance and third distance by performing the Fourier transform on the pair of adjacent half-cycles.

    Abstract: A three-dimensional (3D) measurement system, a method of measuring 3D coordinates, and a method of generating dense 3D data is provided. The method of measuring 3D coordinates includes using a first 3D measurement device and a second 3D measurement device in a cooperative manner is provided. The method includes acquiring a first set of 3D coordinates with the first 3D measurement device. The first set of 3D coordinates are transferred to the second 3D measurement device. A second set of 3D coordinates is acquired with the second 3D measurement device. The second set of 3D coordinates are registered to the first set of 3D coordinates in real-time while the second 3D measurement device is acquiring the second set of 3D coordinates.

    Abstract: A three-dimensional (3D) measuring instrument includes a registration camera and a surface measuring system having a projector and an autofocus camera. For the instrument in a first pose, the registration camera captures a first registration image of first registration points. The autofocus camera captures a first surface image of first light projected onto the object by the projector and determines first 3D coordinates of points on the object. For the instrument in a second pose, the registration camera captures a second registration image of second registration points. The autofocus camera adjusts the autofocus mechanism and captures a second surface image of second light projected by the projector. A compensation parameter is determined based at least in part on the first registration image, the second registration image, the first 3D coordinates, the second surface image, and the projected second light.

    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.
