    Abstract: A triangulation scanner system and method of operation is provided. The system includes a projector that alternately projects a pattern of light and no light during first and second time intervals. A camera includes a lens and a circuit with a photosensitive array. The camera captures an image of an object. The photosensitive array has a plurality of pixels including a first pixel. The first pixel including an optical detector and a first and second accumulator. The optical detector produces signals in response to a light levels reflected from a point on the object. The first accumulator sums the signals during the first time intervals to obtain a first summed signal. The second accumulator sums the signals during the second time intervals obtain a second summed signal. A processor determines 3D coordinates of the point based on the projected pattern of light and on the first and second summed signals.

    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 photogrammetry system and method is provided. The photogrammetry system a two-dimensional (2D) camera operable to acquire a 2D image at a first resolution and a second resolution, and a 2D video image at the second resolution. A controller performs a method that includes acquiring a first 2D image of an object with the 2D camera at the first resolution. At least one feature on the object in the first 2D image. An image sequence is determined having a second position. A plurality of second 2D images are acquired with the 2D camera at the second resolution. The 2D camera is tracked. A direction of movement is indicated on the display. A third 2D image of the object is acquired when the 2D camera reaches the second position. Three-dimensional coordinates of the object are determined based on the first 2D image and the third 2D image.

    Abstract: A system and method for scanning an environment and generating an annotated 2D map is provided. The system includes a 2D scanner having a light source, an image sensor and a first controller. The first controller determines a distance value to at least one of the object points. The system further includes a 360° camera having a movable platform, and a second controller that merges the images acquired by the cameras to generate an image having a 360° view in a horizontal plane. The system also includes processors coupled to the 2D scanner and the 360° camera. The processors are responsive to generate a 2D map of the environment based at least in part on a signal from an operator and the distance value. The processors being further responsive for acquiring a 360° image and integrating it at a location on the 2D map.
