Abstract

A device for scanning and obtaining three-dimensional coordinates is provided. The device may be a hand-held scanner that includes a carrying structure having a front and reverse side, the carrying structure having a first arm, a second arm and a third arm arranged in a T-shape or a Y-shape. A housing is coupled to the reverse side, a handle is positioned opposite the carrying structure, the housing and carrying structure defining an interior space. At least one projector is configured to project at least one pattern on an object, the projector being positioned within the interior space and oriented to project the at least one pattern from the front side. At least two cameras are provided spaced apart from each other, the cameras being configured to record images of the object. The cameras and projector are spaced apart from each other by a pre-determined distance.
