Abstract:
A digitizer combining functions of stereovision, color 3D digitizing and motion capture of a target object, comprising:a first camera; a second camera; a first projection arrangement having a first light projector providing lighting for an active 3D range sensing for each of the cameras, and a grating element in front of the first light projector for projection of an encoded pattern on a surface of the target object; a second projection arrangement having a second light projector providing lighting for an acquisition of texture information of the target object; a base onto which the first and second cameras and the first and second projection arrangements are mounted in fixed relative positions with respect to one another, the cameras having optical axes converging through a single point, one of the light projectors having an optical axis intersecting with the optical axes of the cameras at the single point; and a communication port connected to the cameras and the light projectors, for reception of control signals setting operation of the cameras and the light projectors and transmission of video signals from the cameras.
