A hand-held approach to 3D reconstruction using light stripe projections onto a cube frame

The current paper presents a new light-striping approach for reconstructing a 3D model from a real object. The proposed system consists of a light plane projector, camera, and cube frame with LEDs attached. Instead of a strictly controlled camera and light emitters, a freely movable hand-held device is used that enables one to scan self-occluded objects. As in other light-striping systems, the correspondence problem is solved by projecting a light plane onto an object inside a frame. In the proposed system, the 3D coordinates of an illuminated light stripe are obtained using a calibration-free approach or dynamic optical triangulation. Furthermore, the computed 3D point data does not require any registration process because the data is directly measured based on unified world coordinates. Experimental results proved the accuracy of the measurements and consistency of the outcomes without any knowledge of the camera and light source parameters.
