3D object depth recovery from highlights using active sensor and illumination control

Two approaches for 3D curved object reconstruction using active sensor and illumination control are proposed and compared to each other. In both cases, the highlight information is fully utilized rather than discarded, and knowledge of the object surface is not required. The first approach requires camera control only and recovers shape (depth) from highlights and occluding contours. The second approach requires both camera and illumination control and recovers 3D depth from highlights only.
