Rapid and automatic optimal exposure control for digital fringe projection technique

The proposed method only requires capture fringe image(s) with one exposure time to automatically determine the global optimal exposure time for high-quality 3D shape measurement; and the authors further propose to automatically achieve high-dynamic range (HDR) 3D shape measurement by capture image(s) with the optimized global single exposure. Experimental results demonstrated the proposed method can work on a static complex scene and can also be applicable for real-time applications. (publisher abstract modified)
