A Novel Structured Light Pattern for One-Shot Shape Acquisition

This paper proposes a new one-shot grayscale structured lighting scheme to obtain depth data fast. Its key idea is to code the pattern using modulated sinusoidal gratings along two axes. The features used for matching are the fringe central lines of the vertical grating. The correlation of the intensity profiles is used to measure the similarity of features. Experimental results using a vision system with two cameras and a projector show that the proposed scheme is effective and efficient.
