A new approach of recovering 3-D shape from structure-lighting

This paper presents a new approach to recover 3-D shape from only one simple structured-lighting image without knowing any information about the surface of the object and the structured-lighting system. Analysis of a structured-lighting image can estimate the calibration parameters of the system including the focal length of the camera and the position of the grating. Without any corresponding, the approach, has been applied to recover rather complicated 3-D shape in a varied environment.
