Abstract

3D measurement is one of the most important topic in computer vision,which be used to recover object surface. Using a calibrated projector-camera pair, a light pattern is projected onto the scene and imaged by the cameras. Since the pattern is coded,correspondences between image points and points of the projected pattern can be easily found.These correspondences are used to triangulate and extract 3D information of the surface. Dense reconstruction can be obtained when combining traditional binary codes with phase shifting techniques, where the same pattern is projected and shifted several times. From phase deviation is possible to extract height of the object, given the distance to a reference plane and calibration parameters.
