Computing 3D models of rotating objects from moving shading

This work reconstructs 3D graphics model of an object from an image sequence taken during the object rotation. Shading and its motion information are used in estimating shapes of smooth surfaces between fixed edges from corners and patterns. Being different from conventional shape from shadings that...

Summary:This work reconstructs 3D graphics model of an object from an image sequence taken during the object rotation. Shading and its motion information are used in estimating shapes of smooth surfaces between fixed edges from corners and patterns. Being different from conventional shape from shadings that use one or several images, we use an image sequence that provides not only shading but also its motion. Maximum diffused shading moving on surfaces is followed at each rotation plane and surface normals are obtained. Positions of points are estimated from moving shading using motion stereo principle. It is linear equations directly achieving the results rather than iterative computation in shape from shading using complex approximation.
