Recognition and Shape Recovery of a Solid of Revolution from a Single View Gray-Level Image under Perspective Projection
() Abstract
On the basis of the 3-D model of a solid of revolution, the geometric properties and algebraic formula of its limbs and cross-section curves under perspective projection are analyzed in detail. A new technique to recognize a solid of revolution and to extract its 3-D vision information from its a single viewgray-level image is successfully developed. Experiments have
demonstrated that the technique is exact, efficient and reliable.
Keywords
