ABSTRACT:
This is a system and method of describing 3-D objects from single aerial images using shadows. The method may include using object shadow information to extract generalized cone description (sweep rule, cross-section and axis). Additionally, this generalized cone information may then be used to reconstruct a 3-D object. The method may model curved 3-D objects, such as curved buildings, cooling towers, chimneys and oil tanks in aerial images, as generalized cones.
