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...http://www.google.fr/patents/US5943164?utm_source=gb-gplus-shareBrevet US5943164 - Curved 3-D object description from single aerial images using shadows
