Resumen en inglés

Augmented Reality (AR) aims to provide means to integrate virtual objects in a real scene. In that context it is often necessary to recover geometrical information such as objects shapes from the scene in order to add new objects. This paper proposes a semiautomatic method to reconstruct the surface of the ocean from a real ocean scene. A detection algorithm is applied to identify significant waves crestlines. A virtual ocean is then reconstructed using Gerstner model; its parameters are inferred and adjusted by the user to match the crestlines and to provide a smooth reconstruction between adjacent waves. An application is presented to insert a virtual object in the real ocean scene that computes correct occlusions between the ocean surface and the object and uses OpenGL for real-time rendering< Leer menos
