Abstract

A creation of simulation scenes from a specified view point is provided. The method consists in obtaining digital photographic images of the scene from the specified view point, detecting objects in the digital photographic images, extracting masks of the object, and associating a distance to the digital photographic image, and a lower distance to the object. The scene thus created provides a photorealistic scene wherein 3D objects can be inserted. According to the distances of the 3D objects, they can be displayed behind or beyond the masks, but always behind the digital photographic images that defines the background of the scene.
