3D modeling and rendering from a single view

Description:

Recently the problem of interactive 3D reconstruction from a single view of a scene has attracted considerable attention. Such a reconstruction, without any knowledge of camera parameters, may find wide use in a variety of geometric modeling applications. 3D reconstruction from a single image must necessarily be through an interactive process, where the user provides information and constraints about the scene structure. Such information may be in terms of vanishing points or lines, co-planarity, spatial inter-relationship of features, and camera constraints. Here we assume the customary pin-hole camera model and present a method for 3D reconstruction from a single image based on the registration of two planes. The method is simple and intuitive and is applicable for structured scenes. The user needs to identify the two planes by clicking a rectangle on each. We show that the interactive registration of two planes facilitate 3D reconstruction of structured scenes using simple similar triangles and that it is also possible to recover the camera position and the internal parameters of the camera.
