Constructing 3-D Object Models Using Multiple Simulated 2.5-D Sketches

Abstract Many applications involve the construction of 3-D object models from which images, often requiring a high degree of realism, are later produced. Constructing such models frequently involves considerable human intervention, even in cases where a physical model or the actual object to be modelled exists. This paper describes an approach to the automatic construction of 3-D object models using images of scenes. This method employs a representation of the visible surfaces in a scene called the 2.5-D sketch and a model construction process is described that utilizes multiple simulated 2.5-D sketches.
