Abstract

In the fields of computer vision and scene analysis, it is difficult to recognize a 3-dimensional object from 2-dimensional image taken by a TV camera, because the image changes as the object is rotated in 3-dimensional space. This paper deals with convex polyhedrons, and proposes a method for determining 2-dimensional visible patterns of a given 3-dimensional object. Each visible pattern is defined by the shapes of visible faces of the 3-dimensional object, and by the connection relationships between the faces. This method makes it easier to recognize a 3-dimensional object from 2-dimensional images. Finally we present some experimental results to show the effectiveness of our method.
