The main goals of Computer Vision are the recovery of
the three dimensional structure and the recognition of
viewed objects from T.V. images. The understanding of
images of indoor scenes, such as corridors and offices, is
greatly simplified by the exploration of geometrical properties
of the viewed scene. In these scenes there are many
long straight edges which are either parallel or orthogonal
and the viewed objects can be modeled as elements
of Legoland. Legoland is a block world where physical
edges have at most three directions, which are mutually
orthogonal.
In this paper a general procedure is proposed for the understanding
of indoor scenes which is likely to be useful
in Computer Vision. The proposed algorithm makes use
of an extensive 2D image processing which is able to provide
a faithful line drawing of the viewed scene. It also
uses procedures adequate for both the understanding of
the 3D structure of the viewed scene and for the recognition
of several items in the scene.
