| Popis: | Generally, extraction of boundary lines from a binocular stereo image is effective for a plane with patterns or a curved surface with shadows, and a place with uniform surface. Since a uniform plain cannot directly be reconstructed, however, another process to reconstruct the plain is needed after its boundary line is reconstructed. If a simple algorithm is applied to this process, a false plane is extracted sometimes. This paper describes a method uniquely to determine a plane from the three-dimensional boundary lines of an object in the stereo image. The method is effective for any object consisting of planes in the image. The method can also locally detect a fault in the boundary line so that this makes its compensation process easy. The final output image of this method is available in a form of a ‘geometrical mode’. |
