<p>A system for the automatic recognition of parallel lines in a perspective image of a viewed object (8) comprises a recognition system (7) which detects edge lines of the image and recognises as parallel lines those lines which have a common vanishing direction (17). An algorithm generates a set of planes (14, 15, 16) for the image lines, together with a set of initial pairings between these lines. The quality of fit is decided by the deviation of the end points of the lines in a least squares fit to the common vanishing direction.</p> |
