This paper describes new algorithms for detecting
and interpreting linear features of a real scene as im-
aged by a single camera on a mobile robot. The low-
level processing stages are specifically designed to in-
crease the usefulness and the quality of the extracted
features for a semantic interpretation. The detection
and interpretation processes provide a 3-D orientation
hypothesis for each 2-Dsegment. This in turn is used
to estimate the robot's orientation and relative posi-
