Paper Abstract

We present a method to detect cylinders in a range image taken from an airplane by a laser ranger scanning the ground at a low grazing angle. First we attempt to detect the outer edges of the cylinder which appear as parallel lines of discontinuity in the range image. The radius of the cylinder is computed from the distance between the two lines of discontinuity. The cylinder rulings appear parallel to the lines of discontinuity in the projection. We find three cylinder rulings and then use two different methods based on geometrical considerations to find the axis of the cylinder given these cylinder rulings. The distance between the axes found by the two methods is used as a criterion for distinguishing between a cylinder and any other geometrical shape.
