Paper Abstract

In this paper a method is proposed on how to extract cylinders from single 2D images. The operator restricts the search area for the image ellipse from the projected cylinder, and a least- square ellipse is obtained and verified by the operator. By knowing the radius and length of the cylinder, an algorithm using projective geometry back projects the image ellipse to a circle in three-space. The center and normal vector to this circle are obtained. If both cylinder tangents are visible, a better estimate of cylinder axis is obtained. From this a synthetic cylinder is computed and projected onto the original image. If the synthetic cylinder is a good fit, it is transferred to a CAD model of the environment, which is updated. The operator receives an updated version of the environment, which either includes a new cylinder or a better pose estimate of one of the previously identified cylinders.
