Abstract

Ellipse feature appears in the cross-section of a wire, and it can complement the line feature to improve wire detection. The previously proposed ellipse feature extraction method requires a wire to be placed parallel or perpendicular to the cross-track. It is, however, difficult to guarantee in practice. This work advances ellipse feature extraction so that we will be able to obtain the feature regardless of the orientation of a wire. The method first applies the Hough Transform to the surface projection of an object image from the ground penetrating radar, and then rotates the 3-D data image according to the orientation angle from the Hough Transform to align with the cross-track, before the extraction of ellipse feature. The proposed method is quite effective and provides high quality ellipse feature to aid the detection of wire in any orientation.
