The paper is devoted to the method for 3D reconstruction of the straight
tracks in the tracking system consisting of the drift-chamber stereo layers.
The method is based on the Hough-transform approach - the discrete case of more
general Radon transform - and takes into account both coordinates of the hit
wires and drift distances not only for the measurements in one projection, but
also in the rotated stereo layers.
The proposed method allows one to resolve the right-left ambiguity and
provides the accordance between vertical and horizontal projections of the
track.Comment: 6 pages, 4 figures, submitted to the VIth International
