Abstract (en)
[origin: EP2251849A2] The method involves projecting a potential line measurement points in a horizontal plane. The points are identified by a polynomial phase transformation and subsequent spectral analysis of line patterns. Other potential line measurement points are projected in a predetermined distance from a detected line in a vertical plane to a horizontal plane.
