<p>The method involves fixing a scanning mirror in a scanning angular position and deriving a displacement value from a reflection signal. A laser scanner (1) is inclined at a scanner longitudinal axis (x') at a predetermined tilting angle, and another displacement value is derived from another reflection signal. A lateral inclination angle is determined from the values and the tilting angle by a trigonometric calculation for reversely tilting the scanner at the tilting angle and tilting the inclination angle, where a scanning plane is aligned parallel to a road plane.</p> |
