<p>The method involves determining an effective removal of an illuminated marking point (L1) on an underground from a head of a laser marking unit (4) by a distance measuring device. The point removal is compared with length of a determination vector (V1). A corrected determination vector is computed for a corrected pixel, which is shifted vertically upward or downward to a selected point (P1) based on a deviation of the removal. An actuator is controlled for the head. The determination, comparison, computation and control steps are repeated until the deviation falls below a preset limit value.</p> |
