<p>The rotating laser (1) has laser beam source for generating laser beam (11). The laser beam is irradiated towards wall surface (32) via reference path, to define laser surfaces (34a,34b) and reference lines (35a,35b). The laser surfaces are tilted relative to rear surface at different inclination angles. The distance between the reference lines is detected when tilting laser surfaces. One of the inclination angles of laser surfaces is determined as vertical tilt angle, when distance between reference lines at respective inclination angle is lowest value. Independent claims are included for the following: (1) method for aligning laser surfaces; and (2) computer program product comprising computer readable storage medium storing instructions for aligning laser surfaces.</p> |
