Abstract: The disclosure relates to a method for determining a profile section of an object and/or space by means of a 2D laser scanner having a laser rangefinder, including: recording mutually assignable distance measurement values and distance measurement directions by means of the laser rangefinder in a measuring plane traversed radially by a laser beam of the laser rangefinder, determining the profile section, from the distance measurement values and distance measurement directions, determining an angle of inclination of the measuring plane with respect to a reference plane, and correcting the profile section using the angle of inclination of the measuring plane. According to the disclosure, the angle of inclination of the measuring plane is determined by using the laser rangefinder. The disclosure also relates to a 2D laser scanner and to a system.
