<p>The invention relates to a method and system for determining the position (23) of a hand-held power tool (1) on a wall (22). The method comprises measuring distances (11) within a plane (9) perpendicular to a tooling axis (8) in at least two directions, comprising at least the direction to one side wall and the direction to the floor or the ceiling. At least one non-contact measurement sensor module (3) measures distances (11) in a multitude of angles in an angular range of at least 1° around the at least two directions. From the distance sequence (11) measured by the at least one measurement sensor module (3) a calculation and storing unit (4) automatically calculates a function (11'), wherein extrema, particularly minima (11a'-11d'), represent shortest distances (11a-11d) to walls, floor and/or ceiling adjacent to the wall (22). From said function (11') the calculation and storing unit (4) deduces the shortest distances (11a-11d), and output means, in particular a display unit (18) and/or acoustical output means, provide information about the shortest distances (11a-11d) so as to allow positioning relative to the shortest distances (11a-11d).</p> |
