Abstract
A method and system for determining the position of a hand-held power tool on a wall including measuring distances within a plane perpendicular to a tooling axis 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 measures distances in a multitude of angles in an angular range of at least 1° around the at least two directions. From the distance sequence measured by the at least one measurement sensor module a calculation and storing unit automatically calculates a function, wherein extrema represent shortest distances to walls, floor and/or ceiling adjacent to the wall. From said function the calculation and storing unit deduces the shortest distances, and output means provide information about the shortest distances so as to allow positioning relative to the shortest distances.
