    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.

  • Patent number: 9020240
    Abstract: Noncontact coordinate measurement. With a 3D image recording unit, a first three-dimensional image of a first area section of the object surface is electronically recorded in a first position and first orientation, the first three-dimensional image being composed of a multiplicity of first pixels, with which in each case a piece of depth information is coordinated. First 3D image coordinates in an image coordinate system are coordinated with the first pixels. The first position and first orientation of the 3D image recording unit in the object coordinate system are determined by a measuring apparatus coupled to the object coordinate system by means of an optical reference stereocamera measuring system. First 3D object coordinates in the object coordinate system are coordinated with the first pixels from the knowledge of the first 3D image coordinates and of the first position and first orientation of the 3D image recording unit.
