  • System and method for tridimensional cartography of a structural surface
    Patent number: 8462208
    Abstract: System and method for tridimensional cartography of a structural surface. Two wires are extended in front and along the structural surface so as to define a reference surface. A measuring unit comprising a laser arrangement and a camera is moved in front of the structural surface so as to progressively scan the surface. Tow distinct light planes directed toward the structural surface are projected by means of the laser arrangement. Images of the structural surface containing lines resulting from an intersection of the light planes with the structural surface and four reference points resulting from an intersection of the light planes with the wires are captured by means of the camera. The images are processed to determine the 3D coordinates of the lines defining the mapping in a reference system bound to the reference surface considering the position and the orientation of the measuring unit based on the reference points.
