Abstract:
A measuring system using laser technique for obtaining measurement data of three-dimensional objects in an interior space, comprising:a laser scanner for emitting and receiving laser induced pulses containing the measurement data, wherein said laser scanner creates a semicircular fan of measuring rays;a levelling device connected to said laser scanner for rotating said laser scanner 360 degrees;a recording device for receiving said measurement data; anda measurement data evaluator for digitizing and placing said measurement data in a mathematical correlation to its adjacent point, evaluating an existing cloud of points created by the object in the interior space by allocating points to clusters, mathematically recording said correlations in a surface structure by two-dimensional regression, defining types of planes by analytical expressions of a plane in space according to position and enhancement, wherein said planes are combined in such a way to provide straight lines for constructing a 3D model.
