Geometrical method for the determination of the position and orientation of a scanning laser Doppler vibrometer

In this paper, a geometrical method is presented to determine the pose (position and orientation) of a Scanning Laser Doppler Vibrometer (SLDV) with respect to a structural coordinate system. Multiple registration points are used simultaneously in a least-squares sense. The structural coordinates and the corresponding scanning angles are known for each of the registration points. In the geometrical method three steps are involved in the determination of the SLDV pose. Its implementation has been tested by simulated data and experimental data. The results have shown that this method and its implementation are correct and effective. Copyright (C) 1996 Elsevier Science Ltd.
