Abstract

In this paper, a geometrical method is presented to determine the pose (position and orientation) of a scanning laser vibrometer with respect to a structural coordinate system. Multiple registration points are simultaneously used to determine the pose in a least squares sense. The known information from each registration point is the structural coordinate and the corresponding scanning coordinate. Three steps are involved in the determination of the pose. The least squares method is applied to each of the three steps. The implementation of the geometrical method has been tested by simulated data and experimental data. The results have shown that this method and its implementation are correct and effective.
