This paper describes the setup and analysis method for measuring individual fragment velocities in 3D from HVI experiments. The setup makes use of two synchronized high-speed cameras whose images are further split in half yielding four completely separate views. Having these views allows the vast majority of the identified fragment positions to be determined in 3D without ambiguity. The steps taken to identify, link, correspond, and triangulate each fragment are described in detail. The final result is an approach that is able to measure fragment positions in 3D with sub-millimeter accuracy and 3D velocities with an accuracy of ± 63 m/s. The approach can be applied to study a variety of HVI scenarios ranging from satellite breakup, to momentum transfer, to crater formation.
