Abstract | This paper discusses an investigation into the use of photogrammetric techniques at the University of Southern Queensland's Ludwieg tunnel facility. The aim was to show that photogrammetric techniques and compact cameras could be used to achieve sub-millimetre precision in hypersonic speed tracking. The paper provides details on the setup of the imaging cameras, video capture, photogrammetric computation and the results of two aerodynamic experiments. A free-flying projectile constructed from a hollow metal cylinder with a round-nose and flat-tail was tracked using two low-cost Casio high-speed cameras. A set of retro-photogrammetric targets of known coordinates was used for camera relative orientation purposes. Corresponding frames were extracted from the video clips using VirtualDub software and a photogrammetric adjustment was applied to these frames to extract a set of 3D |
