This paper describes the model deformation system currently being developed for the National Transonic Facility at NASA Langley Research Center. The photogrammetry system uses up to eight network cameras that are time synced with an external hardware trigger. Camera extrinsics are calculated per frame with a bundle adjustment process with coded targets painted to the floor and walls of the test section. We describe our algorithm pipeline including the coded target system for target correspondence between camera views. We also present our future plans for modernizing the system.
