Abstract

The paper describes an in-line viewing system for use in stereo vision and its practical implementation in 3-component, PIV studies in a wind tunnel. The transformation equations, relating image co-ordinates to object position, are developed and the significance of view matching and quantisation in error propagation are discussed and the resulting errors estimated. Directional ambiguity is resolved by pulse intensity coding and the use of an intensity sensitive image tracking algorithm. © 1995 Springer-Verlag.
