Abstract
A PC-based machine vision system for obtaining three-dimensional parti cle co-ordinates using a single camera is presented. Based on photogra mmetric imaging, this system uniquely combines the advantages of stere o and orthogonal views to determine the accurate locations of the part icles. A 3D cross-correlation algorithm has been implemented to follow the particles from frame to frame and compute the velocity vectors. E xperiments have been carried out to obtain the velocity profiles in a cubical test section with an offset inlet and outlet. The results obta ined from the experimental investigation were compared with numerical simulation data obtained from FLUENT and STAR-CD. (C) 1997 Elsevier Sc ience Ltd.
