Abstract
An automated technique is described for reconstructing three-dimensional trajectories of tracer particles in curved circular ducts. Individual particles are tracked in real time by a rotating camera under computer control. A digital imaging system enables the computer to locate the particle, adjust the speed of rotation, and store position and calibration data. By viewing the tube from approximately orthogonal directions, three-dimensional information on the position of the particle is obtained. Its precise location is calculated by tracing rays from the camera to the interior of the tube. This technique yields detailed three-dimensional position and velocity data along a trajectory.
