Abstract

A method to measure three dimensional velocity distribution by analyzing VTR images of visualized flow and examples of its application are presented. In this system, (1) flow is visualized by tracer particles, (2) particle images in consecutive frames recorded by two TV cameras stereoscopically are independently traced and (3) composed by stereo pair matching to calculate three dimensional velocity.<BR>No special device to control camera positions and thier axes is necessary in this system because camera parameters are calculated from four landmarks placed in a flow.
