A stereophotography is often used in the field of photogrammetry, but is little used in measurement of a three-dimensional flow field because of the complexity of date processing.
In this study, the three-dimensional flow field around a circular cylinder is visualized by tracer method and the instantaneous positions of several tracers are measured by a stereophotography. The velocity by a stereophotography is also compared with the velocity by another method.
