ABSTRACT:
In a method for measuring the velocity of a fluid visualized by the injection of tracer particles, the particle pathline images are imaged by the use of an interlaced scanning type television camera and logical products between pairs of field pictorial image data derived form a frame pictorial image of the output from the television camera is calculated. The correspondence among the particle pathline images of the field pictorial image data is determined on the basis of the logical products. The pairs of field pictorial image data can be obtained from a set of image pickup apparatuses whose exposure time periods are controlled so as to overlap partially.
