In the 3D-PTV, 3D coordinates of tracers are determined by the stereo range finding method. Recently authors developed a new efficient method of determining 3D locations of tracer particles from two to three 2D pictures. The method based on the optimum arrangement of cameras and an algorithm which is capable of reducing an amount of calculations in the process of the stereo range finder. The present method has shown such a high performance that can finish all the process in a very short time, for example 25ms to determine a location of one particle utilizing an ordinary 16bit-personal-computer.
