영문 초록

The present study is aimed to develop a new experimental method to measure velocity components in flow field by image processing technique called Particle Image Velocimetry(PIV). Here is represented a novel particle identifying algorithm by correlating two consecutive frames. And it is compared with four-frame identifying method. resulting in higher processing speed and more effective acquisition of the same particle pairs. The image processing system consists of one commercial image board slit into a personal computer and 2-dimensional sheet light generator and flow picture recording apparatus. Particle labelling, calculation of gravity centers. boundary detection and related techniques are also scrutinized and distribution of interpolated velocity vectors. equi-baric contours are also illustrated as examples.
