METHOD TO MEASURE HIGH PRECISION PARTICLE IMAGE VELOCITY BY CORRELATION COEFFICIENT AND OPTICAL-FLOW INTEGRATION METHOD

摘要

According to a first embodiment of the present invention, a particle tracking method is capable of analyzing the displacement of a particle by photographing a flow field, including at least one tracking particle able to be identified through multiple photographed images, at regular time intervals. The method includes: a step of including at least one tracking particle, and dividing each of the images into pixel areas by unit of an analysis area which is a pixel area of a regular size to track the included tracking particle; a step of calculating a correlation coefficient by unit of the analysis area for each of the images based on the tracking particle included in each analysis area in a mutual position between the images; and a step of calculating the average velocity distribution of the tracking particle, included in each analysis area, between the images based on the calculated correlation coefficient.;COPYRIGHT KIPO 2016
