Paper Abstract

This paper presents a non-contact method to measure the so-called moving big particles by using conventional optical measurement together with image processing technique. With a slow-motion CCD camera, real-time images of the particles are taken displaying little bright points distributed on a dark background. Next, the particles in the image are separated from background via binary manipulating so that the whole image contains background pixels whose values are zero and particles pixels whose values are one. Furthermore, mathematical morphology is used to amend the anemographic images caused by CCD scan mode. Finally statistics of the size and number of particles are obtained directly through amended binary images.
