A method to measure micro particulates based on image processing is presented. The particulate image is collected and pre-processed by CCD combined with a image-processing software system
then segmented by threshold mothod. By using flour as specimens and utilizing the dynamic clustering method coded by C++
the 16 particulates with the maximum radius of 1.600 μm
minimum radius of 1.000 μm
average radius of 1.187 5 μm and standard deviation of radius of 0.661 4 have been obtained. The experiment results indicate that the presented method is effective and feasible.
