A Particle Morphology Characterization System and its Method Based on Particle Scattering Image Recognition

•The transit method in astronomy was firstly referred to detect the shape of microscope particles.•Comparing with the previous work, the accuracy of optical fluid field couple (OFFC) model improved 16.08%.•Comparing with the previous work, the mix sample could be detected and the maximum error of different particles’ proportions was less than 6%.•The scattering patterns and flow trajectory could be analyzed automatically by the algorithm and system proposed in this work.
