The liquid drop detection technology based on image analysis is of great importance to study liquid properties

and shape parameter of sample is an important parameter for characterizing droplet properties. Droplet detection system based on CCD camera image acquisition is designed

use image processing technologies

such as filtering

denoising

binary processing

and extract width-length ratio

complexity

shape parameter

centrifugal rate

etc.

outline shape of droplet profile is analyzed combined with polynomial fitting and hierarchy analysis method. Experimental results show that the image technology has practical feasibility in liquid drop detection technology.
