Claim 3:
4. The method for evaluating the fractal dimension of the particle matter in the dispersing system according to claim 2, wherein the particle radius distribution determination is implemented on the basis of computer image recognition, comprising:
step S110, acquiring a microscopic image by means of a microscopic image capture card;
step S120, removing background or environmental noise by means of median filtering;
step S130, reprocessing the image by means of 0-1 integer optimization;
step S140, marking a connected domain of a particle and the position of a central point thereof according to a seed fill algorithm in the graph theory; and
step S150, calculating the particle radius of the marked particle on the basis of the equivalence principle, and storing the same in a data structure, wherein the equivalence principle refers to using the area of the marked connected domain as the area of a circle, and calculating the radius as an equivalent radius of the corresponding particle, and the particle radius ri of the particle matter and the particle content pi of the particle matter having the particle radius ri are acquired according to stored data of the data structure.
