Digital image segmentation method, device and equipment considering fractal features of rock pores

The invention provides a digital image segmentation method, device and equipment considering rock pore fractal features, and the method comprises the following steps: determining the pore fractal dimension, the maximum pore size and the minimum pore size of a single scanning digital image, and determining the surface porosity of the single scanning digital image; determining a segmentation threshold value of the scanned digital image based on the surface porosity; and based on the segmentation threshold, carrying out segmentation processing on the scanned digital image by adopting a binarization segmentation algorithm. Based on the fractal principle, the digital image segmentation method considering the fractal features of the rock pores is established on the basis of a traditional binarization segmentation algorithm with the actually measured porosity as the constraint, and the method has the advantages of being high in accuracy, low in cost, high in speed and the like. 本发明提供了一种考虑岩石孔隙分形特征的数字图像分割方法、装置和设备，所述数字
