Refined characterization method of micro CT scanning soil body space pore structure

A refined characterization method of a micro CT scanning soil body space pore structure includes the steps of firstly, conducting three-dimensional dual-value matrix characterization of an image, wherein a micro CT dual-value digital image is composed of m*n pixel points, the value of each pixel point is 0 or 1, the dual-value digital image substantially corresponds to a two-dimensional dual-value (0/1) matrix, each element in the matrix corresponds to the corresponding pixel point in the image, when the value of a certain matrix element is 0, it shows that a pixel corresponding to the element is a pore, and when the value is 1, it shows that the pixel corresponding to the element is a particle; secondly, calculating a volume pore rate and space pore distribution, wherein the volume pore rate of a sample is calculated and the pore rate distribution is presented by analyzing the cross-sectional image sequence; thirdly, extracting any section of the space, wherein the head line and row and the tail line and row
