[0026] The present invention will be described in further detail below in conjunction with accompanying drawing,

[0027] A method for realizing three-dimensional visualization of soil microstructure surface morphology, the steps of which are:

[0028] A. Cropping SEM image 1:

[0029] Scanning electron microscope photography was carried out to obtain the original SEM photos characterizing the microstructure of the soil (attached figure 2 ), with figure 2 The lower part is the attribute information of the image, such as scale, picture name, etc., which can be removed by using the cropping function in the image processing software Photoshop software produced by Adobe Corporation of the United States. The specific operation is: click "File" in the operating interface of the Photoshop software, click "Open", select the SEM image to be operated, and then click "OK", then the SEM image will be displayed in the Photoshop software, click "Cutting Tool", Click "Rectangle Tool", a...

Abstract

The invention discloses a method for implementing microstructure surface morphology three-dimensional visualization of soil. The method comprises the following steps of: (1) cutting an SEM (scanning electron microscope) image: removing SEM image attribute information by a cutting function of image processing software Photoshop; (2) converting the SEM image into a gray level image: obtaining the gray level image of the SEM image through mathematical software MATLAB; (3) extracting a gray value: obtaining corresponding gray value of each pixel of the SEM image through the MATLAB; (4) obtaining three-dimensional information data of the SEM image: sorting the three-dimensional image information according to certain format, and storing the three-dimensional image information as a txt file; and (5) implementing the three-dimensional visualization, specifically, importing the three-dimensional image information, generating a three-dimensional surface space pattern by graphics software Surfer, and performing visualized operations. The method is easy to perform and simple and convenient to operate, and sets the gray level to be the distance between a microstructure surface to an imaging surface so as to obtain the three-dimensional microstructure information of the soil and implement the establishment and the visualization of a three-dimensional model of the microstructure surface morphology of the soil.

Description

technical field [0001] The invention relates to the technical field of three-dimensional visualization of soil microstructure surface morphology, and more specifically relates to a method for realizing three-dimensional visualization of soil microstructure surface morphology by using scanning electron microscope images. Background technique [0002] A large number of facts show that the engineering properties of soil are largely controlled by its microstructure system, and the various deformation and strength characteristics of soil are in the final analysis a comprehensive reflection of the adjustment and evolution of its internal microstructure elements. Therefore, research Microstructure can understand the essence of many engineering properties of soil, understand the mechanism of artificial improvement of soil properties, especially to establish the correct soil constitutive relationship and explain macroscopic phenomena. [0003] Electron microscope scanning is one of t...
