Assignee: CHINA UNIVERSITY OF PETROLEUM (EAST CHINA)
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A method for constructing a digital rock, comprising:
obtaining a digital rock training image, wherein the digital rock training image is a digital rock sample image of a known rock;
extracting a plurality of sub-samples from the digital rock training image, and storing all the sub-samples as a sample set;
training a generative adversarial network (GAN) using the sample set and a random sample noise to obtain a digital rock construction model, wherein the digital rock construction model is the GAN trained using the sample set and the random sample noise, and the digital rock construction model is configured to construct a target digital rock image;
obtaining a target random noise; and
inputting the target random noise into the digital rock construction model to obtain the target digital rock image,
 wherein obtaining a digital rock training image comprises:
scanning the known rock using an image scanning technology to obtain a grayscale image of the known rock;
extracting a representative elementary volume (REV) from the center of the grayscale image of the known rock, and smoothing the REV to obtain a smooth digital rock image; and
segmenting the smooth digital rock image using a watershed segmentation method to obtain the digital rock training image.
