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

Claim 5:
6. A system for constructing a digital rock, comprising:
a digital rock training image module, configured to obtain a digital rock training image, wherein the digital rock training image is a digital rock sample image of a known rock,
a sample set module, configured to extract a plurality of sub-samples from the digital rock training image, and store all the sub-samples as a sample set;
a digital rock model module, configured to train 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;
an obtaining module, configured to obtain a target random noise; and
a target digital rock construction module, configured to input the target random noise into the digital rock construction model to obtain the target digital rock image;
wherein the digital rock training image module comprises:
a scanning unit, configured to scan the known rock using an image scanning technology to obtain a grayscale image of the known rock;
a smoothing unit, configured to extract a representative elementary volume (REV) from a center of the grayscale image of the known rock, and smooth the REV to obtain a smooth digital rock image; and
a segmentation unit, configured to segment the smooth digital rock image using a watershed segmentation method to obtain the digital rock training image.
