Abstract

The invention discloses an image artifact elimination method and device and equipment, and relates to the technical field of geotechnical engineering. The method comprises: obtaining an input image, wherein the input image comprises a CT scanning image of a geotechnical material to be measured; identifying a central point of the input image; according to the center point, obtaining position information of each pixel point in the input image based on the center point; obtaining a characteristic curve value according to the position information and the characteristic information of the pixel points; and according to the pixel values and the characteristic curve values of all the pixel points in the input image, obtaining an output image after artifacts are eliminated. The problem that the analysis precision of the microstructure of a scanned object is affected due to ray beam hardening artifacts existing in CT images obtained through medical CT scanning of geotechnical engineering materials in the prior art is solved, and the purpose of improving the quality of CT scanning images is achieved.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to an image artifact elimination method, device and equipment. Background technique [0002] Computerized tomography recognition technology, referred to as CT technology (Computerized Tomography), is used to detect subtle changes in materials and structures. CT scanning is to isolate and image the two-dimensional scanning layer to be detected in the scanned three-dimensional object to obtain a CT image. CT image artifacts are abnormal images that appear during the formation of CT images and have nothing to do with the scanned object. These abnormal images degrade the quality of CT images and affect the study of the microstructure of the scanned object. [0003] When performing microstructural analysis of geotechnical engineering materials such as rocks and concrete, CT scans are performed first. At present, when geotechnical materials are scanned by medical CT, ar...
