Abstract

The invention discloses a concrete pore feature extraction method and system. The extraction method includes scanning permeable concrete by using an X-ray tomography, and obtaining a permeable concrete sectional image; performing binary processing on the permeable concrete sectional image, and determining a pore distribution binary image; performing three-dimensional reconstruction processing on the pore distribution binary image, and establishing a pore three-dimensional reconstruction model; and extracting concrete pore features according to the pore three-dimensional reconstruction model and the pore distribution binary image. The extraction method and system can perform nondestructive testing on concrete, so that the accuracy of extracting pore features can be enhanced.

Description

technical field [0001] The invention relates to the field of concrete pore feature extraction, in particular to a concrete pore feature extraction method and system. Background technique [0002] In order to strengthen the understanding of the internal structure of pervious concrete, the existing technology cuts the pervious concrete specimen into several layers, uses a camera to take pictures to obtain cross-sectional images, and performs binary processing on the images to distinguish pores and solid phase materials, and then fits the pores as The equivalent radius and pore area of ​​the circle are extracted; although this method can macroscopically see the internal structure of the pervious concrete, it is necessary to cut out several sections of the pervious concrete specimen, which is not only time-consuming and laborious, but also causes damage to the pore structure. Extract cross-sectional images, the number of images is generally only 3-5, and the randomness is large,...
