Pipeline defect identification method and device, terminal equipment and storage medium

Abstract

The invention belongs to the technical field of underground pipeline defect detection, and provides a pipeline defect identification method and device, terminal equipment and a storage medium, and the pipeline defect identification method comprises the steps: determining three-dimensional point cloud data of a depth image through obtaining the depth image, a color image and space trajectory information of a pipeline; and determining a first pipeline defect identification result according to the three-dimensional point cloud data and the space trajectory information, determining a second pipeline defect identification result through a preset pipeline defect identification algorithm and the color image, and determining a pipeline defect grade according to the first pipeline defect identification result and the second pipeline defect identification result. That is, the pipeline defect grade is determined by combining the three-dimensional point cloud data of the depth image and the double pipeline defect identification result of the color image, so that automatic detection and identification of the pipeline defects are realized, the defects of poor precision and strong subjectivity of manual detection are overcome, the accuracy of pipeline defect identification is improved, and the identification efficiency is improved at the same time.

Description

technical field [0001] The invention belongs to the technical field of underground pipeline defect detection, and in particular relates to a pipeline defect identification method, device, terminal equipment and storage medium. Background technique [0002] The underground pipe network is an important urban infrastructure and the lifeline to ensure the normal operation of urban functions. During the construction and use of underground pipelines, they will be subjected to various continuous or discontinuous physical, chemical and biological effects, which often produce defects of varying degrees. Among them, pipeline defects can be divided into two categories: structural defects and functional defects. Structural defects refer to the damage of the pipeline structure body, which affects the strength, stiffness and service life of the pipeline; functional defects refer to the defects that lead to changes in the water-passing section of the pipeline and affect the smooth perform...
