Abstract

The invention relates to a pipeline inner surface detection method and system, a storage medium and an intelligent terminal, and relates to the field of surface defect detection.The method comprises the steps that a detection device moves in the path direction of a pipeline; obtaining telescopic distance information and moving distance information; determining inner diameter information; judging whether the inner diameter information corresponding to all the elastic telescopic rods is consistent or not; if the inner diameter information corresponding to all the elastic telescopic rods is consistent, the position corresponding to the moving distance information is marked on an electronic map as the corresponding inner diameter information, and the inner diameter information is defined as standard inner diameter information; and if the inner diameter information corresponding to some elastic telescopic rods is inconsistent, marking abnormal information, and defining the inner diameter information as abnormal inner diameter information. The problems that when the hole diameter is small, a detection tool is limited to a certain degree, and the operation and adjustment difficulty is increased are solved, and the device has the advantages of being capable of being applied to a small-hole-diameter pipeline, wide in application range and good in application effect.

Description

technical field [0001] The present application relates to the field of surface defect detection, in particular to a pipeline inner surface detection method, system, storage medium and intelligent terminal. Background technique [0002] The pipeline industry is an important field related to the national economy and people's livelihood. Whether it is installed in various types of buildings such as ventilation, dust removal, drainage, heating pipes, or industrial oil, natural gas, electric power, metallurgy, light industry and other long-distance transmission pipelines, high pipeline quality is required. [0003] Regarding the related technologies mentioned above, the inventor believes that in real life, there are often some small-sized pipes. When the detection space is small, that is, the aperture is small, the detection tools are restricted to a certain extent, and the operation and adjustment are increased. Difficulty, there is still room for improvement. Contents of the...
