Pipeline inner wall spraying quality detection method based on single-color image feature weighting

Abstract

The invention discloses a pipeline inner wall spraying quality detection method based on single-color image feature weighting. The method comprises the following steps: acquiring a first image and a second image of a to-be-detected ductile iron pipeline inner wall under first single-color light and second single-color light; processing the first image and the second image through a convolutional neural network to obtain a first feature map and a second feature map respectively; enabling the first feature map to pass through a first space attention mechanism module to obtain a first attention feature map; enabling the second feature map to pass through a second space attention mechanism module to obtain a second attention feature map; performing global average normalization processing on the first attention feature map and the second attention feature map to obtain a first local feature map and a second local feature map; fusing the first local feature map and the second local feature map to obtain a classification feature map; and enabling the classification feature map to pass through a classifier to obtain a classification result.

Description

technical field [0001] The present invention relates to the technical field of deep learning and neural network, and more specifically, to a method for detecting the spraying quality of the inner wall of a pipeline based on the weighting of monochrome image features, a system for detecting the quality of spraying on the inner wall of the pipeline based on the weighting of monochrome image features, and Electronic equipment. Background technique [0002] Ductile iron pipe has the advantages of thin wall, good toughness, high strength and corrosion resistance. It adopts flexible interface, which is convenient for construction and safe in operation. Water pipes are widely used in municipal water supply and drainage projects. Since the ductile iron pipe itself has good anti-corrosion properties, it generally only needs to be sprayed with traditional anti-corrosion paint. However, since nodular cast iron pipes are used in municipal water supply and drainage projects, in additio...

AI Technical Summary

Problems solved by technology

However, since nodular cast iron pipes are used in municipal water supply and drainage projects, in addition to the anti-corrosion spraying of the outer wall, the anti-corrosion spraying of the inner wall is also very important, and the existing device for spraying the inner wall of nodular cast iron pipes is likely to have uneven spraying , the problem of different spraying thickness

[0003] At present, due to the lack of methods to detect the spraying quality of the inner wall of ductile iron pipes, the spraying quality can only be guaranteed by additional spraying of anti-corrosion materials, which will cause a great waste of anti-corrosion materials
