Abstract

The invention discloses an evaluation method, device and equipment for a metal corrosion state, and the method comprises the steps: collecting a corrosion image of to-be-assessed power equipment metal, carrying out the color space conversion from an RGB model to an HIS model of the corrosion image, and extracting the colorimetry characteristic quantity of the corrosion image; after carrying out gray scale conversion and preprocessing operation on the corrosion image, calculating the morphology and texture characteristic quantity of the corrosion image; inputting the chromaticity characteristicquantity and the morphology texture characteristic quantity into a target corrosion evaluation network, and outputting a corrosion state evaluation value of the corrosion image; and determining the corrosion degree of the power equipment metal to be evaluated according to the corrosion state evaluation value. According to the method, the device and the equipment provided by the invention, the metal corrosion state evaluation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of corrosion detection, in particular to a metal corrosion state evaluation method, device and equipment. Background technique [0002] Metal materials are widely used due to their excellent physical, chemical and mechanical properties, but they will gradually corrode due to exposure to complex and diverse environments. Corrosion damage will not only lead to the thinning of the metal layer, but also change the mechanical properties of the metal structure, thereby destroying the equipment and causing safety accidents. According to statistics, the annual loss caused by corrosion in my country accounts for about 5% of the gross national product. my country's power grid covers a wide area, and there are huge differences in climate and environment in different regions. There are not only coastal areas with high temperature and high humidity, extremely corrosive acidic soil, saline soil and other harsh corrosive...
