Abstract

The invention discloses an intelligent flaw detection method for the inner wall of an industrial pipe fitting based on image analysis. The intelligent flaw detection method specifically comprises the following steps: step 1, image acquisition; step 2, image processing; step 3, standard setting; and step 4, checking abnormity. The invention relates to the technical field of pipe fitting detection. According to the industrial pipe fitting inner wall intelligent flaw detection method based on image analysis, batch detection of industrial pipe fitting images is achieved in an image batch comparison mode, an intelligent damage identification system with a circulating growth type is constructed, nondestructive flaw detection can be achieved, damage types can be detected, and the detection efficiency is improved. Compared with the prior art, the device has the advantages that the labor capacity is effectively reduced, the detection speed is greatly improved, the device can be well applied to large-batch industrial pipe detection, the flaw detection of a large batch of industrial pipes with the same specification is realized by utilizing a batch comparison and sample comparison mode, the detection speed is high, and the flaw detection quality of the inner wall of the industrial pipe is effectively ensured.

Description

technical field [0001] The invention relates to the technical field of pipe fitting detection, in particular to an intelligent flaw detection method for the inner wall of an industrial pipe fitting based on image analysis. Background technique [0002] Among the current non-destructive testing methods for defects on the inner wall of the pipeline, the conventional magnetic particle testing, penetrant testing and acoustic emission testing technologies are extremely inconvenient to operate inside the pipeline. Some new testing methods, such as metal magnetic memory testing, infrared testing, laser The application of holographic inspection and microwave inspection to pipeline inspection is not yet mature. At present, the most widely used methods for inspection of pipeline inner wall defects mainly include radiographic inspection, ultrasonic inspection, eddy current inspection and inspection methods based on optical principles. [0003] For ray inspection, the disadvantage is th...
