Abstract

The invention relates to the technical field of artificial intelligence, in particular to a mechanical part corrosion crack detection method based on artificial intelligence. The method comprises the following steps of acquiring a crack defect image of a mechanical part to obtain a crack defect area, and refining the cracks in the crack defect area to obtain a refined image; acquiring a crack end point in the refined image according to the continuity of the crack, and repairing the interrupted crack in the refined image based on an expansion region of the crack end point; and obtaining a plurality of crack sections of the repaired crack by utilizing the branch characteristics of the crack, and obtaining the damage degree of the crack defect to the mechanical part according to the length and angle of the crack sections so as to take corresponding measures according to the damage degree. The broken crack is repaired according to the continuity and branch characteristics of the crack, and the repaired crack is analyzed to obtain the damage degree of the crack to the mechanical part, so that the detection result is more accurate and reasonable, and the detection error is reduced.

Description

technical field

[0001] The invention relates to the technical field of artificial intelligence, in particular to an artificial intelligence-based corrosion crack detection method for mechanical parts. Background technique

[0002] Under the combined action of stress and corrosive medium, mechanical equipment parts will appear brittle cracking phenomenon below the material strength limit, which is called stress corrosion cracking. The appearance of cracks will reduce the safety of the structural system, and even lead to the failure of the whole part. Therefore, it is necessary to detect the stress corrosion cracks on the surface of the parts, and obtain the degree of damage to the surface of the parts, so as to determine the subsequent processing operations of the mechanical parts.

[0003] Today's mainstream crack measurement methods mainly include the potentiometric method and the compliance method. The potential method is based on the conductivity of metal components to ...
