Abstract

The invention discloses underwater nondestructive flaw detection equipment based on combination of vision and magnetic powder and a treatment method, flaw detection operation is carried out on an underwater pipeline by adopting a magnetic powder and vision combination mode, the underwater nondestructive flaw detection equipment comprises an underwater nondestructive flaw detection device and an underwater movable platform, and the underwater nondestructive flaw detection device is fixed on the underwater movable platform; the underwater nondestructive inspection device mainly comprises a flaw detector control module, a camera module, a communication module and an image processing module, and the underwater movable platform mainly comprises a motion control module. According to the invention, the motion control module is adopted to realize positioning and movement of the underwater movable platform; spraying of the magnetic suspension is realized by adopting a flaw detector control module; a camera module is adopted to collect image information before and after the underwater magnetic defect detector adsorbs the pipeline; a communication module is adopted to upload position information and image information; by extracting magnetic powder inspection data and visual image data and fusing high-level semantic information, autonomous inspection and nondestructive inspection of the underwater pipeline are realized.

Description

Technical field [0001] The present invention relates to the field of underwater non-destructive flaw detection, specifically based on underwater non-destructive flawing apparatus and treatment methods of underwater non-disintegration. Background technique [0002] With the continuous development of marine resources, there are more and more at sea mobile devices and fixed devices, and the underwater pipeline also presents explosive growth. When the submarine pipeline is deep, the seabed wave flow repeatedly Fatigue damage occurs at the pipeline connection; the avail or the fall against the ship will also cause the pipeline damage. It will cause the pipeline to break; if the pipeline is laid in the sand, there is a large rheological unstable sea bed, sometimes It will occur due to the collapse of the seafris, slide, erosion, and the corruption is destroyed. Therefore, the seabed pipeline needs regular inspection. [0003] Traditional pipeline underwater lossless flaw detection tech...
