Example Embodiment

[0043] The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0044] The present invention designs a systematic and comprehensive method for non-destructive testing of various types of pipelines in the public pipe gallery of a chemical park. The pipes of the public pipe gallery are long and high. It is difficult for online monitoring to provide a panoramic detection result of the pipeline, and thermal imaging of the pipeline is required. Research on the splicing technology of graphs. Infrared images are grayscale images with no colors or shadows, so to the human eye, the resolution is low and there is no stereoscopic effect; due to the thermal balance of the scene, the long wavelength of light, the long transmission distance and atmospheric attenuation, the infrared image ...

Abstract

The invention relates to the technical field of image processing and mode recognition, and discloses an undamaged detection method for a pipeline. The method comprises the following steps of: S1, acquiring video signals in a preset area; S2, performing image enhancement on a plurality of thermograms acquired in the video signal; S3, processing a plurality of thermograms which are subjected to the image enhancement, and performing image stitching; and S4, performing undamaged detection on the pipeline in the preset area by utilizing a stitched image. According to the method, a technology of image processing and a technology of mode recognition are combined to provide the undamaged detection method for the pipeline. According to the method, the position and leakage of the pipeline are detected by using the processed image, so that the pipeline is not damaged in the detection process, and leakage points of the pipeline can be detected accurately to alarm in time on possible potential safety hazards.

Description

technical field [0001] The invention relates to the technical fields of image processing and pattern recognition, in particular to a pipeline non-destructive testing method. Background technique [0002] The modern chemical industry has entered a highly automated production process. Most of the equipment is in the state of process operation and long-term operation, and some even operate in high temperature, high pressure and corrosive environments, which are flammable and explosive. . Therefore, the monitoring of major equipment in the production process is very important. At present, the practice of strictly implementing the regular overhaul system is generally adopted. This method has a certain degree of blindness and low efficiency. Some unnecessary downtime maintenance will cause production to stagnate and bring additional economic losses. Modern society has higher and higher requirements for product quality and safety. Non-destructive testing technology plays an impor...
