Description

Technical Field

[0001] The present invention relates to the field of gas pipelines, and in particular to a gas pipeline line contact scene recognition system. Background Art

[0002] Gas pipelines are pipelines that transport natural gas (including associated gas produced by oil fields) from mining sites or processing plants to urban gas distribution centers or industrial enterprise users, also known as gas transmission pipelines. Using gas pipelines to transport natural gas is a way to transport a large amount of natural gas on land. Gas pipelines account for about half of the total length of pipelines in the world. Gas pipelines are pipelines that transport natural gas (including associated gas produced by oil fields) from mining sites or processing plants to urban gas distribution centers or industrial enterprise users, also known as gas transmission pipelines.

[0003] In the prior art, during the laying of the gas pipeline, if the gas pipeline comes into contact with the cable, it is easy to cause safety hazards for the subsequent safe use of gas. However, the prior art lacks a high-precision detection mechanism and early warning mechanism for whether the gas pipeline comes into contact with the cable, resulting in the possibility of safety accidents in the use of the gas pipeline. Summary of the invention

[0004] In order to solve technical problems in related fields, the present invention provides a gas pipeline line contact scene recognition system, which can analyze the overall depth of field of the gas pipeline in the artifact-removed image and the overall depth of field of the cable in the artifact-removed image when there is a missing part in the regional geometry of the imaging area occupied by the gas pipeline relative to the standard contour curve corresponding to the gas pipeline, so as to issue a first analysis command to determine the contact between the gas pipeline and the cable when the overall depth of field of the gas pipeline in the artifact-removed image and the overall depth of field of the cable in the artifact-removed image are consistent, and reference a photoelectric warning device to execute a photoelectric warning operation corresponding to the contact between the gas pipeline and the cable when receiving the first analysis command, thereby realizing real-time detection and on-site warning of the dangerous distribution status of on-site cables that dynamically change their positions.

[0005] According to the present invention, a gas pipeline line contact scene recognition system is provided, the system comprising:

[0009] an artifact removal device connected to the data sharpening device, and configured to perform an artifact removal process on the received data sharpened image to obtain and output a corresponding artifact removed image;

[0010] a connection analysis device, connected to the artifact removal device and comprising an area detection device, a shape analysis device and a parameter application device, wherein the shape analysis device is respectively connected to the area detection device and the parameter application device, and the connection analysis device is used to detect an imaging area occupied by the gas pipeline in the received artifact removal image as a target imaging area based on the color imaging characteristics of the gas pipeline, obtain the regional geometry of the target imaging area, and analyze the overall depth of field of the gas pipeline in the artifact removal image and the overall depth of field of the cable in the artifact removal image when there is a missing part in the regional geometry of the target imaging area relative to the standard contour curve corresponding to the gas pipeline, so as to issue a first analysis command to determine that the gas pipeline is in contact with the cable when the overall depth of field of the gas pipeline in the artifact removal image and the overall depth of field of the cable in the artifact removal image are consistent, otherwise, issue a second analysis command to determine that the gas pipeline is not in contact with the cable;

[0011] The photoelectric warning device is connected to the connected analysis device and is used to execute the photoelectric warning operation corresponding to the gas pipeline contacting the cable when the first analysis command is received, and is also used to stop executing the photoelectric warning operation corresponding to the gas pipeline contacting the cable when the second analysis command is received.

[0013] Inventive concept A: A connection analysis device including an area detection device, a shape analysis device, and a parameter application device is used to complete a pixel-level visualization analysis of the contact state between the gas pipeline and the cable, thereby improving the accuracy and efficiency of the contact state analysis between the gas pipeline and the cable;

[0014] Inventive concept B: Specifically, when there is a missing portion in the regional geometry of the imaging area occupied by the gas pipeline relative to the standard contour curve corresponding to the gas pipeline, the overall depth of field of the gas pipeline in the artifact-removed image and the overall depth of field of the cable in the artifact-removed image are analyzed, so as to issue a first analysis command to determine whether the gas pipeline is in contact with the cable when the overall depth of field of the gas pipeline in the artifact-removed image and the overall depth of field of the cable in the artifact-removed image are consistent;
