Description

technical field [0001] The present disclosure relates to the technical field of long-distance pipelines, in particular to a method and device for establishing a three-dimensional model of long-distance pipelines. Background technique [0002] Long-distance pipelines (long-distance oil and gas pipelines) refer to pipelines used to transport commodity media between production areas, storage warehouses, and user units. Due to the complex environment of long-distance pipeline laying, it will inevitably bear various loads during long-term operation, such as soil load, temperature load, pressure load, etc. Under these loads, the stress state of the pipeline changes. Once the stress on the pipeline exceeds The strength of the pipe, the pipe will face the risk of fracture and failure, resulting in the leakage of the transported medium. [0003] In order to improve the safety of long-distance pipelines, it is necessary to identify the locations of the pipeline sections with high str...

Problems solved by technology

[0004] In the related art, the 3D model of long-distance pipelines is established by manual repetitive modeling one by one. Due to the long distance of buried long-distance pipelines and the complex environment of field laying, the number of units that need to be created in the 3D modeling process is large, and manual modeling is difficult. There are the following defects: (1) The 3D modeling of the pipeline has a large workload and a long modeling cycle; (2) The repetitive work has a large proportion, which is time-consuming and labor-intensive
