Problems solved by technology
[0004] Since the inspection well is also a part of the pipeline connection, and it is closer to the ground, it is more likely to be damaged due to extrusion force. Therefore, in the process of pipeline inspection, how to construct the overall model of the pipeline and the inspection well based on the relationship between the pipeline and the inspection well The overall model to detect pipelines has become an urgent issue in the industry

The invention provides a three-dimensional model construction method and device, electronic equipment and a storage medium. The method comprises the steps that a first three-dimensional point cloud model of a target pipeline and a second three-dimensional point cloud model of a target inspection well communicated with the surface of the target pipeline are acquired; obtaining first boundary point cloud data corresponding to a first boundary of the first three-dimensional point cloud model and second boundary point cloud data corresponding to a second boundary of the second three-dimensional point cloud model; determining a first overlap ratio of the first boundary point cloud data and the second boundary point cloud data; based on the first overlap ratio, judging whether the first three-dimensional point cloud model and the second three-dimensional point cloud model are successfully fused or not; and acquiring a three-dimensional overall model of the target pipeline and the target inspection well under the condition that the fusion is determined to be successful. The three-dimensional models of the pipeline and the inspection well are fused to obtain the overall model of the pipeline and the inspection well, overall three-dimensional visualization of the pipeline and the inspection well is achieved, and the accuracy of detection and analysis of the pipeline in the later period can be improved.
Description
technical field [0001] The present invention relates to the technical field of three-dimensional point cloud modeling, in particular to a three-dimensional model construction method, device, electronic equipment and storage medium. Background technique [0002] Pipelines are usually divided into pipelines buried in the ground, and inspection wells that are connected to the pipelines and set at regular intervals to facilitate regular inspections. [0003] In the prior art, when the pipeline is inspected, only the pipeline itself is inspected, and the inspection well is ignored, or part of the inspection well data from the perspective of the pipeline is directly obtained to make a preliminary judgment on the state of the inspection well. [0004] Since the inspection well is also a part of the pipeline connection, and it is closer to the ground, it is more likely to be damaged due to extrusion force. Therefore, in the pipeline inspection process, how to construct the overall m...
