Abstract

The embodiment of the invention provides a control method and device for pipeline model reconstruction and an upper computer. The method comprises the steps that a first image and a second image are acquired from a multi-view visual map library; Preprocessing the first image and the second image respectively; Performing canny operator contraction processing on the preprocessed first image to obtain a two-dimensional center line point cloud of the first image; Applying a snake model force field to the preprocessed second image to obtain a pipeline edge of the second image; Performing polar lineconstraint processing on the pipeline edge according to the two-dimensional central line point cloud to obtain a central line point cloud of the pipeline edge; Obtaining a three-dimensional center line point cloud of the target pipeline according to the two-dimensional center line point cloud and the center line point cloud of the pipeline edge; And generating a pipeline model of the target pipeline according to the three-dimensional center line point cloud. According to the scheme of the invention, the upper computer reduces the pre-preparation step in the existing pipeline reconstruction through the method, and improves the pipeline reconstruction efficiency while ensuring the precision.

Description

technical field [0001] The invention relates to the technical field of pipeline model reconstruction, in particular to a control method, device and upper computer for pipeline model reconstruction. Background technique [0002] The pipeline is an important part of the spacecraft propulsion system, thermal control system, and environmental control and life protection system. The storage tanks, valves, reasoners and other components of each system are mainly connected by pipelines. In order to ensure the processing and installation accuracy of the pipeline, it is necessary to quickly and accurately measure the pipeline before installation. Pipelines generally consist of straight lines and arcs. During the pipeline measurement process, it is necessary to obtain the information of the straight line section and the arc section of the pipeline accurately and quickly. [0003] Traditional pipeline measurement methods such as profiling and three-coordinate measuring instrument met...
