A fine partition evaluation method for hydraulic structure components based on intelligent identification of sea-land-air three domains

Abstract

The application provides a water conservancy building component fine partition evaluation method based on sea-land-air three-domain intelligent identification, relates to the technical field of intelligent construction and operation and maintenance, and comprises the following steps: collecting global point cloud data and structural defect data of a water conservancy building; segmenting independent components in the global point cloud data based on geometric characteristics, generating component point cloud subsets; constructing a target BIM model, integrating the target BIM model in a GIS platform, and obtaining positioning information of the components in a macro geographical space; comprehensively evaluating the attribute information of each component based on evaluation dimensions, and determining the management and control level of each component; based on the management and control level and the positioning information of each component, corresponding management and control partitions are divided, the unique identification of the components is associated with the management and control partitions; a visual partition map is generated based on the management and control partitions, and a component information list is generated based on the target BIM model and the management and control level, serving as evaluation results. The accuracy, comprehensiveness and management efficiency of the evaluation are significantly improved.
