基于地理知识图谱的道路三维模型语义构建OA

To enhance the effective connection and management of three-dimensional(3D)road model data with existing geographic information data and industry thematic data,improve the utilization efficiency of 3D models,and fully utilize data value,this paper conducted research on the data organization of 3D road models and the semantic information construc-tion method for traffic component-level 3D reality results.Taking the construction of a road knowledge graph as the core framework and combining mileage information conversion under linear referencing and two-dimensional and 3D matching technologies,this paper adopted a rule-based method to achieve the semantic completion of 3D road models,finally forming a complete and standardized data organization form and a semantic information construction method for 3D road models.This method has been effectively applied in the digital construction of ordinary national and provincial highways in Jiangsu Province.The standardization of the data organization of 3D road models and the completeness of relevant semantic results play an important role in improving the management and utilization efficiency of 3D road model data,and the research results of this paper can provide support for the digital upgrading of the industry.
