【摘要】：利用规则统一三维实体间的语义形式化表达,为建模提供统一的方法。利用三维矢量数据模型的框架,对直钻孔、斜孔、剖面、等值线、断层、褶皱等数据源,分别按规则制定一种数据格式,对多源地质数据进行标准化和信息融合,经过地质面和地质体的快速构建,提出了建立基于规则库的三维矢量数据模型。同时研究了适合各类地质特点的三维模型自动构建方法,包含多源数据耦合层状地质体自动建模技术、基于剖面单元格划分的分区—拼接自动建模技术、多约束下复杂地质结构快速建模技术、空间约束条件下三维地质属性建模技术等。在确保模型精度的前提下,尽量减少人工交互建模的工作量,提高了建模效率。
[Abstract]:Rules are used to unify the semantic formal representation between 3D entities, which provides a unified method for modeling. Using the framework of 3D vector data model, the data sources such as straight boreholes, oblique holes, sections, isolines, faults, folds and other data sources are respectively formulated according to the rules to standardize and integrate the multi-source geological data. Through the rapid construction of geological surface and geological body, a 3D vector data model based on rule base is proposed. At the same time, the automatic modeling method of 3D model suitable for all kinds of geological characteristics is studied, including the automatic modeling technology of multi-source data coupled layered geological body, and the automatic modeling technology of partition-splicing based on the partition of section cells. Fast modeling technology of complex geological structure under multiple constraints, 3D geological attribute modeling technology under spatial constraint condition, etc. In order to ensure the accuracy of the model, the workload of artificial interactive modeling is reduced as far as possible, and the efficiency of modeling is improved.
