| 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: | In this paper,we use the rule to unify the semantic representation of 3D entities to provide a unified approach of modeling. Using the framework of 3D vector data model,respectively,according to rules to develop a data format,such as straight hole,oblique hole,profile,contour,fault,fold and other data sources,standardization and information fusion of multi-source geological data,through the rapid construction of geological surface and geological body, a 3D vector data model based on rule base is established.And the automatic construction method of three-dimensional model suitable for all kinds of geological features is studied,including multi-source data coupling automatic modeling technique for layered.Automatic modeling of partitioning-splicing based on section cell partitioning, rapid modeling technology of complex geological structures under multi-constraints and 3D geo-attribute modeling technology with spatial constraints and so on.In ensuring the accuracy of the model under the premise,minimize the amount of human interaction modeling effort for improving modeling efficiency. |
