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。
Utilize the rules to unify the semantic formal expression between three-dimensional entities to provide a unified method for modeling. Based on the framework of 3D vector data model, a data format is established according to rules such as straight borehole, oblique hole, section, contour line, fault and wrinkle respectively. The multi-source geological data are standardized and fused by the data Geological surface and geological body quickly build, put forward the establishment of a three-dimensional vector data model based on the rule base. At the same time, the methods of automatic construction of three-dimensional model suitable for all kinds of geological features are studied, including multi-source data coupled layered geological body automatic modeling technology, partition-splicing automatic modeling technology based on cross-section cell division, Modeling techniques, three-dimensional geological attribute modeling techniques under space constraints. Under the premise of ensuring the accuracy of the model, the workload of artificial interaction modeling is minimized and the modeling efficiency is improved.
