摘要
在简述地质三维建模图文数据类型和格式的基础上,对构建模型的基础异构数据的集成融合、精度匹配问题进行了分析探讨,并对由此而引起的模型误差产生、传递与积累进行了评述,最终从建模初始的数据输入、系统运行控制角度给出了一些减少误差产生、提高模型精度的措施和方法。
Three-dimensional geological model is the focus in contemporary geology research.In model construction process,the data structure of foundational data exists in numerous data structures.With graphic and text data types and formats of three-dimensional geological model briefly discussed,the integration,amalgamation and precision match of different structural foundational data are analyzed.The generation,transmission and accumulation of model error are evaluated from the viewpoint of initial model data input and model system operation control.Some measures,methods of error reduction and model accuracy promotion are put forward.
