摘要
针对传统勘探剖面构模人工干预较多、模型精确性有待提高等问题,研究了一种智能化与人机交互相结合的三维地质模型快速构建方法,并结合该方法对控制模型不确定性的主要因素及约束方法进行了分析。该方法以面向勘探剖面的三维地质模型构建工作流程为主线,通过优化提升各环节自动化、智能化工作程度以提高三维地质模型构建的速度与精度。基于该方法研发的软件功能模块能较好地实现勘探剖面二维平面快速编图及剖面边界三维空间动态重构,进而基于三维勘探剖面实现面向用户自定义属性约束的地质界线动态提取和三维地质模型快速构建。经实际应用检验表明,该方法不仅能有效提高三维地质模型构建的效率和精度,而且对模型几何形态的不确定性程度具有较好的约束控制作用。
Because of numerous human interventions and low precise models in traditional 3 D geological modeling based on exploration sections, a new method which combines intelligence and human-computer interaction in 3 D geological modeling is elicited to improve the efficiency and accuracy of models. On this basis, the main factors and constraint methods of uncertainty in controlling models geometric shapes are analyzed. By enhancing the automation and intelligence of traditional 3 D geological modeling based on exploration sections, the speed and quality of 3 D geological modeling are improved. Some related functions of digital mine software,such as Quanty View realized by this method can realize rapid mapping in 2 D space and automatic reconstruction in 3 D space for exploration sections. Based on those sections, 3 D geological boundaries can be automatically obtained and 3 D geological models can be constructed. The practical application in some mines shows that this method can not only improve the efficiency and accuracy of 3 D geological modeling, but also constrain the uncertainty of 3 D models geometric shapes.
