摘 要: 矿产资源利用现状调查成果数据种类多、数据量大,对其进行传统人工更新效率低、成本高,针对矿产图储量数据高效匹配与自动更新等需求,提出基于先验知识与空间拓扑的智能更新方法。通过分析矿产储量图组织与存储特点,归纳矿产图先验知识并将其转换成图形空间拓扑关系约束,对储量块段图形及其注记之间空间拓扑关系进行分析。将先验知识与拓扑规则应用于矿产图数据变化检测、数据识别与提取、数据匹配、数据更新等关键过程,采用数据字典、叠加分析等方法,实现储量数据的匹配与自动更新。设计、开发自动更新原型系统,实现矿产图文件、储量块段图形、注记圆及相关储量数据属性信息的智能匹配与更新。研究结果表明:采用本文方法通过对储量数据进行更新实验,其更新效率是人工更新的上百倍并能克服人为操作失误,验证了基于先验知识与拓扑规则的矿产图储量数据智能匹配与更新技术的可靠性与有效性。

Abstract:There are many kinds of data and a large amount of data in utilization investigation results of mineral resources, and the traditional manual updating on these data is inefficient with high cost. In order to match and update reserve data of mineral map efficiently and automatically, an intelligent update method based on prior knowledge and spatial topology was proposed. By analyzing the organization and storage characteristics of mineral reserve map, the prior knowledge of mineral map was summarized and transformed into the topological relation. The research was focused on the analysis of spatial topological relationship between reserve block graph and its annotation, and applied prior knowledge and topological rules to the key processes of change detection, data recognition and extraction, data matching, data update, etc. In addition, data dictionary and overlay analysis were used to achieve matching and automatic updating of reserve data. The automatic updating system of mineral reserve data was designed and developed, with which the intelligent matching and updating function of mineral map file, reserve block graph, annotation circle and related reserve data attribute information was realized. The results show that the proposed method updates reserve data with hundreds times efficiemcy than manual updating and without any error caused by manual updating, which verifies the reliability and validity of the intelligent matching and updating technology of reserves data of mineral map based on prior knowledge and topological rules.

 

Key words: reserve blocks; note circles; prior knowledge; spatial topological relationship; intelligent updating
