面状实体增量融合过程中拓扑冲突检测及一致性维护方法研究

Topological Conflict Detection and Consistency Maintenance Method in Process of Area Entities Incremental Integration

  • 摘要: 针对目前面状实体增量融合过程中存在的拓扑冲突检测及一致性维护方法局限性强、通用性及效率较低、拓扑差异识别不准确等问题,提出了一种新的基于空间关系模型的拓扑一致性检测及维护方法。该方法在面状增量实体的基础上,设计了包括定性的面状实体拓扑关系类型、定量的位置特征及部分拓扑关系的集成空间关系表达模型,以最新版本数据库中面状增量实体的拓扑关系为冲突检测标准,设计并实现了顾及几何一致性的面状实体拓扑冲突自动检测和一致性维护算法。实验结果表明,该算法精度可达到90%左右,可很好地完成增量融合过程中的冲突检测及拓扑一致性维护工作,针对性强,适用性高。

     

    Abstract: In order to solve the problems such as strong limitations, low versatility and efficiency, and inaccurate topological difference identification of topological conflict detection and consistency maintenance method, et al, in the process of area entities incremental integration, a new topological conflict detection and consistency maintenance method based spatial relation model is proposed. The integrated spatial relationship expression model is designed with qualitative area entities topological relation types, and quantitative geometric features on the premise of area incremental entities. Area entities topological conflict detection and consistency maintenance algorithm is designed and integrated with a standard of incremental area entities topological relationships in the latest version of the database. Experimental results show that the experimental accuracy can reach 90%, and the method can do the work of topological conflict detection and consistency maintenance method in the process of area entities incremental integration very well with good pertinence and applicability.
