摘　　要：CityGML数据因建模方法、模型优化及数据转换等原因所导致的模型几何、拓扑、语义不一致性广泛存在,影响了对其的进一步应用。本文提出并构建了顾及语义约束的CityGML建筑物模型拓扑一致性规则集,设计了对CityGML LOD2/LOD3/LOD4多细节层次建筑物模型数据进行自动检测与修复的算法,并采用OGC官网公开数据对算法进行了验证试验。试验结果表明,所构建一致性规则集具有较好的完备性,算法能够检测出CityGML建筑物模型数据存在的绝大多数拓扑不一致问题,并能对其中部分的拓扑错误和几何错误进行自动修复。The inconsistency of model geometry,topology and semantics of CityGML data caused by the modeling method,model optimization and data conversion are widespread,which affects its further application.A rule set for CityGML building models was proposed and constructed in this paper which takes semantic constraints into account.Relevant algorithms for automatic detection and restoring of CityGML LOD2/LOD3/LOD4 multi-level-of-detail building model data are designed.Open data downloaded from OGC website was used to verify the rules and algorithms.Experimental results demonstrate that the constructed consistency rule set was complete and self-consistent,and proposed corresponding algorithms can detect most of the topology inconsistencies in CityGML building model data,and can automatically repair some of the topological and geometric errors.
