地下管线多源数据融合技术方法探索

Exploration of multi source data fusion technical method for underground pipelines

随着城市建设的不断发展,保证地下管线数据的精确性和完整性显得尤为重要。本文通过分析不同取舍要求和不同采集标准的地下管线数据在表示相同实体时存在的差异,研究了将地下管线多源数据融合在一套平面位置、高程、属性信息下的技术方法,实现了管线多源数据在语义表达、空间位置、要素关系等逻辑层次上的融合,为建设统一、实时更新、共建共享的“三维地下城市”管线数据库提供技术支撑。

With the continuous development of city construction,it is particularly important to ensure the accuracy and completeness of underground pipeline data.This paper analyzes the differences in representing the same entity in underground pipeline data with different selection requirements and collection standards,and studies the technical method of integrating multi source pipeline data into a set of unified data in a plane position,elevation,attribute information.It achieves the fusion of multi source pipeline data at logical levels such as semantic expression,spatial location,and element relationships,in order to build a unified,real time update,co construction and sharing of a 3D underground city pipeline database to provide technical support.
