Multi-source POI data matching and fusion method

Abstract

The invention discloses a multi-source POI (Point of Interest) data matching and fusing method, which comprises the following steps: acquiring multi-source POI data, and carrying out data preprocessing on the multi-source POI data to obtain multi-source preprocessed POI data; correcting the spatial position of the multi-source preprocessed POI data based on the topological relation between the building two-dimensional surface data and the POI data; determining a plurality of matching schemes according to the multi-source preprocessed POI data after the spatial position is corrected, and matching the multi-source preprocessed POI data after the spatial position is corrected according to the plurality of matching schemes to obtain a matching result; and based on a matching result, fusing the multi-source preprocessed POI data to obtain POI fused data. According to the method, the incomplete POI address is complemented, then the spatial position of the POI is corrected, then matching is carried out according to a plurality of matching schemes, so that matching is comprehensive, the matching calculation amount is small, fusion is carried out after matching, and the number of the fused POI data is more complete. 本发明公开了一种多源POI数据匹配和融合方法，方法包括：获取多源POI数据，并对多源POI数据进行数据预处理，得到多源预处理POI数据；基于建筑二维面数据与POI数据的拓扑关系，纠正多源预处理POI数据的空间位置；根据纠正空间位置后的多源预处理POI数据，确定若干匹配方案，并根据若干匹配方案，将空间位置纠正后的多源预处理POI数据进行匹配，得到匹配结果；基于匹配结果，对多源预处理POI数据进行融合，得到POI融合数据。本发明通过补全不完整的POI地址，然后纠正POI的空间位置，接着根据若干匹配方案进行匹配，使得匹配全面且匹配计算量小，并在匹配之后进行融合，使得融合后的POI数据的数量更加完整。
