摘　　要：为解决天地图中海量影像瓦片的快速配准和融合问题,文章针对主节点和省市级分节点影像瓦片地图的特点,设计了基于金字塔模型的地图瓦片快速空间精确配准和影像融合算法,并利用.NET语言编程实现了该算法。通过在天地图·四川建设中的实际应用表明,该算法能解决全色(黑白)影像无法应用于天地图省市级分节点建设的难题,对天地图省市级分节点建设有一定的应用价值。但由于融合数据范围较大且不同地区的数据质量存在差异,在融合过程中仍然需要大量的人机交互工作。In order to solve the problem of fast matching and fusion for massive image tiles in Map World,the paper proposed a fast spatial matching and image fusion algorithm of tile map based on pyramid model according to the characteristics of the master node and the provincial and municipal sub-nodes in the image tile map,which was realized by using.NET programming language finally.Through the practical application in the construction of Map World·Sichuan,it was showed that the algorithm would solve the problem that panchromatic images were not easily applied to the construction of provincial and municipal sub-nodes in Map World,which could provide a reference for the practical application study.However,because the ranges of the fused data were very large with different quality of different regions,there would still need a lot of human-computer interactions in the practical work.
