基于空-地多源数据融合的建筑物精细建模研究

针对建筑物精细建模的精度问题,对同一试验区建筑物群的机载LiDAR顶面数据、航空正射影像数据和车载LiDAR立面数据进行试验研究,通过精确提取各建筑物群的顶面和底面矢量轮廓线,对矢量轮廓线间的水平间距进行定性与定量分析,研究结果对空-地多源数据融合进行建筑物精细建模提供可靠的技术支持。

Research on precise modeling of buildings based on multi-source data fusion of air to ground

For the accuracy of precise modeling of buildings ,a test is made on multi‐source data for the building clusters in the same test area ,including top surface data of air‐borne LiDAR ,aerial orthophotos , and facade data of vehicle‐borne LiDAR .After the top and bottom vector contour lines of building clusters are accurately extracted ,a series of qualitative and quantitative analysis are carried out for the level interval between vector contour lines .Research results provide a reliable accuracy support for precise modeling of buildings of air ground multi‐source data fusion .And on the same time ,some solutions to key technical problems are discussed .
