摘要
结合数字地图提供的位置信息,根据选取的建筑物特征点不同的类型,分别应用点点匹配和点线匹配两种测量计算算法,实现单近景影像的建筑物三维测量,试验结果证明,数字地图的单近景影像匹配的建筑物三维测量技术能精确测量出建筑物高度,其精度能够满足三维地理信息数据采集精度的要求。
Combining with location information supplied by digital map,according to different selected architectural characteristics,the paper respectively applies two kinds of measurement and computation methods of point-point matching and point-line matching,and realizes architectural three-dimensional measurement of single close-range image. The experimental results show that: architectural three-dimensional measurement technology matching single close-range image of digital map can accurately measure building height. Furthermore,the accuracy can meet threedimensional geographic information data collecting accuracy demands.
