摘要: 计算机技术的飞速发展,给道路设计带来了极大的方便,数字摄影测量在道路选线中的应用,其过程主要是利 用全数字摄影测量系统(VirtuoZo)生成DEM(数字高程模型),由建立的带状DEM内插出带状横断面,自动绘制公 路路线平面地形图;再根据平面曲线各个测点的平面坐标和带状DEM内插线状纵断面,最后将线状纵断面进行平 滑处理.

Abstract: With the rapid development of computer technology,enormous convenience is brought for the roads design.The application of the digital photographic survey to the path route selection is indroduced.Th e process is mainly elaborated.Firstly use entire digital photographic survey system(VinuoZo)to produce DEM (digital elevation mode1),through the belt- 8haped DEM interpolation,go beyond a line belt-shaped cross section,and automatically draw the level topographic diagram. Then according to the place coordinates of the level tune segment measuring point and the belt-shaped DEM,interpolate stria tion longitudinal section.Finally can'y on the striation longitudinal section smoth processing.

Key words: digital photogram metric survey, path route selection, application, VirtuoZo
