摘要
针对摄影测量三维建模向全自动化发展的背景,该文基于SURE摄影测量软件,实现了自动化建立三维场景。阐述了主要的处理环节,包括密集匹配、平差交会、三角构网及贴图等,可生产的产品包括密集点云、真正射影像、数字表面模型、不规则三角网及三维贴图场景;通过分析匹配效率及点云和数字表面模型的精度,显示出其产品均可达到测量级精度。使用高重叠度或倾斜影像,SURE还可以生产出精美的三维城市模型;充分挖掘每一个像素的高精度三维坐标,是其在同类软件中的一大特色。
In view of the trend of automatic 3D modeling, this paper took use of the SURE software and realized the workflow of turning imageries into the 3D scene models. The processing is fully automatic. Main workflow was discussed, including the dense matching, triangulation, meshing and texturing. It can produce the dense point cloud, true ortho photo, digital surface model, TIN and the textured 3D meshes. By analyzing the matching efficiency and points, DSM accuracy, SURE showed its ability to produce the surveying level products. Using high overlapped or oblique imageries, SURE can also make the nice 3D cities. This software explores the precise coordinates of every pixel and become the main highlight over other competitors.
