倾斜摄影测量技术在三维建模中的应用

Application of Oblique Photogrammetry in 3D Modeling

三维建模已经成为测绘数字化过程中不可缺少的重要一环。Smart3D软件在快速低成本实现精细三维模型的构建、大比例尺DOM的制作以及三维模型的可视化展示等方面拥有巨大优势。本文借助倾斜摄影测量技术和Smart3D软件实现精细三维模型的快速构建,规范和分析了数据获取的主要流程和数据处理的关键技术,对比和探讨了利用点云和影像数据建模的精度和优缺点,总结了三维建模过程中相关数据的质量要求和评价标准。最后指出了影像建模仍面临的一些问题,仍需要进一步研究。

The 3D modeling has become an indispensable part in the process of digital surveying and mapping. The Smart3D software has a great advantage in the construction of fine 3D model,the production of large scale DOM and the visualization of 3D model. Therefore,with the rapid construction of tilt photogrammetry technology and Smart3D software to realize the fine 3D model,specification and analysis of data acquisition and data processing of the main process of key technology,compared and discussed using point cloud and image modeling accuracy and the advantages and disadvantages,summarizes the quality requirements of the relevant data in 3D modeling process and evaluation standard. Finally,it points out some problems still need to be further studied.
