倾斜摄影测量技术在藏区大比例尺基础地理信息数据生产中的应用

Inclined Photogrammetry Technology in Production of Tibet Areas Large Scale Basic Geographic Information Data

针对藏区城镇分布点多、线长、面窄等特点,本项目应用倾斜摄影测量技术对测区的内外业方案进行了详细设计,阐述了利用多视角影像制作3D数字产品、实景三维数字模型的技术路线,并对各种数字产品的精度进行了统计分析。结果表明:该技术在大面积大比例尺3D数字产品、实景三维数字模型的同步生产方面具有较高的可行性及实践参考价值。

Tibet areas cities and towns is complex. In this paper, inclined photogrammetry technology is used to design the internal and external field of the survey area. The paper describes the use of multi-angle images to manufacture 3D digital products and the 3D digital model technical route, and the accuracy of each digital model was analyzed statistically. The results show that this technology has high feasibility and useful reference value in the boundless large-scale 3D digital products and real-time 3D digital models.
