倾斜摄影测量在地形测绘中的应用

Application of Tilt Photogrammetry in Topographic Surveying and Mapping

倾斜摄影测量技术是近十几年发展起来的一项高新技术,它以低成本、高保真、高效率的优势广泛应用于智慧城市、国土空间规划以及农村房地一体测量等地理信息与测绘领域。论文以江西某项目生产制作1∶500地形图为研究对象,应用倾斜摄影测量技术制作1∶500大比例尺地形图,详细阐述了数据获取、三维建模、内业采集、外业调绘和精度检查等关键作业流程。实验证明,倾斜摄影测量技术能满足1∶500地形图精度要求。

Tilt photogrammetry is a new and high technology developed in recent years.It is widely used in the fields of geographic information and mapping,such as smart city,territorial space planning and rural real estate integrated survey,with its advantages of low cost,high fidelity and high efficiency.This paper takes a project in Jiangxi province as an example,in which a 1:500 topographic map is produced.The key operational processes such as data acquisition,3D modeling,internal collection,external drawing and precision check are described in detail.It proves that the tilt photogrammetry technology can meet the requirements of 1:500 topographic map production.
