利用倾斜摄影三维模型生产1m格网DEM数据的研究
Research on 1 m Grid DEM Data Production Based on Oblique Photogrammetry 3D Model
摘要
Abstract
In this paper,we proposed and validated a rapidly production method for 1 m grid digital elevation model(DEM)data based on oblique photogrammetry 3D model.Adhering to the principle of"multiple applications from one survey",maximizing data value,we explored efficient pathways for producing high-precision DEM derivatives.The research stems from practical implementation in the aided-Xinjiang real scene 3D city construction project.Results demonstrate that through technical optimizations in key stages,including data acquisition,3D modeling,and point cloud filtering,high-precision DEM can be efficiently produced from oblique photogrammetry models,which significantly reduces field-work requirements and human-induced errors while enhancing both data quality and production efficiency.This research provides a novel technical approach for DEM data production,offering important practical implications for advancing the geographical information industry development.关键词
