基于Inpho的大比例尺数字正射影像制作方法研究

Research on Large-scale DOM Generation Method Based on Inpho

Inpho摄影测量工作站基于经典摄影测量原理,集成优秀算法与先进技术,运用模块化方法,实现空三加密计算及DEM、DSM、DOM等数字化产品的生产。软件凭借算法精良、自动化程度高、成果精度高等优势,在大比例尺航空摄影空中三角测量、正射影像制作领域应用广泛。本文以2021年度沈阳市某区域1∶2 000正射影像制作项目为例,阐述基于Inpho工作站多系列模块的空三加密、数字高程模型生产、正射影像制作方法及技术要点总结。

Inpho photogrammetry workstation is based on the classic photogrammetry theory,integrates excellent algorithms and advanced technologies,and uses a modular method to realize aerial triangulation and produce digital products such as DEM,DSM and DOM.The software is widely used in the field of large-scale aerial photography aerial triangulation and DOM generation due to the advantages of sophisticated algorithms,high degree of automation,and high accuracy of results.Taking the 1∶2000 DOM generation project in a certain area of Shenyang in 2021 as an example,this paper expounds the aerial triangulation,DEM production,DOM generation methods and technical points based on Inpho workstation multi-series modules.
