摘要
随着倾斜摄影测量技术发展和无人机设备的日益先进,全国有较多县、市实现了倾斜模型全域覆盖;数字高程模型(DEM)可用于研究和分析地形、水系流域、地物识别等,是重要的基础地理信息数据。阐述了基于原始倾斜模型的DEM数据生产方法,并使用实测RTK点验证数据精度,证明基于原始模型生产DEM数据的可行性。
With the development of tilt photogrammetry technology and the increasingly advanced UAV equipment,many counties and cities in China have achieved full coverage of tilt photography models;Digital Elevation Model(DEM)can be used to study and analyze terrain,drainage basin,feature recognition,etc..It is an important basic geographic information data.This article elaborates on the production method of DEM data based on the original tilted photography model,and verifies the data accuracy using measured RTK points,proving the feasibility of producing DEM data based on the original model.
