摘要
随着现阶段数字线划图的广泛应用,基于对无人机影像DLG产品生产的研究分析,文章阐述了利用无人机影像进行数字线划图(DLG)生产的全过程。从无人机及内业软件的选择、影像采集、航摄像片图像处理、内业矢量化、成果输出及质量检查等方面进行论述。内业处理借助于VirtuoZo软件,生产高质量高精度并应用于多领域的数字线划图。
With the wide application of digital line drawing at present,based on the research and analysis of UAV image DLG product production,this paper describes the whole process of digital line drawing(DLG)production using UAV image.This paper discusses the selection of uav and internal software,image acquisition,aerial camera image processing,internal vectorization,output and quality inspection.In this paper,with the help of VirtuoZo software,the production of high quality and high precision and applied to many fields of digital line drawing.
