摘要
针对正射影像纠正时房屋数据采集问题,本文利用ARCGIS、AutoCAD等图形处理软件,结合已有的DLG (Digital Line Graphic)矢量房屋数据,在DSM (Digital Surface Model)的基础上通过少量的人工编辑处理,实现正射影像纠正,从而减少房屋采集工作量,提高DOM (Digital Orthophoto Map)生产效率,通过生产实践多个项目的检验,验证了本文方法的可行性。
Aiming at the problem of building data acquisition in correction of orthophoto images, this paper proposes a new method, by using ARCGIS, AutoCAD and other graphics processing software, combining with the existing DLG (Digital Line Graphic) vector house data, and a small amount of manual editing and processing on a DSM (Digital Surface Model), to correct orthophoto images, thus reducing the workload of data acquisition for houses and increasing the production efficiency for DOM (Digital Orthophoto Map). The feasibility of this method is verified by multiple projects in production practice.
