摘要
建筑物高度获取是城市3维模型构建需要解决的一个主要问题,本文提出了利用城市大比例尺3维DLG数据获取建筑物高度的方法。该方法能够实现大范围建筑物高度的批量求算,解决了建筑物顶部不同结构高度获取难的问题。利用该方法获取的建筑物高度精度高,满足了城市建筑物3维精细建模的需要。
Acquiring building height is a major issue in the construction of city 3D model.The paper puts forward a method of acquiring building heights using large scale city 3D DLG data,which is capable of acquiring building heights in batches and solves the problem of acquiring the height of building of different roof structure.Building heights acquired in this way is high in precision and can meet the requirement of precise modeling of buildings.
