摘　　要：本文提出了一种基于Leica CityMapper混合数据的地形级地理场景构建方法,并对该方法的主要步骤和关键技术进行了阐述。通过省级实景三维建设实例进行验证分析,结果表明,采用该技术进行地形级实景三维更新,具有高程精度高、纹理与模型时相一致、节省更新成本等特点。该技术在地形级地理场景更新,尤其是带状区域(新建高速铁路、公路、运河等)的更新方面具有明显优势,具有极高的推广应用价值。This article proposes a terrain level geographic scene construction method based on Leica CityMapper mixed data,elaborates on the main steps and key technologies involved in this method,and verifies and analyzes it through a provincial-level real-life 3D construction example.The results show that this technology has the advantages of high elevation accuracy,consistency between texture and model time and saes updating cost.This technology has obvious advantages in the updating of terrain level geographical scenes,especially in the updating of banded areas(new high-speed railways,highways,canals and so on),which has high application value.
