摘　　要：倾斜摄影测量建模技术是近年来兴起的一项新型技术,在与传统建模方式相比,凭借倾斜像片和POS数据所构建的模型展现出具有高仿真度、高效率等特点。为解决桂林市新建楼房高度对周边风景名胜可能产生的遮挡时,用模拟仿真技术,对周边环境进行通视模拟,通过调整建筑高度,达到与周边环境相协调。以桂林市某地区为例,为了模拟规划性建筑对山体的遮挡影响,利用无人机倾斜摄影建模与传统的SketchUp软件建模相结合,将两者构建的模型协同导入LocaSpace Viewer平台,通过软件模拟人眼视角对三维场景进行不同角度的通视分析,并输出不同建筑高度对山体的遮挡效果,以及在三维场景中在关键点位置对山体的通视情况,为城市建筑规划控高分析提供参考方案。Oblique photogrammetric modeling technology is an emerging one developed in recent years.Compared to traditional modeling method,based on the models constructed by POS,it exhibits high fidelity and efficiency characteristics.To solve the problem that the newly constructed buildings in Guilin City may obstructed the surrounding scenic landscapes,the simulation technology is employed to conduct visibility analysis of the surrounding environment.Adjusting building heights aims to achieve harmony with the surrounding environment.Taking a specific area in Guilin as an example,to simulate the impact of planned buildings on mountain visibility,a combination of drone-based oblique photogrammetric modeling and traditional SketchUp software modeling is utilized.Both models are collaboratively imported into the LocaSpace Viewer platform where the software simulates human eye perspectives to conduct visibility analysis of the 3D scene from various angles.The results include the obstruction effects of different building heights on the mountains and the visibility of the mountains from key points within the 3D scene.It provides a reference solution for urban building height control analysis in city planning.
