摘要
倾斜摄影测量技术的应用正在蓬勃兴起,Smart3DCapture作为全自动三维建模软件,在大范围地形建模方面性能表现卓越。然而,大范围地形建模生产了大量的高分辨率模型文件,给计算机加载与渲染带来了困难。针对这一问题本文提出了一种地形模型重建的方法,简化模型结构,降低分辨率,利用LOD思想组织文件结构,减少场景渲染时的模型数量,提高渲染效率,解决了大范围地形场景的加载与显示问题。
The application of oblique photography technology is booming, Smart3DCapture as a full-automatic 3D modeling software, in the large-scale terrain modeling performance excellence. However, large-scale terrain modeling produces a large number of high-resolution model files, which brings difficulties to computer loading and rendering. Aiming at this problem, this paper proposes a method of terrain model reconstruction, simplifies the model structure, reduces the resolution, uses LOD thought to organize the file structure, reduces the number of models when rendering the scene, improves the rendering efficiency, and solves the loading of large-scale terrain scene and the display problem.
