实景三维技术在道路规划中的应用

随着实景三维技术不断推进发展，将基于倾斜摄影技术获得的实景三维数据集成在集景三维平台中，可实现道路快速三维建模，再通过叠加空间管控要素、现状限制因素等，实现了规划的三维可视化分析。以仙马湖组团路网优化研究为例，验证了基于实景三维路网优化方法的可行性，使规划路网与地形贴合更好，与现状控制因素协调更优，与河道水系亲水更佳，避免了城市建设大挖大填，取得了良好的生态效益和经济效益，践行了绿色生态发展理念。

Application of Live-action 3D Technology in Road Planning

With the continuous advancement and development of live-action 3D technology, the live-action 3D data obtained by the oblique photography technology is integrated into the collecting-view 3D platform, which can achieve the rapid 3D modeling of roads. By overlaying the spatial control elements, current limiting factors, etc., the planned three-dimensional visualization analysis is achieved. Taking the optimization study of the road network in the Xianmahu cluster as an example, the feasibility of the 3D road network optimization method based on real scenes is verified, which makes the planned road network better fit with the terrain, better coordinate with status quo control factors, and better hydrophilic with river system in order to avoid the large-scale excavation and filling in urban construction. The good ecological and economic benefits are obtained, and the concept of green ecological development is practiced.
