土地整治中设计模型与三维场景的一种融合方案

An Integration Scheme Between Design Model and 3D Scene in Land Consolidation

在现阶段的土地整治中,设计规划的成果通常都是二维的,不利于展示和解读。提出了一种将规划设计成果进行三维可视化的解决方案。首先利用倾斜摄影技术建立地表的三维场景,然后将设计模型与三维场景进行融合,利用开源的渲染引擎（open scene graph,OSG）对融合的结果进行三维实景展示。鉴于土地整治中模型的复杂性,将土地整治中涉及到的模型分成两大类,针对这两大类分别提出不同的策略来实现模型与场景的融合,最后通过实验来验证本文提出的解决方案的有效性。

In this paper,a solution is put forward for 3D visualization of the planning and designing results.Firstly,we use the oblique photography technology to set up the surface of the 3D scene,then integrate the design model and 3D scene,and display the result with the open source rendering engine open scene graph.In view of the complexity of the model in land consolidation,the models are divided into two categories.Thus,two different strategies are proposed to achieve the integration of the model and the scene according to these two categories.Experimental result shows the effectiveness of the proposed solution.
