摘要
为了高效、准确确定路线方案,将无人机航测、BIM技术综合进行应用。利用无人机进行航测的正射影像及数字表面模型,建立了地理信息三维模型并获取道路中桩高程,同时与传统方法获取的地面高程进行了一致性检验。结合BIM技术,在三维空间中进行公路选线,通过具体项目的应用实例表明该方法可提高设计者路线方案比选的效率,增加公路选线的合理性。
UAV aerial survey and BIM technology are applied to develop the routing scheme effectively and accurately.Using the ortho-image and digital surface model of the UAV aerial survey,the 3D model of geological information is established and the pile elevation in the road is acquired,and the consistency check is carried out with the ground elevation obtained by the traditional method.Combined with BIM technology to select the highway route in 3D space,the application practice of the specific project shows that this method can improve the efficiency of the comparison and selection of route schemes and increase the rationality of highway route selection.
