Research on Rapid Construction Method for 3D Real Scene Model of Highway Based on BIM

对基于BIM实景建模方法在公路养护领域中的应用进行研究,介绍了通过基于BIM的三维实景建模技术对公路重点养护路段模型进行快速三维实景搭建的方法。三维实景建模选用的软件是Context Capture软件,整个建模过程包括对实际路段以及周边场景实景建模实验,建模过程中对涉及到的数据格式进行转换。整个实验通过对目标实体的快速三维模型搭建,论证了BIM快速实景建模方法的可行性,最后将基于BIM的三维实景建模技术与三维扫描技术进行对比,得出基于BIM技术的两种实景建模方法各有优缺点,二者优势互补,在今后的公路三维实景建模领域中将有更广阔的应用前景。

The application of real scene modeling method based on BIM in the field of highway maintenance is studied in this chapter,and the method of rapid 3D real scene construction for the key maintenance section model of highway based on 3D real scene modeling technology of BIM is introduced.The software used for 3D real scene modeling is ContextCapture.The whole modeling process includes the real scene modeling experiment for the actual road section and surrounding scenes,and the conversion of the data format involved in the modeling process.The feasibility of BIM rapid real scene modeling method is demonstrated through the whole experiment on the rapid 3D real scene modeling construction of the target entity.Finally,the 3D real scene modeling technology based on BIM is compared with 3D scanning technology,so as to obtain the advantages and disadvantages of the two real scene modeling methods based on BIM Technology.The advantages of the two methods complement each other,which will have a broader application prospect in the field of 3D real scene modeling in the future.
