道路三维模型的VR全景建模方法
|
摘要
现代道路设计中会运用BIM技术在Infraworks上建立三维模型,并利用VR全景技术进行模型展示。传统VR全景技术只对实际场景有效,而无法在三维模型上进行作业。通过对VR全景的技术研究,找到匹配特征点对的关键,结合Infraworks软件自身的特点,总结出在三维模型上建立全景图像的一般方法,使三维模型可以用VR全景快速便捷地表现,拓展了VR全景的领域。
In modern road design,BIM technology is used to build a 3D model on Infraworks,and the model is displayed by VR panoramic technology. The traditional VR panoramic technology is only effective for the actual scene,but can not work on the 3D model. The key point of matching feature points was found based on the technical research of VR panorama. Combined with the characteristics of Infraworks software,we summarized a general method of setting up panoramic images on 3D models. It made the 3D model can be performed quickly and conveniently with VR panorama,and expanded the field of VR panorama.
