基于图像的虚拟现实技术在土木工程领域的应用

APPLICATION OF IMAGE-BASED VIRTUAL REALITY TO CIVIL ENGINEERING

基于图像的虚拟现实 (Image BasedVirtualReality—IBVR)使观察者能够同时看到真实世界以及扩充了真实世界的、来自于计算机模型的信息 ,从而具有更丰富的信息空间。IBVR是计算机领域的前沿课题之一。本文首次提出了IBVR技术在土木工程领域的应用 ,论证了基于仿射变换的IBVR方法及其对桥梁工程的应用。结果表明IB VR为土木工程可视化提供了一个新的好方法 ,具有广阔的应用前景。

The application of image?based virtual reality (IBVR)to the civil engineering is performed in the paper.The IBVR based on affine transformation of four points is derived using the tensor method.The IBVR is a subject in the front of research field.A practical example of application the IBVR to an arch bridge is presented.It is shown that the IBVR technology is a new way for the visualization of civil engineering.
