扩充现实技术在工程评价方面的应用

Application of Augmented Reality (AR)Technique to the Evaluation of Projects

认为扩充现实 ( Augmented Reality,AR)是计算机领域的前沿课题之一 ,它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 ;与传统的虚拟现实相比 ,它具有更强的真实性 ,大大提高了仿真效率 .首次提出了 AR技术在工程评价方面的应用 ,论证了基于仿射表示的 AR方法及其对工程评价的应用 ,其结果表明 ,AR技术为工程评价开辟了广阔的前景 .

The technique of AR is to place the simulation model of an object (from a computer) in real surroundings (from a digital pick up camera). The authors apply the technique to the evaluation of the schemes of large projects for the first time. In the paper is stated the method of AR technique based on affine structure in detail.Two examples are presented,and their visual results are very well.AR technique can make the real scene of a project to be built present itself before our eyes. The application of AR technique supplies means for the visualization, evaluation and comparison of design schemes of projects. It increases the reliability of the design schemes of the projects and reduces the design cost of them.
