一种基于TIP技术的场景重建和漫游方法

基于图像的建模和绘制方法与基于传统的几何绘制方法相比有很多优点。但是，在场景几何未知的情况下，要实现单幅图片和图像序列的漫游，难度很大。TIP技术使得在一幅图像中漫游成为可能，但它采用的平面建模方法有很大的局限性。本文在对TIP技术扩展的基础上提出了一种曲面建模的方法。该方法减少了TIP技术的限制，扩展了其适应性。实验结果表明，本文提出的算法是有效的，具有实际应用价值。

Reonstruction of Virtual Environments and Roaming Based on the TIP Technique

Comparing with the traditional approach of 3D model-based rendering with the explicit 3D structure, the approach of image-based modeling and rendering has many advantages, but both fall futile in modeling from one single picture. The TIP technique,which was proposed by Horry in Siggraph 1997, gives us a surprising way to solve this problem. Our methodology in modeling from one picture can be recognized as an extension to TIP. By relaxing the restrictions in the TIP technique, a curve surface modeling method is proposed, which can be used more widely and effectively. The experimental results show that this method is effective and applicable.
