Image Based Walkthrough: An Approach Using a RelaxingSpidery Mesh with Two-vanishing Points
图像漫游：双灭点的松弛蜘蛛网格算法

A new approach for solving the spidery mesh limits in image based virtual touring , which uses a relaxing spidery mesh with two vanishing points, is proposed in this paper. Comparing with other researches work, this approach can be applied to a wider range of images for walkthrough. We have found that it can tour into the picture which has only one vanishing point, double vanishing point, and multiple vanishing points. The test result also shows that our approach can be effectively applied to the picture which contains vanishing line. In our approach, the interactive work is very simple as the user need only to interactively choose two vanishing points, the background and front object. To avoid the texture distortion, a small block texture mapping technique is used to improve the rendering quality of scene. In the test, different kinds of images are used to show the effectiveness of our approach.
