室内虚拟实景空间的自由漫游

Walking Freely in Image-based Virtual Space of Indoor Scenes

在基于图象的虚拟实景空间中自由漫游是目前虚拟现实领域研究的热点 .同心圆法是解决这个问题比较好的方法 .但是这个方法只解决了柱面投影的问题 ,用户在垂直方向的视域是固定的 .而在室内环境中漫游 ,用户需要进行俯视和仰视 .为此 ,我们扩展了同心圆法 。

The important research fields of virtual reality is how to walk freely in the image based virtual space. Concentric mosaics is a good method to this problem. But it implements the cylindrical panorama, and the vertical of field is fixed. When users walk in indoor scenes, they need look down and look up. Concentric mosaics can not do this, so we extend it and use consphericial mosaics to increase the range of view.
