| 摘 要： | 提出了一种基于图像绘制的多边形柱面全景图的虚拟漫游方法。利用普通的手持相机在一个多边形区域内沿某一路径拍摄并拼接多幅全景图,通过基于SIFT的特征点检测来计算深度,用狭缝图像插值来实现整个区域内的平滑漫游。该方法具有采样简单、虚拟场景真实感强,支持连续大范围漫游的特点。

| Abstract: | A new method of virtual walkthrough using image-based rendering with polygonal panoramic mosaics is presented. First, we take pictures and get multiple panoramas with ordinary handhold camera along a route or in a square region. Second, we use SIFT feather points detection to get slim images with depth which can be used in interpolation for the rendering of new view point. The algorithm proposed in this method is very efficient for virtual walkthrough in the large outdoor scene. The construction and rendering process with multiple panoramas is easy to implement and the data capturing is simple without expensive equipments. |
