中文摘要: 在计算机视觉和计算机图形学中,单视图三维重建是一个很难的问题。为实现基于单幅图像的快速建筑物识别过程,提出了一种可行的、有效的三维重建方法—非完全拓扑分析。首先,对可见部分的轮廓进行分析并提取建筑形象,得到完整的拓扑结构。其次,将分割后的拓扑结构与原始数据库信息进行快速匹配。实验表明,本方法与SSDA图像匹配算法相比,大大提高了计算速度。
Abstract:3D reconstruction from single view is a very difficult problem in computer vision and computer graphics. Much different from method using presently, we proposed a feasible and efficient method of 3D building reconstruction method by using non-complete topological analysis in this paper, which rapidly achieves the process of recognizing architectures based one or two images. Firstly, the outline of visible parts of architectures is extracted from image and is analyzed to get the incomplete topology of architectures. Next, the resulted topology will be divided into different primitive geometries, and these geometries are used to match models in databases finally. Experiments show that our method VS SSDA has better effectiveness.
