3D空间航片纹理源的纹理映射问题

摘要

随着数字三维城市建设的快速推进,传统的纹理获取方法已不能满足快速建模的要求.提出了一种基于航片纹理源的3D空间纹理映射方法,基于摄影测量学相关理论,通过设计算法,实现了建筑物侧面纹理的自动匹配.实验证明,这种方法简单、高效,适用于大面积建筑物3D建模.%With the rapid progress of digital three-dimensional city construction, the traditional texture acquisition method can not meet the requirements of rapid modeling, therefore, this paper presents a 3D space texture mapping method which is based on aerial images and takes it as texture source in order to improve 3D modeling speed. Based on the relative theory of photogrammetry, we achieved the automatic texture matching of the building side through designing algorithm. Experiments show that this method is simple, efficient and suitable for buildings' 3D modeling of large area.
