基于LiDAR数据和航空影像的建筑物三维重建技术研究

摘要

在我国大力开展数字城市建设的大背景下,精确地获取建筑物特征点的三维空间信息和重建建筑物三维模型技术是构建城市三维模型的难点和重点,因此在今后相当长的时期内基于融合多源数据的建筑三维重建相关技术研究将是热门的前沿课题。%Under the background of building digital city vigorously around the world,it is difficulty and important to obtain accurate three-dimensional information of building feature points and reconstruct three-dimensional building models while constructing three-dimensional model of the city.So three-dimensional building reconstruction technology based on amalgamating multi-source data will be hot topics at the forefront for a long period of time.
