摘　　要：集成高分辨率多视航空影像与LiDAR数据,以"轮廓提取—3维轮廓生成—3维模型重建"为主要框架,提出一种多视轮廓与LiDAR数据集成的3维轮廓线生成方法、LiDAR数据支撑下改进的分割-合并-成型算法,形成一套新的、系统的3维建筑物模型重建技术方案。该方案可以有效重建结构复杂的3维建筑物模型,相对单纯基于LiDAR的方案,所重建3维模型的准确性与完整性更好、定位精度更高。An approach by integrating multi-view aerial imagery and LiDAR data is proposed for automatically reconstructing 3D building models with precise geometric position and details. It consists of three main steps; building boundary extraction, 3D boundary determination and 3D building model reconstruction. Two new algorithms are proposed：（1） a method on 3D building boundary determination by integrating multi-view 2D boundaries and LiDAR data; （2） an improved split-merge-shape algorithm based on LiDAR data. The results demonstrated that the complex buildings can be reconstructed well by the proposed approach; comparing the approach only using LiDAR data, the constructed 3D models have higher correctness and completeness and have more accurate geometric position.
