真实的世界领域的虚拟表示越来越多地被用于各种不同的应用，如城市规划，人员培训，仿真等，尽管对这种逼真的3D表示的需求不断增加，它仍然是一个非常困难的，往往是手动的过程。在本文中，我们解决的问题，创建照片真实感的三维场景模型的大规模地区，并提出了一个完整的系统。所提出的系统包括两个主要组成部分：（1）采用全自动技术直接从光探测和测距（LiDAR）数据中提取和生成高保真几何模型的重建管道，以及（2）通过融合来自多个光学传感器资源的信息来生成高质量照片真实感纹理的灵活纹理混合技术。结果是真实世界的大规模区域（城市大小）的照片般逼真的3D表示。我们已经用许多城市规模的数据集对所提出的系统进行了广泛的测试，这证实了该方法的有效性和鲁棒性。报告的结果验证了该系统是一个一致的工作流程，允许非专家和非艺术家快速融合航空LiDAR和图像，以构建照片逼真的3D场景模型。
Virtual representations of real world areas are increasingly being employed in a variety of different applications such as urban planning, personnel training, simulations, etc. Despite the increasing demand for such realistic 3D representations, it still remains a very hard and often manual process. In this paper, we address the problem of creating photo realistic 3D scene models for large-scale areas and present a complete system. The proposed system comprises of two main components: (1) A reconstruction pipeline which employs a fully automatic technique for extracting and producing high-fidelity geometric models directly from Light Detection and Ranging (LiDAR) data and (2) A flexible texture blending technique for generating high-quality photo realistic textures by fusing information from multiple optical sensor resources. The result is a photo realistic 3D representation of large-scale areas(city-size) of the real-world. We have tested the proposed system extensively with many city-size datasets which confirms the validity and robustness of the approach. The reported results verify that the system is a consistent work flow that allows non-expert and non-artists to rapidly fuse aerial LiDAR and imagery to construct photo realistic 3D scene models.
