论文摘要
在本文中，我们介绍了我们的工作流程，以自动重建基于2D构建多边形和LiDar Point Cloud的3D构建模型。该工作流以不同级别的详细信息（LOD）生成模型，以支持一个一致的来源的不同应用程序的数据要求。在算法改进的情况下，或者如果新的输入数据可用，则非常关注工作流程鲁棒，以迅速运行新的迭代。重建数据的质量在很大程度上取决于输入数据的质量，并以几个步骤进行监视。已经开发了一个3D查看器，以查看和下载不同格式的不同LOD的公开可用的3D数据。工作流程已应用于荷兰的所有1000万个建筑物。新输入数据可用后，将更新3D服务。
In this paper we present our workflow to automatically reconstruct 3D building models based on 2D building polygons and a LiDAR point cloud. The workflow generates models at different levels of detail (LoDs) to support data requirements of different applications from one consistent source. Specific attention has been paid to make the workflow robust to quickly run a new iteration in case of improvements in an algorithm or in case new input data become available. The quality of the reconstructed data highly depends on the quality of the input data and is monitored in several steps of the process. A 3D viewer has been developed to view and download the openly available 3D data at different LoDs in different formats. The workflow has been applied to all 10 million buildings of The Netherlands. The 3D service will be updated after new input data becomes available.
