Mono Temporal Disaster City 3D Dataset (C3DO)

C3DO is a 3D point cloud reconstruction of concrete buildings, with an emphasis on damaged façades. It was generated by reconstructing a 4.5-acre region in the Disaster City® facility using a Terrestrial Laser Scanner system. This dataset consists of a total of 376,006,839 points that were captured with a precision of 5 significant digits (up to 10-5 m). XYZ coordinates of each point including the corresponding RBG value to represent the texture are published in the “C3DO.txt” file. Individual panels in the dataset are manually delineated and points are rounded to 10-3 m, followed by the deletion of duplicate points. XYZ coordinate data are saved based on the panel ID in the sub-directories with a name corresponding to the building they are mounted on. They are presented in the “CompletePanels” sub-directory of the “PanelsXYZ” directory. Following this, individual points in the sampled panels are labeled as either damaged or undamaged. Data annotations are performed manually by visual interpretation. The damaged points are shared based on the panel ID in the “DamagedPoints” subdirectory of the “PanelsXYZ” directory.

C3DO是一个面向混凝土建筑的三维点云重建数据集，其研究重点为受损外立面。该数据集通过采用地面激光扫描系统（Terrestrial Laser Scanner），对灾难城®（Disaster City®）设施内一片4.5英亩的区域进行重建而生成。本数据集总计包含376,006,839个点云数据，采集精度达5位有效数字（最高可达10^-5米）。每个点的XYZ坐标及对应的RGB纹理值均发布于"C3DO.txt"文件中。数据集中的单个板件均经人工勾勒，且点云坐标被四舍五入至10^-3米，随后移除了重复点云。基于板件ID的XYZ坐标数据被存储于以所属建筑命名的子目录中，这些子目录位于"PanelsXYZ"目录下的"CompletePanels"子目录内。在此基础上，采样得到的板件中的单个点会被标记为受损或未受损。数据标注通过人工目视解译完成。受损点云数据以板件ID为索引，存储于"PanelsXYZ"目录下的"DamagedPoints"子目录中。
