Zeitview Rooftop Geometry (ZRG) 数据集
收藏资源简介:
ZRG数据集是由德克萨斯大学圣安东尼奥分校和Zeitview合作创建的大规模住宅屋顶理解数据集,包含超过20,000个美国住宅物业的屋顶检查数据。数据集内容丰富,包括高分辨率RGB正交马赛克、数字表面模型(DSM)、3D屋顶几何线框和3D彩色点云。创建过程涉及使用高分辨率相机无人机进行系统化数据采集和后处理,生成高精度地理参考正交马赛克和DSM。该数据集主要应用于自动化屋顶分析,如屋顶轮廓提取、单目高度估计和平面屋顶结构提取,旨在提高屋顶检查的效率和准确性,降低人工成本。
The ZRG Dataset is a large-scale residential roof understanding dataset jointly created by The University of Texas at San Antonio and Zeitview. It contains roof inspection data for over 20,000 residential properties across the United States. The dataset features rich content, including high-resolution RGB orthomosaics, Digital Surface Models (DSM), 3D roof geometric wireframes, and 3D colored point clouds. Its creation involves systematic data collection and post-processing using high-resolution camera-equipped drones, generating high-precision georeferenced orthomosaics and DSMs. This dataset is primarily applied in automated roof analysis tasks, such as roof outline extraction, monocular height estimation, and flat roof structure extraction, aiming to enhance the efficiency and accuracy of roof inspections and reduce labor costs.
