SensatUrban

SensatUrbat 数据集是一个城市尺度的摄影测量点云数据集，拥有近 30 亿个丰富标注的点，是现有最大点云数据集的 5 倍于标注点的数量。该数据集由来自两个英国城市的大片区域组成，覆盖了大约 6 km^2 的城市景观。在数据集中，每个 3D 点都被标记为 13 个语义类别之一，例如地面、植被、汽车等。The SensatUrbat dataset is an urban-scale photogrammetric point cloud dataset with nearly 3 billion richly annotated points, which is 5 times the number of annotated points of the largest existing point cloud dataset. It consists of large areas from two UK cities, covering approximately 6 km² of urban landscape. In this dataset, each 3D point is labeled as one of 13 semantic categories, such as ground, vegetation, cars, and so on.
