"S3DIS"

"S3DIS is composed of five large-scale indoor areas from three different buildings, each covering approximately 1900, 450, 1700, 870 and 1100 square meters (total of 6020 square meters). These areas show diverse properties in architectural style and appearance and include mainly office areas, educational and exhibition spaces, and conference rooms, personal offices, restrooms, open spaces, lobbies, stairways, and hallways are commonly found therein. One of the areas includes multiple floors, whereas the rest have one. The entire point clouds are automatically generated without any manual intervention using the Matterport scanner. It has 12 semantic elements, which are structural elements (ceiling, floor, wall, beam, column, window and door) and commonly found items and furniture (table, chair, sofa, bookcase and board). "S3DIS数据集由来自3栋不同建筑的5个大型室内区域构成，各区域面积分别约为1900、450、1700、870与1100平方米，总覆盖面积达6020平方米。这些区域在建筑风格与外观上展现出丰富多样性，主要包含办公区域、教育与展览空间，以及会议室、个人办公室、卫生间、开放空间、大厅、楼梯间与走廊等常见场景。其中一个区域为多层结构，其余区域均为单层。全部点云数据均通过Matterport扫描仪自动生成，未经过任何人工干预。该数据集共包含12类语义元素，分为结构元素（天花板、地板、墙面、梁、柱、窗户与门）以及常见物品与家具（桌子、椅子、沙发、书架与黑板）。
