3D LiDAR and Photogrammetry Scans of a Stilt House in Tai O Village - 2022 - Case 651290

This data includes a point cloud file from a combined photogrammetric and LiDAR scan of a stilt house in Tai O Village. The house is designated "Case 651290" in the research project record. Researchers collected the scan using a single, approximately 10 minute walk-through of the house with the Leica-brand BLK2Go model 3D environment scanner. The scan describes the interior and partial exterior of a stilt house in high detail and color. The scan has been decimated to a voxel size of 5 mm to reduce file size. The data provides clear enough rendering of the physical conditions of the house to allow interpretation of the scan into description of the house's construction, contents, and spatial use. The data is available under embargo of one year to protect the personal information of residents of the house, provided for purposes of digital conservation of the building, and for interpretation of the house's physical conditions and interior contents through further research. More detailed information on the dataset, including the date the scan was conducted, the location of the house, and related interview and survey datasets are available upon reviewed request.本数据集包含大澳渔村某吊脚楼的摄影测量与激光雷达（LiDAR）联合扫描点云文件。该房屋在研究项目记录中编号为"Case 651290"。研究人员采用徕卡（Leica）BLK2Go型三维环境扫描仪，通过单次约10分钟的全屋漫游完成扫描采集。本次扫描以高细节度与色彩精度完整记录了该吊脚楼的内部空间与部分外部区域。为压缩文件体积，扫描数据已降采样至体素尺寸为5毫米。本数据集可清晰呈现房屋的物理状态，支持通过解析扫描数据还原房屋的建造结构、内部陈设与空间使用情况。本数据集设置一年的数据禁运期（embargo）以保护房屋居民的个人信息，其开放授权旨在支持建筑数字化保护，以及通过后续研究解析房屋物理状态与内部陈设。如需获取本数据集的更多详细信息（包括扫描日期、房屋具体位置以及相关访谈与调研数据集），需通过审核后申请获取。
