3D LiDAR and Photogrammetry Scans of a Stilt House in Tai O Village - 2022 - Case 478523

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 478523" 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一处高脚屋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「案例478523」。研究人员采用徕卡（Leica）BLK2Go型号3D环境扫描仪，通过单次约10分钟的全屋遍历完成扫描作业。本次扫描以高细节与色彩精度完整呈现了该高脚屋的内部空间与部分外部区域，并已通过降采样处理至5毫米体素大小以缩减文件体积。本数据集可清晰还原该房屋的实体物理状态，支持通过对点云数据的解读，分析其建筑结构、内部陈设与空间使用情况。为保护该房屋住户的个人信息，本数据集设置为期一年的保密期限，仅可用于该建筑的数字化保护，以及通过后续研究解读其实体状态与内部陈设内容。如需获取本数据集的更多详细信息（包括扫描实施日期、房屋具体位置，以及相关访谈与调研数据集），可通过审核后提交申请获取。
