3D LiDAR and Photogrammetry Scans of a Stilt House in Tai O Village - 2022 - Case 853147

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 853147" 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栋吊脚楼的摄影测量与激光雷达（LiDAR）联合扫描点云文件。该房屋在本次研究项目的记录中编号为「案例853147」。研究人员采用徕卡（Leica）BLK2Go型号三维环境扫描仪，通过单次约10分钟的全屋步行扫描完成了数据采集。本次扫描以高细节度与色彩保真度完整记录了该吊脚楼的内部空间与部分外部结构。为压缩文件体积，已将点云数据降采样至5毫米体素尺寸。该数据集可清晰还原房屋的物理现状，支持通过解读扫描结果分析其建造结构、内部陈设与空间使用方式。本数据集设置为期一年的保密期限，以保护该房屋住户的个人信息，其开放用途包括该建筑的数字化保护，以及通过后续研究解读房屋的物理现状与内部陈设。如需获取该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），需提交审核申请并经审核通过后方可获取。
