3D LiDAR and Photogrammetry Scans of a Stilt House in Tai O Village - 2022 - Case 328954

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 328954" 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 denoised using VRMesh Software 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.

本数据集包含一份针对大澳村某棚屋的摄影测量与激光雷达（LiDAR）联合扫描点云文件。该棚屋在研究项目记录中被编号为“案例328954”。研究人员使用徕卡（Leica）BLK2Go型号3D环境扫描仪，仅通过约10分钟的房屋遍历作业即完成本次扫描。本次扫描以高细节度与色彩保真度完整记录了该棚屋的内部空间与部分外部区域的点云数据。为压缩文件体积，研究团队已通过VRMesh软件对扫描数据进行降噪处理。该数据集可清晰呈现该棚屋的实体状态，支持研究者将点云数据解析为房屋建造结构、内部陈设与空间使用情况的文字描述。为保护该房屋住户的个人信息，本数据集实施为期一年的保密期，其开放用途包括建筑数字化保护，以及支撑后续研究以解析该棚屋的实体状态与内部陈设。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）需经审核后方可申请获取。
