Dense 3D pressure discomfort threshold (PDT) map of the human head, face and neck [Dataset]

This dataset contains a dense 3D pressure discomfort threshold (PDT) map of the human head, face and neck of a mixed population (n=28), mapped on an average head model of all the participants. Datasets on nonNormalised and Normalised are available. To aid designers and engineers, this PDT is also mapped on the human head Statistical Shape Model (SSM) (from Principal Component 1 to PC50, ±3σ) built on the CAESAR 3D Anthropometric Database (USA, Italy and The Netherlands, male and female, 18-65y, n=4309). Files are available as *.vtk for further analysis, and as *.obj for further use as reference models for design engineering in e.g. CAD.

本数据集包含针对混合人群（n=28）的头部、面部及颈部的密集三维压力不适阈值（Pressure Discomfort Threshold, PDT）映射图，该映射基于所有受试者的平均头部模型构建。非标准化与标准化数据集均已提供。为助力设计师与工程师开展工作，本数据集的PDT还映射至基于CAESAR三维人体测量数据库（覆盖美国、意大利与荷兰，含18至65岁男女受试者，样本量n=4309）构建的头部统计形状模型（Statistical Shape Model, SSM）上，该SSM涵盖从主成分1（PC1）至主成分50（PC50）的±3σ范围。数据集文件可获取为*.vtk格式以用于后续分析，亦可获取为*.obj格式，用作计算机辅助设计（CAD）等工程设计场景中的参考模型。
