当今高端仿真系统中包含的人体图形模型广泛用于人体工程学分析。男性和女性的身材可以通过输入标准的人体测量尺寸来缩放，例如身高、体重和肢体长度，以表示大范围的身体尺寸。然而，这些比例模型的形状往往是不现实的，特别是对于极端的体型，因为只有相对较少的尺寸被调整。一些软件包具有调整图形以匹配个体体表扫描的能力，但当必须模拟具有广泛属性的个体时，这种能力是不够的。基于对数百名男性和女性的激光扫描的统计分析，我们在Jack人体建模软件中提出了一种新的图形生成能力。利用基于Jack体型模型的模板网格对每次扫描进行拟合，并利用主成分分析和回归建立统计形状模型。该模型被集成在杰克软件中，以创建具有高度逼真的身体形状的杰克数字，可在本地使用所有仿真和分析功能。
Human figure models included with today’s high-end simulation systems are widely used for ergonomic analysis. Male and female figures can be scaled by inputting standard anthropometric dimensions, such as stature, body weight, and limb lengths to represent a large range of body sizes. However, the shapes of these scaled figures are often unrealistic, particularly for extreme body types, because only a relatively few dimensions of the figures are adjusted. Several software packages have the capability of adjusting the figure to match a body surface scan of an individual, but this capability is insufficient when individuals with a wide range of attributes must be simulated. We present a new figure generation capability in the Jack human modeling software based on a statistical analysis of laser scans of hundreds of men and women. A template mesh based on the Jack figure model was fitted to each scan, and a statistical shape model was created using principal component analysis and regression. The model was integrated within the Jack software to create Jack figures with highly realistic body shapes, usable natively with all simulation and analysis features.
