Method for measuring anthropometric parameters. When measuring, the coordinate axis of the model is shown in the lower right corner of the subfigure. The light green plane is the 2D X-Y plane, the red annotation in the plane indicates the distance parameter and the black annotation indicates the angle annotation. Three different measurement methods are shown in the three subfigures: (a) Distance parameters aligned with the X-axis in the 2D X-Y plane; (b) Distance parameters measured in the 2D X-Y plane; (c) Angle parameters measured in the 2D X-Y plane. (The subfigures show the measurements of d1, d2, and θ1, respectively).
