Measured pain rating with the FRCM. a Comparison of the pain rating obtained from 3D and 2D imaging depending on the rotational angle of a plaster cast. The pain intensities obtained from 3D images (mean: 0.047, std.: 0.012) is more consistent pain intensity than those from 2D images (mean: 0.196, std. 0.078). b Measured pain intensity obtained from 3D images of human facial expression. The strong expressions exhibit the highest value
