Abstract: The measurement installation comprises a measurement computer system comprising: an identification system (19) that identifies a region of interest on a plane image; a pairing system (20) that determines on each plane image the two-dimensional coordinates of an anatomical point by searching for correlation between the region of interest and a corresponding zone on each other image; and a calculation unit (21) that determines the three-dimensional coordinates of the anatomical point of the individual in the measurement space on the basis of the two-dimensional coordinates and of a relationship obtained by calibration.
