Landmark measurement of human skull

The landmark measurement of human skull is fundamental to geometric morphometry of palaeoanthropology. The landmarks are geometry points which can describe anatomically the homology of species group. They play an important role in palaeoanthropology. A structured-light based method is used to measure and make the 3D digital model of skull. The distances between all pairs of landmarks and interior angles from triangulations of the landmarks can be measured fast and accurately by the digital model. Other important geometric parameters of the skull, such as curvature, surface area, volume can also be measured. In order to validate and certificate the proposed method, 9 standard balls, which are embed at the landmarks, are measured by using Coordinate Measuring Arm (CMA). The experiment shows that the measuring errors of the distances and angles are less than 0.08 mm and 5' respectively.
