Abstract

The detection of anatomical landmarks on the body surface measured by rasterstereography is based on the analysis of surface curvatures. Landmarks such as the vertebra prominens or the lumbar dimples are localised at points of maximum convex or concave curvature. It is shown that the accuracy (reproducibility) of landmark localisation correlates with the magnitude of local curvature. This finding makes it possible to estimate the accuracy of a landmark a priori from a single record, instead of determining the statistical scatter from a large number of records taken in the same posture.
