Paper Abstract

A method study to improve automatic 3-D data acquisition from stereo images of the human face by using correlation equipment from Kern is presented. Soft tissue morphology can be meas-ured in three dimensions by using close range photogrammetry. The collection of height information in a regular grid pattern was performed automatically utilizing the correlator of Kern DSR-11 analytical plotter. To improve contrast a random point generated pattern was projected onto the patients face. The correlation algorithm used was the "Vertical Line Locus" (VLL). The original Kern program has been modified, and by choosing suitable correlation window size, the number of succesfully correlated points was considerably increased.
