[Spatial position of the cranium in craniofacial establishment of identity].
A total of 90 images of male cranes from different groups of horizontal profiling (120 +/- 10 degrees, 140 +/- 10 degrees, 160 +/- 10 degrees) were studied in experiment with the coordinate-controlled complex for turning angle (from the position full face to the right and left by 14 degrees with spacing 2 degrees). Each image was marked according to the system of 18 control points. Precision of the angle fixation was 0.1 degrees. Calculation of the angles of horizontal profiling and turning of the crane were made according to a specially devised program INPUTTING. Statistic processing of the computer data base made it possible to calculate precision rates of marking points and regression equation describing the pattern of cranial control points in turning. It is shown that presicion of the turning angle estimation with reference to horizontal profiling is much higher than without it. Basing on the data obtained a method of zeroing of coordinates of the control points (placing in position for correct scaling of the objects of craniofacial identification) was devised. The method allows greater reliability of the results of personal craniofacial identification.
