A light-sectioning technique for contouring and measuring a child's face.
A contouring device for measuring the face (Cobb, 1972) was adopted and developed to make it suitable for use with children. Modifications were made to overcome incomplete facial coverage and lack of common head orientation by incorporating a method of optical head positioning which had been invented during the assessment of a stereophotogrammetric technique (Ainsworth and Joseph 1976). The precise alignment of a series of exposures with a common datum enables a set of contour maps to be processed by computer to produce three-dimensional measurements and sections of the complete face.
