Franiel00aComputer system for the analysis of facial features based on 3d surface scans.  a377–3823 aDevelopment of 3D scanning techniques provides new possibilities in supporting orthodontics diagnosis. The article describes the implementation and functions of the computer system for facial feature analysis based on 3D surface scans of patient head. The system contains functions derived form traditional facial feature analysis like landmarks acquisition, measurements of distances, inclinations and proportions of the face. Beyond, it enables the analysis of multiple scans, using the registration based on user determined coordinate system.
