Abstract

The use of a laser scanning system for human craniofacial mapping has gained considerable interest recently as the system is non-contact and has proved to be very efficient in capturing a vast amount of accurate spatial data. Even though it is efficient and accurate, there is still a need for a thorough evaluation to identify the important technical factors which may affect the accuracy of the system for craniofacial mapping. The paper discusses the tests and the results of evaluating the Minolta VI- 910 3D laser scanning system for capturing craniofacial surface data. The research shows that factors to be considered for craniofacial mapping are: scan distance, camera focal length, laserbeam intensity, scanning resolution, convergence angle, and the number of overlapping scans.
