A laser scanning system for the measurement of facial surface morphology

A no contact system based on laser scanning, which records 20 000 facial surface coordinates with a dynamic resolution of approximately 0·9mm in 30s, has been developed for the study of facial changes following facial reconstructive surgery. Individual profiles are recorded with a resolution better...

Description
Summary:A no contact system based on laser scanning, which records 20 000 facial surface coordinates with a dynamic resolution of approximately 0·9mm in 30s, has been developed for the study of facial changes following facial reconstructive surgery. Individual profiles are recorded with a resolution better than 0·5mm. The system is based on the analysis of the output from a video camera which obliquely views a laser line projected vertically onto the face. In order to sample the whole face, the subject sits on a chair which rotates at six degrees per second under computer control. Examples of applications of the system are given.
