Abstract
Objective To design a craniofacial measurement technique based on 3D laser scanning and to verify the system feasibility by comparing with direct manual method. Methods Twenty-eight volunteers were scanned from three directions by 3D laser scanner, including front, left side and right side. After generating these three 3D face images, the preprocessing was conducted, such as the removal of dead pixels and filling of the holes. Then these three images were merged to build a completed 3D face model. Then the Euclidean distance, geodesic distance, angles and ratios of all the items were measured by 3D measurement software 3D-FACE VIEWER developed by ourself. And the results were compared with direct manual measurements. Results The statistical difference between direct manual measurement and 3D measurement was not obvious. The error of 49 items among 56 Euclidean distance measurements and 7 items among 17 geodesic distance measurements were less than 2~3 mm. Conclusion The craniofacial measurement by 3D laser scanning is effective. The software 3D-FACE VIEWER is ideal for craniofacial measurement and worth of promotion.关键词
