Three-Dimensional Accuracy of stereophotography technology-based 3D Face scanners: A New Evaluation Method.
Objectives: To evaluate the accuracy of different stereophotography technology-based 3D facial scanners using a Novel evaluation method.
Methods: : A total of 30 patients, plaster facial moulages used in this study. Each plaster facial moulage scanned with the following stereophotography technology-based 3D scanners: 3dMDface System, Facial Insight 3D, SCANIFY. In addition to a high-accuracy Industrial laser 3D scanner (GOM, Capture 3D).
Each 3D scanned image exported into stereolithography binary file format (*.stl) and imported to a sophisticated processing software package (Geomagic® Control™). All the 3D images oriented to the same co-ordinate. In Geomajic, the scans from GOM laser scanner set as Reference and the scans from the other 3D face scanners set as a test. Each test scan was superimposed on the corresponding scan from the GOM scanner, using the best fit superimposing feature. Then the 3D Compare analysis performed.
Results: The respective 3D accuracy of 3dMD, Facial Insight 3D, SCANIFY were 0.54±0.15 mm,
0.68±0.48 mm and 0.61±0.19 mm.
Conclusions: These findings suggested that stereophotography technology-based 3D scanners were accurate, precise, and reliable to record the facial morphology for both clinic and research purposes.
