Use of shadow-speckle correlation method for 3D tooth model reconstruction.
This study presents a method of using shadow-speckle correlation to reconstruct a 3-dimensional (3D) tooth model. Compared with other methods based on laser or optical geometric measurements, the shadow-speckle method overcomes their limitations by using a digital image correlation to reconstruct a 3D tooth model. Using plaster models 4 times the normal tooth size showed that the accuracy of the reconstructed model was estimated at roughly 30 microm, which potentially could be used in direct intraoral applications.
