Abstract

In dentistry, precise 3D measurement of oral structures is essential for various clinical processes, including implant, orthodontic, and prosthetic fabrication. High-precision commercial intraoral scanners have been developed for this purpose, but the complex nature of the oral cavity presents the problem of blind spots. To address this issue, repetitive imaging is required, which increases imaging time. To address this issue, this study proposes a prototype mirror-based stereo intraoral scanner combining a single camera and a mirror. The proposed intraoral scanner acquires stereo images from different viewpoints in a single shot, captures a wide area, and estimates relative depth by analyzing the deformation of the fringe pattern light projected from the projector. Experiments conducted on dental models confirmed the proposed intraoral scanner's ability to function as an intraoral scanner by reconstructing the 3D model. Therefore, the proposed intraoral scanner is expected to offer a superior alternative to existing devices in terms of imaging efficiency.
