| 摘要 | In this invention, a high-accuracy jaw motion tracking system and method using the same are disclosed. The jaw motion tracking system of the invention mainly comprises an eyewear facebow static positioning device, a lower jaw dynamic tracking device and a stereo-vision charge-coupled device (CCD) and can provide information regarding the locations and relative movement of lower and upper jaws. The eyewear facebow static positioning device has several passive and active reflective markers. The lower jaw dynamic tracking device equips with a plural of lightweight light emitting devices. Using OpenCV-based self-developed algorithm and post-iterative compensator, the disclosed system can record the dynamical jaw movement with a high accuracy. The disclosed jaw motion tracking system and related method have minimal occlusal disturbance and provide smooth motion-tracking performance. The disclosed system can be used in clinical dentistry. | ||||||
