The present invention provides an intraoral scanner, which comprises an image capture module, a projection module and a gesture detection module. The light emitted by the projection module may pass the reflection lens of the image capture module and irradiate the teeth to be checked within the mouth. The reflected light from the surfaces of the teeth will pass the reflection lens and enter the image capture lens of the image capture module. Then, the imaging member of the image capture module will capture the image and transmit to a modeling unit for obtaining a profile in high precision and enhancing the modeling accuracy. When the intraoral scanner changes the gesture along with the difference of shooting surface of teeth, the gesture detection module will detect the gesture change and transmit to the modeling unit for matching the gesture with the image to be recorded by the recording unit, such that the image may be finished with multi-facet feature matching in a short period of time.本發明係一種口內掃描裝置,其包含一取像模組、一投射模組及一姿態感測模組,該投射模組發出的光線通過取像模組的反射鏡片並照射至口內待測的牙齒,自牙齒表面反射的光線通過反射鏡片並進入取像模組的取像鏡頭,再由取像模組的攝像件擷取影像並傳送至一建模單元,取得精度高的輪廓線並強化建模的精確性,以及該口內掃描裝置隨牙齒拍攝面的不同而改變姿態時,可由該姿態感測模組偵測姿態的改變並傳送至建模單元,取得姿態與影像的配合,供記錄單元紀錄,讓影像能在短時間內完成多面特徵貼合。10‧‧‧框架11‧‧‧基座12‧‧‧組接框13‧‧‧軌道15‧‧‧驅動馬達20‧‧‧投射模組21‧‧‧投射光源22‧‧‧校正鏡片30‧‧‧取像模組31‧‧‧攝像件32‧‧‧取像鏡頭33‧‧‧套筒34‧‧‧反射鏡片40‧‧‧姿態感測模組41‧‧‧電路板
