The invention relates to a device and a method of scanning teeth mold with multiple light sources. The device includes a carrier, a calibration board, a first light source module, a first image capturing module, a second light source module and a second image capturing module. The carrier includes a moving mechanism, a vertical rotation mechanism, a horizontal rotation mechanism and a teeth mold fixture. The method includes an initial calibration procedure, a rough scanning procedure, a precise scanning procedure and a repeating computation procedure. The initial calibration procedure includes an origin returning step, a calibration board sampling step, a three dimension module sampling step, a calibration processing step and an initial teeth mold file inputting step. The rough scanning procedure includes a placing step, a rough scanning step and a combination step. The precise scanning procedure includes a sampling step, an analyzing step and an integration step. Thereby, a three dimension teeth mold can be precisely and quickly prepared.本發明係一種多光源牙模掃描裝置及其方法,其中該裝置係包括一載具、一校正板、一第一光源模組、一第一取像模組、一第二光源模組以及一第二取像模組,該載具係包括一位移機構、一垂直旋轉機構、一水平旋轉機構及一牙模治具;該方法係包括一初始校正流程、一粗略掃描流程、一精確掃描流程以及一重複演算流程,該初始校正流程係包括一原點回歸步驟、一校正板取樣步驟、一三維模塊取樣步驟、一校正處理步驟、一匯入初始牙模檔案步驟,該粗略掃描流程係包括一放置步驟、一粗掃步驟、一結合步驟,該精確掃描流程係包括一取樣步驟、一分析步驟、一整合步驟;藉此能夠提供精確且迅速的三維牙模模型。10...框架20...載具21...位移機構211...移動平台212...載台213...運行軌道22...垂直旋轉機構221...載臂23...水平旋轉機構24...牙模治具30...校正板31...第一校正平面32...第二校正平面40...第一光源模組41...第一光源發射器50...第一取像模組51...第一攝像鏡頭60...第二光源模組61...第二光源發射器62...分光鏡63...全反射鏡70...第二取像模組71...第二攝像鏡頭
