本研究主要目標為建構一套具有雙重模式之光學三維定位系統(D2000)，將光學式三維掃描與標誌點運動追蹤功能整合於同一硬體架構中。利用其掃描功能，可建立完整人體靜態資料並依標準格式記錄人體結構化之檔案；再利用其運動追蹤功能擷取受測者之標誌點運動，並結合靜態掃描之結構化檔案來建立具真實人體模型，以降低人體靜態與動態資料接續上的難度。本文內容包含系統模組之光學設計、電路實作、組裝、攝影機校正及多模組系統註冊。攝影機校正引入兩種方法，第一種為使用已知三維校正治具計算攝影機參數，並透過最佳化方法精進校正誤差；另一種方法則為利用平面校正治具來求得攝影機參數。最後透過實驗評估靜態掃描與動態追蹤之效能。

The purpose of this study is focused on the development of a dual-mode optical measurement system. In order to decrease the degree of difficulty in integration of static and dynamic data, we combine human motion tracker with human body scanner in one system. It could not only record complete human data and establish a standard human file by scanner but also track the motion of markers on the human body by this dual-mode optical measurement system. The content includes optical design, circuit design, camera calibration and multi-module registration. Two camera calibration methods are introduced in this study. The first method uses a known-shape 3D-jig to compute the camera parameters and employs optimization to improve the accuracy. The second method uses a planar jig to obtain camera parameters by arbitrary orientations. Finally, we evaluate the performance of scanner and tracker by experiments.
