碩士 === 國立成功大學 === 機械工程學系碩博士班 === 97 === 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.
