| Summary: | 碩士 === 國立成功大學 === 機械工程學系碩博士班 === 95 === The purpose of the study focuses on the Client-Server Framework for an optoelectronic human motion tracking system. In the previous study, we have developed a 3D locator. We then propose to connect several (at least 4) 3D locators which are placed around the human body to capture the whole body motion without obstruction. A hub (server) is placed between the PC and these 3D locators (clients). The hub provides clock signals to the clients so that these locators can exposure their CCD simultaneously. For data transmission, we use the method of UART (Universal Asynchronous Receiver/Transmitter) to transfer the data from the motion trackers to the Hub. To further decrease the problem of the occultation of the markers, we construct the motion curves of all the markers and calculate the position of all the markers at the same time slice. Then, we use kinematic and geometry relationship between the markers to get the position of the occultation of the markers if any missing.
