摘要：
Position-tracking devices have been used in various fields, including medical surgery and augmented reality. In this paper, a wireless optical position-tracking module with a processor that can perform self-3D tracking is developed, and the position coordinates of the cube marker are obtained using a position-tracking algorithm. Software is developed to send position coordinate data to the host computer using a wireless UDP network and make it visible at the host computer. To verify the networking system speed and evaluate the accuracy of the position coordinate data, we conducted experiments using the host computer and a two-axis electronic stage. The results demonstrate a speed of 26.81 ms on average with a frequency of 37.3 Hz. The difference between the moving distance of the actual cube marker and measuring cube marker is 0.764 mm on average, with an RMSE of 0.973 mm. This system enables the installation of the device in any space and permits the use of a wireless network, eliminating the data transmission line and simplifying the configuration. Furthermore, many optical position-tracking modules can be installed to solve the problem where the obstacle blocks the cube marker. © ICROS 2019.
