Relative Position Calibration between Two Haptic Devices Based on Minimum Variance Estimation
In this paper, we propose a new method to estimate the relative positions of multiple haptic devices. As is the case in stereo camera calibration, the accurate measurement of the relative positions of haptic devices is difficult. The proposed method uses the acquired stylus positions of two devices and estimates the relative positions of two devices based on minimum variance estimation. In this method, the data acquisiton process has been improved to allow a large number of data points to be easily acquired. We conducted preliminary experiments to estimate the positions of two devices. The results showed the feasibility and reasonable accuracy of the proposed method.
