The system of motion capture based on Inertial sensor

This article describes a complete motion capture solution. The problems of quaternion, rotation of quaternion and coordinate matching are described in detail. This system solves the shackles of wired transmission in the past by wireless transmission, which greatly simplifies the use of the system. In this study, the data collected by the chip is converted into a quaternion, which effectively solves the problem of the universal lock. The data is smoothed by adaptive linear interpolation, and then the final values are coordinate-matched, resulting in a simple operation and accurate motion capture scheme.
