摘 要：According to the limited accuracy of the current MEMS inertial sensors,the motion displacement method obtained by direct acceleration of the second integration to will bring large errors,this paper presents an motion tracking solution method for tracking three-dimensional arm movement,by changing three-dimensional arm motion into the translational tracking of the plane,complementary filter for multi-sensor data fusion for data integration and correction is designed and the translational tracking method is introduced detailed,The experimental results show that the proposed method can improve tracking accuracy and stability in arm writing motion without noticeable drift.
