METHOD AND DEVICE FOR ALIGNING COORDINATE OF POSITION DEVICE WITH COORDINATE OF IMU

An alignment method is provided. A first 3D position and a first IMU calculation 3D position of a position object with an IMU is determined when the IMU enters a steady state. A second 3D position and a second IMU calculation 3D position of the position object is determined when the IMU exits the steady state. A first relative vector is determined based on the first 3D position and the second 3D position. A second relative vector is determined based on the first IMU calculation 3D position and the second IMU calculation 3D position. A rotation matrix is determined based on the first relative vector and the second first relative vector. A coordinate system of the position device is aligned with a coordinate system of the IMU based on the rotation matrix. An electronic device and a non-transitory computer readable storage medium are also provided.
