“MPU9250 & MPU9265 calibration 9-DOF Gyro Accelerator Magnetometer Module with Arduino on Unity 3d
A method for calibrating an on-body 9 Degree of Freedom (DOF) Inertial Measurement Unit (IMU) is proposed. The proposed system uses a single 3D position sensor, the earth’s ambient gravity vector, the earth’s magnetic field vector, and a semi-random motion sequence for calibration. The proposed method performs sequential calibration of each of the sensors and transports magnetic field vector values on unity3d to move object 3d (Earth)”
