| description | According to the characteristics of DMI with high-precision position information, a navigation method combines DMIs with GPS and IMU is proposed in this paper. Firstly, the prototype system architecture is presented and its operational principle is discussed. Secondly, some key technologies are studied, which include integrated organization method of DMIs and road net data, the position method based on DMI matching with real-time image and the federal Kalman filter model with DMI, GPS and IMU. Finally, experimental results show that the proposed method can counteract GPS signal's unlocking problem and the inertial component's divergence for its error accumulation with time in a vehicle navigation system, whose positioning accuracy and robustness are improved in complex environment. |
