Abstract: This paper proposes image processing technology and Beidou/SINS compact integrated navigation system, and analyses its performance. The experimental results show that in terms of attitude angle accuracy, the attitude data output by the integrated navigation system in the static state is stable, and the root mean square error is less than 0.6°. In terms of navigation performance, the static positioning error of the integrated navigation system does not exceed 3.5 m, the rotation speed does not exceed 0.12 m/s, and the accuracy is high. Compared with the Beidou satellite, the navigation data consistency of the integrated navigation system is better, the positioning accuracy is less than 5.5 m, and the speed deviation is less than 0.3 m/s. It can be seen that the Beidou/SINS compact integrated navigation system developed in this paper can achieve high precision under dynamic conditions.

Keywords: Beidou satellite navigation; image processing technology; strapdown inertial navigation; compact integrated navigation; digital image processing.
