摘要
文中基于准三维模型对惯导系统误差校正的思想,利用摄像机成像系统和捷联惯导系统(SINS)相结合的方法,着重对量测矩阵进行推导。然后,采用离散卡尔曼滤波方法进行导航误差估计,并用估计出来的误差对惯导系统的输出进行修正,在一定程度上提高了导航精度,理论上大大降低了导航成本。
Based on the INS error correction by quasi-three dimensional model, the method of the combination of camera imaging system with SINS to deduce the measurement matrix was utilized. INS error estimation was conducted by discrete Kalman filter to correct INS output. By this method, the navigation accuracy was improved to some extent and theoretically reduced navigation cost significantly.
