【摘要】：針對無源環(huán)境下無法采用衛(wèi)星導航定位方式對慣性導航系統(tǒng)的累積誤差進行修正的問題,提出一種采用高精度的矢量道路數(shù)據(jù)進行粗精匹配的導航校正算法。該方法首先通過分析慣導軌跡的特征標示點以及外接矩形,剔除明顯的誤匹配道路和冗余道路,獲取待匹配道路集合;進而,結合ICCP算法具有匹配精度較高,匹配結果較穩(wěn)定的優(yōu)點,完成慣導軌跡位置誤差的補償和校正;最后,根據(jù)匹配方差和歷史匹配軌跡對匹配結果的準確性進行分析和判斷。仿真實驗結果表明,該算法能夠提高慣性導航定位誤差的校正精度,減少在復雜道路交叉口等情況的誤匹配。
[Abstract]:In view of the problem that the cumulative error of inertial navigation system can not be corrected by satellite navigation and positioning mode under the passive environment, a navigation correction algorithm with high precision vector road data for coarse and fine matching is proposed. This method first eliminates the obvious errors by analyzing the characteristic marking points and the external rectangles of the inertial navigation trajectory. The matching road and the redundant road are matched to get the set of matching roads. Then, the compensation and correction of the location error of the inertial navigation trajectory is completed with the advantages of high matching precision and stable matching results with the ICCP algorithm. Finally, the accuracy of the matching result is analyzed and judged according to the matching variance and the history matching trajectory. Simulation experimental results are carried out. It shows that the algorithm can improve the accuracy of inertial navigation positioning error and reduce mismatch in complex road intersection.
