摘要:
    无全球定位系统下高精度定位与导航是飞行器实现自主侦查、巡航与打击的关键。视觉导航具有被动、低成本、能避免累积误差等优点。视觉导航与惯性导航融合更能够发挥出各自的优势,达到高精度定位的目的。总结了异源图像匹配辅助惯性导航的飞行器定位技术的发展历程; 从相机-惯导标定技术、异源图像匹配、姿态解算、数据融合和后端优化五个方面详细阐述了异源图像匹配辅助惯性导航的飞行器定位的关键技术; 指出了基于深度学习的异源图像匹配与惯性导航两种无源定位组合导航系统融合技术等四个未来可能的发展方向,可为实现异源图像匹配辅助惯性导航飞行器定位技术提供参考。

Abstract:
    High-precision positioning and navigation in GPS(global positioning system) denied environments is a key technology for aircraft achieving autonomous scout, cruise, and strike. Vision navigation has the advantages of passive-type, low cost, and avoidable accumulated errors avoidable, etc. The fusion of vision and inertial navigation can give full play to their advantages and achieve the purpose of high-precision positioning. Firstly, the development of aircraft positioning technology based on multi-modal image matching assisted inertial navigation was summarized. Then this technology was elaborated in five aspects:the vision-internal calibration, multi-modal image matching, attitude algorithm, data fusion, and back-end optimization. Finally, four possible future directions were proposed as follows, two types of passive positioning combined navigation systems based on deep learning, multi-modal image matching and inertial navigation. The four possible future directions provide a reference for realizing multi-modal image matching assisted inertial navigation aircraft positioning technology.
Key words:  multi-modal image  image matching  integrated navigation  aircraft positioning
