摘　　要：运用图像导航原理,设计并实现了一套飞机图像导航数据库系统。系统将导航所需的信息和若干地区的地面图预先存放在数据库中的特定位置。用户只需在系统的可视化界面中进行少量的操作,该系统就能够在飞机航行的过程中实时地显示拍摄到地面图像,并将该图像与数据库中的相关图像进行特征匹配,从而获取并提供给用户飞机当时的位置、航速快慢及航向误差等导航信息。By the principle of the image navigation, in this paper, a suit of image navigation database for airplane was designed and realized. The system put the information which the navigation need and ground images of some regions into the special position of the navigation database. The users just need a little operation in visual interface, then the system can show the ground images which were shotted in airplane during the navigation, and match characteristics between this image and database images. Consequently, the system can provide users navigation information such as location, speed and direction error of the airplane.
