摘要
遥感影像目标实时定位的关键是外方位元素的实时获取,在航空遥感平台上加载GPS/INS组合导航系统能够满足这一需求。文中首先给出了基于GPS/INS系统的目标直接定位方法;然后从摄影测量的角度,重点推导了影像内外方位元素对目标定位的误差传递公式;并运用实例验证了公式的有效性。
How to get the external orientation elements of remote sensing images in real time is the key of realtime ground object positioning. To satisfy this requirement, one feasible option is to build an integrated GPS/ INS navigation system on the platform. In this paper, a direct object positioning method is proposed based on the integrated GPS/INS navigation system, then the authors focus on the derivation of the error propagation formula which indicates the influence on the positioning precision from the error of the internal and external orientation elements, and the validation of the formula with an instance.
