无人机载双拼相机低空航测系统技术研究

Research on Aerial Survey System Technology of UAV Borne Double Camera Low Altitude

目前国内大多数无人机航测系统所采用的单相机平面精度可达到要求,但高程精度无法满足大比例尺测图要求。本文主要介绍一种无人机载双拼组合宽角相机低空航测系统,其组成结构、双拼组合宽角数码相机原理、数据处理软件,以及利用该系统进行大比例尺测图的生产流程。它与单相机系统的最大不同点是,通过双拼组合扩大了成像系统的旁向视场角,使得在等同航高条件下,航带影像地面覆盖宽度增加一倍,从而达到提高效率的目的。

Single camera plane precision of the majority of the current domestic UAV aerial used by the system can meet the require -ments of, but the elevation accuracy cannot meet the requirements of large scale mapping .This paper mainly introduces a kind of un-manned airborne dual combination of wide angle of Low Altitude Aerial Camera system .Its structure, dual combination of wide angle digital camera principle , data processing software and the use of the system for large scale mapping production process .It is the big-gest difference with the single camera system , the dual combination of extended imaging system next to the viewing angle , the equiva-lent air condition , and strip image ground cover width increase one times , so as to achieve the purpose of improving the efficiency .
