摘要
目前无人机航空像片主要采取光学方式进行定位处理,该种方式存在着处理周期长、操作复杂等缺点。针对现状,重点研究了定向解算、影像匹配、粗差检测等关键技术,提出了采用全数字化处理方式实现定位解算,并对系统进行了设计,研制开发了无人机航空像片全数字定位仪。实验结果表明,该仪器具有操作简单、处理周期短、定位精度高等优点。
The optical processing is the current main means on positioning for unmanned aircraft vehiele（UAV） photograph,which has the disadvantage of long processing period, complex operating and so on. Aiming at the problem, firstly, the key technologies are studied including orientation calculating, image matching, error detec- ting. Secondly, the position calculating is achieved by full digital processing. Finally, The full digital positioning instrument for UAV photograph is manufactured. The experiment result shows that the operating is easy, the processing period short, positioning accuracy high.
