摘　　要：本文研究由多台小面阵CCD相机构建组合式宽角航空相机的新方法———包括由3台或4台相机组合构建的多相机系统结构,由其分离的各影像转换成等效大影像的数学表达;利用室外和室内近景相机检校场对组合相机系统进行高精度检校的内容、解算方法和检校结果;最后给出了以3相机组合系统装备无人驾驶飞行器(UAV II)进行低空摄影的影像成果。A new method for combining small-sized areal array CCD sensors to make one wide-angled digital aerial photography system is studied and realized inthis paper.The method is to install several small-sized areal array CCD cameras in the way that their perspective projecting centers form a line or a square,with their principal optical axes slanting fixed angle along designed directions.Such installation aims at getting one big frame of image,which is the exact mosaic of group image captured by combined cameras at one time,equivalent to the one taken directly by a wide-angled aerial camera.The system parameters:position relationships between cameras,exact principal distance of each camera and optical distortion parameters of each lens are obtained with high precision through our designed camera calibration method-space resection with several images of calibration field.The research work and experiments in this paper can guide the production of whole wide-angled high-resolution digital camera.
