摘要：A new method for combining small-sized areal array CCD sensors to make one wide-angled digital aerial photography system is studied in this 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
