Abstract :
Digital mapping camera is an important tool for modern airborne photogrammetry. Monochromic area CCD which is full frame transfer is selected as image sensor in this paper. Electronic shutter is utilized to eliminate the opening delay of mechanical shutter which will affect the precision of exterior orientation elements acquisition. The equation for calculation displacement of principal point is proposed for TDI forward image motion compensation to compensate principal point shift. Imaging pose control system is designed in order to meet the need for airborne stereo mapping.
