| Abstract: | Off-axis TMA optical system, both long focal length and wide-fi eld, can be optimized for optical system of zero distortion, low-fi eld curvature. Off-axis TMA optical system well meet the requirements for optical system of surveying and mapping, therefore recognized for development of aerospace remote mapping camera. This paper gives the present status and development trend of foreign aerospace mapping camera, and discusses the problems of off-axis TMA optical system used in mapping, such as the defi nition of camera inner orientation elements, correction of focal length calculation formula, focusing mode effect of camera principal point position accuracy, system distortion calibration, system stability, and other discussions. |
