摘要:

离轴三反光学系统可以同时兼顾长焦距与大视场, 可以优化为零畸变、低场曲的光学系统, 很好地满足了测绘对光学系统的要求, 被公认为航天遥感测绘相机的发展方向。本文阐述了航天测绘相机的现状和发展趋势, 对离轴三反光学系统应用于测绘的相机内方位元素定义、焦距计算公式的修正、调焦方式对主点位置精度的影响、系统畸变标定以及系统稳定性等问题进行讨论为中国自主获取高分辨率、高精度的测绘数据提供了技术参考。

Technology of off-axis TMA aerospace mapping camera
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.
