The Mariner 9 spacecraft was inserted into orbit around Mars in November 1971. The two vidicon camera systems returned over 7300 digital images during orbital operations. The high volume of returned data and the scientific objectives of the Television Experiment made development of automated digital techniques for the removal of camera system-induced distortions from each returned image necessary. This paper describes the algorithms used to remove geometric and photometric distortions from the returned imagery. Enhancement processing of the final photographic products is also described.
“水手9号”宇宙飞船于1971年11月进入火星轨道。在轨道运行期间，两个光导摄像管摄像系统传回了7300多张数字图像。由于返回的数据量巨大，且电视实验有科学目标，因此有必要开发自动化数字技术，以消除每个返回图像中摄像系统产生的畸变。本文描述了用于消除返回图像中几何和光度畸变的算法。还介绍了最终摄影产品的增强处理。
