Paper Abstract

The wide-field optical system is an important part of lunar exploration image device, and it is applied and researched widely in lunar exploration project. However, with the increase of the field of view, image distortion becomes more serious. In this paper, based on analyzing the basic principles of distortion, a particular geometric distortion correction model is put forward, and a digital correction method is presented, which is novel, practical and also easy to be realized. The experiment proves the validity of the method, and the result show that the distortion rate decreases into 1% from 27% before image correction. This correction method has been applied successfully in a certain exploration imaging system.
