Research on fixed pattern noise de-noising of APS COMS

Abstract

Abstract. Star sensor is an important part of the attitude control of a space vehicle. At the time of image acquisition, CMOS sensors will have some fixed pattern noise which will affect the image capture effects. From the practical application, this article apply the average of de-noising algorithm to eliminate the effects of noise caused by fixed pattern, which can effectively improve the accuracy of image capture, thus helping centroid localization be more accurate.
