英文摘要	Due to electronic rolling shutter, high-speed large frame complementary mental oxide semiconductor (CMOS) aerial cameras not only suffer from motion blur, but also lead to geometric distortion caused by rolling shutter effect. The conventional method which deals with these two degraded factors separately is very complicated and has a high computational complexity. To address the problems of linear motion and rolling shutter distortion resulting from aerial forward flight, a close relationship is derived between them through analyzing respective mathematical model. Furthermore, a method is proposed to restore double degraded images based on parameter estimation of linear motion. Then an experiment is designed to simulate aerial forward flight in which a CMOS camera controlled by the linear displacement stage imaging at different speed. Experiment results indicate that rolling shutter effect has no influence on the parameter estimation of linear motion. And the Interframe Transform Fidelity of restored images can be improved to about 27 dB. The calculation speed is 3.5 times faster than restoring step by step when obtaining the same good results. , 2015, Chinese Optical Society. All right reserved.
