| Abstract: |
| During the process of star navigation, CCD imaging device or infrared imaging device is often used to detect the sky. Due to the continuance exposure time, the star image is always much blur for the fast motion of aerocraft, which will cause great error for image identification and navigation. For solving the problem, Wiener fliter and Radon transform was used to judge and resume the blur image. Good effects were obtained, which provide sound base further star navigation. |
