By analyzing the displacement values  the geometrical relationship between the camera and the aircraft is acquired  then relative motion amount between the object and the aircraft is obtained according to the motion and attitude changes. After that  making use of geometrical relationship  we can calculate the displacement variation of pixels within the camera exposure time. Thereafter  taking consider variable motion and non-linear motion as uniform motion in a straight line at the moment of imaging  then the model of the blurring image can be established according to the displacement variation of pixels within the camera exposure time  and fuzzy point spread function in the two-dimensional movement is built. By using Wiener filtering method with the optimal window  the image blurring is eliminated in aerial imaging system. Practice proved that this method can effectively eliminate the image blurring in the aerial imaging system. 2010 IEEE.   Numerical Study of Shock Waves Propagating through Right Angled Multiple Elbows 期刊论文  OAI收割 JOURNAL OF THERMAL SCIENCE, 2005, 卷号: 14, 期号: 3, 页码: 254,257 Kazuyuki KAGE; Mihoko SHIROYAMA; Katsuya ISHIMATSU 收藏  |  浏览/下载：15/0  |  提交时间：2013/03/11 shock wave  multiple elbow  shock diffraction  non-uniform shock  merger of shock
