In order to solve the problem of image blurring due to the image motion which results from the aircraft's motion
attitude changes
and the relative motion of the camera and aircraft firstly
we install linear displacement transducer on the four shock absorbers. 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.
