Calculation and compensation for image motion of aerial remote sensor in oblique situation

The forward motion and attitude variation of the aircraft can cause a deviation between the optical axis and the light emitted from the object on the ground,which produces conjugate point movement and image motion on imaging medium.By using the method combining light vector with optical axis revolution,aiming at the translation between object and optical axis and the deviation of the optical axis direction caused by the attitude variation of the aircraft,the relationship between light vector and optical unit vector is obtained,and the mathmatical model for image motion compensation is established.The image motion of remote sensor is analyzed and calculated with measured parameter and the method of image motion compensation is given.The results show that the method integrates forward image motion with attitude image motion,which is easy to calculate and can be applied in the research of aerial remote sensor.
