Airborne precision image stabilizing method based on dual-mode stabilization mechanism

Focused on instantaneous translation of image sequences and rotation instability problem caused by the flight status of the aerial photography process, this paper proposes a dual-mode stabilization method based on a combination of inertial stability and electronic image stabilization. Among them, this paper uses the improved algorithm based on affine transformation model against the traditional electronic image stabilization which is more difficult to adapt to the shortcomings of the rotation changes based on planar motion model. The algorithm can not only accurately describe the changes in the image sequence, but also effectively eliminate the interference of the rotation, jitter, etc. Experimental results show the method can improve the accuracy of image stabilization and reduce electronic image stabilization processing time, which has broad application prospects in the military and civilian fields.
