Embodiment Construction
[0034] Such as figure 1 As shown, the hybrid shake correction method for UAV video acquisition provided by this embodiment begins with step S1, obtaining a pre-acquisition image from the UAV video image. In this embodiment, the video images collected by the drone are transmitted to the cloud storage, so the pre-collected images can be obtained in the cloud storage. However, the present invention does not impose any limitation on the storage or transmission methods of drone images.
[0035] After obtaining the pre-acquisition image, the Kalman filter is used to estimate the jitter parameters. The Kalman filter is a small and flexible algorithm. A large number of experiments have proved that the Kalman filter is used to process the pre-acquisition image of the UAV, which can well describe the inter-frame motion of the video image formed by the shake of the airborne camera. The small and flexible algorithm makes the hybrid jitter correction method for UAV video acquisition prov...
