Abstract
The drone comprises a camera () having a rolling shutter digital sensor which sends video data (l) line by line. An inertial unit () sends a gyrometric signal representative of the variations in attitude (φ, θ, ψ) of the camera at a given instant. An image processing module () comprising an anti-wobble module receives the video data (l) and the gyrometric signal as inputs, and outputs video data processed and corrected for artifacts introduced by the vibrations of the motors of the drone. A complementary filtering module () applies a predetermined compensating transfer function to the gyrometric signal at the input of the anti-wobble module, which transfer function is an inverse transfer function of the frequency response of the gyrometric sensor of the inertial unit.
