Zusammenfassung: | The invention provides a rotary-wing drone provided with a video camera supplying stabilised image sequences. The drone (10) comprises a camera with a hemispheric fisheye lens field-type pointing in a fixed direction (A) relative to the body of the drone. A capture zone of reduced size (36) has been derived from the image formed by this lens (42), the positioning of this zone being function of signals delivered by an inertial measuring Euler angles characterizing the attitude of the UAV compared to an absolute landmark. The position of this area is dynamically changed in one direction (44) opposite of the changes in attitude (38) of the drone detected by the inertial unit. Raw pixel data is then processed to compensate for geometric distortions introduced by the fisheye lens on the image accumulated in the capture zone area. |
