A drone comprising: - a camera linked to the drone body, comprising: • a hemispheric-field lens of the fisheye type, pointing in a fixed direction with respect to the drone body; • a digital sensor collecting the image formed by the lens; and • means for automatic control of the sensor exposure; - an inertial unit, adapted to measure the Euler angles (φ, θ, ψ) characterizing the instantaneous attitude of the drone with respect to an absolute terrestrial reference system and delivering as an output current drone attitude data; - extractor means, adapted to define, in said image formed by the lens over the extent of the sensor, the position of a capture area of reduced size; - servo-control means (48, 50, 52), receiving as an input the current drone attitude data and adapted to dynamically modify the position and the orientation of the capture area in said image in a direction opposite to that of the changes of value of the angles measured by the inertial unit; - reprojection means, receiving as an input image data, formed of pixels or macropixels, of a useful area (ZU B) extracted from the capture area and delivering as an output corresponding straightened image data (ZU R), compensated for the geometric distortions introduced by the fisheye lens; and - analysis means, adapted to define a plurality of regions of interest ROI (ROI 1... ROI 9; ROI(i,j)) distributed over the useful area, and to control the dynamic exposure control means as a function of the respective image data contained in the thumbnail from the useful area, in each ROI, and adapted to: - analyse said current image data of the useful area so as to allocate to each of these data aweighting coefficient representative of a probability of belonging to the sky; - dynamically define at each image a segmentation boundary of the useful area between a sky area and a ground area, as a function of the weighting coefficients allocated to each image data; - define two distinct groups of ROIs, for the sky area and for the ground area, respectively; and - control the dynamic exposure control means as a function of the respective image data contained in the thumbnail from the useful area, in ROIs of one of said selected groups. - a camera linked to the drone body, comprising: • a hemispheric-field lens of the fisheye type, pointing in a fixed direction with respect to the drone body; • a digital sensor collecting the image formed by the lens; and • means for automatic control of the sensor exposure; • a hemispheric-field lens of the fisheye type, pointing in a fixed direction with respect to the drone body; • a digital sensor collecting the image formed by the lens; and • means for automatic control of the sensor exposure; - an inertial unit, adapted to measure the Euler angles (φ, θ, ψ) characterizing the instantaneous attitude of the drone with respect to an absolute terrestrial reference system and delivering as an output current drone attitude data; - extractor means, adapted to define, in said image formed by the lens over the extent of the sensor, the position of a capture area of reduced size; - servo-control means (48, 50, 52), receiving as an input the current drone attitude data and adapted to dynamically modify the position and the orientation of the capture area in said image in a direction opposite to that of the changes of value of the angles measured by the inertial unit; - reprojection means, receiving as an input image data, formed of pixels or macropixels, of a useful area (ZU B) extracted from the capture area and delivering as an output corresponding straightened image data (ZU R), compensated for the geometric distortions introduced by the fisheye lens; and - analysis means, adapted to define a plurality of regions of interest ROI (ROI 1...
