DRONE WITH FORWARD-LOOKING CAMERA WITH SEGMENTATION OF THE IMAGE OF THE SKY IN ORDER TO CONTROL THE AUTOEXPOSURE

The drone comprises a camera (14), an inertial unit (46) measuring the drone angles, and an extractor module (52) delivering image data of a mobile capture area of reduced size dynamically displaced in a direction opposite to that of the variations of angle measured by the inertial unit. The module analyses the image data elements of the useful area to assign to each one a weighting coefficient representative of a probability of belonging to the sky, and defines dynamically a boundary of segmentation (F) of the useful area between sky and ground as a function of these weighting coefficients. Two distinct groups of regions of interest ROIs are defined, for the sky area and for the ground area, respectively, and the dynamic exposure control means are controlled as a function of the image data of the ROIs of one of these groups, in particular by excluding the ROIs of the sky area.
