DRONE WITH A FRONT-VIEW CAMERA WITH SEGMENTATION OF THE SKY IMAGE FOR AUTO-EXPOSURE CONTROL

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. 本发明涉及具有使用天空图像的分割来进行自动曝光控制的前视相机的无人机。无人机包括相机(14)、测量无人机角度的惯性单元(46)、以及递送在由惯性单元测量的角度变化方向相反的方向上动态地位移的经缩减大小的移动捕捉区域的图像数据的提取器模块(52)。该模块分析有用区域的
