Abstract
A detection system comprises an analysis unit for analyzing successive images generated by a monitoring sensor to determine in an image a position of an axis representative of the displacement of the aircraft between two successive images, the so-called real position, a computation unit for computing, on the basis of data relating to a displacement of an aircraft between the generations of these two images and of the positioning of the monitoring sensor on the aircraft, a position in an image of an axis representative of the displacement of the aircraft, the theoretical position, an estimation unit for estimating the angular disparity between the real position and the theoretical position, and a comparison unit for comparing this angular disparity with at least one predefined tolerance value so as to detect a misalignment when this angular disparity is greater than this tolerance value.
