Method for field fixed point zero-dead-zone autonomous soft landing of subminiature unmanned rotor aircraft

The invention relates to a method for field fixed point zero-dead-zone autonomous soft landing of a subminiature unmanned rotor aircraft. According to the method, a landing system is started and switched, a landing area is searched, an attitude sensor measures attitude positions of a small unmanned aircraft, and a visual sensor collects target information of a camera; the attitude position information and the target information undergo operation processing according to a set input relationship of eyeball compound motion after being subjected to corresponding A / D conversion and digital filtering, then, the relative deviation between a tracking object and the optical axis of the camera can be obtained, and corresponding scale conversion is carried out; the processed information serves as a control law of an airborne platform controller and respectively controls airborne platform motors, and therefore properties of the eyeball compound motion can be achieved. By means of the method, an airborne platform can be adjusted in real time and autonomous tracking on suspicious motion targets by the unmanned aircraft at a jolting environment can be achieved according to the position information of the tracked motion targets and the attitude information of the unmanned aircraft, and a certain stabilizing effect on tracking images can be achieved.
