Unmanned aerial vehicle (uav) is currently in the process of landing several navigation method, Often using a satellite navigation system as the main way of navigation, But when there is damage of unmanned aerial vehicle (uav) runway, need to use other techniques to solve the automatic landing of uav, project reference to other similar technology, the computer vision based on ground cooperation target is combined with inertial navigation, altimeter under all-weather autonomous uavs, precise landing guidance technology, namely in the landing strip (or road or square) placed on the goal of cooperation, cooperation aims to make use of computer vision recognition, finally realizes the uav autonomous landing guidance precision.In comprehensive analysis of unmanned aerial vehicle (uav) landing requirements and conditions, on the basis of the combination of spectral transmittance and atmospheric window, and finally confirmed through the experiment the far-infrared bands in the visual system for video acquisition system, this study also identified the cooperation target corresponds to the highest temperature range for the spectral radiation efficiency. For the concrete implementation for unmanned aerial vehicle (uav) landing runway recognition based on vision to lay a solid foundation.In cooperative target recognition stage, the first of cooperation target image preprocessing, and then using the traditional moment invariant recognition algorithm, the simulation based on this research the landing direction Angle recognition algorithm based on invariant moment, can satisfy the quick positioning of unmanned aerial vehicle (uav). According to pinpoint the direction of the cooperative target, the landing of unmanned aerial vehicle (uav) direction, at the same time, in accordance with the requirements of uav landing, determine the landing strip and adjust the unmanned aerial vehicle (uav) landing posture, finally complete uav autonomous landing guidance for basic research.
