For the purpose of implementing UAV’s landing on the deck of ship automatically under all-weather,vision-based landing scheme based on cooperative object was proposed.First,considering the atmospheric window、transmission property of infrared irradiation in atmosphere and the impact of the most appropriate temperature corresponding to the optional infrared band on the controlling of the cooperative object’s temperature,8～12 μm was identified as the radiation band of the cooperative object.Then,considering shape of other heat sources on the ship,the cooperative object‘s shape was designed as T.Finally,the cooperative object’s dimensions was decided by Johnson criteria,and the cooperative object was made out,which has a special shape and can radiate specific infrared radiation.The result shows that the average recognition time is 17.2ms using affine moment and can improve the reliability and real-time characteristic of UAV’s autonomous landing dramatically.
