In order to achieve the UAV without GPS guidance and high-precision dynamic landing
a dynamic and autonomous landing system for UAVs with multi-sensor fusion was established.UWB (Ultra Wideband) equipment was used to achieve three-dimensional positioning of UAVs
the landing near the labelwas guided by using position information. Then the visual processing algorithm was designed to quickly and accurately calculate the relative three-dimensional information of the UAV and landing label. Then
after analyzing the dynamic uniform model of the landing tag
Kalman filter was designed to estimate and correct the visual information in the horizontal direction and improve the landing accuracy. Finally
the filtered three-dimensional informations were utilized by the PID controller based on position control to realize the high-precision dynamic autonomous landing control of UAV.The experimental results show that the unmanned aerial machine can be guided to near the landing label and the landing accuracy within 5 cm.UAV in the absence of GPS signal guidance problem is resolved basically
the requirements of high precision dynamic and automatic landing is met.
