Automatic positioning method of UAV ground based on satellite image matching
The UAV reduces the flight altitude to save time or expand the range,resulting in the decrease of the aerial phase amplitude and insufficient predicted overlap with the real position.To this end,this paper studies the automatic 3 d target positioning method of inspection UAV based on satellite image matching.Firstly,UAV camera attitude data is acquired to provide the basis for subsequent processing;then convert 3 D target information,extract 3D target features and deeply analyze UAV images;finally,use satellite images to match the UAV and satellite images to achieve automatic positioning.The experiments show that the localization method is better than the comparison method and has high accuracy and stability.
