Application Of Data Fusion Technology In UAV

The research of UAV has been a hot research topic both at home and abroad.The UAV has many advantages,such as its good maneuverability,survivability,and no casualties.So its application is very extensive,the prospect is immeasurable.But because of China's study on UAV started late,is still in the primary stage,and the more expensive the price of its manufacturing,leading to the present only has the application in the military,to make the UAV is used in the civil field,we need to continue to study the UAV,this paper has also emerged.The control of UAV is the most important,and it is difficult to control the altitude and attitude,Firstly,this paper introduces some common coordinate system of UAV,and then introduces the related sensors,including sensor and attitude sensor,The principle and error sources are analyzed.Then,the information fusion technology is introduced,including the fusion theory,in which the high degree of fusion is made by Calman weighted fusion,and the fusion of the attitude angle is based on the BP neural network.In the practical application of information filtering through Calman after fusion and BP neural network fusion attitude angle data analysis showed that after the data fusion,has been greatly improved in stability and accuracy,so as to support this view,also confirms the superiority of information fusion technology.
