Design Of Aerial And Horizontal System Of Unmanned Aerial Vehicle Based On Arduino And Labview

UAV is the unmanned aerial vehicle which is controlled by the airborne computer program or the remote communication control of the ground station system. Take aerial photography by UAV has some prominent advantages like takeoff landing site constraints small,remote sensing platforms easy transition,shooting images clear and so on.So it has been widely used in the field of national ecological environment protection, mineral resources exploration, marine environment detection, crop growth monitoring and yield estimation, urban planning, the cause of national defense, film and television manufacturing and others.In the process to achieve the above functions, the aerial platform as the UAV aerial system is an important part, its stability and intelligence will influence the whole system to achieve the effect. By adjusting the aerial platform attitude, you can expand the range of the aerial photography scene, aerial platform stability and accuracy will affect the screen shot of the quality. The design of innovative ideas to the whole process by the aircraft aerial photography and aerial PTZ control personnel who collaborate on, both to ensure the safety of the aircraft during shooting, but also to make a more detailed picture shoot, shoot more flexible.The main contents and results are as follows:(1) Analysis of the related technologies involved in the system platform. Including: the pulse width modulation technology, the steering engine constitution and the driving principle,the calman filter and the complementary filter principle, the gyroscope and the accelerometer principle, the quaternion, the SSL safety certificate and so on.(2) Introduced the module in the system of aerial PTZ. First it introduced the working principle of the whole aerial system, and then each module selection. In which control module is used in open-source development board Arduino UNO R3, attitude measuring module 9-axis motion processing sensor-MPU6050, the PTZ biaxially architecture, as well as PTZ drive module and image acquisition module.(3) PTZ system hardware programming. First of all, collecting the sensor data, by the relation between Quaternion and Euler angles, find attitude solution about aerial PTZ; Then,make a comparison between kalman filter algorithm and complementary filter algorithm, take the best as the final project; At last,choose the modes base on the order of ground station,combining aerial PTZ attitude data to drive servo modules.(4) The design of the ground monitoring and control system. NI LabVIEW2014 is used as software development environment, design modules: aerial video collection module, data acquisition module, aerial PTZ posture display module, web publish module.In this article, the design of aerial PTZ system achieved video collection and display; more work modules such as: the follow-up mode, the balance hold mode, the active control mode,enhanced flexibility when the aerial shooting scene; what is more,the design of the ground upper computer program can be used to the remote acquisite and display PTZ attitude data and aerial video, which improving the timeliness of information.
