Consumer UAV Inclining Photography Route Planning And Ground Station Research

Tilt photography technology can reconstruct the scene's real three-dimensional model by acquiring texture and structure information in different directions.This technology makes up for the insufficiency of low-altitude remote sensing technology that can only obtain the top information,and realizes the three-dimensional analysis and storage of the ground object information.Inclination photography technology often uses drones or small people-carrying aircraft to capture images with a five-lens camera in the early days.The captured images have high resolution and rich information,but their equipment purchase and use costs are high and the airspace application cycle is long.Problems such as difficulties in examination and approval have limited the use of the technology.With the availability of multi-rotor drones,the cost of tilt photography has been significantly reduced,and tilt photography has gradually moved toward modeling tasks in small-area scenes.In recent years,the rapid rise of DJI has brought consumer-grade drones to people's perspective.This type of drone has been rapidly applied in various industries with excellent mobility and excellent stability.At present,some scholars have attempted to apply small-scale consumer UAVs in the tilt photography industry,and have achieved satisfactory results through experiments.However,few scholars have conducted research on the design planning of tilted photography routes for consumer-class drones.The structure of consumer-class drones on the market is mostly quadrotor.The reason for this is that four-rotor UAVs have the characteristics of vertical takeoff and landing capability,hovering,simple operation,and structural stability.This paper firstly analyzes its structure and flight performance deeply,and realizes its simulation in one-dimensional to three-dimensional space through Matlab.Through experiments,we can understand the flight trajectory that can be completed by the quadrotor UAV and its flight capabilities,and collect a large amount of basic data for the design and planning of future routes.After comprehensive analysis of the performance of consumer-class drones,this paper believes that consumer drones can best be used in the construction of complex structures,structures,or small-scene tilt photography tasks.Then the article classifies the common small-scale scenes and features,and proposes different route planning methods based on the classification.The specific routes can be divided into full coverage routes,surrounding routes,vertical routes,and contour routes.Thirdly,in order to achieve efficient and stable tilt image acquisition,an Android-based drone tilt photography ground station was designed and programmed.This ground station can drive drones to automatically perform tilt photography work according to planning tasks,significantly reducing the tilt.The difficulty and workload of photography technology.To verify the feasibility of designing routes and whether the ground stations are stable and reliable,route planning and modeling experiments were conducted on the experimental site for a variety of characteristic buildings and scenarios.The analysis of modelling effects and accuracy proved that both routes and ground stations are feasible.,And combined the use of routes in the experiment,to achieve a sophisticated model of complex structure modeling,improve the ability of consumer-level drone tilt photography and product accuracy.
