In order to ensure the disaster control during infrastructure construction and operation, a method of tilt photogrammetry of prefabricated buildings using UAV is proposed. A comparative study of the key steps in the 3D construction process of building (structure) was carried out, and a set of 3D morphology construction method based on UAV tilt photogrammetry was proposed, and the key steps were optimized to realize automation and visualization in the process of model construction. The experimental results show that in the application case of a school district, the error of the three directions is distributed between -4 cm and 4 cm, accounting for 74%, and that between -2 cm and 2 cm, accounting for 37%; the root mean square error of the three directions was calculated to be 4.0 cm, 3.8 cm, and 2.8 cm, respectively. In an engineering application case, the error size of the three directions distributed between -4 cm and 4 cm accounted for 74%, and that between -2 cm and 2 cm accounted for 50%; the root mean square error of the three directions was calculated as 2.3 cm, 2.5 cm, and 3.3 cm, respectively. Conclusion. This method can not only obtain high-precision 3D models of urban complex and single buildings, but also meet the requirements of digital city construction for 3D model construction and obtain clear and high-precision digital land surface model.

“…Compared with fixed-wing UAVs and quadrotor UAVs, tilt-rotor UAVs (TRUAVs) have a special structure. By adjusting the tilt angle of the rotors, the TRUAVs enjoy the vertical take-off and landing (VTOL) and fast cruise capability [4]- [7]. As a special kind of TRUAV, a CRUAV has been researched in [8], as shown in Fig.…”

“…Despite the attractive advantages mentioned above, coaxial vehicles like the muFly helicopter require complex mechanisms such as swashplates and stabilizer bars, thus presenting analysis and design challenges. [14][15][16] Note that the coaxial UAV with swashplate mechanism changes the angle of attack of the blades periodically by controlling the tilt angle of the swashplate. 17,18 This enhances the coupling between the system state and the control input in the dynamic model as well as structural complexity and controller design difficulty.…”

This article mainly introduces a design and control method for a new type of portable coaxial dual-rotor unmanned aerial vehicle. The coaxial dual-rotor unmanned aerial vehicle prototype is constructed using three-dimensional computer-aided design software, and its aerodynamic characteristics are analyzed via computational fluid dynamics. A 6-degree-of-freedom nonlinear dynamic model of the coaxial dual-rotor unmanned aerial vehicle is derived by considering the characteristics of coaxial rotors and the downwash airflow. A proportional–integral–derivative tracking scheme including an inner-loop attitude controller and an outer-loop position controller is developed to track the target position and attitude, respectively. Finally, numerical simulations and actual experimental tests are employed to demonstrate the validity of the developed coaxial dual-rotor unmanned aerial vehicle system.
