Embodiment 1
[0051] like figure 1 , figure 2 as well as Figure 5 As shown, the fixed-wing UAV provided in this embodiment includes a flight platform 1 , a tilt imaging system 2 , a flight control system 3 and an onboard power supply system 4 , and the flight platform 1 is used to execute the flight control instructions of the flight control system 3 , the tilt imaging system 2 is used to execute the stabilization control command and the shooting control command of the flight control system 3, and the flight control system 3 is used to communicate with the ground control station 5 and send control commands, which is the control center of the fixed-wing unmanned aerial vehicle, The onboard power supply system 4 is used to supply power to all electronic devices in the flight platform 1 , the tilt imaging system 2 , and the flight control system 3 .
[0052] In order to perform the flight mission of the fixed-wing UAV, further, such as figure 2 , image 3 , Figure 4 and Figure 5 As...
Embodiment 2
[0057] The present embodiment provides an oblique photographing method for the above-mentioned fixed-wing UAV, which is implemented according to the following steps: the stabilization control instruction includes an orbiting flight stabilization control instruction and a direct flight stabilization control instruction. When the fixed-wing UAV is When flying around according to the flying circle route, the lens stabilization module 332 sends a control command of the stabilization stabilization control to the attitude server group 23 of the stabilizer 22, and the attitude server group 23 drives the single lens 211 to adjust its attitude in real time for alignment. The circling center of the ring fly ring keeps the inclination angle of the single lens 211 constant. It should be noted that, since the single lens 211 is connected with the camera 21 as a whole, adjusting the tilt angle of the single lens 211 is also adjusting the tilt angle of the camera 21, and adjusting the posture...
Embodiment 3
[0065] This embodiment provides an oblique photography method for the above-mentioned fixed-wing UAV, which is implemented according to the following steps: when the fixed-wing UAV performs an orbiting flight according to the circumnavigation route, the lens stabilization module 332 sends out an orbiting increase The stability control command is sent to the attitude servo group 23 of the stabilizer 22, and the attitude servo group 23 drives the single lens 211 to adjust its attitude in real time to align with the circle center of the ring fly ring and keep the inclination angle of the single lens 211 constant. When the fixed-wing UAV flies horizontally according to the straight route, the lens stabilization module 332 sends a direct flight stabilization control command to the attitude server group 23, and the attitude server group 23 drives the single lens 211 to tilt the single lens 211. The angle is constant.
[0066] The difference between the third embodiment and the secon...
