[0002] With the rapid development of drone technology, drone photography has been widely used in various fields, such as photography creation, film and television shooting, geographic surveying and mapping, and news reporting.

[0003] However, in actual use, the camera functions of traditional drones are relatively simple. In complex lighting environments, such as low light or strong light reflection scenes, the quality of the photos taken is difficult to be satisfactory.

[0036] Working principle: Camera installation and angle adjustment: The photographing camera 130 is placed inside the installation frame 211, and the lens penetrates through the through hole of the abutting plate 212. The limiting rail 216 and the limiting plate 217 fix the position of the photographing camera 130 through the positioning bolt 218 to prevent its displacement. The servos 215 at the top of the upper connecting frame 214 and at both ends of the positioning frame 213 work. The upper connecting frame 214 can drive the positioning frame 213 to rotate relative to the UAV body 110 through the servos 215, and the positioning frame 213 drives the installation frame 211 to rotate through the servos 215, so as to realize the flexible adjustment of the photographing camera 130 at multiple angles.

[0037] Installation and adjustment of auxiliary equipment: Place auxiliary photographing equipment such as a fill light bar or a filter in the limiting frame 226, and rotate the transmission screw rod 2271. The transmission screw rod 2271 drives the pressing plate 227 to slide in the limiting frame 226, so as to clamp and fix the auxiliary equipment. By rotating the side connecting shaft 222 on the outside of the fixing block 221, the upper transmission rod 223 is driven to rotate. The upper transmission rod 223 drives the bottom connecting rod 225 to move through the lower transmission hinge rod 224, and further adjusts the position of the limiting frame 226, so that the auxiliary equipment is located at a suitable position directly in front of the photographing camera 130. The transmission block 228 on the back of the limiting frame 226 and the connecting frame 229 are connected through a damping rotating shaft, and the angle of the auxiliary equipment can be further finely adjusted to meet different shooting requirements.
