What is aerial photography?

Aerial photography, also known as aerial photography, aerial photography or aerial photography, refers to shooting the earth's landform from the air to get a top view, which is an aerial photograph. The aerial camera can be controlled by the photographer, and can also be automatically photographed or remotely controlled. The platforms used in aerial photography include airplanes, helicopters, hot air balloons, small spacecraft, rockets, kites and parachutes. In order to make aerial photos stable, advanced photographic equipment such as Spacecam is sometimes used, and the stable function of three-axis gyroscope can be used to provide high-quality stable images even under long focal length lenses.

Aerial flight control of unmanned aerial vehicle (UAV) for aerial photography is a high-tech product based on hardware, which integrates single chip microcomputer technology, aerial sensor technology, GPS navigation aerial photography technology, communication aerial photography service technology, flight control technology, task control technology and programming technology. Therefore, it is impossible to design a good flight control without any of the above technologies. The more flight experience and experience, the more ways to avoid problems in the initial design. It makes the flight test progress more smoothly. We should know that the debugging of flight control is mainly flight test. Unlike other automatic control products, flight test is high risk. Once the plane crashes and the hardware is damaged, it is difficult to analyze the cause of the accident, let alone solve the problem. This is also the reason why there are few mature and reliable flight controls.
