Now more and more people use drones to take aerial photos of weddings. Looking down from the air, they can take attractive wedding photos. They can film the motorcade that picks up the bride, the crowds that take the bride home, and the scenes that relatives and friends celebrate with salutes and belts. However, it is recommended not to use drones indoors, because the lack of GPS signals indoors will lead to inaccurate positioning, rapid decline in handling performance and easy accidents. At present, DJI UAV is the most widely used one in wedding aerial photography.
