Problems solved by technology

[0003] The viewing angle of the photographing equipment in the prior art is limited, that is, the range covered by the lens of the photographing equipment is limited, resulting in a limited scene area in the photos taken by the photographing equipment. In order to take photos with a wider viewing angle, you can Install a fisheye lens on the shooting equipment, a fisheye lens is a lens with an angle of view close to or equal to 180°
Because the scenery seen by the human eye in real life is regular or has a fixed shape, and there is a big difference between the fisheye lens and the real world scene in the human eye, the picture effect produced by the fisheye lens exceeds the human vision The normal range of the fisheye lens causes distortion in the photos
[0004] Therefore, there is a lack of a method for shooting ultra-wide-angle, high-quality photos in the prior art

Abstract

A wide-angle photo shooting method, device, platform (20, 70, 1004), unmanned aerial vehicle and robot. The method for obtaining wide-angle photos includes: controlling the lens (22, 1005, 2005) to take pictures at multiple azimuths, the multiple azimuths include n latitude information and m longitude information, n is an integer greater than or equal to 2, and m is greater than Or an integer equal to 1; the photos taken by the lens (22, 1005, 2005) at multiple azimuth angles are synthesized into a super wide-angle photo. By controlling the lens (22, 1005, 2005) to take pictures in multiple azimuths, and combining the photos taken by the lens (22, 1005, 2005) in each azimuth into a super wide-angle photo, the shooting of super wide-angle photos is realized , there will be no distortion problems such as fisheye lenses, and the quality of ultra-wide-angle photos will be improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of unmanned aerial vehicles, and in particular to a wide-angle photo shooting method, device, platform, unmanned aerial vehicle and robot. Background technique [0002] Shooting equipment has become an increasingly common device. Users use shooting equipment, such as cameras on mobile phones and digital cameras, to take pictures of their interest. In addition, shooting equipment can also be used in the field of drones. Shooting equipment for aerial photography. [0003] The viewing angle of the photographing equipment in the prior art is limited, that is, the range covered by the lens of the photographing equipment is limited, resulting in a limited scene area in the photos taken by the photographing equipment. In order to take photos with a wider viewing angle, you can Install a fisheye lens on the shooting device, which is a lens with a viewing angle close to or equal to 180°. Because the sce...
