Abstract

The invention provides a wide angle photograph shooting method, apparatus, holder, unmanned aerial vehicle and robot. The method for obtaining wide angle photographs comprises the following steps: controlling a lens to shoot in multiple azimuth angles, wherein the multiple azimuth angles comprise n latitude information and m longitude information, n is an integer which is more than or equal to 2, and m is an integer which is more than or equal to 1; photographs shot in multiple azimuth angles shot by the lens is synthesized into the wide angle photograph. The lens is controlled for shooting in azimuth angles, the photographs shot by the lens in multiple azimuth angles are synthesized into an ultra-wide photograph, in order to realize shooting of ultra-wide photographs without distortion problems of fish-eye lens, and improve quality of the ultra-wide photograph.

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...
