The present invention is applicable to the technical field of aerial photography. Disclosed are a panoramic photographing apparatus, a panoramic photographing system, a photographing method, and an aircraft. The photographing apparatus comprises a support connected to an aircraft body and a photographing module mounted on the support. The photographing module comprises a first photographing module and a second photographing module arranged in a first direction and a second direction. The first direction is opposite to the second direction. A line of sight corresponding to a maximum angle of view of the first photographing module intersects a line of sight corresponding to a maximum angle of view of the second photographing module. The photographing method uses the photographing apparatus. The aircraft comprises the photographing apparatus. The panoramic photographing system comprises the remote terminal and the photographing apparatus/aircraft. In the panoramic photographing apparatus, the panoramic photographing system, the photographing method, and the aircraft provided by the present invention, the aircraft body and the photographing apparatus are completely hidden during capturing of a panoramic photo or a panoramic video, thereby ensuring a good panoramic photographing effect, and facilitating subsequent image processing.

Provided in the present invention are a method for achieving a bullet time capturing effect and a panoramic camera. The method comprises: acquiring a panoramic video captured when a panoramic camera rotates around a capture target; acquiring from within the panoramic video hemispherical images close to the side of the capture target; splicing the hemispherical images to generate a spliced image; and fixing a viewpoint of the spliced image, thus achieving a bullet time capturing effect. According to the present invention, only one panoramic camera is needed to be able to capture the bullet time capturing effect, so that the capturing cost of the bullet time capturing effect in the present invention is low. Meanwhile, since the bullet time capturing effect is obtained by means of a panoramic video being captured when a panoramic camera rotates around a capture target and processing being carried out on the panoramic video, the precision is high.
