What is the relationship between 3D imaging and 360-degree panoramic shooting?

Panorama can be divided into cylindrical panorama and spherical panorama according to its external manifestations. Cylindrical panorama is the simplest panorama, commonly known as "looking around". In the cylindrical panorama, you can watch the surrounding scenery in a horizontal 360-degree circle, but if you drag it up and down with the mouse, the upper and lower horizons will be limited, and you can't see the zenith above and the underground below; The spherical panorama can reach the effect of 360 degrees horizontally, up and down 180 degrees. When observing the spherical panorama, the observer is located in the center of the ball, and can observe any angle through the operation of the mouse and keyboard, completely integrating into the virtual environment.

360-degree three-dimensional panorama of the scene:

Scene type 360 degrees (horizontal, pitching) The three-dimensional panorama of the root scene is the viewing angle of 360 degrees horizontally and 180 degrees vertically, that is, the full viewing angle of 360X 180. can

Say that you have integrated into the virtual environment. The production of spherical panoramic photos is more complicated. Stereoscopic panoramic photograph

It consists of six photos: front, back, left, right, top and bottom. The camera is located in the center of the cube and has a panoramic view.

At present, there are two shooting ways: the first way is to use a conventional film camera to shoot the subject in the form of film, as well as the front and back.

Behind, left, right, up, down, all the surrounding scenes were photographed. When displaying, the photos must be pieced together one by one to form a blank space.

The heart is spherical, the picture is inward, and then the viewer looks inside the ball. Secondly, it uses fisheye lens or conventional lens to shoot, and then uses special software to splice and synthesize. Images formed in this form can only be viewed and demonstrated by computers. These two shooting techniques are both called spherical panorama of inner sphere.

360-degree three-dimensional panorama of objects;

When shooting a 360-degree three-dimensional panorama of the object, do equidistant multi-dimensional rotation shooting around the shooting object until the whole sphere is shot.

During the exhibition, the pictures are spliced into a sphere one by one, and the pictures look out. This shooting technique is called outer spherical panorama.

The object panorama is aimed at e-commerce on the Internet, and its main difference from the landscape panorama is that the observer is outside the object.

Nearby. Panorama of objects also has a wide range of applications: goods and toys display, cultural relics viewing, art and crafts display and so on.

Panoramic overview

Whenever a plane image is mapped to a surface, image projection will occur, and vice versa, which is especially common in panoramic photography. For example, the spherical surface of the earth can be mapped onto a flat paper. Since the whole field of vision around us can be regarded as the surface of a sphere (for all viewing angles), we need a method that can project the sphere into a two-dimensional plane to print photos.
