Panoramic imaging system and control method thereof

The invention provides a panoramic imaging system and a control method thereof. The panoramic imaging system comprises a shell with a containing cavity and at least two imaging units arranged in the containing cavity, wherein the imaging units are rotationally connected with the shell; the imaging units are distributed; a main camera shooting opening communicating the containing cavity with the external space is formed in the side wall of the shell; in the containing cavity, the focal sections of the imaging units are gradually reduced in the direction from a position close to the main camera shooting opening to a position away from the main camera shooting opening, and the focal sections of the imaging units with the same or similar distance from the main camera shooting opening are the same or similar. According to the invention, not only can the consistency between the definition of the target located at the distance and the definition of the target located near in the imaging system be improved, but also
