Spliced imaging system based on axis-shifting principle

The invention discloses a spliced imaging system based on an axis-shifting principle, comprising at least one imaging lens and at least one imaging device, wherein the imaging lens is arranged on the same plane and has same focal length and view field; the imaging device is arranged on the focal plane of each imaging lens; each imaging lens is set into a mode that the optical axis of the imaging lens is vertical to the focal plane thereof; and each imaging device is set into a mode that the focal plane of the imaging device has preset axis-shifting amount. The system disclosed by the invention overcomes the defects in the traditional multiple-camera imaging technology that later-stage image processing has high complexity under the condition of inclined imaging, and precise simultaneous exposure cannot be realized under the condition of vertical imaging. In addition, the spliced imaging system expands the imaging range under the vertical installation condition of the cameras.
