Multi-scale imaging system field-of-view splicing calculation method based on concentric spherical lens

The invention relates to a multi-scale imaging system field-of-view splicing calculation method based on a concentric spherical lens. The method comprises the following steps: calculating the center field-of-view distance of adjacent detectors when the field-of-view overlaps of adjacent detectors; When the field of view of the optical system is overlapped, the minimum angle and the maximum angle of the adjacent micro-camera to the center of the spherical lens are calculated according to the distance of the field of view of the center of the adjacent detector. The size of the field-of-view overlap area of the optical system is adjusted according to the minimum and maximum angles of view. The method of the invention can control the size of the field of view overlap area according to the demand, and avoids the problems that the overlap area is too small in the field of view mosaic process, so that the image mosaic can not be realized, the overlap area is too large, the field of view is wasted, and the design dif
