Focusing multi-image-sensor multi-image-distance super-depth-of-field imaging system

The invention discloses a focus-adjustable multi-image-sensor multi-image-distance super-depth-of-field imaging system. Comprising an optical unit, an imaging and electromechanical control unit and a system shell, the optical unit adopts a single lens to be matched with a multi-path spectroscope, and light entering from the lens is averagely divided into multiple paths to be irradiated to the multiple image sensors respectively. The imaging and electromechanical control unit comprises an image sensor module and an embedded visual controller. The automatic image distance adjusting and focusing module can control the image sensor module to move back and forth, and the effect of changing the image focusing position is achieved by changing the image distance. The multi-image-distance image fusion module can fuse a plurality of images with different image distances to form an ultra-depth-of-field image. The above units are combined to finally achieve the purpose of simultaneously imaging multiple image distances t
