For example, shooting can be started by indicating that the printed page enters the shooting range through the control information, shooting is continued for a plurality of times, a plurality of images containing the page to be archived are obtained, and the plurality of images can be spliced into a complete page to be archived. The preset time is the time from the paper conveying equipment to the shooting range of the shooting equipment for the page to be archived.
Step S106, recognizing a photographed image by adopting an image recognition algorithm, and cutting to obtain an orthographic image of a target page in the photographed image; the orthographic image obtained through cutting can not only improve the preservation quality of the archived page, but also facilitate the subsequent reference.
