The invention provides a static integrated imaging method and system based on a flat image. The method comprises the following steps: respectively determining the foreground, the medium shot and the background of the flat image; respectively copying and displacing the foreground, the medium shot and the background to obtain corresponding M*M array images, including: calculating the displacement amount of the foreground and the displacement amount of the background, and copying and displacing according to a preset line number M; combining the foreground, the medium shot and the background in the same visual angle to obtain M*M sub-image arrays; sampling and synthesizing the M*M sub-image arrays to obtain a unit image array; and printing the unit image array on a piece of printing paper through output equipment, and overlaying a three-dimensional display lens array or an orthogonal cylindrical lens grating, such that a three-dimensional image appears. The method disclosed by the invention has the advantages of being low in calculation amount, rapid, simple, convenient and the like and is applied to the field of anti-counterfeiting, such as anti-counterfeiting brands and anti-counterfeiting images; and furthermore, the method has relatively high-quality three-dimensional reappearing.
