The invention discloses a multi-view video super-resolution reconstruction algorithm based on improved virtual viewpoint synthesis, including the following steps: step (1), establishing a mapping relationship between a virtual viewpoint image and a reference viewpoint image with the aid of a depth image of reference viewpoints based on virtual viewpoint synthesis of DIBR; step (2) performing projection consistency check based on two-way DIBR; and step (3) performing high-frequency information extraction and super-resolution reconstruction to obtain a final super-resolution reconstruction result. Compared with the prior art, by adopting the scheme of the invention, small cracks can be effectively removed, and a pixel penetration phenomenon between the background and the foreground can be eliminated; and empty parts can be filled by extracting corresponding pixel points of interpolation images, a better viewpoint synthesis effect can be realized, and a good super-resolution reconstruction result can be obtained through the fusion of high-frequency extraction and interpolation views on this basis.
