Abstract:
Display method and system for converting 2D image into multi-viewpoint image is disclosed, comprising: acquiring and tagging a target object within a 2D image; calculating a depth value according to a frequency component; generating a layered image before viewing from different preset viewpoints; tagging a viewpoint image; estimating before filling a pixel in a blank area of a virtual viewpoint image, based on a depth value difference of the layered image, generating and saving sequentially a single-viewpoint image output, before detecting and filling a blank area in it; detecting before smoothing a sudden change area; assembling to form a synthesized image, processing and sending to a naked-eye 3D display screen for displaying. It converts a 2D image to a multi-viewpoint image, provides a naked-eye 3D display, reduces image distortion, easy and convenient to use, with a low cost.

Claim (Index 3):
The display method according to  claim 2 , wherein viewing the plurality of layered images from a plurality of different preset viewpoint positions, and tagging a viewpoint image, then adopting different interpolation algorithms to estimate a pixel in a blank area of a virtual viewpoint image on a basis of a difference between the depth values of the layered images before filling the blank area, removing a space between two layers of the layered images and forming a virtual viewpoint image, scaling the viewpoint image before generating a single-viewpoint image for output, comprising specifically:\n viewing the layered images through the different preset viewpoint positions, and tagging respectively a position of an actual viewpoint and a position of the virtual viewpoint in the viewpoint images; acquiring the depth values of the target objects where the tagged virtual viewpoint locates, and based on the difference between the depth values of the target objects, adopting different interpolation algorithms to perform an interpolation calculation according to the difference of the depth values of the target object, obtaining before filling the pixels of each position of the blank area in the tagged virtual viewpoint according to a calculated result, and removing the space between two layers in the layered image, before forming the virtual viewpoint images; scaling both an actual viewpoint image and the virtual viewpoint image respectively to a preset scale before generating and outputting a single-viewpoint image accordingly.
