Abstract

The invention discloses a synthetic method of a grating stereo-display sub-pixel-level stereo image, which comprises the following steps: (1) acquiring a multi-viewpoint image with horizontal parallax; (2) dividing a stereo display into areas of which the number is equal to that of viewpoints by row and column according to the number of the viewpoints of the multi-viewpoint image, and then marking the number for the areas; (3) dividing a target stereo image into target blocks of which the number is consistent with that of viewpoint image resolution; (4) determining a sub-pixel filling path according to the grating inclined angle of the stereo display; and (5) sequentially filling sub-pixels of the multi-viewpoint image to the target stereo image according to the filling path to complete the mapping from the multi-width viewpoint image to the stereo image. The sub-pixel position of each viewpoint image of the generated stereo image corresponds to the sub-pixel position of the stereo image, and the stereo image which is not distorted can be obtained by the light split of the grating of the stereo display and has an excellent stereo visual effect.

Description

technical field [0001] The invention belongs to the technical field of grating type free stereoscopic display imaging, in particular to a sub-pixel level stereoscopic image synthesis method of grating type stereoscopic display. technical background [0002] Autostereoscopic display technology has attracted the attention of many researchers in recent years because it can enable observers to see images with stereoscopic display effects without wearing stereoscopic glasses. At present, various stereoscopic display products have been developed, including flat panel masking, stripe grating, prism mirror and holographic display, etc. Compared with other autostereoscopic display technologies, grating-type stereoscopic display has the advantages of easy product processing and good stereoscopic effect, and has developed rapidly, becoming the main development direction of autostereoscopic display technology. [0003] The grating autostereoscopic display device is made by adding a gra...
