Embodiment Construction

[0032] A kind of new grating type multi-viewpoint stereo image synthesis method of the present invention comprises the following steps:

[0033] (1) Obtain the pitch parameters of the lenticular lens grating:

[0034] Lenticular grating pitch p: 1.407mm;

[0035] (2) Get the grating tilt angle parameters:

[0036] The inclination angle is , =2 / 9 (set counterclockwise rotation as a positive angle);

[0037] (3) Obtain sub-pixel and resolution parameters of stereoscopic display:

[0038] The sub-pixel size of the display is: 0.1805mm,

[0039] The resolution of the display is: 1920*1080 (the total number of sub-pixels is 1920*3*1080);

[0040] (4) Determine the number of viewpoints according to the pitch of the lenticular lens grating, the tilt angle of the grating and the size of the stereoscopic display sub-pixel:

[0041] ;

[0042] (5) Obtain the mapping relationship between sub-pixels and viewpoints, that is, determine the sub-pixel filling path...

Abstract

The invention discloses a grating-type multi-viewpoint stereo image synthesis method which comprises the following steps: (1) obtaining a lenticular grating pitch parameter p; (2) obtaining a grating inclination angle parameter; (3) obtaining a stereo display sub-pixel and a resolution parameter; (4) according to the size of the lenticular grating pitch, the grating inclination angle and the stereo display sub-pixel, determining the number of viewpoints; (5) obtaining the mapping relationship of the sub-pixel and the viewpoints, namely determining a sub-pixel filling path according to the stereo display grating inclination angle; and (6) after a sub-pixel mapping table is finished, successively filling the pixels of the multi-viewpoint image into a target stereo image according to the filling path. The grating-type multi-viewpoint stereo image synthesis method has the advantages that distortion-free stereo images can be obtained by virtue of the light splitting of a stereo display, and the stereo visual effect is good.

Description

technical field [0001] The invention belongs to the technical field of grating type autostereoscopic display imaging, and in particular relates to a grating type multi-viewpoint stereoscopic image synthesis method. 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-type autostereoscopic display device is made by adding a grating to ...
