Embodiment Construction

[0027] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to make a clearer and clearer definition of the protection scope of the present invention.

[0028] See figure 1 , The embodiment of the present invention includes:

[0029] A virtual viewpoint synthesis method based on layered processing, the specific steps are:

[0030] 1) Preprocessing of depth correction and color correction of the depth map of the left and right view points respectively.

[0031] 1.1) Perform depth correction preprocessing on the depth maps of the left and right viewpoints respectively.

[0032] For edge depth error correction, morphological processing methods such as image expansion and erosion are used to correct the wrong depth information on the edge of the object.

[0033] For the background depth error...

Abstract

The invention discloses a virtual viewpoint synthesizing method based on layered processing. Firstly preprocessing of depth correction and color correction is performed on depth maps of left and right viewpoints; then the image of a virtual viewpoint is generated by adopting layered 3D Warping; color images and depth images of left and right reference viewpoints generated by DIBR are integrated according to layered information, and then filtering processing is performed on the integrated depth maps; then the image of the virtual viewpoint is corrected according to the depth maps, and holes in the image are eliminated; and finally image interpolation and post processing are performed, a ghost phenomenon in the image is removed and finally a high-quality new viewpoint is generated. An intermediate viewpoint can be rapidly synthesized according to any two viewpoints, and picture quality of the newly synthesized viewpoint is relatively high.

Description

Technical field [0001] The invention belongs to the field of virtual point image synthesis in a stereoscopic display system, and particularly relates to a layered virtual viewpoint image synthesis method in a stereoscopic display system. Background technique [0002] As high-definition display technology and imaging technology continue to mature, people's requirements for multi-view stereo viewing will become more urgent. This makes television technology face a new technological change from 2D video to 3D video conversion. Three-Dimensional Television (3DTV), with its immersive effect of reproducing three-dimensional scenes, will give people a new viewing experience. , Is another brand new development direction in the TV field after HDTV. As an important branch of stereo TV, Free Viewpoint Television (FTV) can not only meet the needs of multi-users for scene depth perception by displaying multiple stereo image pairs at the same time, without any auxiliary visual equipment. It c...
