Embodiment Construction

[0035] The object of the present invention is to propose a depth perception enhancement method for virtual multi-viewpoint rendering based on the principle of human visual depth perception. Depth-based virtual viewpoint rendering technology is currently the most widely used 3D generation technology. However, due to the reduction of disparity between adjacent viewpoints drawn, the depth difference between objects will be reduced, resulting in a weakened sense of depth for stereoscopic display. Aiming at this problem, the present invention realizes a depth perception enhancement method for multi-virtual viewpoint rendering by adjusting the disparity map, and achieves the purpose of improving the stereoscopic display effect.

[0036] When the virtual multi-viewpoint rendering based on the depth image is used for autostereoscopic display, the parallax between adjacent viewpoints will be greatly reduced, resulting in poor depth perception of the observed stereoscopic image. In ord...

Abstract

The invention belongs to the field of three-dimensional image processing, and provides a depth perception enhancing method for virtual multi-view drawing according to a human eye visual depth perception principle; the depth perception enhancing method for virtual multi-view drawing is realized by adjusting a disparity map; and thus, the purpose of improving the stereo display effect is achieved. The technical scheme provided by the invention is as follows: the depth perception enhancing method for virtual multi-view drawing comprises the following steps: (1), segmenting an image; (2), deducing a just-noticeable depth difference model for virtual multi-view drawing; (3), performing depth perception enhancing for virtual multi-view drawing; (4), drawing multiple virtual views; and (5), performing auto-stereoscopic displaying. The depth perception enhancing method for virtual multi-view drawing disclosed by the invention is mainly applied to image processing.

Description

technical field [0001] The invention belongs to the field of stereoscopic image processing, and relates to a depth perception enhancement method for virtual multi-viewpoint rendering to enhance the stereoscopic effect of stereoscopic display. technical background [0002] Stereoscopic (3D) technology is a general term for various technologies that use the principle of binocular stereoscopic vision and combine various depth or parallax clues to enable viewers to obtain a three-dimensional sense from display devices. 3D display technology can be divided into traditional stereoscopic display technology and naked-eye stereoscopic display technology. Traditional stereoscopic display technology needs to wear glasses to observe the stereoscopic effect of 3D images. The naked-eye stereoscopic display technology does not need to wear glasses, and the stereoscopic effect of 3D images can be observed with naked eyes. Free stereoscopic display technology is one of the main development...
