However, from the statistical characteristics of image and depth information and the visual characteristics of human eyes, this processing method may not be optimal. First, the neighborhood correlation of depth information is obviously stronger than that of image information. The resolution of depth information is significantly lower than that of image information, therefore, depth information can be described with less data, and there is almost no change in 3D visual effect

Embodiment 1
[0032] The image and depth 3D image format is a 3D image format suitable for multi-viewpoint / super-multi-viewpoint naked-eye 3D display. Usually, the size of the image and depth information is the same, and the image resolution is only half of the resolution of the image format. For example, figure 1 shown; this is not expected by 3D image formats, because relative to image characteristics, the spatial correlation of depth information is stronger than that of image information and the depth resolution of human eyes is also lower than that of images, so more data can be used to Describing image information and using less data to describe depth information can significantly improve 3D image resolution, while the 3D depth perception effect is almost unchanged. According to the characteristics of naked-eye 3D display and the characteristics of the three primary colors of the display screen, it is a suitable choice to set the horizontal width ratio of image and depth information to ...

The invention discloses an image and depth 3D image format and a multi-viewpoint naked-eye 3D display method thereof. The method comprises the following steps of S1, horizontally amplifying a depth graph to equal with an image based on neighborhood correlation; S2, converting the depth graph to a parallax graph according to a preset parameter; S3, converting the parallax graph to a virtual viewpoint parallax graph according to a virtual viewpoint position; S4, generating a virtual viewpoint image based on virtual viewpoint parallax compensation; and S5, displaying a generated multi-viewpoint 3D image according to a multi-viewpoint naked-eye 3D display equipment parameter. According to the image and depth 3D image format provided by the invention, image information can be described through more data and depth information can be described through less data, thereby obtaining higher 3D image definition. Furthermore the invention provides the corresponding multi-viewpoint naked-eye 3D display method, wherein a vivid 3D display effect can be obtained.
Description
technical field [0001] The invention belongs to the technical field of 3D display and relates to a 3D image format, in particular to an image and depth 3D image format; at the same time, the invention also relates to a multi-viewpoint naked-eye 3D display method of the image and depth 3D image format. Background technique [0002] The image and depth 3D image format is a kind of 3D image format, which consists of an image and its corresponding depth information. Image and depth 3D image format is an intermediate format compared to 3D display. At present, there is no 3D display device that can directly display image and depth 3D image format. and the depth 3D image format are converted into a dual-viewpoint 3D format, such as the left and right format; if it is a naked-eye 3D display, the image and the depth 3D image format need to be converted into a multi-viewpoint 3D format, and the multi-viewpoint naked-eye 3D display in the present invention covers super multi-viewpoints...
