as shown in fig. 3, the naked eye 3D display based on the reconstructed light field according to the embodiment of the present invention includes the following steps:
and step S100, acquiring three-dimensional image information to be displayed and position information of each pixel of the naked eye 3D display device.
Specifically, the three-dimensional image information generated according to the acquisition device or the virtual engine. The three-dimensional image information includes original pixel information and original position information of each pixel point, and since the original position information of each pixel point is not on one plane, light rays emitted from the three-dimensional spaces represent a 3D image.
Step S200, determining two-dimensional image information of each pixel of the naked eye 3D display device according to the position information of each pixel of the naked eye 3D display device and the three-dimensional image information, where the two-dimensional image information includes: and the direction information and the display pixel information corresponding to the direction information.
Specifically, the naked eye 3D display device may adopt a flat panel display or a curved surface display, and the two-dimensional image information of each pixel of the naked eye 3D display device is determined according to the position information and the three-dimensional image information of each pixel of the naked eye 3D display device, where the two-dimensional image information is relative to a stereoscopic image formed by the three-dimensional image information, and the arrangement mode of the two-dimensional image information is matched with the shape of the naked eye 3D display device, that is, when the naked eye 3D display device adopts the flat panel display, the two-dimensional image information arrangement may form a flat panel shape, and when the naked eye 3D display device adopts the curved surface display, the two-dimensional image information arrangement may form a curved surface shape.
The direction information refers to information of directions of light rays emitted by pixels of the naked eye 3D display device, and in order to enable the naked eye 3D display device to display three-dimensional images, directions of the light rays emitted by pixels of the naked eye 3D display device are different, and after receiving the light rays emitted by the pixels of the naked eye 3D display device, a brain can consider that the three-dimensional images are seen. Display pixel information refers to information of optical properties of light emitted by pixels of the naked eye 3D display device, for example, the display pixel information includes color information and intensity information. By displaying the pixel information, different images are formed, and objects to be displayed are displayed.
The step S200 specifically includes:
step S210, determining a target pixel corresponding to each pixel point of the three-dimensional image information according to the original position information of the pixel point; the target pixels are pixels in the naked eye 3D display device, and the number of the target pixels is larger than a preset threshold value and smaller than or equal to the total number of pixels in the naked eye 3D display device.
Specifically, in displaying a two-dimensional image, each pixel of the two-dimensional image information corresponds to a pixel of a display device or a pixel of a region through which light is emitted to display the two-dimensional image. In displaying a three-dimensional image, each pixel point of the three-dimensional image information corresponds to a part or all of target pixels of the naked eye 3D display device, and light rays are emitted through the part or all of target pixels to display the three-dimensional image.
For example, as shown in fig. 2, each pixel of the three-dimensional image information corresponds to a part or all of pixels in the naked eye 3D display device, each pixel of the three-dimensional image information is displayed by all of the pixels on the naked eye 3D display device, and the optical properties of the light rays emitted by all of the pixels are the same or similar (i.e. the display pixel information is the same or similar), but the directions are different, the pixels are observed by the left eye and the right eye respectively, and the human brain considers that the target pixels are the same pixels (the same pixels are virtual in nature) due to the fact that the optical properties of the light rays emitted by the target pixels are the same or similar, and the same pixels are located at a certain position behind the naked eye 3D display device, and the light rays are emitted from the position. Since the positions of the target pixels corresponding to each pixel point of the three-dimensional image information are different, the positions of the same pixel are different, and a three-dimensional image can be formed. For example, the closer the positions of the two target pixels corresponding to each pixel point of the three-dimensional image information are, the closer the same pixel is to the naked eye 3D display device, and the farther the positions of the two target pixels corresponding to each pixel point of the three-dimensional image information are, the farther the same pixel is from the naked eye 3D display device.
The number of target pixels is related to the viewing range of the three-dimensional image, and the more the target pixels, the three-dimensional image can be seen on a larger range in front of the naked-eye 3D display device, and the fewer the target pixels, the three-dimensional image can be seen on a smaller range in front of the naked-eye 3D display device. The preset threshold value may be set as required, for example, all pixels of the naked eye 3D display device may be used as target pixels, and the viewing range of the three-dimensional image may be expanded as much as possible.
Step S220, determining the direction information of each target pixel according to the original position information of the pixel point and the position information of each target pixel.
Specifically, according to the original position information of the pixel point of the three-dimensional image information and the position information of the target pixel, determining the direction information of the target pixel, wherein the larger the distance between the projection of the original position information of the pixel point of the three-dimensional image information on the naked eye 3D display device and the position information of the target pixel is, the smaller the included angle between the direction of the target pixel and the naked eye 3D display device is, and the smaller the distance between the projection of the original position information of the pixel point of the three-dimensional image information on the naked eye 3D display device and the position information of the target pixel is, the larger the included angle between the direction of the target pixel and the naked eye 3D display device is. The included angle between the direction of the target pixel and the naked eye 3D display device is 0-90 degrees.
Step S230, taking the original pixel information of the pixel point as display pixel information corresponding to the direction information of each target pixel; wherein the original pixel information includes color information and intensity information.
Specifically, for a certain pixel point of the three-dimensional image information, the direction information of each target pixel corresponding to the pixel point is different, but the display pixel information of each target pixel is the same as the original pixel information of the pixel point of the three-dimensional image information, that is, when different audiences watch the target pixel point from different positions, the brain considers the light rays emitted by the same pixel, and the optical properties of the light rays emitted by the same pixel are the same.
Step S240, obtaining two-dimensional image information of each pixel according to the direction information and the display pixel information of each pixel.
Specifically, a pixel in the naked eye 3D display device may be used as a target pixel corresponding to a plurality of pixel points of the three-dimensional image information, when the pixel in the naked eye 3D display device is used as a target pixel of different pixel points of the three-dimensional image information, the direction information of the pixel is different, the larger the projected distance between two different pixel points of the three-dimensional image information on the naked eye 3D display device is, the larger the difference between two direction information of the pixel is, and the smaller the projected distance between two different pixel points of the three-dimensional image information on the naked eye 3D display device is, the smaller the difference between two direction information of the pixel is. And displaying pixel information corresponding to each piece of direction information of the pixels in the naked eye 3D display device, and forming two-dimensional image information corresponding to the pixels according to all pieces of direction information of the pixels and the display pixel information corresponding to each piece of direction information.
And step S300, controlling the light emitting devices of the pixels to emit light for display according to the two-dimensional image information of the pixels of the naked eye 3D display device.
Specifically, two-dimensional image information of each pixel of the naked eye 3D display device is obtained, and light rays emitted by the light emitting devices of each pixel of the naked eye 3D display device are controlled to display. Specifically, a target light emitting device corresponding to the direction information is determined according to the direction information of each pixel of the naked eye 3D display device, then display pixel information corresponding to the light emitting device is determined according to the display pixel information of each direction information corresponding to the light emitting device, and then the light emitting device is controlled to emit light for display according to the display pixel information corresponding to the light emitting device.
The step S300 specifically includes:
step S310, determining target light emitting devices corresponding to the direction information of each pixel of the naked eye 3D display device; the target light emitting device is one of a plurality of light emitting devices in the pixel.
Specifically, there may be 0, 1 or more directional information of the pixels of the naked eye 3D display device, and each directional information has a corresponding target light emitting device, and typically only one target light emitting device is present in each directional information.
The connecting line direction of the light emitting device and the center of the lens is the light emitting direction of the light emitting device, namely, the connecting line direction of the center line of each light emitting device and the lens is used as the light emitting direction of the light emitting device, the number of the light emitting devices in the pixel is the same as the number of the light emitting directions of the light emitting devices in the pixel, the target light emitting device is the light emitting device with the smallest included angle between the light emitting direction and the direction of the direction information, and the light emitting direction with the smallest included angle between the light emitting device and the direction of the direction information is determined from the light emitting directions in the pixel, so that the light emitting device is used as the target light emitting device.

The step S320 specifically includes:
step S321, for all direction information corresponding to the light emitting device, obtaining display pixel information corresponding to the light emitting device according to the display pixel information corresponding to all direction information.
Specifically, for one pixel of the naked eye 3D display device, the direction information may be different, the corresponding light emitting device may not have the corresponding direction information (the light emitting device is controlled to emit no light) or 1 direction information (the display pixel information corresponding to the direction information is used as the display pixel information corresponding to the light emitting device), or a plurality of direction information (the display pixel information corresponding to the light emitting device is obtained according to the display pixel information respectively corresponding to the plurality of direction information) may be present.
Specifically, for all the direction information corresponding to the light emitting device, the average value mode may be adopted to calculate the display pixel information corresponding to all the direction information, so as to obtain the display pixel information corresponding to the light emitting device. For example, the color information includes R (red) value, G (green) value, and B (blue) value, and the R values corresponding to all the direction information are averaged, and the obtained average value is used as the R value in the display pixel information corresponding to the light emitting device. And (3) averaging the G values corresponding to all the direction information, wherein the obtained average value is used as the G value in the display pixel information corresponding to the light emitting device.
