Description
Technical Field

Background
Due to the fact that the naked eye 3D display technology does not need a user to wear 3D glasses for watching, user experience is greatly improved, and problems still need to be solved when a plurality of people watch the same display screen at the same time. According to the naked eye 3D display principle, different viewers see different positions in front of the naked eye 3D display panel, and the images seen by the left eye and the right eye are different from each other. When a plurality of people watch naked eye 3D content at the same time, the two eyes of some people are easily in wrong visual areas, so that the left eye can watch the left viewpoint content and the right viewpoint content (the right eye is the same), double images can appear in vision, and the experience is poor. Or, the left eye sees the right viewpoint content and the right eye sees the left viewpoint content, the convex portion is concave instead, and the stereoscopic vision is completely wrong.

Detailed Description
For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
Example 1
The naked eye 3D display method is applied to the intelligent terminal, the display screen of the intelligent terminal is covered with the electronic 3D optical film, and the electronic 3D optical film can be integrated on the display screen in the production process of the intelligent terminal or can be pasted on the display screen after the intelligent terminal is generated. The electronic 3D optical film in this embodiment can adjust the grating constant; alternatively, the electronic 3D optical film may be an electronic lenticular optical film, an electronic barrier parallax barrier optical film, or the like, and the structures of the electronic lenticular optical film and the electronic barrier parallax barrier optical film may refer to the prior art, which is not described in detail in this embodiment. The intelligent terminal carries out layout processing on the 3D content according to a preset algorithm, the 3D content is displayed on a display screen after being processed, light rays of a display image penetrate through an electronic 3D optical film to enter eyes of a user, left eye content of the user is seen by the left eye, right eye content of the user is seen by the right eye of the user, the left eye and the right eye see the image to generate a 3D stereoscopic impression in the brain of the user, and the user can see a 3D stereoscopic image. Alternatively, the smart terminal includes, but is not limited to, a smart phone, a computer, a smart television, a vehicle-mounted terminal, an advertisement player, a game player, and the like, that is, a terminal having a function of playing video. The 3D content includes 3D pictures, 3D videos, 3D games, and the like.
Referring to fig. 1, the naked eye 3D display method of the present embodiment includes the following steps:
and S1, the intelligent terminal performs initialization display on the display screen according to the preset unit layout length. In the embodiment, various modes are provided for performing initialization display on the display screen according to the preset unit arrangement length, for example, the initialization display can be performed on the display screen according to the preset unit arrangement length when the intelligent terminal is started; or when a 3D video player on the intelligent terminal is started, carrying out initialization display on a display screen according to the preset unit arrangement length; or when the 3D video player on the intelligent terminal loads the 3D content, the 3D content is initialized and displayed on the display screen according to the preset unit arrangement length.
And S2, acquiring the spatial position information of at least one group of human eyes in front of the display screen.
Specifically, when a plurality of users watch in front of the intelligent terminal, the intelligent terminal needs to acquire spatial position information of human eyes of all the users in front of the display screen. Alternatively, the intelligent terminal may position the human eyes through the wireless positioning module, the camera, and the like, in this embodiment, the camera is taken as an example to perform principle description, and other wireless positioning modules may be implemented by reference.
Referring to fig. 2, the camera and the display screen are located on the same side of the intelligent terminal, so that the camera can acquire images of all users in front of the display screen conveniently. The camera receives the image acquisition instruction and then acquires image information in front of the display screen, and after the image information is acquired, whether human eyes exist in the image information is identified through a human eye identification algorithm, and the human eye identification algorithm can refer to the prior art. After the identification, if the human eyes are not identified in the image information, the camera acquires the image information again and carries out human eye identification again. And if the human eyes are identified in the image information, acquiring spatial position information of at least one group of human eyes in the image information. It can be understood that the spatial position information of the human eyes in this embodiment is position information relative to the display screen, that is, a spatial coordinate system is established based on the display screen, and since the position of the camera is known, the spatial position information of each group of human eyes in the spatial coordinate system can be calculated according to the existing image algorithm. There are various ways to select the coordinate system, which is not limited in this embodiment.
When the spatial position information of the human eyes is calculated, considering that the user watches the video with the binocular central point as the base point, the embodiment first obtains the coordinates of the binocular central point of each group of human eyes according to all the spatial position information, that is, after a group of human eyes are identified by using an image identification technology, the coordinates of the binocular central point of the human eyes are calculated. For example, in fig. 2, there are 3 groups of human eyes in front of the display screen, the camera identifies the human eyes of the user after acquiring the user image in front of the display screen, and calculates spatial position information of each group of human eyes, and the binocular center point coordinates of the 3 groups of human eyes are calculated as follows: p1(x1, y1, z1), P2(x2, y2, z2), P3(x3, y3, z 3).
And S3, calculating the effective visual area width according to all the spatial position information.
Specifically, after determining the coordinates of the binocular central points of all the eyes in front of the display screen, the effective visual area width is calculated according to the coordinates of the binocular central points of all the eyes. In the calculation process, the coordinate of the binocular center point is taken as the center point of the width of the visual area, then the span of the left view and the right view is adjusted in equal quantity, and the width of the adjusted left view and the adjusted right view is within the range of 3.25 cm-6.5 cm. Referring to fig. 2, the coordinates of the binocular center points of 3 groups of human eyes are: p1(x1, y1, z1), P2(x2, y2, z2), and P3(x3, y3, z3), wherein the effective visual zone width is calculated according to the binocular center coordinates of 3 groups of human eyes, and L2 in fig. 2 is the effective visual zone width. Referring to fig. 3, P10 is the effective viewing zone before adjustment, and L1 is the effective viewing zone width of the effective viewing zone before adjustment; p20 is the effective viewing zone adjusted using this embodiment, and L2 is the effective viewing zone width of the adjusted effective viewing zone. It can be seen that, the width of the effective viewing area after adjustment is obviously smaller than that of the effective viewing area before adjustment, by reducing the width of the effective viewing area, more users can be accommodated in the effective viewing area range of the same size to watch, and each user can be ensured to clearly see the 3D stereoscopic image without reducing the resolution.
And S4, obtaining a target grating constant of the electronic 3D optical film according to the effective visual area width.
Specifically, in this embodiment, the preset unit layout length is fixed and unchanged, the distance between the display screen and the electronic 3D optical film is a known amount, and after the effective viewing area width is calculated, the target grating constant of the electronic 3D optical film is obtained according to the effective viewing area width, the distance between the display screen and the electronic 3D optical film, and the preset unit layout length.
Referring to fig. 3, P10 is an effective viewing area before adjustment, L1 is an effective viewing area width of the effective viewing area before adjustment, X is a grating constant of the electronic 3D optical film before adjustment, and a is a predetermined unit layout length, i.e., a unit of content layout length; p20 is the adjusted effective viewing zone using the present embodiment, L2 is the effective viewing zone width of the adjusted effective viewing zone, and Y is the grating constant of the adjusted electronic 3D optical film. It can be seen that the width of the effective viewing area after adjustment is significantly smaller than the width of the effective viewing area before adjustment in this embodiment, and the grating constant Y of the electronic 3D optical film after adjustment is smaller than the grating constant X of the electronic 3D optical film before adjustment. By reducing the width of the effective visual area, more users can watch the images within the effective visual area range with the same size, each user can clearly see the 3D stereoscopic image, the resolution ratio cannot be reduced, and the film watching experience of the users is improved.
And S5, adjusting the grating constant of the electronic 3D optical film to a target grating constant.
Specifically, in this embodiment, the intelligent terminal is connected to the electronic 3D optical film, for example, the intelligent terminal is connected to the electronic 3D optical film through a USB interface, and the intelligent terminal controls a grating constant of the electronic 3D optical film by adjusting an output voltage and/or an output current. It can be understood that after the electronic 3D optical film is selected, the corresponding relationship between the grating constant of the electronic 3D optical film and the working parameter, for example, the corresponding relationship between the grating constant of the electronic 3D optical film and the working voltage, can be known, and the required grating constant can be obtained by adjusting the working parameter. Therefore, after the target grating constant of the electronic 3D optical film is obtained through calculation, the intelligent terminal adjusts the grating constant of the electronic 3D optical film to the target grating constant according to the corresponding relation between the grating constant of the electronic 3D optical film and the working parameter.
Alternatively, after the target grating constant of the electronic 3D optical film is calculated, whether the target grating constant is the same as the current grating constant of the electronic 3D optical film or whether the target grating constant is within an allowable error range of the current grating constant of the electronic 3D optical film is determined. And if the target grating constant is the same as the current grating constant or the target grating constant is within the allowable error range of the current grating constant, the grating constant of the electronic 3D optical film is not adjusted. And if the target grating constant is different from the current grating constant or the target grating constant is not within the allowable error range of the current grating constant, adjusting the current grating constant of the electronic 3D optical film to the target grating constant.
Referring to fig. 4 and 5, fig. 4 is an effective viewing zone and an effective viewing zone width obtained using the prior art, where the effective viewing zone width L3 is 13cm and is a fixed value; when a plurality of people watch naked eye 3D content at the same time, the two eyes of some people are easily in wrong visual areas, so that the left eye can watch the left viewpoint content and the right viewpoint content (the right eye is the same), double images can appear in vision, and the experience is poor. Or, the left eye sees the right viewpoint content and the right eye sees the left viewpoint content, the convex portion is concave instead, and the stereoscopic vision is completely wrong. Fig. 5 shows the effective visual area and the effective visual area width obtained in this embodiment, and it can be seen that the effective visual area width after adjustment in this embodiment is significantly smaller than the effective visual area width before adjustment, and the value range of the effective visual area width after adjustment is 6.5cm to 13cm, where the value range of the effective visual area width is obtained from the statistical data of the eyes of the user; in addition, the grating constant Y of the adjusted electronic 3D optical film is smaller than the grating constant X of the electronic 3D optical film before adjustment. Through reducing the grating constant of electron 3D optical film, let the effective visual area scope of the same size accommodate more users and watch, and guarantee that every user can clearly see 3D stereoscopic image, can not reduce resolution ratio, improve the user and see shadow experience.
In the actual film watching process, the user is constantly changing, for example, the number of people watching the film is increased or decreased, the positions of human eyes are changed, and the like, so that the grating constant of the electronic 3D optical film needs to be dynamically adjusted to quickly adapt to the change of the user, and the film watching experience of the user is improved. Optionally, the intelligent terminal obtains the spatial position information of at least one group of human eyes in front of the display screen in real time, that is, the intelligent terminal continuously and circularly executes the steps S2 to S5 in real time, thereby realizing continuous and uninterrupted adjustment. Alternatively, the smart terminal may perform the steps S2 to S5 once at a preset time interval during the playing of the 3D content, where the preset time interval may be set by the user, for example, 10 seconds, 20 seconds, 30 seconds, and the like. Or, the user can manually issue an adjustment instruction, that is, the user adjusts the 3D stereoscopic image when the user thinks the image is not clear; the user may issue an adjustment command through a physical key, a virtual key, or voice, and the intelligent terminal receives the adjustment command for adjusting the grating constant of the electronic 3D optical film and then performs steps S2 to S5.
The embodiment does not need multi-view shooting to increase the number of the 3D contents, and adjusts the grating constant of the electronic 3D optical film by acquiring the spatial position information of a plurality of groups of human eyes, so that a plurality of people can watch the electronic 3D optical film simultaneously, the resolution ratio cannot be reduced, and the cost is low and the effect is good.
Example 2
Referring to fig. 6, on the basis of embodiment 1, in the naked eye 3D display method of the present embodiment, after step S2 and before step S3, the method further includes:
and S21, judging whether all human eyes are in the preset visual area corresponding to the preset unit arrangement diagram length according to the spatial position information. Since the preset unit arrangement length is fixed in this embodiment, the distance between the display screen and the electronic 3D optical film is a known quantity, and on this basis, the grating constant of the electronic 3D optical film is obtained according to the effective viewing area width, the preset unit arrangement length, and the distance between the display screen and the electronic 3D optical film. And after the preset visual area corresponding to the preset unit arrangement length is obtained, judging whether all human eyes are in the preset visual area corresponding to the preset unit arrangement length according to the spatial position information.
And S22, if all the human eyes are in the preset visual area corresponding to the preset unit layout length, and the current visual area meets all the user requirements, playing the 3D content according to the preset unit layout length without adjusting the grating constant of the electronic 3D optical film. If not all the human eyes are within the preset viewing area corresponding to the preset unit layout length, which indicates that the grating constant of the electronic 3D optical film needs to be adjusted, step S3 is executed.
The intelligent terminal performs initial display on the display screen according to the preset unit layout length, and adjusts the grating constant of the electronic 3D optical film when the visual area needs to be adjusted. In addition, the embodiment does not need multi-view shooting to increase the number of the 3D contents, and the grating constant of the electronic 3D optical film is adjusted by acquiring the spatial position information of a plurality of groups of human eyes, so that the simultaneous watching of a plurality of people can be realized, the resolution cannot be reduced, and the cost is low and the effect is good.

and S23, judging whether the requirement for watching all human eyes simultaneously can be met by adjusting the moving layout of the display screen according to the spatial position information, namely judging whether all human eyes can be positioned in the range of the effective visual area by adjusting the moving layout of the display screen according to the spatial position information, wherein the moving layout comprises left and right displacement of the layout and/or up and down displacement of the layout, namely, the adjustment can be completed only by the left and right displacement of the layout, or the adjustment can be completed only by the up and down displacement of the layout, or the adjustment can be completed by the left and right displacement of the layout and the up and down displacement of the layout at the same time, and the judging process can refer to the prior art.
And S24, if the requirement of watching by all human eyes simultaneously can be met by adjusting the moving layout of the display screen, adjusting the moving layout of the display screen according to the spatial position information, namely firstly calculating the moving layout according to the spatial position information, wherein the moving layout comprises the left and right displacement of the layout and/or the up and down displacement of the layout, and then arranging the display screen according to the moving layout. When the moving image arrangement amount is calculated according to the spatial position information, the position information of the left eye and the right eye of each group of human eyes is firstly obtained according to the spatial position information, and then the moving image arrangement amount is calculated according to the position information of the left eye and the right eye of all groups of human eyes. Referring to fig. 9, there are 3 groups of human eyes: the image displacement amount can be calculated according to the position information of the left eye and the right eye of the 3 groups of human eyes after the position information of the left eye and the right eye of the 3 groups of human eyes is acquired by using the P1L and the P1R as the group of human eyes, the P2L and the P2R as the group of human eyes and the P3L and the P3R as the group of human eyes. If the requirement for simultaneous viewing by all human eyes cannot be met by adjusting the movement layout of the display screen, step S3 is executed.
According to the embodiment, after the spatial position information is acquired, whether the requirement of watching all human eyes simultaneously can be met by adjusting the mobile layout of the display screen is judged, if yes, a subsequent adjusting scheme is not required to be executed, the adjustment can be completed quickly, and the resource consumption is low.
