The technical solution of the present invention is described in more detail by the following specific examples, and the present invention includes, but is not limited to, the following examples.
As shown in fig. 1, which is a schematic structural diagram of a naked-eye 3D display device provided in an embodiment of the present invention, the naked-eye 3D display device mainly includes: the display screen 11, in addition, includes: a grating panel 12 arranged on the light-emitting side of the display screen 11, a control device 13 for detachably fixing the grating panel 12 on the display screen 11, and a viewpoint tracking device 14 connected with the control device 13; wherein,
the viewpoint tracking device 14 is configured to obtain, in real time, position information of a current viewpoint of the viewer in front of the display screen 11 in the 3D display mode, and determine whether a position of the viewpoint of the viewer in front of the display screen 11 changes;
and a control device 13, configured to, when it is determined that the position of the viewpoint of the viewer in front of the display screen 11 changes, adjust the position of the raster panel 12 relative to the display screen 11 according to the position information of the current viewpoint of the viewer in front of the display screen 11, so that the current viewer views a 3D image picture through the raster panel 12.
As shown in fig. 2, a physical structure diagram of a naked eye 3D display proposed based on the naked eye 3D display device shown in fig. 1 is shown, wherein the naked eye 3D display sequentially includes, from a light incident direction to an emergent direction: a display screen 21, a raster panel 22, a control device 23 for detachably fixing the raster panel, and a viewpoint tracking device 24, wherein the viewpoint tracking device 24 may be integrated on the surface of the display screen 21, as shown in fig. 2, or integrated inside the display screen 21 (not shown). Preferably, the viewpoint tracking device 24 may be an infrared range finder or a human eye recognition device.
In the embodiment of the present invention, the grating panel 22 may only include the grating film layer 221 as shown in fig. 3(a), and preferably, considering that the grating panel 22 needs to be fixed in front of the display screen, the stability of the grating panel 22 is necessarily ensured, therefore, as shown in fig. 3(b), the grating panel 22 may further include: a grating film layer 221 and a transparent film layer 222 for carrying the grating film layer 221.
Wherein, evenly laid a plurality of light transmission stripes in the grating rete 221, wherein, the realization mode of grating rete 221 is comparatively nimble: a plurality of light-transmitting gaps may be formed on the non-transparent film layer, or a plurality of non-transparent stripes may be attached to the transparent film layer.
Considering that the pixels of each view under the naked eye 3D image have a certain arrangement rule, for example: as shown in fig. 4, a view pixel on the display screen 21 provided by the present invention is a partial example of a five-point view, and a grating direction in the grating film layer 221 located in front of the view pixel has a certain inclination angle, specifically, in an embodiment of the present invention, an extending direction of the light-transmitting stripe in the grating film layer 221 forms an angle of 13 ° to 17 ° with a vertical direction of the grating film layer 221. Preferably, the effect of an included angle of 15 ° is the best, so that the opening region is ensured to display only one view pixel as much as possible, crosstalk is reduced, and the 3D viewing effect is improved.
In addition, in the embodiment of the present invention, as shown in fig. 5, the control device is a mechanical component having a data processing function, for example: for the fixing frame 31 to be permanently fixed to the display screen, fixing bolts 32 are provided at four frame positions of the fixing frame 31 to be extendable and movable, and the fixing bolts 32 are moved in the respective adjusting directions by small electromechanical controls, so that the raster panel 22 fixed to the fixing bolts 32 is moved therewith.
Furthermore, the naked-eye 3D display device according to the above may view not only 3D image pictures but also 2D image pictures, and specifically, when a viewer wishes to view 2D image pictures, the above may be implemented in two ways:
the first method is as follows: the raster panel 22 fixed to the display screen 21 is removed, and only the display screen 21, the control device 23, and the viewpoint tracking device 24 are left, and at this time, the control device 23 and the viewpoint tracking device 24 do not substantially perform any processing without affecting the display of the 2D image.
The second method comprises the following steps: the raster panel 22 is not detached, and only needs to be adjusted to an area not covering the display screen 21 by the control device 23, and the control device 23 and the viewpoint tracking device 24 are the same, so that the reservation processing can be performed.
Therefore, under the condition of not increasing the cost, the grating panel is detached, installed or adjusted according to the watching desire of a watcher, and the function of watching a 3D image picture or a 2D image picture is flexibly realized.
Based on the same inventive concept, the embodiment of the invention also provides a method for realizing naked eye 3D display by using the naked eye 3D display device, which is described in detail by specific examples below.
As shown in fig. 6, a flowchart of a naked eye 3D display method provided in an embodiment of the present invention is mainly provided, where the method mainly includes the following steps:
step 41: under a naked eye 3D display mode, the viewpoint tracking device acquires the position information of the current viewpoint of the viewer in front of the display screen in real time and determines whether the position of the viewpoint of the viewer in front of the display screen changes.
Step 42: when the viewpoint tracking device determines that the position of the viewpoint of the viewer in front of the display screen changes, the control device adjusts the position information of the grating panel relative to the display screen according to the position information of the current viewpoint of the viewer in front of the display screen, so that the current viewer views the 3D image picture through the grating panel.
As can be seen from the foregoing preferred solutions, in the embodiment of the present invention, the viewpoint position information of the current viewer is obtained in real time by the viewpoint tracking device, and if it is determined that the position of the viewpoint of the viewer in front of the display screen changes, the viewpoint position information of the current viewer is sent to the control device, the control device performs calculation according to an algorithm stored in the control device, and then adjusts the position of the grating panel relative to the display screen according to the settlement result, so that the viewer views a better 3D display picture, thereby improving the effect of viewing the 3D image picture and the viewing experience.
As a preferred solution of the embodiment of the present invention, step 42 may be specifically executed as:
the first step is as follows: and the control device determines ideal position information of the grating panel according to the position information of the current viewpoint of the viewer in front of the display screen.
The second step is that: and adjusting the position of the grating panel relative to the display screen according to the determined ideal position information of the grating panel.
In fact, the specific execution operation of step 42 is flexible, and the position adjustment information required to be adjusted by the current raster panel can be directly calculated according to the corresponding algorithm and directly adjusted to the ideal position of the raster panel.
Preferably, the first step is specifically performed as:
establishing a coordinate system in a first extending direction perpendicular to the plane of the display screen and a second extending direction parallel to the plane of the display panel;
determining coordinate information of a first extending direction in ideal position information of the lenticular panel based on coordinate information of the first extending direction in position information of a current viewpoint of a viewer in front of the display screen, and,
and determining the coordinate information of the second extending direction in the ideal position information of the grating panel according to the coordinate information of the second extending direction in the position information of the current viewpoint of the viewer in front of the display screen.
Preferably, the second step is specifically performed as:
and adjusting the distance between the grating panel and the display screen and/or adjusting the left and right positions of the grating panel on the current plane relative to the display screen according to the determined ideal position information of the grating panel.
The above technical solution is explained below by specific examples.
Specifically, as shown in fig. 7(a) -7 (b), for a set of raster panel adjustment diagrams provided by the embodiment of the present invention, as shown in fig. 7(a), if it is determined that the position of the viewpoint of the viewer moves from the original position 1 to the position 2, the position 2 is not the position of the view focus of the raster panel 22, and therefore, the viewed 3D image frame may have crosstalk. To avoid this, the position of the raster panel 22 relative to the display screen 21 can be adjusted.
For the sake of clarity and brief description of the following specific adjustment scheme, a coordinate system may be established in advance, and considering that the position of the display screen 21 is fixed, the coordinate system is established in a first extending direction Y perpendicular to the plane of the display screen 21 and a second extending direction X parallel to the plane of the display screen, where the position of the viewpoint of the viewer is denoted as X-X1 and Y-D.
As is clear from fig. 7(a), since the direction of change of the position of the viewpoint of the viewer is indefinite, the direction may change only in the X direction, only in the Y direction, or both in the X direction and the Y direction. Therefore, the specific adjustment of the control device can be sequentially adjusted or adjusted simultaneously according to the setting. The present invention is not limited thereto.
Assuming that the position of the viewpoint of the viewer changes in both the X direction and the Y direction, it is necessary to separately determine coordinate information in the X direction in the ideal position information of the raster panel 22 and coordinate information in the Y direction in the ideal position information of the raster panel 22. The order of the determination of the two variables is not limited.
One is as follows: the Y-direction coordinate information in the ideal position information of the raster panel 22 is determined according to the Y-direction coordinate information in the position information of the viewer's current viewpoint in front of the display screen, which can be specifically determined by the following formula (1):
wherein, f is the space between adjacent light-transmitting stripes in the grating film layer; the n is the number of pixels of each unit view in the display screen; the p is the width of a view pixel; d is coordinate information of a first extending direction (i.e., Y direction) in the position information of the current viewpoint of the viewer in front of the display screen; the d is coordinate information of a first extending direction (i.e., Y direction) in the ideal position information of the grating panel.
The second step is as follows: the determining, according to the coordinate information in the X direction in the position information of the current viewpoint of the viewer in front of the display screen, the coordinate information in the X direction in the ideal position information of the raster panel 22 specifically includes:
selecting an information correspondence table matched with the coordinate information of the first extending direction (namely, the X direction) in the determined ideal position information of the raster panel 22 from a preset information correspondence table set, wherein the information correspondence table records a plurality of groups of correspondence relationships between the coordinate information of the second extending direction (namely, the X direction) in the position information of the current viewpoint of the viewer in front of the display screen and the coordinate information of the second extending direction (namely, the X direction) in the ideal position information of the corresponding raster panel; searching the information corresponding table according to the coordinate information of the second extending direction in the position information of the current viewpoint of the viewer in front of the display screen; and determining the coordinate information of the second extending direction in the ideal position information of the grating panel corresponding to the coordinate information of the second extending direction in the position information of the current viewpoint of the viewer in front of the display screen.
By the scheme, the X-direction coordinate information and the Y-direction coordinate information in the ideal position information of the grating panel can be respectively determined, and then the control device can adjust the left and right positions of the grating panel on the current plane relative to the display screen according to the X-direction coordinate information and adjust the distance between the grating panel and the display screen according to the Y-direction coordinate information. The adjusted schematic diagram is shown with reference to fig. 7(b), wherein the dashed box indicates the adjusted position of the raster panel.
It should be noted that, in the above-mentioned solution, the adjustment is mainly performed for one viewer, or only one main viewer among a plurality of viewers (located in the same plane in front of the raster panel), and the adjusted viewing effect generally serves only one viewer. However, in the embodiment of the present invention, in consideration of the situation that a plurality of viewers need to be considered, when the left and right positions of the raster panel in the current plane relative to the display screen are adjusted according to the coordinate information of the X direction in the position information of the current viewpoint of the viewer in front of the display screen, the left and right positions may be determined according to the following formula (2):
wherein, s is the adjustment displacement of the grating panel; the n is the number of pixels of each unit view in the display screen; xi is X-direction coordinate information of the viewpoint position of the viewer corresponding to the maximum position interval, and D isxiThe maximum position separation between the individual viewers.
Through this formula (2) to statistical theory's analysis, adjust the grating panel to the ideal position that the maximum viewer can effectively watch the 3D image picture, thereby, promoted this bore hole 3D display device's practicality.
While preferred embodiments of the present invention have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. Therefore, it is intended that the appended claims be interpreted as including preferred embodiments and all such alterations and modifications as fall within the scope of the invention.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention.
