Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
In order to better understand the present invention, a brief description is first made of a naked-eye 3D display terminal according to an embodiment of the present invention. The naked eye 3D display terminal comprises a display, and different from a conventional display, the display of the naked eye 3D display terminal comprises a display screen and a light splitting device arranged on the display screen. The Display screen is used to Display an image, and may be, for example, a conventional 2D Display panel, such as an LCD (Liquid Crystal Display) panel, an OLED (organic light-Emitting Diode) panel, and the light splitting device is used to split the image displayed by the Display screen, and may be, for example, a grating, which may be any one of gratings that can be used in a naked-eye 3D Display terminal in the prior art, such as a slit grating or a lenticular grating, which is not limited in this invention. The naked eye 3D display terminal according to the embodiment of the present invention may be any image display terminal such as a display, a mobile phone, a tablet computer, a personal computer, and an all-in-one machine, which is not limited in this respect.
Referring to fig. 1, a display control method of a naked eye 3D display terminal according to an embodiment of the present invention includes:
step 101, determining the current screen display direction of the naked eye 3D display terminal.
In the embodiment of the invention, the naked eye 3D display terminal is compatible with horizontal screen 3D (stereoscopic) display and vertical screen (namely vertical screen) 3D display. Here, by determining the screen display direction of the naked-eye 3D display terminal, it is convenient to determine whether to perform landscape-screen 3D display or portrait-screen 3D display. As shown in fig. 2a and 2b, the screen display direction includes a landscape screen direction and a portrait screen direction. When the naked eye 3D display terminal performs 3D display, firstly, it needs to be judged how the user holds the display terminal to enable the display terminal to be in a landscape display or a portrait display, namely, the current screen display direction of the naked eye 3D display terminal is determined to be in a landscape direction or a portrait direction. If the naked eye 3D display terminal is used for vertical screen display, vertical screen 3D display is needed, and if the naked eye 3D display terminal is used for horizontal screen display, horizontal screen 3D display is needed. Specifically, whether the display terminal is in the landscape orientation or the portrait orientation may be determined according to a known gyroscope gesture detection technology, which will not be described herein again. Of course, it can be understood that, in the embodiment, the manner of determining the display direction of the terminal screen is not limited, and may be reasonably selected by a person skilled in the art.
For convenience of description, the screen display direction will be hereinafter referred to as a first direction and a second direction, the first direction being one of the landscape direction and the portrait direction, and the second direction being the other of the landscape direction and the portrait direction.
Step 102, when the current screen display direction of the naked eye 3D display terminal is a first direction, obtaining a first three-dimensional display parameter corresponding to the first direction.
In principle, when the naked eye 3D display terminal performs stereoscopic display, stereoscopic images need to be arranged and displayed on the display screen according to a certain rule, that is, the left-eye image and the right-eye image are subjected to image arrangement processing, that is, the left-eye image and the right-eye image are rearranged at a certain angle and period according to the optical characteristics of the light splitting device. After the images are arranged, the light splitting effect of the light splitting device is matched, so that the left eye image is sent to the left eye of a user, and the right eye image is sent to the right eye of the user, and the user can watch the three-dimensional image.
In the embodiment of the invention, the stereoscopic display parameters comprise layout parameters related to the specific distribution of the screen layout. The stereoscopic display parameter may specifically include at least one of a layout displacement, a layout inclination angle, and a layout period of the stereoscopic image on the screen. As shown in fig. 7, the dotted line represents a periodic arrangement of the stereoscopic images on the display screen, wherein the arrangement parameters include: the line map inclination angle c ', the line map period p' and the line map displacement delta ', wherein the line map displacement delta' is the horizontal distance between the line map central point and the intersection point closest to the line map central point in the intersection points of the line map and the horizontal coordinate axis X, and can also be called the horizontal distance between the line map initial point and the line map coordinate origin. For the mapping parameters, reference may be made to the prior art, which is not described in detail herein.
It can be understood that the arrangement is required to match the optical characteristics of the light-splitting device, and therefore, the optical characteristics are different when the light-splitting device is different, or the same light-splitting device is in different display directions, that is, the arrangement parameters are different, that is, different arrangement parameters are required for the horizontal-screen stereoscopic display and the vertical-screen stereoscopic display.
In this step, when the current screen display direction of the naked eye 3D display terminal is the first direction, a first stereoscopic display parameter corresponding to the first direction is acquired, so that stereoscopic display in the first direction is performed based on the first stereoscopic display parameter.
In the embodiment of the present invention, the first direction is one of a horizontal screen direction and a vertical screen direction, and the second direction is the other of the horizontal screen direction and the vertical screen direction. The first direction corresponds to a first stereoscopic display parameter, and the second direction corresponds to a second stereoscopic display parameter, that is, the first stereoscopic display parameter and the second stereoscopic display parameter may each include at least one of a layout displacement, a layout inclination angle, and a layout period of a stereoscopic image on a screen. And when the first direction is the transverse screen direction, acquiring the three-dimensional display parameters corresponding to the transverse screen direction so as to perform transverse screen three-dimensional display based on the acquired three-dimensional display parameters. And when the first direction is the longitudinal screen direction, acquiring the stereoscopic display parameters corresponding to the longitudinal screen direction so as to perform longitudinal screen stereoscopic display based on the acquired stereoscopic display parameters.

When the screen display direction of the naked eye 3D display terminal is detected to be changed, in the process that the screen display direction of the naked eye 3D display terminal is changed from a first direction (a transverse screen direction) to a second direction (a longitudinal screen direction), when the rotation angle is smaller than 45 degrees, the stereoscopic display in the transverse screen direction is kept according to the first stereoscopic display parameter and the aspect ratio of 16:9, when the rotation angle is larger than 45 degrees, the stereoscopic display in the longitudinal screen direction is carried out according to the third transitional stereoscopic display parameter and the aspect ratio of 4:3 until the screen display direction of the naked eye 3D display terminal is changed from the transverse screen direction to the longitudinal screen direction.
In the embodiment of the invention, in the transition process of changing the screen display direction of the naked eye 3D display terminal from the first direction to the second direction, two switching modes of completing horizontal and vertical screen switching in the 2D display mode and completing horizontal and vertical screen switching in the 3D display mode are supported.

The naked eye 3D terminal in the embodiment of the invention supports tracking display, wherein the tracking display refers to tracking the watching position of a user (namely a display content viewer) in real time, displaying according to the watching position of the user, so that the display content watched by the user is matched with the watching position of the user, and adaptively adjusting the display content watched by the user when the watching position of the user changes.
Here, by determining the first spatial viewing position of the user, the first-direction stereoscopic display is facilitated based on the first spatial viewing position of the user, thereby realizing the tracking display.
It should be noted that, how to determine the first spatial viewing position of the user is not limited in the embodiments of the present invention, and a person skilled in the art may reasonably select and may determine the first spatial viewing position of the user in any known manner.
Specifically, optionally, the face recognition may be performed on the user to obtain the facial feature position information of the user, and then the first spatial viewing position of the user is determined according to the facial feature position information of the user. Or detecting an infrared emitter arranged on the body of the user, acquiring spatial position information of the infrared emitter, and then determining the first spatial viewing position of the user according to the spatial position information of the infrared emitter.

and 1032, performing first-direction stereoscopic display according to the first stereoscopic display parameter and the first space viewing position.
And after the watching position of the user is changed, the user can still watch a correct stereoscopic display effect, and the problem of poor experience of the user such as dizziness caused by reverse vision, ghost images, distortion and the like is avoided.
The new stereoscopic display parameters can be determined according to the first stereoscopic display parameters and the first space viewing position, and stereoscopic display is performed according to the new stereoscopic display parameters, that is, the arrangement mode of the display content on the display screen is adjusted, for example, the positions of the pixel points are changed, that is, the original pixel points are moved to the new positions, and the like, so that the purpose of adjusting the display content is achieved.
It is to be understood that the new stereoscopic display parameters may be determined according to the determined first spatial viewing position and the first stereoscopic display parameters in any known manner, which is not limited by the present invention, referring to the prior art. For example, a corresponding functional relationship between the viewing position and the stereoscopic display parameter is set in advance, and after the viewing position is determined, the viewing position is substituted into the functional relationship, thereby determining the stereoscopic display parameter.
When the screen display direction of the naked eye 3D display terminal is changed from the first direction to the second direction, the method further comprises the following steps:
at step 1018, a second spatial viewing position of the user is determined.
As described above, the naked-eye 3D terminal in the embodiment of the present invention supports tracking display, and here, by determining the second spatial viewing position of the user, it is convenient to perform second-direction stereoscopic display based on the second spatial viewing position of the user, so as to implement tracking display.
It should be noted that, how to determine the second spatial viewing position of the user is not limited in the embodiment of the present invention, and a person skilled in the art may reasonably select and may determine the second spatial viewing position of the user in any known manner. Reference may be made to the above-mentioned manner for determining the first spatial viewing position of the user, and details are not repeated here.
The step 106 includes:
step 1062, performing stereoscopic display in the second direction according to the second stereoscopic display parameter and the second spatial viewing position.
And the second-direction stereoscopic display is carried out by combining the second stereoscopic display parameter and the second space viewing position, so that the tracking display is realized, the user can still view the correct stereoscopic display effect after the viewing position of the user is changed, and the problem of poor experience of the user such as dizziness caused by reverse vision, ghost images, distortion and the like is avoided.
Specifically, the process of performing stereoscopic display in the second direction according to the second stereoscopic display parameter and the second spatial viewing position may refer to the above-mentioned process of performing stereoscopic display in the first direction according to the first stereoscopic display parameter and the first spatial viewing position, and details are not repeated here.
In the embodiment of the invention, the tracking display is realized when the first-direction stereo display is carried out and the first-direction stereo display is changed into the second-direction stereo display, so that the user can still watch the correct stereo display effect after the watching position of the user is changed, and the problem of poor experience of the user such as dizziness and the like caused by reverse vision, ghost images, distortion and the like is avoided.
In the embodiment of the invention, when the screen display direction of the naked eye 3D display terminal is detected to be changed, and in the process of changing the screen display direction of the naked eye 3D display terminal from the first direction to the second direction, when the horizontal and vertical screen switching is completed in the 3D display mode, the tracking display can be realized by referring to the above method, which is not described herein again.
In the embodiment of the invention, when the first stereoscopic display parameter is known, the second stereoscopic display parameter can be obtained by utilizing the corresponding relation between the first stereoscopic display parameter and the second stereoscopic display parameter. Or when the second stereoscopic display parameter is known, the first stereoscopic display parameter can be obtained by utilizing the corresponding relation between the second stereoscopic display parameter and the first stereoscopic display parameter. The first case is described in detail below as an example.
In an embodiment of the present invention, the stereoscopic display parameter includes a layout inclination (a raster inclination), and in a case of raster sharing, that is, in a case that the stereoscopic display in the first direction and the stereoscopic display in the second direction use the same light splitting device, that is, in a case that switching of the light splitting device is not required when performing horizontal and vertical screen switching, in this case, the layout inclination of the first stereoscopic display parameter and the layout inclination of the second stereoscopic display parameter may include the following corresponding relationship:
cotα*cotβ＝-1；
wherein α is the inclination angle of the layout of the first stereoscopic display parameter, and β is the inclination angle of the layout of the second stereoscopic display parameter.
The first direction stereo display can be horizontal screen direction stereo display or vertical screen direction stereo display, and when the first direction stereo display is horizontal screen direction stereo display, the second direction stereo display is vertical screen direction stereo display; correspondingly, when the first-direction stereoscopic display is the vertical-screen-direction stereoscopic display, the second-direction stereoscopic display is the horizontal-screen-direction stereoscopic display.
In principle, the coordinate systems corresponding to the first-direction stereoscopic display and the second-direction stereoscopic display have a difference of 90 degrees, and since the coordinate systems corresponding to the first-direction stereoscopic display and the second-direction stereoscopic display have a difference of 90 degrees, the row diagram inclination angle α of the corresponding first stereoscopic display parameter and the row diagram inclination angle β of the corresponding second stereoscopic display parameter have a difference of 90 degrees, it can be determined that the corresponding relationship between the row diagram inclination angle of the first stereoscopic display parameter and the row diagram inclination angle of the second stereoscopic display parameter is: cot α × cot β ═ 1.
After the arrangement inclination angle alpha of the first stereo display parameter is obtained, the cotangent value of the arrangement inclination angle beta is calculated according to the corresponding relation between the arrangement inclination angle alpha of the first stereo display parameter and the arrangement inclination angle of the second stereo display parameter, and therefore the arrangement inclination angle of the second stereo display parameter is obtained.
Taking the first-direction stereoscopic display as the horizontal-screen-direction stereoscopic display and the second-direction stereoscopic display as the vertical-screen-direction stereoscopic display as an example, as shown in fig. 3a and 3b, under the horizontal-screen-direction stereoscopic display, the arrangement inclination angle of the first stereoscopic display parameter is α, where α is the angle between the raster image and the horizontal direction. In the case of a portrait orientation stereoscopic display, the inclination angle of the line map of the second stereoscopic display parameter is β, where β differs from α by 90 degrees, i.e., β ═ pi/2 + α. Then, the trigonometric function relationship cot (pi/2 + α) — tan α may result in cot β ═ 1/cot α, that is, the relationship between the swath tilt angle of the first stereoscopic display parameter and the swath tilt angle of the second stereoscopic display parameter is: cot α × cot β ═ 1.
After the corresponding relationship between the inclination angle α and the inclination angle β is obtained, the inclination angle β of the bar chart may be determined according to the inclination angle α of the bar chart.
In one embodiment of the invention, the stereoscopic display parameters include a period of the raster pattern, which may be determined according to the horizontal pitch of the grating. In the case of grating sharing, that is, when the first-direction stereoscopic display and the second-direction stereoscopic display use the same light splitting device, that is, when the horizontal-vertical screen switching is performed, the switching of the light splitting device is not required, in this case, when the first-direction stereoscopic display is the horizontal-screen-direction stereoscopic display, and the second-direction stereoscopic display is the vertical-screen-direction stereoscopic display, the grating horizontal pitch of the first stereoscopic display parameter and the grating horizontal pitch of the second stereoscopic display parameter may include the following correspondence:
t1＝t0/cotα；
wherein t0 is the grating horizontal pitch of the horizontal screen direction stereo display, t1 is the grating horizontal pitch of the vertical screen direction stereo display, and α is the row diagram inclination angle of the horizontal screen direction stereo display.
It is understood that the above correspondence relationship can also be expressed as a correspondence relationship between the horizontal grating pitch and the inclination angle of the raster pattern of the first stereoscopic display parameter and the horizontal grating pitch of the raster pattern of the second stereoscopic display parameter.
For the case that the stereoscopic display in the first direction is the stereoscopic display in the horizontal screen direction, and the stereoscopic display in the second direction is the stereoscopic display in the vertical screen direction, after obtaining the grating horizontal pitch t0 of the stereoscopic display in the horizontal screen direction, it is necessary to determine the corresponding relationship between the grating horizontal pitch t0 of the stereoscopic display in the horizontal screen direction and the grating horizontal pitch t1 of the stereoscopic display in the vertical screen direction. In principle, as shown in fig. 3a, when t is the pitch in the landscape stereoscopic display, the relationship between t0 and t is t0 sin α. As shown in fig. 3b, in the vertical stereoscopic display, t is the pitch, t1 is the horizontal pitch of the grating in the vertical stereoscopic display mode, and at this time, the relationship between t and t1 is t1 cos α, then t1 cos α is t0 sin α, and after dividing both sides of the equation by sin α, the equation can be obtained to obtain t1 cot α is t0, so that the relationship between t1 t0/cot α can be obtained, that is, the correspondence between the horizontal pitch t0 of the grating in the horizontal stereoscopic display and the horizontal pitch t1 of the grating in the vertical stereoscopic display can be obtained.
After the corresponding relationship between the raster horizontal pitch t0 and the raster horizontal pitch t1 is obtained, the raster horizontal pitch t1 of the vertical screen direction stereoscopic display can be determined according to the obtained raster horizontal pitch t0 of the horizontal screen direction stereoscopic display and the corresponding relationship.
The method specifically comprises the following steps: after obtaining the grating horizontal grid distance t0 of the stereoscopic display in the transverse screen direction, calculating the cotangent value cot alpha of the grating inclination angle alpha of the stereoscopic display in the transverse screen direction, and then calculating the ratio of the grating horizontal grid distance t0 to the cotangent value cot alpha, so as to obtain the grating horizontal grid distance t1 of the stereoscopic display in the longitudinal screen direction.
Specifically, for example, in the case of raster sharing, that is, in the case where the same beam splitter is used for the first-direction stereoscopic display and the second-direction stereoscopic display, that is, in the case where the horizontal-vertical screen switching is performed, the switching of the beam splitter is not required, in this case, when the first-direction stereoscopic display is the vertical-screen-direction stereoscopic display and the second-direction stereoscopic display is the horizontal-screen-direction stereoscopic display, the raster horizontal pitch of the first stereoscopic display parameter and the raster horizontal pitch of the second stereoscopic display parameter may include the following corresponding relationship:
t0＝t1/cotβ；
wherein t0 is the grating horizontal grid pitch of the horizontal screen direction stereo display, t1 is the grating horizontal grid pitch of the vertical screen direction stereo display, and β is the row diagram inclination angle of the vertical screen direction stereo display.
It is understood that the above correspondence relationship can also be expressed as a correspondence relationship between the horizontal grating pitch and the inclination angle of the raster pattern of the first stereoscopic display parameter and the horizontal grating pitch of the raster pattern of the second stereoscopic display parameter.
For the case that the stereoscopic display in the first direction is the stereoscopic display in the vertical screen direction, and the stereoscopic display in the second direction is the stereoscopic display in the horizontal screen direction, after obtaining the grating horizontal pitch t1 of the stereoscopic display in the vertical screen direction, it is necessary to determine the corresponding relationship between the grating horizontal pitch t1 of the stereoscopic display in the vertical screen direction and the grating horizontal pitch t0 of the stereoscopic display in the horizontal screen direction. In principle, as shown in fig. 4a, when t is a pitch in the stereoscopic display in the vertical direction, the relationship between t1 and t is t1 sin β. As shown in fig. 4b, in the case of the lateral stereoscopic display, t is the pitch, t0 is the grating horizontal pitch of the lateral stereoscopic display mode, and at this time, the relationship between t and t0 is t0 cos β, the following relationship t1 sin β is t0 cos β, and the processing of dividing the two sides of the equation by sin β simultaneously can obtain t1 t0 cos β, so that the relationship between t0 t1/cot β can be obtained, that is, the corresponding relationship between the grating horizontal pitch t1 of the vertical stereoscopic display and the grating horizontal pitch t0 of the lateral stereoscopic display.
After the corresponding relationship between the grating horizontal pitch t1 of the vertical screen direction stereoscopic display and the grating horizontal pitch t0 of the horizontal screen direction stereoscopic display is obtained, the grating horizontal pitch t0 of the horizontal screen direction stereoscopic display can be obtained according to the grating horizontal pitch t1 of the vertical screen direction stereoscopic display and the corresponding relationship.
The method specifically comprises the following steps: after obtaining the grating horizontal grid distance t1 of the vertical screen direction stereo display, calculating the cotangent value cot beta of the arrangement diagram inclination angle beta of the vertical screen direction stereo display, and then calculating the ratio of the grating horizontal grid distance t1 to the cotangent value cot beta, namely obtaining the grating horizontal grid distance t0 of the horizontal screen direction stereo display.
In an embodiment of the present invention, the stereoscopic display parameters include a layout shift (raster shift), and in a case where the same beam splitter is used for raster sharing, that is, the stereoscopic display in the first direction and the stereoscopic display in the second direction, that is, the switching of the beam splitter is not required when the horizontal and vertical screens are switched, in this case, when the stereoscopic display in the first direction is the stereoscopic display in the horizontal screen direction, and the stereoscopic display in the second direction is the stereoscopic display in the vertical screen direction, the layout shift of the first stereoscopic display parameters and the layout shift of the second stereoscopic display parameters may include the following correspondence:
Δ1＝Δ0/cotα；
wherein Δ 0 is the arrangement displacement of the three-dimensional display in the horizontal screen direction, Δ 1 is the arrangement displacement of the three-dimensional display in the vertical screen direction, and α is the arrangement inclination angle of the three-dimensional display in the horizontal screen direction.
It is understood that the above correspondence relationship can also be expressed as a correspondence relationship between the layout displacement of the first stereoscopic display parameter, the layout inclination angle, and the layout displacement of the second stereoscopic display parameter. The derivation process of the corresponding relationship between the arrangement displacement of the first stereoscopic display parameter and the arrangement displacement of the second stereoscopic display parameter is similar to the derivation process of the corresponding relationship between the grating horizontal pitch of the first stereoscopic display parameter and the grating horizontal pitch of the second stereoscopic display parameter, and is not repeated here.
After obtaining the arrangement displacement delta 0 of the three-dimensional display in the transverse screen direction, calculating the cotangent value cot alpha of the grating inclination angle alpha of the three-dimensional display in the transverse screen direction, and then calculating the ratio of the arrangement displacement delta 0 to the cotangent value cot alpha, namely obtaining the arrangement displacement delta 1 of the three-dimensional display in the longitudinal screen direction.
Specifically, for example, in the case of raster sharing, that is, in the case where the same beam splitter is used for the first-direction stereoscopic display and the second-direction stereoscopic display, that is, in the case where switching of the beam splitter is not required when switching between horizontal and vertical screens is performed, when the first-direction stereoscopic display is the vertical-screen stereoscopic display and the second-direction stereoscopic display is the horizontal-screen stereoscopic display, the arrangement displacement of the first stereoscopic display parameter and the arrangement displacement of the second stereoscopic display parameter include the following correspondence relationship:
Δ0＝Δ1/cotβ；
wherein Δ 0 is the arrangement displacement of the horizontal screen direction stereoscopic display, Δ 1 is the arrangement displacement of the vertical screen direction stereoscopic display, and β is the arrangement inclination angle of the vertical screen direction stereoscopic display.
It is understood that the above correspondence relationship can also be expressed as a correspondence relationship between the layout displacement of the first stereoscopic display parameter, the layout inclination angle, and the layout displacement of the second stereoscopic display parameter.
After obtaining the arrangement diagram displacement delta 1 of the vertical screen direction stereo display, calculating the cotangent value cot beta of the arrangement diagram inclination angle beta of the vertical screen direction stereo display, and then calculating the ratio of the arrangement diagram displacement delta 1 to the cotangent value cot beta, namely obtaining the arrangement diagram displacement delta 0 of the horizontal screen direction stereo display.
Thus, the second stereoscopic display parameter is obtained according to the first stereoscopic display parameter and the corresponding relationship between the first stereoscopic display parameter and the second stereoscopic display parameter.
In a specific application process, under the condition that a screen display direction needs to be determined, when the screen display direction is a first direction, the naked eye 3D display terminal needs to call a first stereo display parameter stored in advance to perform naked eye stereo display, when the screen display direction is changed from the first direction to a second direction, the naked eye 3D display terminal needs to call a second stereo display parameter stored in advance to perform naked eye stereo display, or the second stereo display parameter is calculated by using the first stereo display parameter stored in advance and a corresponding relation, and then the second stereo display parameter is used to perform naked eye stereo display.
It should be understood that the above correspondence relationships are only examples, and those skilled in the art can reasonably select the correspondence relationships based on the design concept provided by the embodiments of the present invention.
In the embodiment of the present invention, the parameter of the horizontal screen direction stereoscopic display may be used as a reference, or the parameter of the vertical screen direction stereoscopic display may be used as a reference, when the parameter of the horizontal screen direction stereoscopic display is used as a reference, the first stereoscopic display parameter needs to be determined according to the related information of the horizontal screen direction stereoscopic display, and when the parameter of the vertical screen direction stereoscopic display is used as a reference, the first stereoscopic display parameter needs to be determined according to the related information of the vertical screen direction stereoscopic display. The difference between the related information under the horizontal screen direction stereo display and the related information under the vertical screen direction stereo display is as follows: the optical characteristics of the screen change and the spatial coordinates also differ.
Through the above process, when the first stereoscopic display parameter is known, the second stereoscopic display parameter is obtained by using the corresponding relationship between the first stereoscopic display parameter and the second stereoscopic display parameter.
In the embodiment of the present invention, the process of obtaining the second stereoscopic display parameter by using the corresponding relationship between the first stereoscopic display parameter and the second stereoscopic display parameter may be referred to, and when the second stereoscopic display parameter is known, the first stereoscopic display parameter is obtained by using the corresponding relationship between the second stereoscopic display parameter and the first stereoscopic display parameter.
