Detailed Description
For the purpose of promoting a better understanding of the objects, aspects and advantages of the present disclosure, reference is made to the following detailed description taken in conjunction with the accompanying drawings.
It is to be noted that technical terms or scientific terms used in the embodiments of the present disclosure should have a general meaning as understood by those having ordinary skill in the art to which the present disclosure belongs, unless otherwise defined. The use of "first," "second," and similar terms in the embodiments of the disclosure is not intended to indicate any order, quantity, or importance, but rather to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect.
The acquisition process of the position of the viewing user described in each of the embodiments described below is obtained on the premise that the viewing user confirms that the acquisition is permitted. During specific implementation, a popup window for 'whether to allow the position to be acquired' is popped up on the terminal equipment used by the watching user, the user clicks and confirms the popup window, the position of the watching user is acquired, or the position which can be allowed to be acquired is preset by the watching user through the terminal equipment, and then when the position of the watching user is acquired, a corresponding dialog box is not popped up.
In addition, the 3D image acquisition described in the following embodiments is also performed after the user of the display device authorizes the acquisition and transmission of the 3D image.
In the related art, as shown in fig. 1A, it is mainly composed of 2 3D display ports (a display screen a and a display screen B in fig. 1A) equipped with a light field camera array (a light field camera array a and a light field camera array B in fig. 1A), respectively. The user A can see the 3D image of the user B in front of the display screen A, the user B can see the 3D image of the user A in front of the display screen B, and the 3D image signals of the 2 users are respectively acquired in real time by the light field camera array equipped with the other display port.
The camera used for 3D image acquisition is an RGBD (Red Green Blue Depth) camera, and can acquire Depth information of an image. The method comprises the steps of collecting an image with depth information through an RGBD camera, carrying out 3D modeling on the shot image, transmitting the modeled 3D image model to another port, and displaying after arranging the image.
In this manner, when the user B wants to view the 3D image of the user a, as shown in fig. 1B, the position of the user B with respect to the user a is random and continuous, but the number of camera arrays is limited, and the position is discrete and fixed, so it is necessary to determine, according to the position of the user B, to capture an image using 2 cameras closest to the position in the apparatus a, and then perform viewpoint synthesis. As shown in fig. 1C, the position of the user B corresponds to the position of the dotted line camera of the device a, but the position has no physical camera, so the device B performs the viewpoint interpolation algorithm to synthesize the images captured by the camera n and the camera n +1 before displaying the images.
Problems with this are: the viewpoint interpolation image is synthesized by using a viewpoint interpolation algorithm, so the image quality is not good as that of the image directly shot at the position, and the viewpoint interpolation algorithm needs longer time and has poor real-time performance.
In view of the above problem, an embodiment of the present disclosure provides a display device 200, as shown in fig. 2A, which is configured with a display area and a light field acquisition area, where the display device 200 includes:
a display panel 210, including a display structure 210a disposed in the display region and a light selection structure 210b disposed in the light field collection region, configured to determine a light transmission region (a pixel opening region as shown in fig. 2C) of the light selection structure 210b according to a position of a viewing user, and control the light transmission region to be in a light transmission state: a backlight module 220 disposed at a backlight side of the display structure 210 a; a camera array 230 disposed on the backlight side of the light selecting structure 210b and configured to activate at least one camera corresponding to the light transmissive region for 3D image acquisition.
In specific implementation, when 3D image acquisition is not performed, the light field acquisition region is in an opaque dark state, and a user can view corresponding picture playing contents through the display region. When 3D image acquisition is needed, a watching user can obtain a request of a 3D image through terminal equipment, and the request can carry the position of the watching user. Thus, the display device 200 can open the light-transmitting region corresponding to the position of the viewing user in the light selecting structure 210b according to the position of the viewing user, so that light can be transmitted through the light-transmitting region; and controls at least one camera corresponding to the light-transmitting area in the camera array 230 to start 3D image acquisition, to obtain 3D image information, and sends the 3D image information to the terminal device of the viewing user, so that the viewing user can view the 3D image. If the position of the viewing user moves, the display device 200 adjusts the corresponding light-transmitting area and the activated camera in real time.
Wherein the light field collecting section may be disposed at an upper portion or a lower portion of the display device 200, and a specific disposition position is not particularly limited herein (as shown in fig. 2B, the light field collecting region is disposed at an upper portion of the display device 200). The terminal device of the viewing user is a terminal device capable of 3D image display.
Through the scheme, the part for acquiring the light field can share the same display panel 210 with the display part, so that the use is more convenient, and the integral structure is more attractive. When carrying out the light field and gathering, can be according to watching corresponding printing opacity region of user's position determination, let this printing opacity region be in the printing opacity state to open the camera that this printing opacity region corresponds, make image light can be through printing opacity regional transmission to the camera on, and then carry out 3D image acquisition through the camera, then send the 3D image of gathering to watching the user side and show. Can adjust the printing opacity region like this according to watching user's position, the camera that sets up on display device 200 can be with watching user's visual angle collection corresponding 3D image, need not algorithm synthesis, when guaranteeing 3D image quality, can reduce the time delay time, has guaranteed the real-time of 3D image transmission.
In some embodiments, the Display panel 210 is an LCD (Liquid Crystal Display) panel. As shown in fig. 2A, the display panel 210 includes:
a first substrate 212 including a color film layer 2121 with a front projection in the display area; a liquid crystal layer 213; the second substrate 214, which comprises a plurality of light transmissive components 2141 with orthographic projections on the light field collection region, is configured to determine a light transmissive region of the light field collection region according to the position of the viewing user, and to open at least one light transmissive component 2141 corresponding to the light transmissive region. In addition, the display panel 210 further includes: a first polarizer 211 disposed on a light-facing side of the first substrate; and a second polarizer 215 arranged on the backlight side of the light field acquisition region in the orthographic projection of the second substrate 214.
In practical implementation, the first polarizer 211, the first substrate 212, the liquid crystal layer 213, the second substrate 214, and the second polarizer 215 of the display panel 210 are sequentially disposed along the light incident direction. The first substrate 212 and the second substrate 214 are transparent substrates, and the present embodiment is preferably a glass substrate.
In the display area, the color film layer 2121 is disposed on the corresponding first substrate 212, and the backlight module 220 is disposed behind the second polarizer 215, so as to ensure that the picture content can be normally played in the display area.
In the light field collection region, the corresponding first substrate 212 has no color film layer 2121, so that the first substrate 212 of the light field collection region is transparent in a pure color, and thus the light transmission effect can be ensured. And a plurality of light-transmitting assemblies 2141 are disposed in the light field collecting region of the second substrate 214, such that the light-transmitting assemblies 2141 can be turned off when not operating, and the liquid crystal layer 213 corresponding to the light-transmitting assemblies 2141 can keep an opaque state, and when light transmission is required, the corresponding light-transmitting assemblies 2141 are controlled to be turned on, and the light transmittance of the corresponding liquid crystal layer 213 is adjusted and controlled by the light-transmitting assemblies 2141, such that light can be transmitted through the liquid crystal layer 213 corresponding to the light-transmitting assemblies 2141. The camera array 230 is disposed on the backlight side of the second polarizer 215, so as to ensure that the camera array 230 can be used for light field collection to form a 3D image.
Through the scheme, the light field acquisition part and the display part can share the same display panel 210, so that a user can realize two functions of displaying and light field acquisition in one display device 200, and the use is convenient.
In some embodiments, as shown in fig. 2E, the light transmissive member 2141 includes:
a transparent pixel electrode 21411; a driving unit 21412 electrically connected to the transparent pixel electrode 21411 and configured to provide an electrical signal to the transparent pixel electrode 21411 to change the light transmittance of the liquid crystal layer 213 corresponding to the transparent pixel electrode 21411.
In a specific implementation, the transparent pixel electrode 21411 is made of a transparent metal, such as ITO (Indium tin oxide, Indium tin oxide transparent conductive glass film), and is uniformly and densely arranged on the light field collecting portion of the second substrate 214. After the light-transmitting area is determined, the driving unit 21412 corresponding to the light-transmitting area is controlled to start, and the driving unit 21412 is used for providing a high-level electrical signal to the transparent pixel electrode 21411, so that the transparent pixel electrode 21411 is in a high-voltage state, and further, an electric field of the liquid crystal layer 213 is changed, so that the light transmittance of the liquid crystal layer 213 is increased, and further, the light-transmitting area can be in a light-transmitting state. Thereby realizing the purpose that the light-transmitting area formed by the light-selecting structure 210b is controllable.
In some embodiments, as shown in fig. 2D, the camera array 230 is a linear array of cameras 230.
In a specific implementation, the length of the linearly arranged camera array 230 corresponds to the width of the light field collecting region, and the adjacent cameras in the camera array 230 are arranged closely, and the number of the cameras arranged in the corresponding camera array 230 may be adjusted according to the size of the cameras and the width of the light field collecting region, which is not limited herein.
In some embodiments, each camera in the camera array 230 is an RGB (Red, Green, Blue) camera.
In specific implementation, a traditional camera for collecting a 3D image is an RGBD camera, which can collect depth information of an image, and the collected image needs to be modeled based on the depth information to generate the 3D image. The display device 200 of the present embodiment uses a common RGB camera, which is less costly and the process of 3D image acquisition is simpler and faster.
Based on the same inventive concept, the present embodiment provides a light field acquisition method applied to the display device described in the above embodiments.
As shown in fig. 3A, the implementation process of the light field acquisition method includes:
In some embodiments, step 302 is divided into two cases:
first, as shown in fig. 3B and 3C:
step 3021, in response to determining that the light-transmissive region is located between the light-entrance apertures of two cameras in the camera array, treating the two cameras as a first and second target camera (e.g., first and second target cameras s +1 in fig. 3B and 3C), respectively.
Step 3022, controlling the first target camera to acquire first image information, controlling the second target camera to acquire second image information, and adding the first image information and the second image information to form 3D image information.
In particular implementations, the field of view captured by the two cameras is divided into a 0 field of view for vertical light intake (e.g., as shown in FIG. 3B) and a 1 field of view for oblique light intake (e.g., as shown in FIG. 3C). In 3D image capture, it is basically most cases that 3D image capture is performed by two cameras, and pixels of the two captured images (e.g., the photosensitive pixel s _0 and the photosensitive pixel s +1_0 of the field 0 in fig. 3B, and the photosensitive pixel s _1 and the photosensitive pixel s +1_1 of the field 1 in fig. 3C) are added to form a final 3D image. The imaging process is carried out on the display device, and the two images can be obtained by pixel addition without complex algorithm (such as viewpoint difference synthesis algorithm), so that the time delay can be reduced, and the real-time property of 3D image acquisition is further ensured.
FIG. 3D shows a schematic of two cameras and corresponding apertures for the light transmissive regions; fig. 3E shows a schematic diagram of summing pixels captured by two cameras.
In some embodiments, the adding the first image information and the second image information in step 3022 to form 3D image information specifically includes:
at step 30221, the aperture of the light-transmissive region is determined (e.g., C0 in fig. 3D and 3E).
Step 30222, adding the pixel points in the first image information (e.g., Fn 'and En' in fig. 3D and 3E) and the pixel points in the second image information (e.g., Fn +1 'and En + 1' in fig. 3D and 3E) according to the aperture of the light-transmissive region and the geometric relationship between the first target camera (e.g., Cn in fig. 3D and 3E) and the second target camera (e.g., Cn +1 in fig. 3D and 3E) to obtain a sum result.
Step 30223, filling the summation result to the pixel point imaged corresponding to the aperture of the light-transmitting area to form the 3D image information.
In specific implementation, the light-transmitting area can be set to a corresponding shape according to actual needs, and is preferably a circular area. Through the scheme, the images collected by the two cameras are added through the geometric relation, the addition algorithm is simple, the first image information and the second image information are added to the pixel points of the aperture corresponding imaging of the light-transmitting area, the 3D image information obtained in the mode is clear, and the image distortion can not occur.
Second, as shown in fig. 3F:
step 3021', in response to determining that the optically transmissive region matches an optical entrance aperture of one camera in the array of cameras, treating the one camera as a target camera.
Step 3022', controlling the target camera to perform 3D image acquisition in the light entrance aperture, so as to obtain 3D image information.
During specific implementation, the condition that the light entrance aperture of the camera is just matched with the light transmission area is relatively less, and for the condition, only 3D image acquisition is needed by using the camera, and corresponding 3D image information can be directly obtained without image addition.
In some embodiments, since the user intuitively feels from both eyes, the positions of both eyes of the viewing user are directly taken as the positions of the viewing user. This ensures that the user has a more realistic 3D visual experience.
Through the embodiment, the light transmission area is adjusted according to the position of the watching user, the camera arranged on the display device can acquire the corresponding 3D image according to the visual angle of the watching user, algorithm synthesis is not needed, the 3D image quality is guaranteed, meanwhile, the time delay time can be shortened, and the real-time performance of 3D image transmission is guaranteed.
It should be noted that the above describes some embodiments of the disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments described above and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.
Based on the same inventive concept, the embodiment provides an image data transmission method, which can be specifically applied to the process of video monitoring by a single party and the process of video call by two parties.
In the unilateral video monitoring process, the watching user is the monitoring party, and the execution subject of the method is a terminal device provided with a display device (for example, a television, a mobile phone, a tablet, a computer and the like capable of 3D image acquisition).
