Description
Technical Field
The invention relates to the technical field of virtual reality, in particular to a 3D video image processing method, a server and a client.
background
VR (Virtual Reality) Virtual Reality provides a technique of providing an immersive sensation in an interactive three-dimensional environment generated on a computer by comprehensively using a computer graphics system and various interface devices for Reality and control. The virtual reality technology can create a computer simulation system for experiencing a virtual world, and a multi-source information fusion interactive three-dimensional dynamic scene and entity behavior simulation environment is generated by a computer, so that a user is immersed in the environment.
The 3D video (stereo film) utilizes the visual angle difference and convergence function of the eyes of people to generate a stereo effect, and the technical means of special glasses of audiences or radial semi-cone lens gratings in front of a screen and the like are adopted during the video projection, so that the left eye of the audiences sees the picture shot from the left visual angle, the right eye of the audiences sees the picture shot from the right visual angle, and the three-dimensional video is synthesized into a stereo image through the convergence function of the eyes.
At present, 3D video is developed mature, resources are rich, the aspect ratio of 3D video coding is generally 16:9 or 4:3, a player plays 3D images of the 3D video according to a left-right format or a top-bottom format, the binocular pictures of the 3D images in the player are not mixed, and are divided left, right or top-bottom, wherein the 3D images in the left-right format and the top-line format are shown in fig. 1. When the normal 3D content is played, if the aspect ratio of the left format and the right format is 16:9, the image scale is changed to 8:9 after the mixing through the glasses, resulting in image distortion, such as the video frames of the left format and the right format in fig. 3. Similarly, if the left-right format aspect ratio is 4:3, the image scale becomes 2:3 after blending through glasses, which also causes image distortion. Before playing the video in the top and bottom formats, the top and bottom frames need to be split and spliced into the left and right formats, and then played. If the aspect ratio of the top and bottom format is 16:9, after segmentation and splicing, the image proportion is changed to 32:9 after mixing through glasses, and image deformation is caused, such as the video frame of the top and bottom format in fig. 4. Similarly, if the aspect ratio of the top and bottom formats is 4:3, the image scale becomes 8:3 after blending through glasses, which also causes image distortion. In order to obtain a 3D picture satisfying the aspect ratio 16:9 of the 3D video coding of the human brain, the picture size of the player needs to be adaptively adjusted when the terminal plays, for example, the vertical size of the left and right format 3D image in fig. 2 is shortened to half when the player plays, so that the ratio of 16:9 can be satisfied when the human retina is imaged, and the image is not seriously distorted. It can be seen that this playing method of 3D video results in a loss of information amount due to the adjustment of the picture size by the player during playing, resulting in a decrease in bandwidth utilization.
disclosure of Invention
The embodiment of the invention provides a 3D video image processing method, a server and a client, which are used for solving the problem that the bandwidth utilization rate is reduced due to the fact that the information quantity is lost because the picture size is adjusted when a player plays in the existing 3D video playing method.

Detailed Description
in order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Since the video coding length-width ratio of the existing left-right format 3D video frame is generally 16:9 or 4:3, the resolution is commonly 1920 × 1080, 1280 × 720, 2560 × 1440 and 3840 × 2160, the left-right format 3D video is played by using a mobile phone, the mobile phone is put into VR glasses, and the left picture of the left eye and the right picture of the right eye are seen by the right eye with good interpupillary distance and focal length. As shown in fig. 3, an image having an out-of-screen effect, such as the composite image in the 8:9 aspect ratio format of fig. 3, is then synthesized in the human brain. Since 3D video frames in the format of left and right 16:9 are directly viewed by this playing method, the human scale is perceived to be distorted, which affects the viewing effect. The conventional common solution is to adjust the size of a picture in a mobile phone player and reduce the longitudinal size of a video by half, so that the picture with the length-width ratio of 16:9 is synthesized in the human brain, the proportion of characters is normal, and a good sensory effect is achieved. The solution flow is shown in fig. 2. Obviously, the method for reducing the vertical size by using the mobile phone player is essentially to perform interlaced sampling on a video picture, only half of data is displayed, and the other half of data is discarded. Therefore, only 50% of the information is utilized and 50% of the information is lost. Because the information content is lost by 50%, the picture quality is affected, and poor experience is caused.
Similarly, for the top-bottom format 3D video, it means that two pictures of the 3D video are arranged in a top-bottom manner, as shown in fig. 1, because the top-bottom format 3D video frame is a video frame that is equally divided into two almost equal parts from the middle horizontal direction, with a slight difference. The aspect ratio of a video is generally 16:9 or 4:3, the resolutions are usually four types, namely 1920X1080, 1280X720, 2560X1440 and 3840X2160, a mobile phone is used for playing a top-bottom format 3D video, a special player is needed to adjust top-bottom format video pictures into left-right format video pictures, then the mobile phone is placed in VR glasses, the pupil distance and the focal length are good, so that a left picture is seen by a left eye, and a right picture is seen by a right eye, as shown in fig. 4, because the ratio of the video with the screen-out effect synthesized by the method in the human brain is 32:9, the aspect ratio of the video in the video picture is not standard 16:9 or 4:3, the ratio of people is deformed, and the viewing effect is also affected. Therefore, in order to solve the problem, the existing solution is to adjust the size of the picture in the mobile phone player, and reduce the horizontal size of the video by half, so that a picture with an aspect ratio of 16:9 is synthesized in the human brain, and thus the proportion of people is normal, and a good watching effect is achieved. Obviously, the disadvantage of the method for adjusting the picture size by using the mobile phone player is the same as that of the left and right format video, and is not described again.
In order to solve the problems in the prior art, an embodiment of the present invention provides a schematic flow chart of a 3D video image processing method from a server side, where the method is executed by a server, and referring to fig. 5, a specific implementation method includes:
step S101, receiving a 3D video playing request sent by a client, wherein the 3D video playing request comprises a video source identifier to be played and the resolution of a display screen of the client.
and step S102, determining a video source set of the video coding length-width ratio corresponding to the video source identifier to be played according to the video source identifier to be played.
step S103, determining a video source matched with the resolution of the display screen of the client according to the playing format of each video source in the video source set and the resolution of the display screen of the client.
In step S104, the video source matched with the resolution of the display screen of the client is sent to the client.
That is, the client sends a 3D video playing request to the video server, for example, the request includes a 3D movie name: amantad, and the client also includes the resolution of its own display screen in the request, for example, 1920X1080, so that the video server finds video sources with different resolutions according to amantad, where the playing format of each frame of image of some video sources is the top-bottom format, and the playing format of each frame of image of some video sources is the left-right format, but it should be noted that, for the video sources with the left-right format, such video sources have been preprocessed into formats with video coding aspect ratios of 32:9, for example, 4 formats such as 1920X540, 1280X360, 2560X720, 3840X 1080; for video sources whose playback format is top-bottom format, such video sources have been pre-processed into a format with a video encoding aspect ratio of 8:9, such as 4 formats of 960X1080, 640X720, 1280X1440, 1920X 2160. And then determining a video source matched with the resolution of the display screen of the client from a video source set containing different resolutions. Therefore, the client can correspondingly play the video source, the video source synthesizes a picture with the aspect ratio of 16:9 in the human brain, the character proportion is normal, a good watching effect is achieved, image adjustment is not needed, and each pixel point of an original video frame is fully utilized because the resolution ratio of the video source is matched with that of a display screen of the client, after transmission and decoding, the video source is mapped with each pixel point of the screen of the client one by one, and the information utilization rate reaches 100%.
further, the 3D video playing request further includes: the playing format of a video source to be played;
Determining a video source matched with the resolution of the display screen of the client according to the playing format of each video source in the video source set and the resolution of the display screen of the client, wherein the determining comprises the following steps:
if the playing format of the video playing request is a left-right format, determining a first video source set with a video coding length-width ratio of 32 to 9 from the video source sets;
And according to the resolution of a display screen of the client side of the video playing request, determining a target video source with a longitudinal resolution of a video source being half of the longitudinal resolution of the display screen and a transverse resolution being consistent with the transverse resolution of the display screen from a first video source set.
for example, a dedicated player is not installed on the client, so that the client actively sends a video playing request with a left-right format to the video server, and thus the video server filters out video source sets with left-right formats, for example, video sources with video resolutions of 1280X360, 1920X540, 2560X720, and 3840X1080 with left-right formats. Because the client also reports the resolution of the screen of the client synchronously, when the playing format is a left-right format, the principle that the longitudinal resolution of the client is half of the longitudinal resolution of the display screen needs to be satisfied, and when the horizontal resolutions are the same, the video source is the most appropriate video source, and pixels in the video source can be played in the player of the client without being lost completely, wherein, the table one indicates the corresponding relation between the longitudinal resolution of the client and the video resolution.
table 1:
| client longitudinal resolution | resolution of video source |
| 720 | 1280X360 |
| 1080 | 1920X540 |
| 1440 | 2560X720 |
| 2160 | 3840X1080 |
Further, if the playing format of the video playing request is a top-bottom format, determining a second video source set with a video coding length-width ratio of 8 to 9 from the video source sets; and according to the resolution of a display screen of the client side of the video playing request, determining a target video source with the longitudinal resolution consistent with the longitudinal resolution of the display screen and the transverse resolution consistent with the transverse resolution of the display screen from a second video source set.
For example, the client is installed with a dedicated player, so that the client actively sends a video playing request with a playing format of top-bottom format to the video server, and thus the video server filters out a set of video sources with a playing format of top-bottom format, for example, filters out video sources with a playing format of top-bottom format and video resolutions of 640X720, 960X1080, 1280X1440, 1920X2160, respectively. Because the client also reports the resolution of the screen of the client synchronously, when the playing format is the top-bottom format, the principle that the longitudinal resolution of the client is consistent with the longitudinal resolution of the display screen needs to be satisfied, and when the horizontal resolution is the same, the video source is the most appropriate video source, and pixels in the video source can be played in the player of the client without being lost completely, wherein the table two indicates the corresponding relation between the longitudinal resolution of the client and the video resolution.
Table 2:
And further, sending the data of the video source to be played to a client, decoding the data at the client, and separating a left eye image and a right eye image from each frame of image so as to enable the client to play and correctly display the video source.
therefore, by adopting the method provided by the embodiment of the invention, compared with the existing 3D video frame with the video coding length-width ratio of 16:9, the method makes full use of each pixel point of the original video frame, and after transmission and decoding, the pixel points are mapped with each pixel point of the client screen one by one, and the information utilization rate reaches 100%. As shown in fig. 6, for example, a mobile phone with a screen resolution of 1920X1080 requests a server to obtain 3D left and right format video with a resolution of 1920X 540. After network transmission and decoding, the video occupies a size of 1920X540 pixels on a screen for display, compared with a 3D video with the same code rate, the definition is improved by 1 time compared with that of a 16:9 video, and the watching effect is improved remarkably. In addition, compared with the same definition, the code rate is reduced by 50%, the server cost is effectively reduced, the network bandwidth requirement is reduced, and the blockage is reduced.
in addition, an embodiment of the present invention provides a schematic flow chart of a 3D video image processing method from a client side, where the method is executed by the client side, and as shown in fig. 7, the method specifically implemented includes:
Step S201, sending a 3D video playing request to a server, wherein the 3D video playing request comprises a video source identifier to be played and the resolution of a display screen of a client, so that the server determines a video source set with a video coding length-width ratio corresponding to the video source identifier to be played according to the video source identifier to be played, and determines a video source matched with the resolution of the display screen of the client according to the playing format of each video source in the video source set and the resolution of the display screen of the client;
Step S202, receiving a video source which is sent by the server and is matched with the resolution of the display screen of the client.
