Taking a display device as a VR head-mounted display device as an example, fig. 2 exemplarily outputs a structure diagram of the display device provided in the embodiment of the present application. As shown in fig. 2, the VR head-mounted display device includes a lens group 201 and a display 202 disposed right in front of the lens group 201, wherein the lens group 201 is composed of a left display lens 201_1 and a right display lens 201_ 2. When a user wears the VR head-mounted display device, human eyes can watch videos displayed by the display 202 through the lens group 201, and VR effects are experienced.
In the embodiment of the application, various VR scenes such as a cinema scene, a game scene, a fitness scene and the like can be preset, and a user can select the VR scenes according to requirements. The VR scene may be stored on a server or in an application local to the display device. Wherein, be provided with virtual background screen in the different VR scenes, and the width and the height of virtual background screen are different in the different VR scenes. The position of the virtual background screen is the position of video playing in the VR scene, and the area surrounded by the width and the height of the virtual background screen is the area of video playing in the VR scene. Each VR scene uniquely corresponds to a scene identifier (such as a scene ID, a scene name, a Uniform Resource Locator (URL), etc.), and the width and height of the virtual background screen in each VR scene are recorded in advance, so as to generate a configuration file. Among them, it can be recorded in the form of key-value pairs, such as [ scene ID: (width value, height value) ].
The storage location of the configuration file is not limited in the embodiment of the application, and the configuration file can be stored in a local directory of the display device or an application program.
It should be noted that, the display device in the embodiment of the present application may be, besides the VR head-mounted display device, a device capable of playing and interacting with videos, such as a smart phone, a tablet computer, a desktop computer, a notebook computer, and a smart television.
Embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 3 schematically illustrates a VR video playing scene provided by an embodiment of the present application. As shown in the VR scene in fig. 3, a virtual background screen (indicated by a thick solid line in fig. 3) is disposed on a wall of the VR scene, and when video playback is performed, a display screen (indicated by a thin dotted line in fig. 3) for displaying a VR video is limited by the virtual background screen, and when the scale of the display screen is switched, the range of the virtual background screen cannot be exceeded, so that the video is normally displayed.
Based on the scene structure shown in fig. 3, fig. 4 exemplarily shows a flowchart of a method for adjusting a display screen according to an embodiment of the present application, where the method can accurately adjust the size of the display screen when the display screen is proportionally switched in a VR scene, and the process is executed by a display device having a virtual reality function, and mainly includes the following steps:
s401: responding to the VR scene confirmation request, obtaining the width and the height of a virtual background screen in the VR scene, and respectively taking the width and the height of the virtual background screen as the initial width and the initial height of a pre-created display screen for displaying the VR video.
In the step, a user performs man-machine interaction with the display device, selects a VR scene through a function key or a touch screen of the display device, and triggers a VR scene confirmation request carrying a scene identifier of the VR scene selected by the user. And after receiving the VR scene confirmation request, the display equipment acquires the VR scene according to the scene identification.
In specific implementation, in order to improve the scene obtaining efficiency, the display device first obtains a VR scene and a configuration file from a local application according to a scene identifier, and if the VR scene and the configuration file are not obtained, sends a VR scene obtaining request to the server, and sends the VR scene and the configuration file to the display device after the server receives the VR scene obtaining request. The display device loads and displays the acquired VR scene, and reads the width (marked as background size _ w) and the height (marked as background size _ h) of the virtual background screen in the VR scene according to the configuration file so as to serve as space limitation of a display screen for subsequently displaying the video.
In S401, after the display device is started, the rendering engine creates a planar rectangular grid, where the planar rectangular grid is used as a display screen (rendering carrier) of the VR video, initializes the display screen according to the acquired VR scene and the configuration file, specifically, sets a center of the display screen to be consistent with a center of the virtual background screen, and uses a width of the virtual background screen as an initial width of the display screen and a height of the virtual background screen as an initial height of the display screen.
S402: and responding to the VR video playing request, and acquiring a target VR video according to the video identifier carried by the VR video playing request.
In this step, a user performs human-computer interaction with a display device, selects a target VR video to be played through a function key or a touch screen of the display device, and triggers a VR video playing request, where the VR video playing request carries a video identifier of the target VR video selected by the user. And after receiving the VR video playing request, the display equipment acquires a target VR video according to the video identification.
For example, the display device sends a VR video acquisition request to the server according to the URL of the target VR video, and the server sends the target VR video to the display device after receiving the VR video acquisition request.
In order to improve the video acquisition efficiency, the target VR video may be acquired from the local of the display device first, and if not, the target VR video may be acquired from the server.
Optionally, to adapt the display screen to the target VR video, in some embodiments, the resolution of the target VR video is obtained at the same time as the target VR video is obtained. The horizontal resolution of the target VR video is recorded as video _ w, and the vertical resolution is recorded as video _ h.
It should be noted that, because the widths and heights of the virtual background screens of different VR scenes are different, the default ratio of the display screen is not necessarily suitable for the current VR scene, and needs to be adjusted. The default ratio is not limited, for example, the default ratio may be a horizontal-vertical resolution ratio of the target VR video, and for example, the default ratio may be a display screen ratio of the VR video played last time.
S403: responding to the display screen proportion switching request, and adjusting the initial width and the initial height of the display screen according to the proportion type carried by the switching request to obtain the target width and the target height of the display screen.
In this step, the scale type of the display screen can be preset, and each scale type corresponds to an adjustment mode. In the embodiment of the application, the scale types of the display screen include 3 types, a filling scale, a fixed scale and a self-adaptive scale. Wherein, the ratio value in the fixed ratio is not restrictive, such as 16: 9, 16: 10, 4: 3, etc.
In S403, the user performs human-computer interaction with the display device, selects a scale type of the display screen through a function key of the display device or a touch screen, and triggers a scale switching request of the display screen, where the switching request carries the scale type selected by the user, and the display device adjusts an initial width and an initial height of the display screen according to the scale type to obtain a target width and a target height of the display screen.
Assuming that the target width of the display screen is screen size _ w, the target height is screen size _ h, the reference ratio is P1, P1 is determined according to the width and height of the virtual background screen, and P1 is background size _ w/background size _ h. Specifically, the method comprises the following steps:
when the scale type is the fill scale, the initial width of the display screen is determined as the target width of the display screen, and the initial height of the display screen is determined as the target height of the display screen, namely, screen _ w ═ background _ size _ w, and screen _ h ═ background _ size _ h.
And when the proportion type is a fixed proportion, adjusting the initial width and the initial height of the display screen according to the size of the ratio of the first target width to the first target height to obtain the target width and the target height of the display screen. The first target aspect ratio is determined according to a preset fixed ratio, and when the fixed ratio is f _ w: f _ h, the first target aspect ratio P2 is f _ w/f _ h.
In specific implementation, the reference ratio and the first target width-height ratio are compared, if the reference ratio is greater than the first target width-height ratio, the initial width of the target display screen is scaled according to the first target width-height ratio to obtain the target width of the display screen, the initial height of the display screen is determined as the target height of the display screen, if the reference ratio is less than or equal to the first target width-height ratio, the initial height of the target display screen is scaled according to the reciprocal of the first target width-height ratio to obtain the target height of the display screen, and the initial width of the display screen is determined as the target width of the display screen.
For example, when P1 > P2, in order to ensure that the display screen does not exceed the range of the virtual background screen, screen _ h is set as background screen _ h, and screen _ w is set as background screen _ h P2; when P1 is not greater than P2, screen _ w is set as background screen _ w, and screen _ h is set as background screen _ w (1/P2) in order to ensure that the display screen does not exceed the range of the virtual background screen.
