Description

Technical Field

[0001] The present invention relates to the field of virtual reality technology, and in particular to a VR video playback system, method and VR glasses. Background Art

[0002] Virtual Reality (VR) technology is a computer simulation system that can create and experience a virtual world. It uses a computer to generate a simulated environment. It is a system simulation of interactive three-dimensional dynamic vision and entity behavior that integrates multi-source information, allowing users to immerse themselves in the environment.

[0003] When users use virtual reality products, they can visually experience being immersed in a virtual reality environment. VR headsets are the most common virtual reality products on the market. Generally speaking, VR headsets can be divided into three categories: external headsets, integrated headsets, and mobile headsets. Among them, mobile headsets have a simple structure and are low in price. You just need to put them in your phone to watch. Since the shell of such a mobile head-mounted display device must be closed, when the mobile phone is installed inside it, the user cannot directly operate the mobile phone. That is, when the user uses the mobile head-mounted display device to watch VR videos, since the line of sight is completely blocked, the user needs to use fingers to find the physical buttons set on the mobile head-mounted display device to perform relevant operations on the product. The user determines the function of the button based on the shape and position of the touched button, which is easy to make mistakes in use; and the operation of the product by the physical buttons on the existing mobile head-mounted display device is also limited to play, pause, fast forward and rewind, volume adjustment, etc., and does not involve adjusting the video playback angle or other functions through the physical buttons on the mobile head-mounted display device.

[0034] In order to enable those skilled in the art to better understand the scheme of the present invention, exemplary implementations or embodiments of the present invention will be described below in conjunction with the accompanying drawings. Obviously, the described implementations or embodiments are only implementations or embodiments of a part of the present invention, not all of them. Based on the implementations or embodiments of the present invention, all other implementations or embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present invention.

[0035] The embodiment of the present invention provides a VR video playback system, such as Figure 1 As shown, the system includes a VR device end and a mobile device end 20. The VR device corresponding to the VR device end is a VR glasses, which belongs to a mobile head display device. The VR glasses are provided with multiple buttons corresponding to the mobile device end 20; the mobile device corresponding to the mobile device end 20 is, for example, a smart phone, and the user sends instructions to the smart phone by operating the buttons on the VR glasses; wherein the instructions include playback adjustment instructions and shooting instructions; the playback adjustment instructions include field of view angle magnification instructions, reduction instructions or field of view angle restoration initial instructions; the shooting instructions include picture shooting instructions and short video recording instructions.

[0036] Different key combinations can be set for sending corresponding instructions. For example, two buttons are set on the outside of the VR glasses: a play adjustment button and a shooting button, which correspond to the play adjustment instruction and the shooting instruction respectively; or, four buttons are set: a field of view angle zoom in button, a field of view angle reduction button, a field of view angle restoration initial button and a shooting button, which correspond to the field of view angle zoom in instruction, zoom out instruction, field of view angle restoration initial instruction and shooting instruction respectively; or, five buttons are set: a field of view angle zoom in button, a field of view angle reduction button, a field of view angle restoration initial button, a picture shooting button and a short video recording button, which correspond to the field of view angle zoom in instruction, zoom out instruction, field of view angle restoration initial instruction, picture shooting instruction and short video recording instruction respectively.

[0037] The mobile device 20 includes a display module 210, an execution module 220 and a processing module 230. The display module 210 is used to display VR videos; the execution module 220 is used to perform corresponding playback adjustment operations according to playback adjustment instructions sent by the VR device; the processing module 230 is used to perform corresponding processing according to shooting instructions sent by the VR device to obtain pictures or short videos.

[0038] The display process of VR video in the display module 210 includes: first, a mapping layer is established, and then the video image frames are rendered onto the mapping layer in chronological order. A mapping layer refers to a canvas on which text or images can be drawn, and can be stacked in sequence to form the final effect of the view; rendering generally refers to the process of converting a certain form of graphics into a two-dimensional pixel matrix in computer graphics. It is a process of generating an image from a model and displaying data to the user in a specific way. Specifically, for each frame of VR video image, first determine the dividing point between the left view part and the right view part, establish a left eye plane mapping layer for the left view part, and establish a right eye plane mapping layer for the right view part, then render the left view part onto the left eye plane mapping layer, and render the right view part onto the right eye plane mapping layer.

[0039] When only two buttons, namely, the play adjustment button and the shooting button, are set on the VR glasses, the process of the execution module 220 executing the corresponding play adjustment operation according to the play adjustment instruction sent by the play adjustment button includes: when playing a VR video with the field of view angle as 1 times the initial value, the play adjustment button is pressed once or is pressed continuously and for a long time, then the execution module obtains a field of view angle enlargement instruction, and the field of view angle increases or gradually increases until the field of view angle of the display area is adjusted to the maximum value and no longer increases; after the field of view angle is adjusted to the maximum value, the play adjustment button is pressed once or is pressed continuously and for a long time, then the execution module obtains a field of view angle reduction instruction, and the field of view angle decreases or gradually decreases until the field of view angle of the display area is adjusted to the minimum value and no longer decreases; if the play adjustment button is double-clicked, then the execution module obtains a field of view angle restoration initial instruction, that is, the field of view angle is restored to 1 times the initial value.

[0040] When four or five buttons are set on the VR glasses, the execution module 220 executes the corresponding playback adjustment operation according to the playback adjustment instructions sent by the buttons with different functions, and the process includes: when playing a VR video with the field of view angle of 1 times the initial value, the field of view angle enlargement button is pressed once or is pressed continuously and for a long time, then the execution module obtains the field of view angle enlargement instruction, and the field of view angle increases or gradually increases until the field of view angle of the display area is adjusted to the maximum value and no longer increases; the field of view angle reduction button is pressed once or is pressed continuously and for a long time, then the execution module obtains the field of view angle reduction instruction, and the field of view angle decreases or gradually decreases until the field of view angle of the display area is adjusted to the minimum value and no longer decreases; the field of view angle restoration initial button is pressed once, then the execution module obtains the field of view angle restoration initial instruction, and the field of view angle is restored to 1 times the initial value.

[0041] When only two buttons, namely the play adjustment button and the shooting button, are set on the VR glasses, the processing module 230 performs corresponding processing according to the shooting instruction sent by the shooting button to obtain a picture or a short video. The process includes: when the shooting button is pressed once, the processing module obtains the picture shooting instruction, processes the panoramic video frame data according to the time information and angle information carried in the picture shooting instruction, and obtains a screenshot; when the shooting button is pressed continuously, the processing module obtains the short video recording instruction, processes the panoramic video frame sequence data according to the time period information carried in the short video recording instruction and the angle information of each frame, and obtains a video formed by multiple screenshots.

[0042] When five buttons are set on the VR glasses, the processing module 230 performs corresponding processing according to the shooting instructions sent by the picture shooting button and the short video recording button to obtain the process of pictures or short videos, including: when the picture shooting button is pressed once, the processing module obtains the picture shooting instruction, processes the panoramic video frame data according to the time information and angle information carried in the picture shooting instruction, and obtains a screenshot; when the short video recording button is pressed once, the processing module obtains the video recording start instruction, and when the short video recording button is pressed again after a period of time, the processing module obtains the video recording end instruction, and then processes the panoramic video frame sequence data according to the time period information from the start of video recording to the end of video recording and the angle information of each frame, and obtains a video formed by multiple screenshots.

[0043] It should be noted that buttons can be set on both sides of the top of the VR glasses, or on other locations on the VR glasses. It is more appropriate to set two buttons on the VR glasses. Setting four or five buttons will firstly cause users to confuse the button functions when touching the buttons, affecting the user experience; secondly, the design of the VR glasses is also more complicated. Of course, other different combinations can also be set according to needs.

[0044] Furthermore, the VR device corresponding to the VR device end may also include a VR handle, and the VR handle communicates with the mobile device in a wireless manner, that is, the VR glasses are not provided with buttons of corresponding functions, but the VR handle is provided with a plurality of buttons corresponding to the mobile device end 20. The buttons on the VR handle are provided in the same manner as the VR glasses.

[0045] Furthermore, in addition to buttons, the external hardware form of the VR glasses or VR controllers that sends playback adjustment instructions and shooting instructions can also be a slider or a wheel or other forms of expression.

[0046] Specifically, the specific process of processing the panoramic video frame data to obtain the screenshot according to the time information and angle information carried in the picture shooting instruction in the processing module 230 is described as follows.

[0047] Pre-store a panoramic video image frame sequence that is the same as the VR video content, that is, the time sequence and mapping angle are the same, that is, the displayed VR video image frame corresponds to the pre-stored panoramic video image frame in time and mapping angle; the angle information includes, for example, the horizontal angle and pitch angle of the corresponding mobile device, and select a frame corresponding to the current time information of the VR video or multiple frames before and after the frame in the stored panoramic video image frame sequence, and fuse the multiple frames to obtain the fused enhanced image; intercept a screenshot corresponding to the direction and angle information in the frame image or the fused enhanced image. The screenshot can be further saved as a photo image under the corresponding user account on the mobile device for the user's final preview and download.

[0048] Similar to the screenshot acquisition process corresponding to the picture shooting instruction, the specific process of processing the panoramic video frame sequence data in the processing module 230 according to the time period information from the start to the end of the video recording and the angle information of each frame to obtain a video formed by multiple screenshots is as follows: according to the time period information, select part or all of the panoramic image frames (or enhanced images) corresponding to the time period in the stored panoramic video image frame sequence as candidate images; for the selected several frames of candidate images, capture a screenshot corresponding to the angle information carried in the instruction in each frame of the candidate panoramic image; encode all the captured screenshots in chronological order to form a video file. The video file can be further saved under the corresponding user account on the mobile device for the user's final preview and download.

[0049] The method of taking screenshots in the above processing process is a known technology and will not be described in detail here.

[0050] In summary, after obtaining the shooting instruction, taking pictures or short videos of the VR video currently played by the display module 210 according to the shooting instruction is actually taking pictures or short videos of the panoramic video with the same time and mapping angle as the displayed VR video, that is, the shooting instruction includes angle information and time information, and the processing module 230 captures pictures or continuously captures multiple pictures in the panoramic video according to the angle information and time information and forms a video in sequence.
