Description
Technical Field
The present invention relates to Virtual Reality (VR) technology, and in particular, to a barrage display method and system for VR video.
Background
Domestic barrage technology is started in 2007, and is represented by video websites ACFUN and Bilibili. The barrage is a very novel model, which can form simple interactivity with the viewer, who announces the perception of the video at that moment in time in text, which then becomes floating from the screen. The formation of the bullet screen marks that the video industry enters a brand new stage and is a prototype of the interactive video.
In recent years, Virtual Reality (VR) technology has been developed vigorously and is also widely used in the video field. The VR video is also called VR panoramic video and is also a video. In contrast, each frame of the VR video is a (horizontal) 360-degree x (vertical) 180-degree panoramic picture. When watching, the user is not limited to a fixed visual angle range any more, but can turn around up, down, left and right, and select the content at any angle in the whole space to watch. The reality and the sense of immersion of experience can be strengthened to the cooperation VR glasses and watch. The VR video subverts the viewing experience of common videos and also injects vitality into the further development of interactive videos.
During watching the VR video, the users also desire to communicate with each other by means of a text bullet screen. However, the traditional video bullet screen expression has the following problems:
1) traditional video barrage only relates to time axis information, if direct application in the VR video, can't satisfy the coexistence problem of time and spatial information.
2) The scenes of conventional video are fixed relative to the screen. The scene content corresponding to the bullet screen characters sent by the user at a certain time is also fixed. However, the scene of the VR video is 360 degrees, and the scene contents seen by different users at the same time are likely to be inconsistent. If the user issues bullet screen characters aiming at the content seen by the user, the user who does not see the scene in the direction cannot know the meaning specifically expressed by the user. Then the best effect cannot be achieved by means of communication through the bullet screen.
3) Conventional video banners typically appear from one end of the screen and disappear from the other. If the method is applied to VR video, characters can be cut off when split-screen watching is carried out by using VR glasses, and the problem of double images can occur when the contents of left and right screens are inconsistent.

Detailed Description
The invention is described in detail below with reference to the figures and specific embodiments. It is noted that the aspects described below in connection with the figures and the specific embodiments are only exemplary and should not be construed as imposing any limitation on the scope of the present invention.
Embodiment of display method of virtual reality video barrage
Fig. 1 shows a flow of an embodiment of a display method of a virtual reality video bullet screen of the present invention. Referring to fig. 1, the following is a detailed description of specific implementation steps of the display method of the present embodiment.
Step S1: and the VR barrage is associated with the time and space information.
VR barrage generally refers to the barrage information of characters, and is generally inputted through a user keyboard or automatically converted into characters after being inputted by a user voice.
The association operation here refers to recording a Pan value and a Tilt value of a VR video frame at a current VR video playing time point and a current screen center point when the barrage is sent, where the Pan value represents a frame horizontal direction view angle range, and the Tilt value represents a frame vertical direction view angle range.
There are many ways in which the above-described association can be achieved, and two of them are exemplified by the present invention. The first example is to acquire a Pan value and a Tilt value of a VR video picture frame at the center point of a current screen by means of finger dragging.
As shown in fig. 3, when playing a VR panorama (the panorama is a picture with a horizontal view angle within 360 degrees and a vertical view angle within 180 degrees), Pan and Tilt values at the center of the playing window correspond to Pan and Tilt values on the panorama one-to-one. Assuming that the current values of Pan and Tilt at the center of the playing window are denoted as CurPan and CurTilt, respectively, then when the finger is pressed down on the screen and moved by distances dx, dy, the moving response dPan, dTilt on the panorama is known, and then the new values of Pan and Tilt at the center of the playing window are denoted as NewPan and NewTilt, then:
NewPan＝CurPan+dPan
NewTilt＝CurTilt+dTilt
and simultaneously updating the current values of Pan and Tilt in the center of the playing window:
CurPan＝NewPan
CurTilt＝NewTilt
a simple formula for calculating dPan, dTilt from dx, dy is as follows:
dPan＝dx*coefficient
dTilt＝dy*coefficient
wherein coefficient is an empirical coefficient related to the pixel density of the mobile phone screen, for example, the value is 0.75.
A second example is to change the Pan and Tilt values of the picture frame at the center point of the screen by means of gyro sensing. A gyroscope, also called an angular velocity sensor, is different from an accelerometer (G-sensor) and measures a rotation angular velocity when a physical quantity is a yaw or a tilt. The mobile phone cannot measure or reconstruct complete 3D actions by only using an accelerometer, the G-sensor can only detect axial linear actions when the rotary actions cannot be measured. However, the gyroscope can well measure the rotation and deflection actions, so that the actual actions of a user can be accurately analyzed and judged, and then the mobile phone is correspondingly operated according to the actions.
The gyroscope in the mobile phone is called a micro-mechanical gyroscope and is also called a three-axis gyroscope, namely, the position, the moving track and the acceleration in 6 directions are simultaneously measured.
When the mobile phone rotates, a corresponding matrix M is obtained according to the measured information of the mobile phone gyroscope:
and calculating the Euler angle corresponding to the matrix M according to the conversion relation between the matrix and the Euler angle:
Yaw＝atan2(-m20,m00)
Pitch＝asin(m10)
Roll＝atan2(-m12,m11)
the Euler angles yaw and pitch correspond to Pan, Tilt values over the panorama.
Step S2: and controlling the bullet screen to appear at the position of the center point of the current screen.
Step S3: and controlling the bullet screen to disappear at the positions of the Pan value and Tilt value of the virtual reality video picture frame at the center point of the current screen when the bullet screen is sent.
As shown in fig. 4 and 5, the bullet screen appears from the center point of the screen (point B in fig. 4, i.e., the center point of the current screen where the user watches VR video) and drifts to the position (point a in fig. 4) where the text is transmitted, and disappears after a few seconds of pause. In the process of barrage drifting, because VR video content is 360 degrees diversified multi-angle, user's sight also can begin to move from the screen center along with the direction that the barrage drifted. The position where the bullet screen stops drifting is the position where the bullet screen is sent, and the content of the bullet screen is matched with the content of the picture frame. The viewer can find out the interested content source through the bullet screen display mode, and the requirements of accurately acquiring information and exchanging information among users with the same interest point are met.
Another benefit of the bullet screen emerging from the center point of the screen is: when split screen is watched in VR glasses, the same bullet screen appears from the center of the screen of the left screen and the right screen at the same time, and moves to the same direction and disappears at the same time. The moving range of the barrage is also in the respective screen area, and no double image exists under the condition of binocular viewing.
Embodiments of a display system for a virtual reality video bullet screen
Fig. 2 illustrates the principles of an embodiment of the virtual reality video bullet screen display system of the present invention. Referring to fig. 2, the display system of the present embodiment includes: the system comprises a correlation module 1, a bullet screen appearance control module 2 and a bullet screen disappearance control module 3.
The association module 1 associates the VR barrage with time and space information, that is, records a Pan value and a Tilt value of a virtual reality video frame of a current virtual reality video playing time point and a current screen center point when the barrage is sent, wherein the Pan value represents a frame horizontal direction view angle range, and the Tilt value represents a frame vertical direction view angle range.
In addition, the system also comprises a bullet screen input module 4, wherein the VR bullet screen generally refers to bullet screen information of characters, and is generally input through a keyboard of a user or automatically converted into characters after being input by voice of the user.
There are many ways in which the above-described association can be achieved, and two of them are exemplified by the present invention. The first example is to acquire a Pan value and a Tilt value of a VR video picture frame at the center point of a current screen by means of finger dragging.
As shown in fig. 3, when playing a VR panorama (the panorama is a picture with a horizontal view angle within 360 degrees and a vertical view angle within 180 degrees), Pan and Tilt values at the center of the playing window correspond to Pan and Tilt values on the panorama one-to-one. Assuming that the current values of Pan and Tilt at the center of the playing window are denoted as CurPan and CurTilt, respectively, then when the finger is pressed down on the screen and moved by distances dx, dy, the moving response dPan, dTilt on the panorama is known, and then the new values of Pan and Tilt at the center of the playing window are denoted as NewPan and NewTilt, then:
NewPan＝CurPan+dPan
NewTilt＝CurTilt+dTilt
and simultaneously updating the current values of Pan and Tilt in the center of the playing window:
CurPan＝NewPan
CurTilt＝NewTilt
a simple formula for calculating dPan, dTilt from dx, dy is as follows:
dPan＝dx*coefficient
dTilt＝dy*coefficient
wherein coefficient is an empirical coefficient related to the pixel density of the mobile phone screen, for example, the value is 0.75.

and calculating the Euler angle corresponding to the matrix M according to the conversion relation between the matrix and the Euler angle:
Yaw＝atan2(-m20,m00)
Pitch＝asin(m10)
Roll＝atan2(-m12,m11)
the Euler angles yaw and pitch correspond to Pan, Tilt values over the panorama.
And the bullet screen appearance control module 2 controls the bullet screen to appear at the position of the current screen center point.
And the bullet screen disappearance control module 3 controls the bullet screen to disappear at the positions of the Pan value and Tilt value of the virtual reality video picture frame at the center point of the current screen when the bullet screen is sent.
As shown in fig. 4 and 5, the bullet screen appears from the center point of the screen (point B in fig. 4, i.e., the center point of the current screen where the user watches VR video) and drifts to the position (point a in fig. 4) where the text is transmitted, and disappears after a few seconds of pause. In the process of barrage drifting, because VR video content is 360 degrees diversified multi-angle, user's sight also can begin to move from the screen center along with the direction that the barrage drifted. The position where the bullet screen stops drifting is the position where the bullet screen is sent, and the content of the bullet screen is matched with the content of the picture frame. The viewer can find out the interested content source through the bullet screen display mode, and the requirements of accurately acquiring information and exchanging information among users with the same interest point are met.
