Brief description
Fig. 1 is the flow chart of the scenery control implementation method preferred embodiment of VR video play device of the present invention.
Fig. 2 is that the scenery control of VR video play device of the present invention realizes the structured flowchart of system preferred embodiment.
Specific embodiment
The present invention provides a kind of scenery control realization method and system of VR video play device, for making the mesh of the present invention
, technical scheme and effect clearer, clear and definite, the present invention is described in more detail below.It should be appreciated that it is described herein
Specific embodiment only in order to explain the present invention, be not intended to limit the present invention.
As shown in figure 1, the stream of the scenery control implementation method preferred embodiment for VR video play device of the present invention
Cheng Tu, the method comprising the steps of：
Step S100, by gravity sensor obtain VR video play device accekeration, and by gyroscope acquisition VR regard
The magnitude of angular velocity of frequency playing device；
Step S200, according to described accekeration obtain scaling, current to VR video play device according to scaling
Picture correspondence zooms in and out；Wherein, described scaling is the change ratio that current picture is with respect to initial full screen pictures；
Step S300, judge that whether scaling is more than 1, when scaling is more than 1, then obtained according to described magnitude of angular velocity flat
Move distance and translation direction, and according to translation distance and translation direction, the picture after VR video play device scaling is put down
Move.
In embodiments of the invention, obtain the accekeration of VR video play device by gravity sensor, and pass through top
Spiral shell instrument obtains the magnitude of angular velocity of VR video play device, determines pantograph ratio further according to described accekeration and described magnitude of angular velocity
The translation distance of example and picture and translation direction.Obviously, when described scaling is more than 1 then to VR video play device
Current picture correspondence is amplified, and then the current picture of VR video play device is corresponded to when described scaling is less than 1
Row reduces.Because the size of initial full screen pictures is fixing, therefore in order to ensure the current picture to VR video play device
Scaling is linear to be changed, therefore defining scaling is the change ratio that current picture is with respect to initial full screen pictures.
Intelligent terminal（As smart mobile phone）When playing 3D video, it is all that transverse screen is placed, and the left side of display screen and right side
There is size identical video visibility region, namely invisible beyond the picture of this video visibility region.Due to being in intelligent terminal
The gravity sensor of middle setting and gyroscope, when driving intelligent terminal motion by rotating VR box, then according to this motion
Corresponding accekeration and magnitude of angular velocity adjust accordingly determining the current picture to VR video play device.So, use
When family need to adjust the picture size in intelligent terminal and play visual angle, only need to be can achieve by moveable head.
Under intelligent terminal transverse screen state, the X-axis of gravity sensor is the above-below direction with respect to user to gravity sensor,
The Y-axis of gravity sensor is the left and right directions with respect to user, and the Z axis of gravity sensor are the fore-and-aft directions with respect to user.
Likewise, gyroscope X-axis of gyroscope under intelligent terminal transverse screen state is the above-below direction with respect to user, the Y of gyroscope
Axle is the left and right directions with respect to user, and the Z axis of gyroscope are the fore-and-aft directions with respect to user.Therefore gravity sensor can be passed through
The accekeration recording determining scaling, and the magnitude of angular velocity being recorded according to gyroscope determine picture translation distance and
Translation direction.
Preferably, described step S200 specifically includes：
Step S201, acquisition Z axis component of acceleration on the Z axis of gravity sensor for the accekeration, and divided according to Z axis acceleration
Amount obtains gravity sensor Z axis displacement；
Step S202, according to gravity sensor Z axis displacement and gravity sensor Z axis displacement-pantograph ratio system set in advance
Number, obtains scaling；
Step S203, the display size according to initial full screen pictures, and described scaling zooms in and out to current picture, obtains
Picture after scaling.
Specifically, it is oriented Z axis positive direction if selecting perpendicular to user's face and away from facial, therefore when user is by initial
During the advance the puck of position, then scaling is more than 1, and when user is moved backwards by initial position, then scaling is less than 1.
It is, when user moves forward, picture can become big gradually, but have a full-size, if reaching maximum
After size, would not be further continued for becoming big.When user is moved rearwards by, picture can diminish gradually, equally also has a minimum chi
Very little, if after reaching minimum dimension, do not continue to diminish yet.Typically, the scope of scaling can be set to 0.5-2.
Preferably, described step S300 specifically includes：
Step S301, judge that whether scaling is more than 1；
Step S302, when scaling be more than 1 when, then obtain X-axis angular speed in the X-axis of gyroscope for the described magnitude of angular velocity and divide
Amount, and the Y-axis angular velocity component in the Y-axis of gyroscope；
Step S303, X-axis is obtained according to described X-axis angular velocity component and default gyroscope X-axis angular speed-X axis displacement
To displacement；Y-axis position is obtained according to described Y-axis angular velocity component and default gyroscope Y-axis angular speed-Y-axis displacement
Move；
Step S304, according to described X axis displacement and described Y-axis displacement, obtain translation distance and translation direction；
Step S305, according to translation distance and translation direction, the picture after VR video play device scaling is translated.
If in step s 200, the scaling of acquisition is less than 1, the picture after reducing can be complete in video visibility region
Display, need not again execution step S301-S305 to realize the translation of picture.
Specifically, when obtaining X-axis angular velocity component it is determined that picture translation distance to the left or to the right and translation side
To；When obtaining Y-axis angular velocity component it is determined that picture translation distance up or down and translation direction.For example, work as user
By travel forward picture is amplified to initial full screen pictures 2 times when cannot continue to amplify, the content of picture may exceed
Can viewing area, just have because beyond video visibility region a part image content can not show any more, and cropped fall.At this moment use
If family rotates head, intelligent terminal will detect this rotate it is also possible to picture to the left or to the right or upwards or to
Under rotated.So user can feel the change that the action of body also can truly embody on picture, allows people to feel
Place oneself in the midst of wherein.
Preferably, described step S305 specifically includes：
Step S3051, judge that the picture after described scaling exceeds the spacing of initial full screen pictures and whether is more than translation distance；
The spacing that step S3052, picture after described scaling exceed initial full screen pictures is more than described translation distance, then basis
Described translation distance and translation direction translate to the picture after VR video play device scaling；
Step S3053, being smaller than or equal to described translation distance beyond initial full screen pictures of picture after described scaling,
Then according to the picture after described scaling exceed the spacing of initial full screen pictures and translation direction to VR video play device scaling after
Picture translated.
It can be seen that, the present invention passes through gravity sensor and gyroscope senses the head movement of user, with real time to the picture play
Face zooms in and out or translates, and need not be realized by knob-operated, facilitates user's adjust automatically picture.
Based on said method embodiment, the present invention also provides a kind of scenery control of VR video play device to realize system.
