Preset initial main perspective；
When user perspective leave described preset initial main perspective and between described user perspective and described initial main perspective big
When predetermined angle difference, it is considered as deviateing visual angle state；
Moment when described user perspective is in deviation visual angle state is recorded as t；
When user perspective returns to described default initial main perspective and stops operating, video traces back to described t automatically
Play out.
Preferably, it is in deviation visual angle state and described user perspective through at the beginning of described presetting when described user perspective
When keeping rotation not stop during beginning main perspective, then remove the record of described t.
Preferably, when after the record removing described t, during until described user perspective stops operating, by active user
Visual angle is considered as new main perspective.
A kind of based on virtual reality video the film story retrogressive method provided according to the present invention, user is virtual in use
The when of Reality glasses viewing panoramic video, front video pictures can be left at any time, look for whether existing interested its
His angle picture, and viewing of not worrying can do by myself less than complete front video pictures because when user returns to front
The when that video pictures being watched, when front video pictures directly can be traced back to that when user perspective leaves by this method
Between point, i.e. user can return to the positive plane video that originally interrupted after having watched oneself other angle picture interested
The time point of picture continues viewing, thus can watch oneself sense on the premise of not affecting viewing front video pictures emerging simultaneously
Other video pictures of interest.
Detailed description of the invention
Embodiments of the invention are described below in detail, and term " first ", " second " are only used for describing purpose, and are not understood that
For indicating or imply relative importance or the implicit quantity indicating indicated technical characteristic.Thus, define " first ",
The feature of " second " can express or implicitly include one or more this feature.In describing the invention, " many
Individual " it is meant that two or more, unless otherwise expressly limited specifically.
In the present invention, unless otherwise clearly defined and limited, term " install ", " being connected ", " connection ", " fixing " etc.
Term should be interpreted broadly, and connects for example, it may be fixing, it is also possible to be to removably connect, or be integrally connected；It can be machine
Tool connects, it is also possible to be electrical connection；Can be to be joined directly together, it is also possible to be indirectly connected to by intermediary, can be two units
Connection within part.For the ordinary skill in the art, can understand that above-mentioned term is at this as the case may be
Concrete meaning in bright.
One embodiment of the invention provides a kind of film story retrogressive method based on virtual reality video, including walking as follows
Rapid:
Preset initial main perspective；
When user perspective leave described preset initial main perspective and between described user perspective and described initial main perspective big
When predetermined angle difference, it is considered as deviateing visual angle state；
Moment when described user perspective is in deviation visual angle state is recorded as t；
When user perspective returns to described default initial main perspective and stops operating, video traces back to described t automatically
Play out.
Specifically, the selection mode of main perspective is first formulated:
Film gives tacit consent to the visual angle commenced play out at first for presetting initial main perspective；
When user perspective rotate and between user perspective and initial main perspective more than predetermined angle difference after (in this reality
Execute in example is 45 °), then it is assumed that this user perspective has had deviated from presetting initial main perspective；
Turn further back after user perspective is in deviation visual angle state and initial main perspective is preset in user perspective deviation,
Or turn toward a direction always and rotate a circle until close, if the differential seat angle between user perspective and default initial main perspective
Absolute value is less than (being 45 ° in the present embodiment) during predetermined angle difference, then it is assumed that user perspective has returned to preset initial master and regarded
Angle；
When user perspective be in deviation visual angle state and user perspective exceed in the quiescent time of a new view position
After preset time value (being 5 minutes in the present embodiment), then current user perspective is set to new main perspective.It is appreciated that
Preset time value is one of adjustment parameter for Consumer's Experience, in actual applications can flexible transformation.
Specifically, the data that the anglec of rotation at visual angle is given by gyroscope are calculated: first obtain gyroscope and
The concrete numerical value of accelerometer, (Extended Kalman Filter writes a Chinese character in simplified form, i.e. spreading kalman filter then to use EKF algorithm
Ripple device) data of gyroscope and accelerometer are modified, according to algorithm acquired results, the anglec of rotation at visual angle can be calculated
Degree, direction of rotation and the differential seat angle of relative main perspective.
Usually, the interval of the first predetermined angle difference and the second predetermined angle difference is between 30 °～180 °.
Specifically, when user perspective enters deviation visual angle state, the moment now is recorded as t, when user regards
Angle does not stop operating having turned one week after presetting initial main perspective or new main perspective, and is to maintain rotation again
The when of leaving default initial main perspective or new main perspective, then it is assumed that user be not intended to again by original default initial main perspective or
New main perspective is as " main perspective ", then removes original " main perspective ", and empties the t of original record.
Specifically, when after the record removing t, during until user perspective stops operating again, current user is regarded
Angle is considered as next new main perspective.
Particularly, " user perspective is through presetting initial main perspective " mentioned above, " process " herein is defined as currently
User perspective reaches more than certain proportion (such as " warp defined in the present embodiment with the registration of the main perspective of original t
Cross " be when registration reaches 2/3).
To sum up, this film story retrogressive method based on virtual reality video, user is using virtual reality glasses sight
The when of seeing panoramic video, front video pictures can be left at any time, look for whether there are other angle pictures interested,
And viewing of not worrying can do by myself less than complete front video pictures because entering when user returns to front video pictures
The when of row viewing, front video pictures directly can be traced back to that time point when user perspective leaves by this method, i.e. uses
The front video pictures that family can be able to return to originally to interrupt after having watched oneself other angle picture interested time
Between point continue viewing, thus can watch oneself interested other on the premise of not affecting viewing front video pictures simultaneously
Video pictures.
