When seeing video, positive picture has advanced a period of time automatically.So, user can only just track an event
Thing line, method useless is not on the premise of influenceing to watch front video pictures while watches oneself other videos picture interested
Face.
The content of the invention
A kind of film based on virtual reality video is provided it is an object of the invention to overcome deficiency of the prior art
Story retrogressive method.
To achieve the above object, on the one hand, a kind of film story backtracking based on virtual reality video provided by the invention
Method, comprise the following steps：
Preset initial main perspective；
When user perspective leave it is described preset it is big between initial main perspective and the user perspective and the initial main perspective
When predetermined angle difference, it is considered as and deviates visual angle state；
T is recorded as at the time of the user perspective is in when deviateing visual angle state；
When user perspective returns to the default initial main perspective and stops operating, video traces back to the t automatically
Play out.
Preferably, when the user perspective is in deviation visual angle state and the user perspective is by described default first
When holding rotation does not stop during beginning main perspective, then the record of the t is removed.
Preferably, after the record of the t is removed, until when the user perspective stops operating, by active user
Visual angle is considered as new main perspective.
According to a kind of film story retrogressive method based on virtual reality video provided by the invention, user is using virtual
When Reality glasses watch panoramic video, front video pictures can be left at any time, looked for the presence or absence of interested its
His angle picture, and viewing is can do by myself less than complete front video pictures without worry --- because when user returns to front
When video pictures are 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 originally interrupted after oneself other angle picture interested has been watched
The time point of picture continues to watch, thus can not influence watch front video pictures on the premise of and meanwhile watch oneself feel it is emerging
Other video pictures of interest.
Embodiment
Embodiments of the invention are described below in detail, term " first ", " second " are only used for describing purpose, without being understood that
To indicate or implying relative importance or the implicit quantity for indicating indicated technical characteristic.Thus, define " first ",
One or more this feature can be expressed or be implicitly included to the feature of " second ".In the description of the invention, it is " more
It is individual " two or more are meant that, unless otherwise specifically defined.
In the present invention, unless otherwise clearly defined and limited, term " installation ", " connected ", " connection ", " fixation " etc.
Term should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected, or be integrally connected；It can be machine
Tool connects or electrical connection；Can be joined directly together, can also be indirectly connected by intermediary, can be two members
Connection inside part.For the ordinary skill in the art, above-mentioned term can be understood in this hair 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 following step
Suddenly：
Preset initial main perspective；
When user perspective leave it is described preset it is big between initial main perspective and the user perspective and the initial main perspective
When predetermined angle difference, it is considered as and deviates visual angle state；
T is recorded as at the time of the user perspective is in when deviateing visual angle state；
When user perspective returns to the default initial main perspective and stops operating, video traces back to the t automatically
Play out.
Specifically, the selection mode of main perspective is formulated first：
It is to preset initial main perspective that film gives tacit consent to the visual angle commenced play out at first；
(in this reality after user perspective rotates and is more than predetermined angle difference between user perspective and initial main perspective
Apply in example is 45 °), then it is assumed that the user perspective has had deviated from presetting initial main perspective；
Turn further back after user perspective is in deviation visual angle state and user perspective deviates and presets initial main perspective,
Or turn to enclose until close to rotation one toward a direction always, if the differential seat angle between user perspective and default initial main perspective
When absolute value is less than predetermined angle difference (being in the present embodiment 45 °), then it is assumed that user perspective, which has returned to, presets initial main view
Angle；
When user perspective exceedes in deviation visual angle state and user perspective in the quiescent time of a new view position
After preset time value (being in the present embodiment 5 minutes), then current user perspective is set to new main perspective.It is appreciated that
Preset time value is one of adjusting parameter for being directed to Consumer's Experience, in actual applications can flexible transformation.
Specifically, the data that the anglec of rotation at visual angle is provided by gyroscope are calculated：First obtain gyroscope and
The concrete numerical value of accelerometer, then using EKF algorithms, (Extended Kalman Filter's is write a Chinese character in simplified form, i.e., spreading kalman is filtered
Ripple device) data of gyroscope and accelerometer are modified, according to algorithm acquired results, you can calculate the anglec of rotation at visual angle
The differential seat angle of degree, direction of rotation and 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, which enters, deviates visual angle state, t is recorded as at the time of will now, when user regards
Angle is turning not stopping operating after initial main perspective or new main perspective by presetting for one week, and is to maintain rotation and again
When 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 used as " main perspective ", then removes original " main perspective ", and empties the t recorded originally.
Specifically, after the record of t is removed, until when user perspective stops operating again, current user is regarded
Angle is considered as next new main perspective.
Particularly, " user perspective is by presetting initial main perspective " described above, " process " herein is defined as currently
The registration of user perspective and the main perspective of original t reaches more than certain proportion (such as " warp defined in the present embodiment
Cross " be when registration reaches 2/3).
To sum up, this film story retrogressive method based on virtual reality video, user are seen using virtual reality glasses
When seeing panoramic video, front video pictures can be left at any time, look for whether there is other angle pictures interested,
And viewing is can do by myself less than complete front video pictures without worry --- because entering when user returns to front video pictures
When row viewing, front video pictures directly can be traced back to that time point when user perspective leaves by this method, that is, be used
Family be able to can be returned to after oneself other angle picture interested has been watched the front video pictures that originally interrupted when
Between point continue to watch, thus on the premise of not influenceing to watch front video pictures while oneself interested other can be watched
Video pictures.
