具体实施方式
下面结合本申请实施例中的附图对本申请实施例进行描述。
为了更好的理解本申请实施例公开的一种弹幕播放方法、相关设备及存储介质，下面首先对本申请实施例适用的网络架构进行描述。
请参见图1，图1是本申请实施例公开的一种弹幕播放系统的框架示意图。如图1所示，所述弹幕播放系统包括电子设备和便携设备，图1中还包括在VR虚拟空间中渲染的弹幕层以及视频层。
其中，电子设备可以包括，但不限于：智能手机，平板电脑以及个人数字助理PDA。电子设备上安装有虚拟现实(Virtual Reality，VR)应用程序(Application，APP)，该VR APP中集成有VR SDK(Software Development Kit，软件开发工具包)。在VR SDK中集成VR弹幕层的绘制能力，以及弹幕位置实时计算及刷新的能力。用户点击以启动VR APP之后，电子设备可以在VR的虚拟空间中绘制视频层并播放视频。如果用户选择采用VR弹幕方式播放弹幕，电子设备可以利用VR SDK获取用户设置的弹幕层绘制参数(比如弹幕层的高度、弹幕层的半径以及弹幕层的弧度)，根据该弹幕层绘制参数，在视频层的上方绘制环形透明的弹幕层，其中，弹幕层的高度大于或等于视频层的高度。在需要播放弹幕时，将每条实时弹幕的弹幕信息(比如弹幕内容、弹幕高度、弹幕运动速度)传递到VR SDK，可以由VR SDK实时计算出每条弹幕的三维坐标，最后，即可在VR虚拟空间，根据该三维坐标，在绘制好的弹幕层上刷新并播放实时弹幕。
在VR虚拟空间绘制的弹幕层可以被划分为多个区域，比如新生弹幕区、主屏弹幕区以及历史弹幕区，每条新产生的实时弹幕，从新生弹幕区出现，匀速移动至主屏弹幕区，再移动至历史弹幕区消逝。
其中，便携设备可以为VR眼镜，用户佩戴该VR眼镜之后，即可看到在VR虚拟空间上渲染的实时弹幕。
在图1所描述的弹幕播放系统中，弹幕区域摆脱了电子设备的屏幕的限制，弹幕层的高度大于视频层的高度，其中，视频层的区域面积即屏幕的面积。图1中所述的弹幕层，相比较于原有的弹幕区域，在纵向上扩展了新的弹幕区域，可用于实现高峰期弹幕的纵向分散，使得用户在体验高峰弹幕的同时，享受视频高能片段本身的内容，同时，弹幕层在横向上也扩展了新的弹幕区域，用户向右转头时，可以在新生弹幕区提前观看新产生的弹幕，让用户有期待感；用户向左转头时，可以在历史弹幕区回顾历史弹幕，让用户有怀旧感，因此，采用图1所示的弹幕形式，不仅可以在纵向上分流弹幕，减少弹幕高峰压力，提高视频内容的观看效果，同时，还可以丰富弹幕的渲染形式，提高用户体验。
基于前述实施例，下面阐述本申请实施例涉及的弹幕播放方法。
请参见图2，图2是本申请实施例公开的一种弹幕播放方法的流程示意图。如图2所示的弹幕播放方法应用于如上图1所示的电子设备中，所述方法包括如下步骤：
S21、电子设备接收针对目标视频的弹幕开启指令。
本申请实施例中，电子设备可以接收其他设备(比如手柄)发送的接收针对目标视频的弹幕开启指令。其中，所述弹幕开启指令用于指示采用虚拟现实VR弹幕方式播放弹幕。
其中，在步骤S21之前，电子设备可以在VR虚拟空间上绘制了视频层并播放目标视频，用户通过佩戴便携设备(如VR眼镜)，可以观看在视频层上渲染的目标视频。
S22、电子设备响应于所述弹幕开启指令，输出弹幕层编辑页面。
其中，电子设备可以在VR虚拟空间上输出弹幕层编辑页面，用户可以在该弹幕层编辑页面上设置弹幕层绘制参数，该弹幕层绘制参数可以包括但不限于弹幕层的高度、弹幕层的半径以及弹幕层的弧度，这些弹幕层绘制参数均是可调节的，用户通过调节弹幕层绘制参数，可以实现个性化定制适合自己的弹幕形状。
S23、电子设备接收在所述弹幕层编辑页面输入的弹幕层绘制参数。
S24、电子设备按照所述弹幕层绘制参数，在所述目标视频的视频层的预设方位绘制环形透明的弹幕层。
根据所述弹幕层绘制参数(高度、弧度以及半径)绘制出来的弹幕层，如图2A所示，弹幕层为环状结构，弹幕层在视频层的纵向和横向均有扩展区域，其中，预设方位比如视频层的上方，所述视频层的第一高度小于所述弹幕层的第二高度。整个弹幕层的区域面积大于视频层的区域面积。
S25、电子设备将所述弹幕层划分为新生弹幕区、主屏弹幕区以及历史弹幕区。
其中，每条新产生的弹幕会匀速跨越所述新生弹幕区、所述主屏弹幕区以及所述历史弹幕区。
S26、电子设备初始化所述新生弹幕区中的弹幕集。
本申请实施例中，在目标视频开始播放前，需要在整个新生弹幕区，初始化显示该新生弹幕区的弹幕集，这样才能保证在t＝0时刻，有弹幕从主屏弹幕区的主屏入口处入场，并在主屏弹幕区中显示。
请参见图2B，图2B是本申请实施例公开的一种弹幕在水平面上运动的坐标示意图。其中，v为弹幕运动速度，R为所述弹幕层的半径，α为所述主屏弹幕区的入口处与水平方向的夹角，β为弹幕产生的位置与水平方向的夹角，t为某一时刻。其中，α和β即弹幕绘制参数中的弧度，可以根据用户的要求进行调整。
每条弹幕从弹幕产生处开始运动，在目标视频开始播放前，初始化整个新生弹幕区中的弹幕集，在播放目标视频时，开始在新生弹幕区中显示实时弹幕i，实时弹幕i运动到主屏入口处，从主屏入口处进入主屏弹幕区，再运动到历史弹幕区，直至最后从弹幕消亡处消逝。
具体的，所述初始化所述新生弹幕区中的弹幕集包括：
计算初始化时间域；
获取处于所述初始化时间域内的所述新生弹幕区中的弹幕集；
计算所述弹幕集中的每条弹幕的初始化坐标；
按照所述初始化坐标，在所述新生弹幕区中显示所述弹幕集中的每条弹幕。
其中，所述初始化时间域为：[0，Δt 1]，其中，

所述初始化坐标为：
Figure PCTCN2021117205-appb-000022
其中，
Figure PCTCN2021117205-appb-000023
需要说明的是，在初始化阶段，整个新生弹幕区中显示的每条弹幕均是静态的，并没有运动，每条弹幕均按照初始化坐标显示在新生弹幕区中的固定位置。当初始化完成后，目标视频开始播放时，新生弹幕区中的弹幕开始实时运动，相应的位置坐标也会随之变化。
S27、电子设备判断所述新生弹幕区中的弹幕集是否被初始化完成，若所述新生弹幕区中的弹幕集被初始化完成，执行步骤S28，若所述新生弹幕区中的弹幕集未完成初始化，重复执行步骤S27。
本申请实施例中，所述新生弹幕区中的弹幕集需要被初始化完成之后，才能确保在t＝0时刻有弹幕从主屏入口处进入到主屏弹幕区中显示，如果初始化未完成，需要一直循环反复进行初始化，直至初始化完成。
S28、电子设备获取所述目标视频的实时弹幕的弹幕信息。
其中，所述弹幕信息可以包括，但不限于：弹幕内容、弹幕运动速度、实时播放时间、弹幕高度、弹幕原始位置以及弹幕高度。
S29、电子设备根据所述弹幕信息，计算所述实时弹幕在所述弹幕层上的三维坐标。

11)在所述实时播放时间，根据所述弹幕运动速度，计算所述实时弹幕在所述弹幕层的水平面上的水平坐标；
12)在所述实时播放时间，根据所述弹幕高度，计算所述实时弹幕在所述弹幕层的纵向面上的纵坐标。
其中，三维坐标指的是在实时播放时间t这一时刻，弹幕在VR虚拟空间的弹幕层上的三维坐标，包括水平面上的水平坐标以及纵向面上的纵坐标。

若所述实时播放时间处于所述第一时间域内，根据第一水平公式，计算所述实时弹幕在所述新生弹幕区内的第一水平坐标；或
若所述实时播放时间处于所述第二时间域内，根据第二水平公式，计算所述实时弹幕在所述主屏弹幕区内的第二水平坐标；或
若所述实时播放时间处于所述第三时间域内，根据第三水平公式，计算所述实时弹幕在所述历史弹幕区内的第三水平坐标。
其中，第一时间域即实时弹幕在新生弹幕区上运动的时间范围，第二时间域即实时弹幕在主屏弹幕区上运动的时间范围，第三时间域即实时弹幕在历史弹幕区上运动的时间范围。

为所述第一水平坐标或所述第二水平坐标或所述第 三水平坐标。
作为一种可选的实施方式，步骤12)中，所述在所述实时播放时间，根据所述弹幕高度，计算所述实时弹幕在所述弹幕层的纵向面上的纵坐标包括：
统计在所述实时播放时间内的实时弹幕的条数；
根据所述条数、每条所述实时弹幕的弹幕高度以及所述视频层的第一高度，计算第一间距；
根据所述条数、每条所述实时弹幕的弹幕高度以及所述弹幕层的第二高度，计算第二间距，其中，所述第二高度大于或等于所述第一高度；
若预设间距小于或等于所述第一间距，根据第一纵向公式，计算所述实时弹幕在所述弹幕层的纵向面上的第一纵坐标，其中，所述预设间距为预先设置的不影响所述目标视频的观看效果的相邻两条弹幕之间的最小间距；或
若所述预设间距大于或等于所述第一间距，且所述预设间距小于或等于所述第二间距，根据第二纵向公式，计算所述实时弹幕在所述弹幕层的纵向面上的第二纵坐标；或
若所述预设间距大于所述第二间距，根据第三纵向公式，计算所述实时弹幕在所述弹幕层的纵向面上的第三纵坐标。
为了更好的理解该可选的实施方式，请一并参见图2C，图2C是本申请实施例公开的一种同一时刻到达的弹幕在纵向上运动的坐标示意图。如图2C所示，以视频层的中心为坐标原点，绘制坐标系。其中，N为所述实时播放时间(即同一时刻)到达的实时弹幕的条数，h i为第i条所述实时弹幕的弹幕高度，H 0为视频层的高度(即第一高度)，H max为弹幕层的高度(即第二高度)，d为相邻两条所述实时弹幕的间距。同一时刻到达的弹幕稀疏时，间距d较大；同一时刻到达的弹幕弹幕密集时，间距d较小。
可以预先通过多次试验，设置一个预设间距d min，该d min为不影响所述目标视频的观看效果的相邻两条弹幕之间的最小间距，d min可以使用户获得弹幕+视频的最佳观看体验，使得弹幕之间的间隔不会过小导致密集，而影响视频内容的观看。
根据图2C中的各个参数，可以计算出视频层的区域所允许的相邻两条弹幕之间的最大间距(即第一间距)：
Figure PCTCN2021117205-appb-000034
同时，可以计算出弹幕层的区域所允许的相邻两条弹幕之间的最大间距(即第二间距)：
Figure PCTCN2021117205-appb-000035
根据该第一间距、第二间距以及预设间距之间的大小关系，可以将某一时刻到达的弹幕的数量划分为三种场景：稀疏弹幕场景、高峰弹幕场景以及超密集弹幕场景。
第一种场景：稀疏弹幕场景
如果
Figure PCTCN2021117205-appb-000036
表明视频层的高度足以在满足用户体验指标d min的前提下，覆盖这些弹幕，此时到达的弹幕较为稀疏。根据图2C中的各个参数，可以采用如下第一纵向公式计算第一纵坐标：
所述第一纵向公式为：
Figure PCTCN2021117205-appb-000037
其中，
Figure PCTCN2021117205-appb-000038
其中，最佳的弹幕纵向间隔可在区间
Figure PCTCN2021117205-appb-000039
内调整，在确定d后，即可计算出弹幕i相应的第一纵坐标z i。
在稀疏弹幕场景中，无需将弹幕分流到新扩展的弹幕层两侧，仅需将所有弹幕对齐视频层顶部，并向下纵向分布，如图2D所示，其中，中间的斜虚线范围即弹幕的实时覆盖范围。
第二种场景：高峰弹幕场景
在
Figure PCTCN2021117205-appb-000040
的情况下，同一时刻到达的弹幕较为密集。如果弹幕全分布在视频层，则过于密集，用户体验差，但是，如果弹幕层的高度足以满足用户体验指标d min，则将弹幕分流至弹幕层，可以降低密集度，提升用户体验。根据图2C中的各个参数，可以采用如下第二纵向公式计算第二纵坐标：
所述第二纵向公式为：
Figure PCTCN2021117205-appb-000041
其中，
Figure PCTCN2021117205-appb-000042
其中，最佳的弹幕纵向间隔可在区间
Figure PCTCN2021117205-appb-000043
内调整，在确定d后，即可计算出弹幕i相应的第二纵坐标z i。
在高峰弹幕场景，可将所有弹幕从屏幕的正中心，向垂直方向两侧分布，直到分布到垂直方向两侧的弹幕层，如图2E所示，其中，中间的斜虚线范围即弹幕的实时覆盖范围。
第三种场景：超密集弹幕场景
在
Figure PCTCN2021117205-appb-000044
的情况下，同一时刻到达的弹幕非常密集，以至于分流到弹幕层时，弹幕层的高度仍无法将所有弹幕在纵向最大程度地分散开。根据图2C中的各个参数，可以采用如下第三纵向公式计算第三纵坐标：
所述第三纵向公式为：
Figure PCTCN2021117205-appb-000045
其中，
Figure PCTCN2021117205-appb-000046
其中，最佳的弹幕纵向间隔只能取弹幕层所能允许的最大间隔
Figure PCTCN2021117205-appb-000047
在超密集弹幕场景，只能将弹幕撑满整个弹幕层高度，而以牺牲弹幕之间间隔为代价，如图2F所示，其中，中间的斜虚线范围即弹幕的实时覆盖范围。
参见图2G，图2G是本申请实施例公开的一种环形弹幕层伸展后的弹幕分布示意图。如图2G所示，被边界包围的斜虚线范围即弹幕在各个区域(新生弹幕区、主屏弹幕区以及历史弹幕区)的实时覆盖范围。实时弹幕从新生弹幕区出现，然后移动到主屏弹幕区，再移动到历史弹幕区消逝。当同一时刻的弹幕的条数较稀疏时，则采用“稀疏弹幕对齐视频顶部”的方式进行分布；当同一时刻的弹幕的条数较密集时，则采用“高峰弹幕从屏幕中心向两侧扩展” 的方式进行分布。
作为一种可选的实施方式，在对实时弹幕进行纵向分流时，还可以进一步利用每条弹幕的点赞量、弹幕高度等特征进行分流。比如，点赞量越多并且高度越小的弹幕集中到屏幕垂直方向的中心，点赞量越低并且高度越大的弹幕分流到弹幕层两侧，这样可以实现价值较低的弹幕分流到两侧，价值较高的弹幕集中在视频层中心，从而可以实现用户体验的最优化。
S210、电子设备根据所述三维坐标，在所述弹幕层上刷新并播放所述实时弹幕。
在图2所描述的方法中，通过充分利用VR虚拟空间，在视频层的预设方位增加环形透明的弹幕层，使得弹幕层的区域面积大于视频层的区域面积，实现了弹幕在空间的纵向扩展分流以及横向扩展延伸，摆脱了电子设备的屏幕的限制，使得弹幕的比例大于或等于100％。此外，相比较于原有的弹幕区域，在纵向上扩展了新的弹幕区域，可用于实现高峰期弹幕的纵向分散，使得用户在体验高峰弹幕的同时，享受视频高能片段本身的内容，同时，弹幕层在横向上也扩展了新的弹幕区域，用户向右转头时，可以在新生弹幕区提前观看新产生的弹幕，让用户有期待感；用户向左转头时，可以在历史弹幕区回顾历史弹幕，让用户有怀旧感，从而不仅可以在纵向上分流弹幕，减少弹幕高峰压力，提高视频内容的观看效果，同时，还可以丰富弹幕的渲染形式，提高用户体验。
