图8示出了本申请一个示例性实施例提供的赛事直播的过程示意图，虚拟对象为本次比赛中的英雄角色，游戏服务器602包含比赛中所有英雄角色的行为数据和属性数据。直播开始后，图8中的推流服务器601将导播视角的赛事画面数据(包括虚拟场馆的画面数据和赛事现场画面数据)输入至UE模型，游戏服务器602源源不断地将赛事数据(所有英雄角色的行为数据和属性数据)输入至UE模型中。UE模型根据英雄角色的所处位置动态更新虚拟直播间中3D虚拟沙盘上的英雄头像位置。UE模型根据赛事画面数据(也即直播画面数据)更新虚拟放映厅中播放器容器呈现的画面。虚拟场馆是通过3D建模搭建的VR虚拟场馆。将合成的VR虚拟场馆的画面数据通过推送服务器601推送到观众客户端进行播放。推送服务器601发送的虚拟直播间的画面数据将通过N个CDN(Content Delivery Network，内容分发网络)厂商提供的CDN服务转发至M个客户端，N和M为正整数。
图9示出了本申请一个示例性实施例提供的赛事直播的方法流程图。
步骤701，比赛开始。
在比赛现场架设直播设备，进入正式的比赛直播，比赛队伍进入比赛状态，场地无关人员清空。
步骤702，游戏服务器处理赛事数据；现场摄像机录制现场直播画面。
直播设备包括导播摄像机，导播摄像机开始采集面向网络用户的画面，也即采用参赛选手比赛时的画面。
在对局过程中，参赛选手操控的游戏角色的赛事数据传递到游戏服务器中。赛事数据包括游戏角色的所在位置、经济信息、出装信息、技能使用情况、是否处于生存状态、选手视角下的游戏画面等等。
步骤703，将赛事数据、选手比赛现场视频和3D虚拟场馆的数据输入到虚幻引擎。
游戏服务器处理得到的赛事数据、现场摄像机录制得到的选手比赛现场视频和3D虚拟场馆的数据被输入到UE中。也即比赛开始后，现场画面会被导播摄像机拍摄下来，实时传送到UE中；赛事数据被游戏服务器加工处理后，也输入到UE中。还获取3D虚拟场馆的数据，将其输入到UE中。
UE将实时画面填充到3D虚拟场馆的播放器容器中，将赛事数据展示到赛事数据看板中，将英雄人物的位置移动路径输入到3D沙盘中，让3D虚拟场馆和赛事直播现场联动起来，用户可以在沉浸环境中观看更逼真维度的赛事。
可以根据产品要求，设计沙盘的3D模型，包括纹理、静态网格体、骨骼动画、以及坐标等，然后打包成沙盘模型文件。
开发人员将沙盘模型导入到虚拟场馆的UE模型工程中。开发人员编写蓝图脚本代码，这些代码将用来处理从外部输入进来的赛事数据，例如位置坐标数据、生命值数据等。还会设计展示角色生命值的生命条、头像纹理等。蓝图脚本代码根据实时的赛事数据，动态更新角色在三维虚拟沙盘中的位置，这种刷新频率在约10次/秒，还原出角色在比赛的移动情况。
步骤704，渲染合成VR视频流，向客户端推流。
在UE的三维虚拟场馆(包括虚拟电竞场馆)中，添加了一个第三人称视角的虚拟摄像头，这个虚拟摄像头会采集全场的所有的模型数据，渲染合成VR视频流，并且通过“场外直播(off world live)”插件转换，编码为实时消息传输协议(Real Time Messaging Protocol， RTMP)视频流，然后通过网络设备接口(Network Device Interface，NDI)传输协议传输到推流服务器，客户端拿到直播的视频流地址后，请求服务器拉取视频流，客户端拉取到数据后，在本地进行解码，音视同步，然后再渲染到一个球面体上，用户观看这个球面体，并且调整角度和位置，就可以沉浸式观看比赛视频。
图10示出了本申请一个示例性实施例提供的赛事数据处理的示意图，比赛开始后，参赛选手操控的角色人物会生产一系列的赛事数据。采用红蓝来区分两个阵营。头像贴图是通过赛事数据传递过来的英雄id，然后找到对应的英雄图片网络地址，将图片下载完后，通过UE转换为材质球，UE在运行期间将材质球渲染到VR画面(3D虚拟沙盘)中。赛事数据包含了角色人物的位置坐标，通过一系列离散的坐标数据，最终可以形成一个完整的角色位置路径。UE根据蓝图脚本的设定，将角色在3D虚拟沙盘的位置根据赛事数据进行更新，当更新的频率足够快的时候，就可以形成连续的位置移动效果。角色在场上的死亡和胜利数据，也可以反应为头像的颜色。胜利则让UE渲染为加了金边的头像，死亡了则将头像变为灰色显示。
本申请实施例的比赛直播方法，利用VR虚拟渲染能力，将3D场景中融入现实场景画面，从而构成混合现实。既达到了现场观赛的沉浸式感受，又可以利用虚拟建模的发散性，创造更多虚拟对象，甚至将游戏人物深度复刻还原到虚拟场景中，让VR观赛者以更加立体形式看到英雄的走位、出装、攻击等活动。
