Description

一种供用户上传 3D视频到视频网站的系统和方法 技术领域
本发明属于三维视频处理技术领域, 尤其涉及一种供用户上传 3D视频到视频网站的系统和方法。
背景技术
近年来, 随着三维视频的逐步兴起, 三维立体效果的显示技术成 为目前火热的技术之一。 在视频中实现的 3D效果就是利用双眼立体 视觉原理, 通过让双眼所看到的图像不同, 使用户从显示器上获得三 维空间影像的视觉效果, 从而产生身临其境的感觉。 目前, 比较成熟 的 3D技术包括以下三种:
1.色差式 3D技术(即: AnaglyPhic3D), 是指: 用两台摄像机以 不同视角拍摄的影像分别以两种不同的颜色印制在同一副画面中。色 差式 3D先由旋转的滤光轮分出光谱信息, 使用不同颜色的滤光片进 行画面滤光, 使得一个图片能产生出两幅图像, 人的每只眼睛都看见 不同的图像,这样的方法容易使画面边缘产生偏色, 需要配备最常见 的红蓝 3D眼镜。
2.偏光式 3D技术(即: Polarization3D),是指:利用光线有 "振 动方向" 的原理来分解原始图像的,先通过把图像分为垂直向偏振光 和水平向偏振光两组画面, 然后 3D眼镜左右分别采用不同偏振方向 的偏光镜片, 这样人的左右眼就能接收两组画面, 再经过大脑合成立 体影像, 配合使用的是被动式偏光眼镜。
3.主动快门式 3D技术 (是指: ActiveShutter3D), 是指: 根据 人的双眼对影像频率的捕捉敏感度来实现的,通过提高画面的刷新率 (至少 120Hz) , 为左眼和右眼分别输出 60Hz快速刷新的图像, 这样 会在人的大脑实现立体的视觉感受, 配合使用的是主动快门式 3D眼 镜。 目前,三维视频显示技术在电视机等传统设备上的应用比较广泛, 对于视频网站来讲,现有的一些 3D视频网站仅实现了简单的 3D技术, 为用户提供色差式 3D视频的 3D效果, 其观看体验并不十分理想。此 夕卜,具有用户上传通道的视频网站也仅支持用户上传预先处理好的色 差式 3D视频, 用户无法上传独立两路的上下式 3D视频和左右式 3D 视频, 很难满足用户对 3D视频的大量需求。

附图说明
图 1 是本发明所述供用户上传 3D视频到视频网站的系统模块图; 图 2是本发明所述供用户上传 3D视频到视频网站的方法的流程 图。 具体实 ¾¾T式
为使本发明的上述目的、特征和优点更加明显易懂, 下面结合附 图和具体实施方式对本发明作进一步详细的说明。
图 1 是本发明所述供用户上传 3D视频到视频网站的系统模块图; 如图 1所示, 本发明所述在视频网站对 3D视频进行处理的系统共有 五大模块:
用户上传平台 1, 用于上传视频并对视频进行分类标识; 主要的 3D播放格式有上下式和左右式两种。 左右式 3D视频为左右分屏的播 放状态, 两边同时播放同样的内容, 但二者存在差异, 通过这些差异 来产生视频交错, 使得用户产生 3D感觉; 上下式 3D视频原理和左右 式相似, 也是非标准的长宽比的视频格式, 上下格式是上下排放的, 二者区别在于如果是上下格式, 分辨率算法是: 播放成 3D效果时, 视频分电影的画面长度不变,宽度是原来的 1/2,而如果是左右格式, 播放成 3D效果时, 电影的画面宽度不变, 长度是原来的 1/2。
分类方法有如下两种:
( 1 ) 标签: 设置视频标签, 主要为了标识 3D视频, 3D视频格 式为上下式或左右式。
( 2 )类别: 通过复选下框设置视频类别, 在为 3D视频的同时还 可分类其它视频类别; 通过单选框设置 3D视频格式, 3D视频不同于 普通视频, 视频格式又可再细分为上下式和左右式。
网站视频处理后台 2, 用于后台对视频进行 3D审核及 3D视频转 码操作;
后台 3D视频审核采用两种模式:
( 1 ) 默认审核 3D通过: 3D视频审核不经过后台管理人员的审 核, 相信上传者已对视频做了相应的 3D视频分类或打标签操作, 默 认 3D审核通过, 直接对 3D视频进行转码。
( 2 ) 后台审核用户上传 3D视频: a.用户已为视频打过标签或设置了视频类别:后台审核人员可以 根据用户设置的标签或者类别判断 3D视频的格式, 确认用户视频的 3D属性是否正确。
b.用户未给视频打过标签或设置了视频类别:后台审核人员需要 首先判断上传视频是否为 3D视频,再判断 3D视频格式为上下式还是 左右式, 并为该视频作后台统一标识。
后台视频转码操作过程如下:
相对于普通视频, 后台在实现 3D视频转码时需要做如下 3方面 的补充:
( 1 ) 提高码率: 3D视频格式分为上下式和左右式, 这两种格式 的视频采用一定的分辨率算法, 使视频尺才有了一定改变。 以 480P 的上下式 3D视频为例:分视频的画面长度不变,宽度是原来的 1/2, 上方和下方的分视频只占到了 480P的一半,因此在合成为最终 3D视 频时的清晰度会受到一定影响, 为了得到转码后较清晰的 3D视频效 果, 可以适当提高码率。
(2 ) 添加 3D logo :为了使 3D视频在播放时有统一的标识, 转 码后加上 3D的 logo。 添加 logo时, 利用 3D视频合成的原理, 使上 下式和左右式 3D视频的两个分视频的 logo在位置上有轻微差异,最 后出来 logo的就是 3D效果。
(3 ) 添加 3D字幕: 如果用户上传的 3D视频配有字幕, 可以对 字幕进行 3D处理, 使得字幕看起来也有 3D的效果。 添加 3D字幕的 原理和添加 3Dlogo—致。
中间层 3, 用于给 3D视频添加 3D属性标签; 在用户上传 3D视 频后, 为 3D视频添加一些 3D属性标签, 左右式的 3D视频添加标签 "VC , 上下式的 3D视频添加标签 服务器将 3D视频与 3D属性关 联在一起。 添加 3D标签的作用在于区分该视频是属于普通视频, 还 是属于 3D视频。如果不给 3D视频添加 3D标签, 则该 3D视频将被当 做普通视频播。 所以添加 3D标签是必不可少的环节。
网站前端 4, 用于返回视频元信息, 为网站用户和前端播放器提 供 3D视频相关信息, 例如视频地址, 上传时间和 3D信息等;
首先播放器访问视频服务器接口, 如果接口返回的数据中包含
3D标签, 则端播放器判断该视频为 3D视频, 并且对该 3D视频做进 一步的处理。
前端播放器 5,用于对已标识为 3D的视频进行 3D视频播放处理, 形成最终网站上供用户观看的 3D视频。 具体过程包括如下步骤:
51 , 播放器加载原始视频, 并利用元信息判断原始视频的 3D格 式;
52 , 根据不同的 3D格式分别进行色差处理、 偏光处理、 快门处 理;
53, 对经过色差处理、 偏光处理、 快门处理的上方视频和下方视 频进行合成;
54, 对经过色差处理、 偏光处理、 快门处理的左方视频和右方视 频进行合成;
55, 将上下方合成的视频与左右方合成的视频再次进行合成;
56, 对合成后的视频尺寸进行拉伸处理;
57, 经过上述的处理过程, 得到一张 3D图片, 再通过不断重绘 后续图片, 最终形成动态 3D视频。
图 2是本发明所述供用户上传 3D视频到视频网站的方法的流程 图。 如图 2所示, 本发明所述供用户上传 3D视频到视频网站的方法 主要包括如下步骤:
1.用户上传 3D视频,并做视频信息设置。
主要的 3D播放格式有上下式和左右式两种。 左右式 3D视频为 左右分屏的播放状态, 两边同时播放同样的内容, 但二者存在差异, 通过这些差异来产生视频交错, 使得用户产生 3D感觉; 上下式 3D视 频原理和左右式相似, 也是非标准的长宽比的视频格式, 上下格式是 上下排放的, 二者区别在于如果是上下格式, 分辨率算法是: 播放成
3D效果时, 视频分电影的画面长度不变, 宽度是原来的 1/2, 而如果 是左右格式, 播放成 3D效果时, 电影的画面宽度不变, 长度是原来 的 1/2。
分类方法有如下两种:
( 1 ) 标签: 设置视频标签, 主要为了标识 3D视频, 3D视频格 式为上下式或左右式。
( 2 )类别: 通过复选下框设置视频类别, 在为 3D视频的同时还 可分类其它视频类别; 通过单选框设置 3D视频格式, 3D视频不同于 普通视频, 视频格式又可再细分为上下式和左右式。
通过服务器, 将视频与设置好的 3D视频信息关联在一起。
2.后台 3D审核
后台对用户上传的 3D视频进行审核, 内容如下:
后台 3D视频审核采用两种模式:
( 1 ) 默认审核 3D通过: 3D视频审核不经过后台管理人员的审 核, 相信上传者已对视频做了相应的 3D视频分类或打标签操作, 默 认 3D审核通过, 直接对 3D视频进行转码。
( 2 ) 后台审核用户上传 3D视频:
a.用户已为视频打过标签或设置了视频类别:后台审核人员可以 根据用户设置的标签或者类别判断 3D视频的格式, 确认用户视频的 3D属性是否正确。
b.用户未给视频打过标签或设置了视频类别:后台审核人员需要 首先判断上传视频是否为 3D视频,再判断 3D视频格式为上下式还是 左右式, 并为该视频作后台统一标识。
3.后台视频转码
视频转码是指将已经压缩编码的视频码流转换成另一个视频码 流,以适应不同的网络带宽、不同的终端处理能力和不同的用户需求。 相对于普通视频, 后台在实现 3D视频转码时需要做如下 3方面的补 充:
( 1 ) 提高码率: 3D视频格式分为上下式和左右式, 这两种格式 的视频采用一定的分辨率算法, 使视频尺才有了一定改变。 以 480P 的上下式 3D视频为例:分视频的画面长度不变,宽度是原来的 1/2, 上方和下方的分视频只占到了 480P的一半,因此在合成为最终 3D视 频时的清晰度会受到一定影响, 为了得到转码后较清晰的 3D视频效 果, 可以适当提高码率。
(2 ) 添加 3D logo :为了使 3D视频在播放时有统一的标识, 转 码后加上 3D的 logo。 添加 logo时, 利用 3D视频合成的原理, 使上 下式和左右式 3D视频的两个分视频的 logo在位置上有轻微差异,最 后出来 logo的就是 3D效果。
(3 ) 添加 3D字幕: 如果用户上传的 3D视频配有字幕, 可以对 字幕进行 3D处理, 使得字幕看起来也有 3D的效果。 添加 3D字幕的 原理和添加 3Dlogo—致。
4.中间层添加 3D属性标签
在用户上传 3D视频后, 为 3D视频添加一些 3D属性标签, 左右 式的 3D视频添加标签 上下式的 3D视频添加标签 前端播放 器通过访问视频服务器接口, 在返回的数据中包含 3D标签, 使得前 端播放器可以根据这些 3D属性判断哪些视频为 3D视频,并且对标为 3D的视频做进一步的处理。
5.前端播放器处理
前端播放器处理 3D视频。 对于用户上传的上下式或左右式的 3D 视频, 分上方和下方, 左方和右方分别进行 3D格式的判断, 之后再 将上方和下方及左方和右方的视频合成一个 3D视频, 具体来说, 先 设定合成视频的尺寸, 根据选择的处理方法, 分别对上下的视频进行 相应的图片级处理, 之后再将处理好的两张图片叠加在一起, 渲染成
3D 画面, 由于处理过程中可能会使视频的尺寸发生变化, 处理后对 视频进行尺寸拉伸, 形成最终的 3D视频。
具体实施例:
1.用户上传 3D视频后, 后台在内容审核后进行 3D审核。若上传 时用户没有为视频做分类, 也没有为视频打标签, 直接上传, 后台 3D 审核时由于未发现该视频的分类或标签, 首先需要判断该视频的 种类。 经判断确定视频为 3D视频, 并进一步判断该视频为左右式 3D 视频, 为视频作了统一标记后进行视频转码。
2. 用户上传 3D视频后, 后台做基本审核后进行 3D审核。若上 传时用户为视频作了 3D视频的分类, 并选择了左右式 3D格式。后台 3D审核时发现该视频的分类为左右式 3D视频, 直接为视频作了统一 标记后进行视频转码。
3.对于网站视频库内的 3D视频, 可跳过系统用户上传一步, 经 后台审核后直接为视频作 3D视频标记后并进行视频转码, 由中间层 后交给前端及播放器处理。
本发明为用户提供了上传各类经处理的 3D视频和 3D原始视频的 平台, 实现了 3D视频资源的广泛交互。在后台对用户上传的 3D视频 和网站视频库内的 3D视频做统一的视频处理,使网站内的所有 3D视 频有规范的标识和良好的质量。 在前端播放器对 3D视频做进一步处 理, 使最终在网站上提供给用户效果良好的 3D视频。 最后应当说明的是:以上实施例仅用以说明本发明的技术方案而 非对其限制; 尽管参照较佳实施例对本发明进行了详细的说明, 所属 领域的普通技术人员应当理解:依然可以对本发明的具体实施方式进 行修改或者对部分技术特征进行等同替换;而不脱离本发明技术方案 的精神, 其均应涵盖在本发明请求保护的技术方案范围当中。
