本发明实施例的图像处理系统包括上述用户终端和上述图像处理终 端。
本发明实施例的数据资源的来源不限于固定的用户 , 可以由各个自由 用户主动提供数据资源， 不限于 3D应用场景， 涵盖图像处理的各个场景， 这里为了描述方便， 以下以 3D应用场景为例进行描述。
3D应用场景下， 现有技术中， 为了得到 3D资源， 需要资源制作方如 电视台等， 事先调整好摄像机的参数、 摄像机的位置等， 也就是说， 目前 制作 3D 图像资源时需要在被拍摄对象周围按照一定的要求放置一定数量 的摄像机， 摄像机参数等在拍摄前已经被记录在案， 摄像机所处的位置根 据视点需要放置在不同角度、 高度等位置， 得到数据资源 （数据资源为多 媒体数据资源， 包括图像和视频资源）后， 对数据资源进行处理， 资源制 作方根据来自不同位置的数据及其相应的摄像机参数合成不同视点的 3D 视图， 最终通过节目呈现给用户。 在整个图像处理过程的核心是： 如何得 到数据资源， 而现有技术由于是固定用户， 固定的位置及事前准备所花费 的大量时间和成本。
本发明实施例在 3D应用场景下，为了避免固定用户对被拍摄对象进行 采集， 这种固定的位置及事前准备所花费的大量时间和成本， 提出了自由 用户也可以对被拍摄对象进行采集， 由于是自由用户， 因此无需事前对摄 像机位置进行设定， 对摄像机参数进行预先设定， 能节约大量时间和成本， 而且， 由于数据资源是自由用户提供的， 因此， 图像处理是一种自由视点 合成业务方案， 即通过当前大量的带有相关传感器的终端设备， 在其所摄 图像中携带有相关的采集参数（包括摄像机参数信息、 位置信息等）， 并且 将相关图像资源交给焦点设备处理， 焦点设备根据一个坐标体系， 将所得 的图像资源信息判断并分组， 根据检测结果将这些信息进行视点合成， 形 成不同视点的数据，最后整合成多个视点的 3D数据，可以让不同用户使用。 本方案的最大特色就是数据的来源是自由的， 即对于同一个场景有很多用 户用自己的终端设备在不同角度获取的图像可以通过本业务将这些图像数 据进行视点合成， 得到不同角度的数据更加真实， 因此称之为自由视点合 成业务方案。
综上所述， 本发明实施例针对 3D应用场景， 是一种多媒体 3D多视点 合成的业务方案， 包括: 1 )各个自由用户将设备上的图像或视频资源发送 到焦点设备上， 焦点设备可以是某个性能较高的终端设备， 也可以是一个 服务器设备； 2 )焦点设备根据所设置的坐标评价体系， 将所获得的图像或 者视频资源进行分组处理， 判断出最优图像 (所谓最优不仅包括了拍摄的 图像质量，还包括拍摄的角度等），选取不同视点的最优图像进行视点合成， 形成不同视点的图像或者视频数据， 再把该合成后的数据提供给各个用户。
与现有技术相比， 应用本发明实施例， 针对 3D应用场景的优越性， 主 要体现在以下几个方面：
1、 不需要事先设定好各个设备的位置；
2、 允许用户定义相关参数和合成参数设置；
3、 充分利用了用户设备的能力。
方案一： 3D应用场景下的一个实现方案： 该方案为利用自由用户提供 的数据资源获得视点合成 3D图像或者 3D视频数据，该方案中包括用户 1 , 用户 2, ......用户 N, 用户 1 , 用户 2, ......用户 N所使用的设备作为各个 终端设备， 用于采集数据资源， 焦点设备用于对各个终端设备所采集汇总 的数据资源进行多视点合成的图像处理， 如图 4所示， 包括以下步驟： 步骤 301 : 各个用户通过各自的设备拍摄相应的物体，得到对应的图像 或视频资源， 该资源中需要携带摄像机参数和位置参数等， 之后， 焦点设 备提供和用户交互的信息， 如可以通过网络链接进行交换， 并提供相应的 存储空间， 各个用户 （用户 1 , 用户 2, ......用户 N )将数据资源上报焦点 设备处理。
这里， 数据资源包括： 所摄的图像或视频资源等多媒体数据资源； 上 报数据资源时， 也可以同时携带用户摄像机的参数信息、 位置信息等。
步驟 302: 焦点设备针对上报的数据资源进行视点合成的图像处理。 这里， 步骤 302包括： 1 )焦点设备设置选定参考坐标和参考资源， 设 定参数信息； 2 )焦点设备通过所设定的参数信息和所获得的图像或视频资 源， 根据资源中的参数信息和焦点设备中设定的参数信息进行比对判定， 对资源进行分组， 并对资源进行优化选择; 3 ) 分拣图像并分组根据条件做 视点合成图像处理， 即焦点设备通过对数据的优化选择， 焦点设备对分组 数据进行各个视点的数据合成， 形成不同的视点数据集合。
步骤 303: 焦点设备将视点合成得到的 3D数据存储， 并生成相应的信 息， 提供给用户。
本方案在自由视点合成中， 用户通过网络将所摄对象的图像或视频资 源提供给焦点设备， 焦点设备根据所设条件区分所获得的数据资源， 分拣 挑选合适数据资源进行视点合成， 形成不同视点的合成 3D数据， 最后提供 给用户使用。
方案二: 3D应用场景下的一个实现方案： 该方案为利用自由用户提供 的 3D数据资源获得视点合成 3D图像或者 3D视频数据后形成增强现实所 用的模版资源。
步骤 401 : 各个用户通过各自的设备拍摄相应的物体，得到对应的图像 或视频资源， 该资源中需要携带摄像机参数和位置参数等， 之后， 焦点设 备提供和用户交互的信息， 如可以通过网络链接进行交换， 并提供相应的 存储空间， 各个用户 （用户 1 , 用户 2, ......用户 N )将数据资源上报焦点 设备处理。
这里， 数据资源包括： 所摄的图像或视频资源， 用户摄像机的参数信 息、 位置信息等。
步骤 402: 焦点设备针对上报的数据资源进行视点合成的图像处理。 这里， 步骤 402包括： 1 )焦点设备设置选定参考坐标和参考资源， 设 定参数信息； 2 )焦点设备通过所设定的参数信息和所获得的图像或视频资 源 , 根据资源中的参数信息和焦点设备中设定的参数信息进行比对判定， 对资源进行分组， 并对资源进行优化选择; 3 ) 分拣图像并分组根据条件做 视点合成图像处理， 即焦点设备通过对数据的优化选择， 焦点设备对分组 数据进行各个视点的数据合成， 形成不同的视点数据集合。
步驟 403: 根据业务需要， 对视点合成数据进行再处理， 形成增强现实 业务的模板数据资源。
步骤 404: 焦点设备将视点合成数据存储并生成相应的信息，提供给用 户。 用户使用该模板数据资源可以享受增强现实业务所带来的方便。
针对模板数据资源而言， 举例来说， 在上述方案一中， 只是提供了一 个基本信息， 也可以说， 是将所有信息记录下来， 但是不能选择处理， 比 如拍摄得到一个欧冠赛场的信息， 包括球场和球员等等， 是不能进行选择 和后期修改的， 只能随着变化不断进行视点合成， 得到不同的结果， 而本 方案是提供一个模板数据资源， 可以对记录下来的信息进行选择处理， 可 以后期修改的， 比如拍摄得到一个欧冠赛场的信息， 包括球场和球员等等， 将这些信息作为一个模板资源， 如果在该球场换了球员进行比赛， 可以随 便更换数据， 以进行后期处理。
图 5-6为应用本发明实施例的数据格式的示意图，图像或者视频资源的 数据格式是在数据格式中增加相应的摄像机参数和对应该图像或视频资源 的拍摄位置参数。 摄像机参数由拍摄终端上的摄像头提供， 位置参数可以 由拍摄终端上的位置传感器设备获取， 如电子罗盘、 GPS 等设备可以提供 相应的位置参数。摄像机参数和位置参数除了如图 5-6所示, 还可以置于资 源的头数据区。
本发明实施例所述集成的模块如果以软件功能模块的形式实现并作为 独立的产品销售或使用时， 也可以存储在一个计算机可读取存储介质中。 基于这样的理解， 本发明实施例的技术方案本质上或者说对现有技术做出 贡献的部分可以以软件产品的形式体现出来 , 该计算机软件产品存储在一 个存储介质中， 包括若干指令用以使得一台计算机设备（可以是个人计算 机、 服务器、 或者网络设备等）执行本发明各个实施例所述方法的全部或 部分。 而前述的存储介质包括： U盘、 移动硬盘、 只读存储器 （ROM, Read-On ly Memory )、 随机存取存储器 ( RAM, Random Access Memory )、 磁碟或者光盘等各种可以存储程序代码的介质。 这样， 本发明实施例不限 制于任何特定的硬件和软件结合。
相应的， 本发明实施例还提供一种计算机存储介质， 其中存储有计算 机程序， 该计算机程序用于执行本发明实施例的终端小区切换中与 WLAN 互操作决策的方法。
以上所述， 仅为本发明的较佳实施例而已， 并非用于限定本发明的保 护范围。 工业实用性
本发明实施例的图像处理方法包括: 用户终端上报基于不同视点的采 集参数和多媒体数据资源； 所述用户终端为位置不固定的任意用户终端； 用户终端接收根据所述采集参数和所述多媒体数据资源得到的多视点合成 的图像处理结果。 采用本发明实施例， 由于所述用户终端为位置不固定的 任意用户终端， 则使用这类用户终端的用户可以称为自由用户， 由自由用 户所提供的数据资源无需事先调整好摄像机的参数、 摄像机的位置等， 从
而最终能快捷、 稳定地获得 3D资源， 而且无需高昂的制作成本。
