( 5 )、 控制设备设置或调整多个摄像设备的摄像区域， 以使多个会议区 域与多个摄像设备——对应。
( 6 )、 控制设备设置或调整多个摄像设备的摄像角度， 以使相邻摄像设 备的相邻摄像区域边界线相互平行， 并且使多个摄像设备的主光轴近似垂直 平分对应的会议区域的视野垂直平面。
( 7 )、 控制会议现场的其他辅助设备按照用户要求工作， 例如放置会议 区域的桌面的升降， 放置显示设备的载体的角度或高度调整， 会议现场灯光 亮度的调整等。 需要说明的是， 上述控制设备在不影响会议或远端显示的前提下， 可以 设置在会场的任意位置， 例如可以设置在某个会议区域的某个会议坐席或显 示设备的后方， 也可以设置在会场外的机房。 通过本发明实施例提供的远程呈现系统， 从根源上避免了多个摄像设备 的摄像区域出现重叠， 使得多个摄像设备釆集到的视频图像不需要进行而外 的剪裁、 拼接、 平移等处理， 即可显示在远端的多个显示设备上。 相对与现 有的远程呈现系统， 远端的多个显示设备分别显示对应的摄像设备釆集的会 议现场画面， 互不影响， 从而保证了远端显示的显示质量； 不需要限制与会 人员的活动范围， 从而增加了用户的体验度， 不需要釆用额外的图像剪裁拼 接设备， 从而降低了远程呈现系统的成本。 优选地， 相互平行的相邻摄像区域边界线的间距对应于远端相邻显示设 备的显示区域的间 巨。 在具体的实施过程中， 相互平行的相邻摄像区域边界线之间的区域为拍 才聂的死角区域， 该区域多个 4聂像设备无法拍 4聂到， 因此， 远端显示设备也无 法显示这些死角区域， 可以通过特定的剪裁和拼接设备处理该死角区域， 但 是， 这样又增加了系统的成本。 最佳的解决办法， 就是用远端多个显示设备 的显示区域之间的间隔区域 （例如显示器的边框） 来遮挡这些死角区域的显 示， 因此， 可以调整多个摄像设备的拍摄范围及拍摄角度， 使得相互平行的 过上述手段解决拍摄死角区域的显示问题， 有效地利用了远端显示设备的物 理特点屏蔽掉死角区域的显示， 从而增加了用户的体-险度。 优选地， 相互平行的相邻摄像区域边界线的间距可以等于远端相邻显示 设备的显示区域的间距。 在实施过程中， 为使得处于两地的与会人员感觉是面对面交流， 通常釆 用对角线尺寸不小于 60英寸的显示设备， 这样， 显示设备可以以 1 : 1的比 例显示远端图像画面。 在这种情况下， 将相邻摄像设备的摄像区域边界线之 间的间距调整为等于远端相邻显示设备的显示区域的间距， 可以适应这种等 比例显示的显示设备的尺寸特点。 优选地， 如果远端相邻显示设备的显示区域的间距为零或远端釆用一块 显示设备显示本地会议图像， 则相互平行的相邻摄像区域边界线的间距近似 为 0。 在实施过程中， 如果远端釆用的显示设备间距为零或远端釆用一块显示 设备显示本地会议图像， 无法利用显示设备的物理特点屏蔽死角区域， 则可 以调整多个摄像设备间距或摄像角度， 尽量减少相互平行的相邻摄像区域边 界线的间 巨， 使之近似为 0, 从而适应远端显示设备没有边^ I的特点。 优选地， 多个摄像设备的每个摄像设备对应一个会议区域。 每个会议区 域可以包括多排会议坐席， 每排会议坐席前设置会议桌。 在实施过程中， 在多个摄像设备的相邻摄像区域边界线相互平行的前提 下， 可以在每个摄像设备的摄像区域内 （即摄像区域的两个边界线内的扇形 区域内）设置会议区域， 在此会议区域内布置会议桌和会议座椅。 该实施例 还充分利用了无限景深的特点， 使得每个会议区域可以布置多排坐席。 会议 桌和会议座椅可以分排布置， 逐层增加坐席数量， 并且可以根据摄像机的景 深范围， 具体确定布置几排坐席。 如图 2所示， 在桌面 207对面放置专用会 议桌 212和 225 (分前后两排 )以及三组用户坐席，分别是左边的（ 216, 217 ) 与 ( 228, 229 ), 中间的 ( 218, 219 )、 ( 230, 231 , 232 ) 以及右边的 ( 220, 221 )、 ( 233 , 234 )。 所述专用桌面以近似弧形方式面对显示器。 将每个 4聂像 设备对应的会议区域布置成上述形式， 保证了所属区域的坐席不会超过相应 摄像设备的摄像区域， 并且显示在远端的会场画面更加突出与会重要人员， 从而提高用户的体验度。 优选地 ,每个会议区域的会议桌上还可以设置辅助显示器和 /或音频釆集 设备， 辅助显示器用于显示与会议相关的视频图像， 如图 2所示， 在专用会 议桌 212以及 225桌面上放置若千音频釆集设备 213 , 214, 226, 227„ 在专 用会议桌 212上放置三台液晶显示器 222、 223、 224, 以及在专用会议桌 225 上放置三台液晶显示器 235、 236、 237。 由于会议现场空间可能会很大， 如果只在会议现场某处或某几处设置音 频釆集设备， 其声音釆集效果可能达不到预期， 因此， 在与会人员的附近设 置音频釆集设备可以保证声音釆集效果。 在实施过程中， 可以在每排会议桌 上设置音频釆集设备， 也可以根据该排的坐席数量具体确定每排会议桌上具 体设置的音频釆集设备数量， 例如， 前排只有两个坐席， 则可以设置一个音 频釆集设备（如麦克风或麦克风阵列）， 后排有多个坐席， 则每两个坐席之间 设置一个音频釆集设备。 在具体的实施过程中， 与会人员除了通过上述多个显示器观看远端视频 之外， 可能还需要了解会议相关的影像资料（例如视频片段， 幻灯片等）， 这 种情况下， 可以通过诸如画中画的方式将与会议相关的影像资料显示在上述 多个显示器的某一个显示器上， 但是， 这样显示与会议相关的影像资料必然 遮挡一部分远端视频画面， 影响了用户的体验度， 因此， 较佳的解决方法是 在每个会议区域的会议桌上设置辅助显示器， 来显示辅助影像资料， 更优地， 也可以通过辅助显示器同步显示远端某个会议区域的视频， 当然， 所有辅助 显示器的显示也通过上述控制设备控制。 通过辅助显示器显示其他视频， 使 得本发明实施例提供的远程呈现系统功能更加丰富， 用户体验度更高。 综上所述， 上述图 2所示的实施例， 不仅使得本地与会人员感觉到现有 远程呈现系统所具有的远端会场人员就在自己对面， 具有真人大小、 听声辩 位效果外， 还使得会场内无论哪个位置的与会人员在会场走动时， 其在远端 三个显示器上的图像上看起来， 动作是协调一致的， 比如， 很自然地从左边 显示器 201右侧消失， 然后从中间显示器 202的左侧出现， 不会出现在左边 显示器 201上的身体部位的画面还没消失， 而中间显示器上 202的左侧就已 经出现了该部位或者分别位于显示器 201和 202上的两部分身体画面在人眼 感觉上显得扭曲变形， 拼接不自然。 从本实施例可以看到， 由于釆用了摄像区域边界线平行技术， 与会者人 员数量仅受到会议室物理空间和摄像机本身的景深范围限制。根据实际测算， 会议室深度可以达到 7〜9米。 根据本发明实施例， 还提供了一种摄像机组， 应用于远程呈现系统， 包括： 多个摄像设备， 其中， 所述多个摄像设备被布 置成使得相邻所述摄像设备的相邻摄像区域边界线相互平行。 根据本发明实施例， 还提供了一种摄像机组， 应用于远程呈现系统， 包 括： 多个摄像设备， 其中， 所述多个摄像设备被布置成使得相邻所述摄像设 备的相邻摄像区域的边界线相互平行。 通过本发明实施例提供的摄像机组， 从根源上避免了多个摄像设备的摄 像区域出现重叠， 使得多个显示设备分别显示对应的摄像设备釆集的会议现 场画面， 互不影响， 不会重复显示某个区域， 从而保证了显示的显示质量。 优选地， 相邻摄像区域边界线的间距对应于远端相邻显示设备的显示区 域的间 巨。 相互平行的相邻摄像区域边界线之间的区域为拍摄的死角区域， 该区域 多个 4聂像设备无法拍 4聂到， 远端显示设备也无法显示这些死角区域， 但是可 以通过多个显示设备的显示区域之间的间隔区域 （例如显示器的边框） 来遮 挡这些死角区域的显示。 因此， 可以通过调整多个摄像设备的拍摄范围及拍 摄角度， 使得相互平行的相邻摄像区域边界线的间距对应于远端相邻显示设 备的显示区域的间距。 通过上述手段解决拍摄死角区域的显示问题， 有效地 利用了远端显示设备的物理特点屏蔽掉死角区域的显示， 从而增加了用户的 体验度。 优选地， 多个摄像设备为 3个摄像设备。 使得摄像机组可以有效的应用 于远程呈现系统， 保证了拍 «_范围。 下面通过具体的实施例详细介绍本发明实施例提供的摄像机组。 图 3是根据本发明实施例的应用于远程呈现系统的摄像机组俯视图。 如 图 3所示，该摄像机组包括三个摄像头， 并且三个摄像头被布置成以下特点：
1、 相邻拍摄区域的边界线两两平行。 两条相互平行的边界线之间的区 域为拍 死角区域。
2、 相邻拍摄区域的边界线的平行间距对应于相邻显示设备的有效显示 区域的水平间 巨。 在具体的实施过程中， 如果显示器可以达到 1 : 1 的显示 效果， 则上述平行间距可以等于相邻显示设备的有效显示区域的水平间距。 从而利用显示设备的物理间距有效遮挡了拍摄死角区域。 如果釆用整块宽屏显示设备显示三个设备头拍摄的三个会议区域，此时， 无法利用显示设备的物理间距遮挡拍摄的死角， 则可以调整三个摄像头的空 间夹角及焦距， 在保证相邻拍摄区域的边界线两两平行的前提下， 使得上述 平行间 巨近似、为 0。 从以上的描述中， 可以看出， 本发明实施例提供的技术方案， 有效地解 决了现有远程呈现系统的相邻摄像机拍摄区域会出现重叠的问题， 无需限制 远程会议与会人员的行动， 也无需增加昂贵的图像剪裁拼接设备， 不仅节省 了成本， 而且使得会场内无论哪个位置的与会人员在会场走动时， 其在远端 三个显示器上的图像上看起来 , 动作是协调一致的，从而增加了用户体验度。 以上所述仅为本发明的优选实施例而已， 并不用于限制本发明， 对于本 领域的技术人员来说， 本发明可以有各种更改和变化。 凡在本发明的 ^"神和 原则之内， 所作的任何修改、 等同替换、 改进等， 均应包含在本发明的保护 范围之内。
