为使本发明的目的、 技术方案和优点更加清楚, 下面将结合附图对本发 明实施方式作进一步地详细描述。
实施例 1 参考图 2,图 2是本发明实施例 1提供的一种控制可视光源的方法实施例 的流程图; 该控制可视光源的方法包括:
S101 : 当第一终端和第二终端处于视频会议状态时, 该第一终端获取该 第二终端发送的控制信息;
S102: 该第一终端根据该控制信息控制本地转动平台上的第一可视光源 进行转动, 使该第一可视光源指示的目标和该第二终端对应的显示器显示的 目标一致。
本实施例中, 当第一终端和第二终端处于视频会议状态时, 第一终端接 收第二终端发送的控制信息, 根据该控制信息控制本地转动平台上的第一可 视光源进行转动, 使该第一可视光源指示的目标和第二终端对应的显示器显 示的目标一致, 从而实现了第二终端对第一终端本地的第一可视光源的控制, 消除了交流障碍, 提高了视频会议中与会者的用户体验度。 实施例 2
参考图 3 ,图 3是本发明实施例 2提供的一种控制可视光源的方法实施例 的流程图; 本实施例中, 以第一终端和第二终端处于视频会议状态为例进行 详细描述, 其中, 该第一终端作为视频会议中的本地终端, 该第二终端作为 视频会议中的远端终端。
该控制可视光源的方法包括:
S201 : 第一终端设置第一可视光源的初始指示位置, 使该初始指示位置 与摄像机镜头的中心位置重合。
此步骤中, 当第一终端开机后, 在启动本地的第一可视光源时, 首先进 行该第一可视光源的初始指示位置的设置, 使该初始指示位置与本地的摄像 机镜头的中心位置重合; 具体地, 通过该摄像机捕捉该第一可视光源的第一 指示位置, 判断该第一指示位置是否与该摄像机镜头的中心位置重合, 如果 否, 调整该第一可视光源的第一指示位置至该摄像机镜头的中心位置, 将调 整后的该第一可视光源的指示位置设置为初始指示位置。
本实施例中, 第一终端设置完第一可视光源的初始指示位置后, 该第一 终端根据本地摄像机捕获的图像进行坐标映射, 此坐标为该第一终端后续控 制该第一可视光源的移动提供了依据。
坐标映射具体为: 以本地摄像机镜头的中心位置, 即第一可视光源的初 始指示位置为原点 (0,0 ) , 建立坐标系 (x,y ) ; 其中该第一可视光源所在转 动平台能够移动的最小移动步长设为 z,该第一可视光源从该图像的最左端水 平移动至中心位置需要以最小移动步长 z进行 n次, 该第一可视光源从该图 像的最上端水平移动至中心位置需要以最小移动步长 z进行 m次, 则坐标映 射示意图如图 4所示。
在视频会议中, 第一终端和第二终端互为对端。 该第二终端也需要根据 其对应的第二显示器显示的图像进行坐标映射, 其进行坐标映射的方法与该 第一终端进行坐标映射的方法类似, 在此不再赘述, 具体可参见上述描述。 其中该第二显示器显示的图像为该第一终端本地摄像机捕获的图像, 这样可 以使该第一终端和该第二终端坐标映射后得到的坐标保持一致性。
S202: 当第一终端和第二终端处于视频会议状态时, 该第二终端获取对 应的显示界面上的指示操作, 将所述指示操作解析为控制信息。
当第一终端和第二终端处于视频会议状态时, 远端与会者通过鼠标、 第 二可视光源或无线发射装置在第二显示器的显示界面上进行目标的指示操 作; 该第二终端获取该显示界面上的指示操作, 其中该指示操作包括停靠操 作和移动操作, 停靠操作是远端与会者将鼠标、 第二可视光源或无线发射装 置直接停靠在目标上的操作, 移动操作是远端与会者将鼠标、 第二可视光源 或无线发射装置移动至目标的操作。
该第二终端将该指示操作解析为控制信息; 具体地, 当该指示操作是停 靠操作时, 该第二终端根据停靠操作对应的位置进行坐标映射, 得到该第二 显示器显示的目标的坐标信息; 其中该坐标信息包括: 鼠标坐标信息、 第二 可视光源的指示坐标信息或无线发射装置的指示坐标信息。 当该指示操作是 移动操作时, 该第二终端根据移动操作对应的移动轨迹进行坐标映射, 得到 该第二显示器显示的目标的移动轨迹的信息, 其中该移动轨迹的信息包括: 鼠标移动轨迹的信息、 第二可视光源移动轨迹的信息或无线发射装置移动轨 迹的信息。
本实施例中, 该第二终端也可以通过本地摄像机捕捉到本地与会者的手 势, 在第二显示器的显示界面上对应生成一个类似鼠标的标识图, 将本地与 会者的手模拟为鼠标, 在移动的过程中, 手的作用与鼠标的作用类似, 在此 不再赘述。 相应的, 该坐标信息还可以包括手势指示坐标信息; 该移动轨迹 的信息还可以包括手势移动轨迹的信息。
本实施例中, 第二终端获取对应的显示界面上的指示操作还可以包括: 第二终端获取显示界面中目标区域的指示操作, 该目标区域为用户在该 显示界面中截取的区域;
具体地, 该第二终端在其对应的显示界面中截取需要进行精确目标指示 的目标区域, 将该目标区域显示于其他屏幕上, 或者, 将该目标区域通过第 二终端的另一窗口进行显示。 该第二终端通过鼠标或触摸屏的方式对该目标 区域进行目标的指示, 获取该目标区域所在界面的指示操作, 该指示操作包 括停靠操作和移动操作。 该第二终端还可以对该目标区域进行放大和 /或缩小 处理, 来得到更精确的指示目标。
该第二终端将该目标区域的指示操作解析为目标区域的控制信息; 该第 二终端将该目标区域的控制信息转换成该显示界面的控制信息。
实际应用中, 该第二终端将该目标区域的指示操作解析为目标区域的控 制信息的方法与第二终端将其对应的显示界面上的指示操作解析为控制信息 的方法类似, 在此不再赘述, 具体参照上述相关描述。 第二终端解析完目标 区域的控制信息后, 将该目标区域的控制信息进行坐标转换, 即将原图的子 图中的坐标转换为原图中的坐标, 得到第二显示器的显示界面的控制信息, 使得获取的指示目标更精确。
例如, 当第二显示器的显示界面中显示的是沙盘, 第二终端可以截取沙 盘上的一块区域作为目标区域进行放大处理后, 进行精确的目标指示, 解析 后再通过相应的坐标变换得到该显示界面中第二指示目标的坐标信息。
S203 : 该第二终端发送该控制信息至该第一终端。
此步骤中, 该第二终端发送该控制信息至该第一终端, 其中该控制信息 包括第二显示器显示的目标的坐标信息和第二显示器显示的目标的移动轨迹 的信息。
S204: 该第一终端接收该第二终端发送的控制信息。
S205: 该第一终端根据该控制信息控制本地转动平台上的第一可视光源 进行转动, 使该第一可视光源指示的目标和该第二终端对应的显示器显示的 目标一致。
此步骤中, 当该控制信息为第二终端对应的显示器显示的目标的坐标信 息, 即该控制信息为第二显示器显示的目标的坐标信息时, 该第一终端根据 该坐标信息, 将本地转动平台上的第一可视光源由第一位置转动至与该坐标 信息对应的位置, 使该第一可视光源指示的目标和所述第二显示器显示的目 标一致; 其中由该第一位置到该坐标信息对应的位置的距离大于该第一可视 光源所在转动平台的最小移动步长, 该第一位置可以为该初始指示位置。
例如, 当 m=10 , n=15 , z=l , 第一可视光源的第一位置为 (0,0 ) , 指示 目标的坐标信息为 (3,4 ) 时, 该第一终端将本地转动平台上的第一可视光源 由 (0,0 )移动至(3,4 ) 的位置, 使该第一可视光源指示的目标和该第二显示 器显示的目标一致; 其中 (0,0 )到 (3,4 ) 的距离为 5>1 , 满足该第一可视光 源所在转动平台的转动要求。本实施例对该第一可视光源从( 0,0 )移动至( 3,4 ) 的轨迹不作任何限定; 本实施例中该第一可视光源的第一位置也可以不是初 始指示位置 ( 0,0 ) 。
当该控制信息为第二显示器显示的目标的移动轨迹的信息时, 该第一终 端移动本地转动平台上的第一可视光源从第一位置至该移动轨迹的起点位 置, 其中从该第一位置至该移动轨迹的起点位置的距离大于该第一可视光源 所在转动平台的最小移动步长, 该第一位置可以为该初始指示位置; 该第一 终端控制该第一可视光源从该移动轨迹的起点位置起模拟该移动轨迹至该移 动轨迹的终点位置, 使该第一可视光源指示的目标和该第二显示器显示的目 标一致; 其中从移动轨迹的起点位置到终点位置的距离大于该第一可视光源 所在转动平台的最小移动步长。
例如, 当 m=10 , n=15 , z=l , 第一可视光源的第一位置为 (1,1 ) , 第二 显示器显示的目标的移动轨迹为从起点 (2,2 )移动至终点 (5,6 ) 时, 该第一 终端移动该第一可视光源从(1,1 )到 ( 2,2 ) , 其中从(1,1 )到 ( 2,2 ) 的距 离^ >1 , 满足第一可视光源所在转动平台的转动要求。 该第一终端控制该第 一可视光源从( 2,2 )起模拟该移动轨迹至终点( 5,6 ) ,其中,从( 2,2 )到( 5,6 ) 的距离 5>1 , 满足第一可视光源所在转动平台的转动要求。本实施例中该第一 可视光源的第一位置也可以是初始指示位置。
本实施例中, 该第一终端根据该控制信息控制本地转动平台上的第一可 视光源进行转动, 使该第一可视光源指示的目标和该第二显示器显示的目标 一致具体包括:
第一终端根据该控制信息控制本地转动平台上的第一可视光源进行转 动;

该第一终端判断该第一可视光源指示的目标是否与该第二显示器显示的 目标一致, 如果否, 对该第一可视光源进行校正, 使该第一可视光源指示的 目标和该第二显示器显示的目标一致。
此步骤中, 当该第一终端根据该控制信息控制本地转动平台上的第一可 视光源进行转动后, 还需要对该第一可视光源的指示位置进行校正, 使该第 一可视光源的指示位置更加精确。
当该控制信息是第二显示器显示的目标的移动轨迹的信息时, 需要按照 上述校正的方法对该移动轨迹中的各个点进行实时校正, 以保证该第一可视 光源模拟该移动轨迹的准确性。
可选的, 本实施例中该第一终端还可以在该第一可视光源移动的过程中 为: 打开该第一可视光源后, 在第一终端设置该第一可视光源的初始指示位 置之前, 本地摄像机进行本地与会者人脸的识别, 确定本地所有与会者眼睛 所在的多个预设区域; 第一终端获取并预先记录本地摄像机捕捉到的所有与 会者眼睛所在的多个预设区域, 并对所有与会者的眼睛所在的多个预设区域 进行定时刷新。 可选的, 本实施例所述方法还包括:

其中, 多个预设区域内的任一区域可按照下述方法来设定, 具体为: 以 本地与会者的人脸为模型, 以脸颊为左右界线, 以眉毛和颧骨为上下界线, 设定该预设区域; 但是并不局限于此, 只要设定的预设区域能保证本地所有 与会者眼睛不被可视光源直射, 就都在本发明实施例的保护范围之内, 在此 不再赘述。
可选的, 该第二终端根据摄像机捕捉的本地与会者的手势, 开启或关闭 第一可视光源。
具体地, 该第二终端可以将摄像机捕捉到的本地与会者的手势进行解析, 得到手势控制指令信息, 其中所述手势控制指令信息包括开启第一可视光源 的信息或关闭第一可视光源的信息; 所述手势控制指令信息与所述手势一一 对应;
例如, 摄像机捕捉到的与会者的手势为 "OK" 手势, 第二终端将 "OK" 手势解析为开启第一可视光源的信息, 将该开启第一可视光源的信息发送至 第一终端, 该第一终端根据所该开启第一可视光源的信息开启第一可视光源。
上述实施例都是以视频会议的每端只具有一个可视光源进行的描述, 但 是本实施例并不局限于此。 本实施例还可以控制多个可视光源进行目标指示, 具体地, 可以通过对多个可视光源进行编号, 分别进行控制; 或者通过在触 摸屏上进行多点触碰来实现多个可视光源的控制, 但是对多个可视光源中的 每个可视光源进行控制的方法与上述实施例描述的方法类似, 在此不再赘述, 具体可参见上述实施例的描述。
本实施例中, 当第一终端和第二终端处于视频会议状态时, 第一终端接 收第二终端发送的控制信息, 根据该控制信息控制本地转动平台上的第一可 视光源进行转动, 使该第一可视光源指示的目标和第二终端对应的显示器显 示的目标一致, 从而实现了第二终端对第一终端本地的第一可视光源的控制, 消除了交流障碍, 提高了视频会议中与会者的用户体验度。
