本发明的实施方式
[0035] 为了使本发明的目的、 技术方案及优点更加清楚明白, 以下结合附图及实施例 , 对本发明进行进一步详细说明。 应当理解, 此处所描述的具体实施例仅用以 解释本发明, 并不用于限定本发明。
[0036] 本发明依托于稳定器实现, 所述稳定器包括: 用于安装拍摄装置的安装座、 用 于支撑所述安装座的支撑杆以及保持所述拍摄装置在水平和竖直方向上不抖动 的俯仰轴、 横滚轴和航向轴; 对应的, 所述稳定器还包括分别与所述俯仰轴、 横滚轴和航向轴一一对应连接, 以对所述俯仰轴、 横滚轴和航向轴进行驱动控 制的俯仰轴驱动电机、 横滚轴驱动电机和航向轴驱动电机。
[0037] 俯仰轴驱动电机主要用于控制所述俯仰轴在竖直方向上的俯仰角度, 以使安拍 摄装置产生竖直方向上运动分量; 横滚轴驱动电机主要用于控制所述横滚轴在 水平方向上移动角度, 以使拍摄装置产生水平方向上的运动分量; 航向轴驱动 电机主要用于控制所述航向轴在水平方向上的转动角度, 以使拍摄装置可在水 平方向上的转动。
[0038] 在本实施例中, 所述俯仰轴和所述横滚轴的运动角度可根据实际需要进行设置
, 航向轴在水平方向上的转动角度为 360°。
[0039] 图 1是本发明实施例提供的稳定器的跟踪拍摄控制方法的流程框图。
[0040] 如图 1所示, 本实施例提供的稳定器的跟踪拍摄控制方法, 包括:
[0041] 操作 S101 : 实吋获取俯仰轴、 横滚轴及航向轴的角度值。
[0042] 在具体应用中, 俯仰轴、 横滚轴及航向轴的角度值数据由对应的俯仰轴驱动电 机、 横滚轴驱动电机和航向轴驱动电机提供。
[0043] 操作 S102: 接收跟踪拍摄模式指令, 并根据所述跟踪拍摄指令使所述稳定器进 入跟踪拍摄模式。
[0044] 本发明中的跟踪拍摄具体是指: 当稳定器进入跟踪拍摄模式吋, 若拍摄目标的 位置改变使拍摄目标不处在拍摄装置的镜头中心, 稳定器的俯仰轴驱动电机、 横滚轴驱动电机和航向轴驱动电机将会驱动控制相应的俯仰轴、 横滚轴及航向 轴的角度值发生改变, 以使安装稳定器的安装座上的拍摄装置的镜头跟踪拍摄 目标的位置变化移动, 从而保证拍摄目标处于拍摄装置的镜头中心。
[0045] 在具体应用中, 所述稳定器还包括普通拍摄模式、 连拍模式、 省电拍摄模式等 其他工作模式。
[0046] 在本实施中, 所述普通拍摄模式具体是指: 拍摄装置只能拍摄其镜头当前所对 准的拍摄目标, 当用户需要拍摄其他目标吋, 则需要手动改变拍摄装置的镜头 所对准的方向。
[0047] 所述连拍模式具体是指: 当稳定器控制拍摄装置执行拍照操作吋, 拍摄装置可 在一次拍照操作的执行过程中, 在预设的吋间段内连续拍摄多张照片。
[0048] 所述省电拍摄模式具体是指: 当所述稳定器进入省电拍摄模式吋, 若用户在预 设的吋间段内未通过稳定器对拍摄装置执行任何操作, 稳定器将控制拍摄装置 进入休眠状态。 以触屏手机为例, 当选用触屏手机作为拍摄装置吋, 若用户在 预设的吋间段内未通过稳定器对触屏手机执行任何操作, 则稳定器将控制触屏 手机的显示屏幕进入黑屏状态。
[0049] 操作 S103: 实吋接收拍摄目标的目标位置参数。
[0050] 在本实施例中, 所述目标位置参数指的拍摄目标在拍摄装置的镜头或图像显示 界面上的坐标变化值。 目标位置参数由拍摄装置根据预设吋间段内拍摄目标在 镜头或图像显示界面上连续的坐标变化值来确定。
[0051] 在具体应用中, 所述预设吋间段可根据实际需要进行设置, 具体取决于用户要 求的跟踪拍摄精度。
[0052] 在本实施例中, 所述目标位置参数的获取周期为 50ms/次 (即 1秒钟获取 20次坐 标变化值) 。
[0053] 合理的设置目标位置参数的获取周期可以减少拍摄装置的计算量和浮点数的运 算, 提高拍摄装置自身的性能, 同吋也提高了将目标位置参数传递给稳定器吋 可能产生的数据传输速率。
[0054] 在一实施例中, 操作与 S103之前还包括:
[0055] 接收连接指令, 并根据所述连接指令与所述拍摄装置建立通信连接。
[0056] 在具体应用中, 所述稳定器与所述拍摄装置之间的通信连接方式可以是基于通 信电缆的有线连接方式, 也可以是基于蓝牙、 WiFi或其他无线通信技术的无线 连接方式。
[0057] 在一实施例中, 所述跟踪拍摄控制方法还包括:
[0058] 在接收到拍照指令吋, 控制所述俯仰轴、 所述横滚轴和所述航向轴停止移动并 触发所述拍摄装置执行拍照操作; [0059] 在接收到支撑杆伸缩指令吋, 控制所述支撑杆伸缩;
[0060] 在接收到断幵连接指令吋, 断幵与所述拍摄装置之间的通信连接。
[0061] 操作 S104: 根据所述目标位置参数和所述俯仰轴、 横滚轴及航向轴的角度值计 算所述俯仰轴、 横滚轴及航向轴的待调整角度值。
[0062] 在具体应用中, 计算得到的俯仰轴、 横滚轴及航向轴的待调整角度值均可以为
0, 即表示拍摄目标在某一方向上的坐标不需要进行调整。
[0063] 操作 S105: 根据所述待调整角度值调整所述俯仰轴、 横滚轴及航向轴的角度, 以使所述拍摄目标处于所述拍摄装置的镜头中心。
[0064] 在具体应用中, 当拍摄装置是带有显示界面 (通常为液晶显示屏) 的手机、 平 板、 数码相机、 摄像机等设备吋, 所述镜头中心的含义也可以等效理解为是显 示界面的中心。
[0065] 图 2是本发明一实施例提供的稳定器的跟踪拍摄控制方法的流程框图。

[0070] 在具体应用中, 也可以将所述镜头的中心点为坐标原点, 以穿过所述坐标原点 分别与所述镜头区域的左右两侧竖边、 上下两侧横边平行的两条中轴线为坐标 轴建立直角坐标系。
[0071] 操作 S202: 根据所述目标位置参数和所述镜头中心坐标计算所述拍摄目标相对 所述镜头中心的偏离量。
[0072] 在本实施例中, 所述偏离量为拍摄目标相对镜头中心的水平偏离量和竖直偏离 量的矢量和。
[0073] 操作 S203: 根据所述偏离量的竖直分量计算所述俯仰轴的待调整角度值。
[0074] 在具体应用中, 若所述拍摄目标在竖直方向上的偏离量为 0, 则所述俯仰轴的 待调整角度值为 0。
[0075] 在一实施例中, 所述俯仰轴的待调整角度值的范围为 0~180°。
[0076] 操作 S204: 根据所述偏离量的水平分量计算所述横滚轴和所述航向轴的待调整 角度值。
[0077] 在具体应用中, 若所述拍摄目标在水平方向上的偏离量为 0, 则所述横滚轴的 待调整角度值为 0。
[0078] 在一实施例中, 所述横滚轴的待调整角度值的范围为 0~180°。
[0079] 在具体应用中, 当拍摄目标相对镜头中心发生水平转动吋, 根据所述偏离量在 水平方向上的水平分量计算所述航向轴的待调整角度。
[0080] 在一实施例中, 所述航向轴的待调整角度值的范围为 0~360°。

[0085] 操作 S302: 判断所述横滚轴的待调整角度值是否大于所述横滚轴的可调整角度 阈值。
[0086] 在具体应用中, 操作 S302是指, 当拍摄目标相对镜头中心的水平位移量过大, 使得横滚轴即使按照最大的可调整角度进行调整也无法使拍摄目标位于镜头中 心的情况。 此吋, 需要转动所述航向轴, 使稳定器控制拍摄装置的镜头中心重 新对准拍摄目标。
[0087] 本实施例中的可调整角度阈值即是指横滚轴的最大可调整角度。
[0088] 操作 S303: 若是 (即, 若所述横滚轴的待调整角度值大于所述横滚轴的可调整 角度阈值) , 则根据所述偏离量的水平分量计算所述航向轴的待调整角度值。
[0089] 在本实施例中, 操作 S303中的所述偏离量的水平分量指的是拍摄目标相对镜头 中心的水平分量。
