一并请参图1和图2，本申请实施方式提出的一种云台控制装置100，包括：握持部110，连接部120，传感器130和处理器140。握持部110通过连接部120可活动地连接于云台200的机架210。传感器130用于检测握持部110相对于机架210的转动动作，生成运动信息。处理器140用于根据运动信息控制云台200。其中，握持部110在转动的过程中通过连接部120向云台200的机架210提供支撑力。
上述云台控制装置100中，握持部110可以一定程度上提供把持力的支撑，能够让用户通过直观的位置控制来控制云台200，降低用户操作云台200的难度，提升云台200运动时的稳定性及一致性，可提升拍摄效果。
参照图3，具体地，本实施方式的云台控制装置100，可应用于各种拍摄场景中，其与云台200相配合使用，云台200用于放置固定手机或相机等拍摄装置220，该云台控制装置100可用于控制云台200。机架210可包括用于承载云台200的第一端和远离云台200的第二端，第一端和第二端之间形成有机架210的侧壁。握持部110通过连接部120连接于机架210的侧壁。机架210可以作为云台200的手柄或支架。
更具体地，握持部110通过连接部120可活动地连接于云台200的机架210，用户在使用云台200以及该云台控制装置100的时候，双手分别握持握持部110和机架210，其中，连接部120可以是设于机架210上的一个连接结构，或者是独立设置并且连接握持部110和机架210的连接结构，该连接结构的形状以及位置满足握持部110通过其向机架210提供支撑力的要求。在一个实施方式中，握持部110在转动的过程中通过连接部120向云台200的机架210提供转动轴向上的支撑力。如此，可以对云台200提供更稳定支撑。
连接部120可以固定连接或可拆卸地连接握持部110和机架210。固定连接的方式可以是焊接、两者一体成型所形成的一体结构连接。可拆卸地连接方式可以是螺纹连接、卡扣连接、磁吸连接、过盈配合连接等等。
传感器130可以作为位置传感器130，能够检测握持部110相对于机架210所发生的转动动作，其设置的位置以及具体的传感器130类型不作具体限定，以实现检测握持部110与机架210之间的相对转动动作为准。在一个实施方式中，传感器130可包括角度传感器，角度传感器能够检测握持部110相对于机架210所发生的转动动作。角度传感器可包括霍尔传 感器、旋转编码器、或其它角度传感器。
处理器140可以设置在机架210内，并能够处理各种的输入信号，这些输入信号包括传感器130检测到的运动信息，处理器140根据运动信息控制云台200做出相应操作，该操作包括但不限于控制云台200作沿各旋转轴的转动，从而实现变换拍摄装置220的拍摄角度的目的，以及云台200参数调整等等。
参照图1和图3，该云台控制装置100可以根据握持部110相对于机架210的转动动作来控制云台200运动以达到调节拍摄装置220姿态的有益效果。当拍摄装置220的拍摄角度需要调节的时候，用户可通过使握持部110与机架210发生相对的转动动作来实现，握持部110连接的传感器130可以识别出当前握持部110转动到的角度，生成运动信息，将连续的运动信息发送给处理器140，处理器140通过融合当前云台电机230的角度和握持部110的运动信息变化，控制云台电机230转动到相应的角度，达到变换拍摄装置220的拍摄角度的目的。云台电机230的角度可以通过姿态传感器获取。
进一步地，握持部110通过连接部120与云台200的机架210连接，用户的双手分别握持机架210和握持部110，从而能够同时给云台设备300提供两个支撑力，如此能够使得云台200在使用过程中更加平稳，尤其地，当拍摄装置220需要进行拍摄状态调节的时候，通过其中一只手控制握持部110的运动状态以及与机架210的相对位置关系而调节拍摄状态，另一只手同时给机架210提供支撑力，避免用户单手握持和操作相应功能组件时发生晃动，尤其是避免拍摄状态中需要移动云台200并同时操作相应功能组件的时候发生晃动，从而使得云台200保持平稳的状态，进而实现拍摄装置220在移动过程中以及变换拍摄角度的时候保持拍摄画面平稳的有益效果，最终提升拍摄装置220的拍摄效果。另外地，通过握持部110与机架210的相对转动来实现对云台200的控制，能够让用户可以通过直观的位置变化控制来达到控制云台200的目的，降低了用户操作云台200的难度。
在一个实施方式中，云台200或握持部110可以进入锁定状态。锁定状态可通过按键、触摸屏或语音指令触发或解除。在锁定状态下，握持部110可以运动，但是传感器130不再检测运动状态，或者检测到运动状态之后不向处理器140发送所检测到运动状态。这样，用户可以调整握持部110的姿态可以是为了更好的握持，此时握持部110仅具备提供支撑力的作用。解除锁定状态后，握持部110可以运动，传感器130可以检测运动状态，生成运动信息发送至处理器140，处理器140根据运动信息控制云台200。
在相关技术中，云台的手柄上往往有较为粗糙的花纹，增大摩擦力、吸汗、增加握持的牢固度。这意味着手掌面与云台手柄之间运动减少，处于静摩擦力。而当用户托举云台的姿 态发生变化，例如双手握持云台从身体左侧移动至身体右侧，相应的握持云台的姿态也会发生变化。一般云台使用过程中，尤其是拍摄过程中不便于松手以调节握持的手势，这样握持力会压迫手腕，长久处于不适当的握持姿势，用户容易疲劳。
在本申请实施方式中，云台控制装置100包括握持部110和连接部120。握持部110通过连接部120可活动地连接云台200机架210，使得握持部110可以相对于机架210转动，并同时提供支撑力，用户可以双手分别握持不同的云台200支撑部位，克服了单手握持手柄或双手同时握持同一手柄而不便于松手以调节握持的手势所导致的用户容易疲劳问题。
以云台200为三轴云台为例说明。三轴云台200包括操作部、航向轴组件(Yaw)、横滚轴组件(Roll)和俯仰轴组件(Pitch)。以拍摄装置220侧为云台200内侧，机架210侧为云台200外侧定义轴序，三轴云台200从内到外的轴序可以是：横滚轴组件、俯仰轴组件和航向轴组件。机架210连接航向轴组件，操作部设置在机架210上，航向轴组件可以驱动横滚轴组件、俯仰轴组件和拍摄装置220沿航向轴转动。
云台200的使用方式和使用姿态可以理解为，用户为达到所需的拍摄方式(例如拍摄装置220的镜头的推、拉、摇、移等)而将云台200进行诸如相应运动以为拍摄装置220提供各种的辅助，这种相应运动可以是云台200在水平方向上的位置的改变及云台200相对水平方向的倾斜角度的改变，也可以是云台200在竖直方式上的位置的改变及相对竖直方向的倾斜角度的改变。
在某些实施方式中，在握持部110转动时，连接部120限制握持部110在转动动作的转轴轴向上与机架210的相对位置关系。如此，能够使得握持部110在被转动的时候保持稳定，便于用户精准的通过握持部110的转动来实现预想的一个控制目的。
具体地，连接部120可具有限位结构，限位结构可限制握持部110与机架210的相对位置关系。在一个实施方式中，限位结构可开设有容置槽，容置槽可以容置握持部110沿转轴轴向上的一端，该握持部110沿转轴轴向上的一端可以卡在容置槽内，以防止握持部110转动过程中脱离连接部120，进而限制握持部110的转轴轴向上与机架210的相对位置关系，避免握持部110转动过程中发生期望外的位移而影响云台200的稳定性。
在某些实施方式中，握持部110包括内轴件和外周握持件，外周握持件套设于内轴件的外表面，并能够相对于内轴件转动，内轴件与连接部120固定连接。如此，可以实现握持部110转动和连接部120限制握持部110与机架210的相对位置关系。
具体地，在本实施方式中，相对于内轴件转动外周握持件时，可以理解为握持部110作自转运动。外周握持件位于握持部110的外周面，传感器130可以设置在连接部120上，用 户握持住握持部110的外周握持件，并可以转动外周握持件以使其围绕内轴件相对转动，传感器130能够检测外周握持件的转动动作，生成运动信息。可以理解，外周握持件作相对于内轴件转动能够更加便于用户通过手部感觉来控制云台200，这种操作方式产生的晃动更少，使得云台200的稳定性更好，从而提升了拍摄装置220的拍摄画面的平稳度和云台200的控制精度。
在某些实施方式中，处理器140用于根据运动信息控制云台200的电机230。如此，可以控制通过电机230来控制云台200姿态，进而控制拍摄装置220的姿态。
具体地，在一个实施方式中，云台200可以是三轴云台，三轴云台包括航向轴组件、横滚轴组件和俯仰轴组件。以拍摄装置220侧为云台200内侧，机架210侧为云台200外侧定义轴序，三轴云台从内到外的轴序可以是：横滚轴组件、俯仰轴组件和航向轴组件，也可以是俯仰轴组件、横滚轴组件和航向轴组件，也可以是横滚轴组件、航向轴组件和俯仰轴组件等等，在此不作具体限定。拍摄装置220安装在最内侧的轴组件上。处理器140根据运动信息控制云台200的电机230，可以是控制横滚轴组件的电机、俯仰轴组件的电机和航向轴组件的电机中的至少一个。当控制两个或两个以上电机230时，可以同时控制，或分时控制，根据预先设定的规则进行控制即可。航向轴、横滚轴和俯仰轴可以是三个轴相互之间是正交的，也可以三个轴相互之间是非正交的，也可以是其中两个轴相互正交，与另一轴非正交等等。
在一个实施方式中，云台200可以是两轴云台，两轴云台包括航向轴组件、横滚轴组件和俯仰轴组件中的其中两个。轴序的定义和电机230的控制可参上述三轴云台的说明，在此不作详细展开。
在一个实施方式中，云台200可以是单轴云台，单轴云台包括航向轴组件、横滚轴组件和俯仰轴组件中的其中一个。拍摄装置220安装在单轴云台的轴组件上。处理器140根据运动信息控制轴组件的电机230。

可以理解，在其它实施方式中，功能键还可以包括其它实体键，或虚拟键，虚拟键可以显示在触摸显示屏。触摸显示屏可以安装在机架210上。
在某些实施方式中，功能键包括用于控制云台200的电机230转动的电机230转向功能键；运动信息用于调整电机230转向功能键对应控制的电机230。如此，可以实现对应电机230的控制。

云台电机230可以是横滚轴电机、航向轴电机、俯仰轴电机、调平电机中的至少一个。通过握持部110的运动信息来控制电机230的转向，实现不同电机230转动方向的调整。
参照图3，在某些实施方式中，运动信息用于调整拍摄装置220的拍摄参数。如此，用户可以通过操作握持部110便可以调整拍摄装置220的拍摄参数，提升用户体验。
具体地，拍摄装置220的拍摄参数包括但不限于：对焦和/或变焦；光圈、快门速度、感光度值、白平衡等曝光参数；以及闪光灯的开关。运动信息与拍摄参数之间的对应关系的一些实施方式如下表所示：
  顺时针转动 逆时针转动 远离 靠近
焦距 长 短 长 短
感光度值 增加 减少 增加 减少
远离可以是指握持部110远离机架210移动，靠近可以是指握持部110靠近机架210移动。
具体地，握持部110的外周握持件可绕内轴件沿顺时针或者逆时针转动，拍摄装置220的焦距相应的拉长或者拉近。握持部110包括接近机架210的第一端和远离机架210的第二端，握持部110运动使得第二端远离机架210，拍摄装置220的焦距被拉长，握持部110运动时使第二端靠近机架210，拍摄装置220的焦距被拉近。感光度值也可以作类似操作来调整。
在某些实施方式中，握持部110还包括阻尼部，阻尼部用于调节握持部110的运动阻尼。如此，可以使用户在控制握持部110运动时感受到一定阻尼变化，提升用户体验。
具体地，阻尼部能够对握持部110运动产生阻力，阻力可以随着转动角度增大而增大，或增大而减少等，可以提示用户对云台200或拍摄装置220的控制达到一定的极限，提升用户体验。
在某些实施方式中，阻尼部被配置为，根据云台200的参数和/或拍摄装置220的参数调整运动阻尼。如此，能够使阻尼部根据云台200的参数变化和/或拍摄装置220的参数变化以及所需要设置的参数不同而进行调整，以适应实际需要和用户的预期。
具体地，阻尼部的阻尼大小随着云台200的参数大小不同或参数类型不同而发生改变，这些参数包括但不限于云台电机230的参数，云台200操作模式参数。例如，当通过握持部110的运动信息调整云台电机230的参数从小变大时，阻尼部对握持部110的运动阻尼从小变大，以提示用户，云台电机230的参数快调整到所需的数值，以利于用户及时收力，避免过调。
拍摄装置220的参数可以是拍摄参数和拍摄角度，拍摄参数包括但不限于：对焦和/或变焦；光圈、快门速度、感光度值、白平衡等曝光参数；以及闪光灯的开关，另外地，拍摄角度包括但不限于拍摄装置220的俯仰角度、航向角度、横滚角度等。
在某些实施方式中，运动信息用于控制云台200的目标参数；阻尼部被配置为，随着云台200或拍摄装置220的目标参数取值接近对应参数的取值范围的端值，增加运动阻尼。如此可以使得握持部110的控制灵敏度能够跟随云台200或拍摄装置220的目标参数改变而做出适应的调整，从而避免握持部110运动对与之对应的云台200参数或拍摄装置220参数的控制灵敏度过大或者过小。
具体地，在一个实施方式中，以云台200目标参数作为说明，在云台200的目标参数为第一参数值时，控制运动阻尼为第一阻尼值，在云台200目标参数为第二参数值时，控制运动阻尼为第二阻尼值，第二参数值较第一参数值更接近目标参数取值范围的端值，第二阻尼值大于第一阻尼值。其中，阻尼部可以设置档位变化阻尼，也可以无极调节阻尼。具体的一些实施方式如下表所示：
Figure PCTCN2022082314-appb-000001
在某些实施方式中，运动信息用于控制云台200的目标参数；云台200被配置为，基于接受到的用户指令调节运动信息与目标参数之间的对应关系。如此，使得用户能够通过握持部110所产生的运动信息对运动信息和云台200的目标参数的对应关系进行调整。
具体地，目标参数包括但不限于拍摄装置220的跟焦速度、电机230转向控制速度和变焦灵敏度等，运动信息与目标参数之间的对应关系包括但不限于以下的一些实施方式：握持部110沿左右方向被扳动以调节拍摄装置220的跟焦速度，握持沿前后方向被扳动以调节电机230转向控制速度，握持部110绕轴被转动以调变焦灵敏度。
用户指令可以是基于用户对云台200操作部的操作而产生的，或用户语音指令，或通过用户终端(如手机、平板电脑等)发送至云台200的，云台200能够基于用户指令对运动信息与目标参数之间的对应关系进行调节，例如，初始时，握持部110沿左右方向被扳动以调节拍摄装置220的跟焦速度，握持部110沿前后方向被扳动以调节电机230转向控制速度。基于用户指令，可以将握持部110沿左右方向被扳动以调节拍摄装置220的跟焦速度，调节为，调节电机230转向控制速度；握持部110沿前后方向被扳动以调节电机230转向控制速度，调节为，调节拍摄装置220的跟焦速度等。
在某些实施方式中，传感器130，用于接收用户指令暂停生成运动信息。如此，调整握持部110姿态是为了更好的握持，此时握持部110具备提供支撑力的作用，不具备控制云台200的作用。
具体地，在用户不需要通过操作握持部110来控制云台200的时候，传感器130暂停生成运动信息。云台200或握持部110可以进入锁定状态。锁定状态可通过用户指令触发或解除，用户指令可以由按键、触摸屏或语音指令来实现。当传感器130暂停生成运动信息的时候，此时可以理解为云台200或握持部110处于锁定状态，握持部110可以运动，但是传感器130不再检测运动状态，或者检测到运动状态之后不再向处理器140发送检测到的运动状态。这样，用户可以调整握持部110的姿态可以是为了更好的握持，此时握持部110仅具备提供支撑力的作用。解除锁定状态后，握持部110可以运动，传感器130可以检测运动状态，生成运动信息发送至处理器140，处理器140根据运动信息控制云台200。
本申请实施方式还提出一种云台设备300，该云台设备300包括上述任一实施方式的云台控制装置100和云台200，云台200连接有机架210，握持部110通过连接部120可活动地连接于机架210。
上述云台设备300中，握持部110可以一定程度上提供把持力的支撑，能够让用户通过直观的位置控制来控制云台200，降低用户操作云台200的难度，提升云台200运动时的稳定性及一致性，可提升拍摄效果。
需要说明的是，上述对云台控制装置100的实施方式和有益效果的解释说明，也适用于本实施方式的云台设备300，为避免冗余，在此不作详细展开。
