例如,所述手持云台100在静止的状态下,若所述Y轴大致呈竖直设置,且所述云台装置30位于所述握持装置20的上方,则认为所述手持云台100的静止姿态为正立状态。相反地,若所述手持云台100的Y轴大致呈竖直设置,且所述云台装置30位于所述握持装置20的下方,则认为所述手持云台100的静止姿态为倒立状态。若所述手持云台100的Y轴偏离于竖直轴,且所述云台装置30位于所述握持装置20的上方,则认为所述手持云台100的静止姿态为正立的倾斜状态。若所述手持云台100的Y轴偏离于竖直轴,且所述云台装置30位于所述握持装置20的下方,则认为所述手持云台100的静止姿态为倒立的倾斜状态。若所述手持云台100的Y轴大致呈水平设置,则认为所述手持云台100的静止姿态为横持状态。
进一步地,所述云台装置30上还设置有姿态检测传感器38(请参阅图2),所述姿态检测传感器38可以检测所述云台装置30当前的运动状态,以允许所述控制器24根据所述云台装置30当前的运动状态,并结合上述的三个所述电机的转子彼此之间的相对位置,计算出所述手持云台100当前的姿态,从而判断所述手持云台100的状态是否适宜开启。在本实施方式中,所述姿态检测传感器38包括惯性测量传感器。具体而言,所述惯性测量传感器包括三轴角速度传感器及三轴加速度传感器。所述姿态检测传感器38能够检测所述云台装置30当前运行的三个轴的角速度以及所述云台装置30当前运行的三个轴的加速度,并将所述角速度及所述加速度传送至所述控制器24内。所述控制器24将所述姿态检测传感器38所检测的角速度及加速度换算成为所述手持云台当前的姿态,并根据该姿态判断所述手持云台100是否适宜开启。可以理解的是,所述惯性测量传感器还能够用于检测所述转轴机构的角速度及加速度。
在一个具体的实施例中,所述控制器24根据三个所述电机的转子彼此之间的相对位置,以及上述的姿态检测传感器38所检测的角速度及加速度,计算所述手持云台100整体当前的运行姿态时,若计算出所述手持云台100处于前述的正立状态时,或在前述正立的倾斜状态下,其Y轴偏离于竖直轴(即重力方向)的角度小于或等于45°时,或者,所述云台的Y轴偏离于水平轴(即水平方向)的角度大于135°时,则判断所述手持云台100处于可以正常开启的状态;若计算出所述手持云台100处于其他的状态,如倒立状态或横持状态等等时,均判断所述手持云台100处于不适宜开启的状态。
在另一具体的实施例中,所述控制器24根据三个所述电机的转子彼此之间的相对位置,以及上述的姿态检测传感器38所检测的角速度及加速度,计算所述手持云台100整体当前的运行姿态时,若计算出所述手持云台100相对于Y轴、R轴及P轴中的至少一轴以较高的速度或/及角速度运动,则判断所述手持云台100处于不适宜开启的状态。具体地,所述控制器24中还可以预设存储有所述手持云台100相对于Y轴、R轴及P轴运动的预设速度范围及预设角速度范围,所述控制器24将所述手持云台100相对于Y轴、R轴及P轴运动的速度及角速度与所述预设速度范围及所述预设角速度范围比较,若所述速度及角速度中的至少一个未落入所述其对应的预设范围,则判断所述手持云台100正以较高速度运动,不适宜开启。

再如,当所述手持云台处于工作中,用户通过按压所述模式控制按钮以期切换所述手持云台当前的工作状态时,所述模式控制系统能够通过获取所述手持云台的姿态,判断所述手持云台的当前姿态是否满足一预设条件,即,判断所述手持云台是否适宜切换状态,若否,则限制所述手持云台切换工作状态。
甚至,当用户使用所述手持云台搭载所述拍摄装置进行拍摄作业时,若用户期望通过所述手持云台控制所述拍摄装置切换工作模式,如切换拍摄模式、变焦或者变换拍摄方向等,所述模式控制系统能够通过获取所述手持云台的姿态,判断所述手持云台的当前姿态是否满足一预设条件,即,判断所述手持云台的姿态是否适宜所述拍摄装置切换工作模式,若否,则限制所述拍摄装置切换工作模式。
其中,所述模式控制系统及控制方法应用于上述的可移动平台的工作模式切换控制作业中时,所述模式控制系统所接收的改变当前工作模式的控制指令可以包括但不限于以下的指令:开启所述可移动平台的电源,关闭所述可移动平台的电源,开启所述可移动平台的负载,关闭所述可移动平台的负载,改变所述可移动平台的当前工作模式,改变所述可移动平台的负载的当前工作模式。
例如,所述可移动平台可以包括承载装置、搭载在所述承载装置上的云台装置以及承载在所述云台装置上的BB弹发射器。其中,所述承载装置可以为遥控底盘车。当检测到所述BB弹发射器发射BB弹的控制信号时,所述控制器通过获取云台装置的当前姿态信息,判断此时所述可移动平台的状态是否适合发射,例如,当所述控制器根据所述云台装置的当前姿态信息判断BB弹发射器的发射管朝下,则可获知此时所述可移动平台的状态不宜发射。此时,所述控制器不执行发射命令,即,保持所述BB弹发射器的当前工作模式。
再如,所述可移动平台可以包括承载装置、搭载在所述承载装置上的云台装置以及挂载在所述云台装置上的相机。其中,所述承载装置可以为无人飞行器,所述云台装置设置于所述无人飞行器下方。当检测到“一键降落”的控制信号时,所述控制器通过获取所述云台装置的当前姿态信息,判断所述可移动平台的当前状态是否适合降落,例如,所述控制器根据所述云台装置的当前姿态信息判断所述无人机的起落架还未来得及放下,则可获知此时所述可移动平台的状态不宜降落。此时所述控制器不执行立即降落的命令,即,不改变所述无人机的当前工作模式。此时,所述可移动平台的当前姿态信息还可以包括其所处的高度信息(例如,所述无人机所处的飞行高度),所述控制器根据所述云台装置的当前姿态信息判断所述无人机的飞行高度大于一预设时,则可获知此时所述可移动平台的状态不宜降落。
以上实施方式仅用以说明本发明的技术方案而非限制,尽管参照以上实施方式对本发明进行了详细说明,本领域的普通技术人员应当理解,可以对本发明的技术方案进行修改或等同替换都不应脱离本发明技术方案的精神和范围。
