为解决上述问题,本申请实施例提供一种控制方法、手持云台、系统及计算机可读存储介质,通过用户对拨轮键的控制模式配置操作,将拨轮键的控制模式配置为第一控制模式或者第二控制模式,然后在第一控制模式下,响应于用户对拨轮键的转动操作,控制云台运动,以改变拍摄设备的位姿,而在第二控制模式下,响应于用户对拨轮键的转动操作,调整拍摄设备的拍摄参数,通过拨轮键控制云台运动时,减少引入的多余控制量,而通过拨轮键调整拍摄设备的拍摄参数时,不需要用户触碰拍摄设备,可以保证拍摄画面的稳定性,极大地的提高了云台和拍摄参数调节的控制便利性,也提高了拍摄画面的稳定性。
请参阅图1,图1是实施本申请实施例提供的控制方法的手持云台的结构示意图。以下将结合图1,对本申请实施例中的手持云台进行说明。
如图1所示,该手持云台100包括手柄部101、设于手柄部101上的云台102和拨轮键103,云台102用于搭载拍摄设备。可以理解的是,拍摄设备可以与云台102一体设置,拍摄设备为智能手机,当然也可以为其他摄像设备,例如单反相机。其中,云台102包括三轴电机,分别为俯仰(pitch)轴电机1021、横滚(roll)轴电机1022和平移(yaw)轴电机1023,用于调整搭载于云台102上的拍摄设备的平衡姿态,以便随时随地拍摄出高精度的稳定画面。
在一实施例中,用户可以转动拨轮键103,以控制搭载于云台102上的拍摄设备调整拍摄参数或控制云台102运动,以改变搭载于云台102上的拍摄设备的位姿。拨轮键103的控制模式包括第一控制模式和第二控制模式,手持云台100能够根据用户对拨轮键103的控制模式配置操作,将拨轮键103的控制模式配置为第一控制模式或第二控制模式,在第一控制模式下,拨轮键103用于控制云台102的运动,以改变拍摄设备的位姿,第二控制模式下,拨轮键103用于控制搭载于云台102上的拍摄设备调整拍摄参数。

请参阅图2,图2是本申请实施例提供的一种控制方法的步骤示意流程图。该控制方法用于控制云台或者拍摄设备,该云台包括拨轮键,该云台用于搭载拍摄设备,拨轮键能够用于控制云台运动或调整拍摄设备的拍摄参数。
如图2所示,该控制方法包括步骤S101至步骤S103。
S101、根据用户对所述拨轮键的控制模式配置操作,将所述拨轮键的控制模式配置为第一控制模式或者第二控制模式。
其中,在第一控制模式下,拨轮键用于控制云台的运动,以改变拍摄设备的位姿,在第二控制模式下,拨轮键用于调整拍摄设备的拍摄参数,拍摄参数包括跟焦参数、焦距、曝光值、感光度、白平衡和快门速度中的一种或者多种。
在一实施例中,控制模式配置操作包括第一选择操作和第二选择操作,第一选择操作与第二选择操作不同,第一选择操作和第二选择操作可以为用户对拨轮键的功能选择页面内的功能选项的选择操作,该功能选项用于描述拨轮键能够实现的功能。请参阅图3,图3是本申请实施例中的拨轮键的功能选择页面的一示意图,如图3所示,拨轮键的功能选择页面显示有跟焦、ISO(感光度)、光圈、快门、平移轴、俯仰轴、横滚轴和跟焦电机等功能选项。
在一实施例中,将拨轮键的控制模式配置为第一控制模式的方式可以为:控制显示装置显示拨轮键的功能选择页面;响应于用户对该功能选择页面的第一选择操作,将拨轮键的控制模式配置为第一控制模式,且第一控制模式下的拨轮键控制的目标轴向包括云台的一个或者多个轴向。其中,显示装置可以设置于云台的手柄部,也可以设置于与云台连接的终端设备。例如,如图3所示,用户对该功能选择页面的第一选择操作包括对功能选项“平移轴”、“俯仰轴”和“横滚轴”中的一个或多个的选择操作,也即当用户选择功能选项“平移轴”、“俯仰轴”和“横滚轴”中的一个或多个时,将拨轮键的控制模式配置为第一控制模式。通过显示拨轮键的功能选择页面,便于用户快速的切换拨轮键的控制模式,极大地提高了用户体验。
示例性的,如图4所示,用户对该功能选择页面的第一选择操作为用户对功能选项“俯仰轴”的选择操作,因此,将拨轮键的控制模式配置为第一控制模式,且此时拨轮键能够控制云台运动,以使拍摄设备绕俯仰轴转动或者沿俯仰轴移动。如图5所示,用户对该功能选择页面的第一选择操作为用户对功能选项“俯仰轴”和“横滚轴”的选择操作,因此,将拨轮键的控制模式配置为第一控制模式,且此时拨轮键能够控制云台运动,以使拍摄设备绕俯仰轴和横滚轴转动或者沿俯仰轴和横滚轴移动。
在一实施例中,可以确定所述拨轮键控制的轴向;根据所述拨轮键控制轴向,确定摇杆键控制的轴向。也就是说,确定了拨轮键的控制轴向,可以进一步自动设置摇杆键控制的轴向。反之,也是可行的,若用户先设定了摇杆键控制的轴向,可以自动设置拨轮键控制的轴向。
在第一控制模式下,拨轮键可以控制云台的关于yaw/pitch/row轴向中的任一轴向的运动,而其他轴向则由云台的摇杆键来控制。举例来说,用户可以 用右手把持云台的把手,用右手大拇指拨动摇杆(摇杆的上下和左右两个方向分别对应不同的轴向),控制关于其中两个轴向的运动,也就是说右手实现对云台的托举和部分轴向的控制。左手转动拨轮键,控制除该两个轴向以外的轴向的运动。这样,能在不影响托举云台情况下,用双手实现同时控制云台三个轴向的操作,拓展了云台的操控可能性,由此,用户可以在手持云台上完成更多的摄像效果。而在发明人就发明过程之前已知的技术中,若用户想控制手持云台的三个轴向,需要依赖在场的另一用户手持其他控制设备,两人或者多人配合完成手持云台的三个轴向的控制。
在一实施例中,将拨轮键的控制模式配置为第二控制模式的方式可以为:控制显示装置显示拨轮键的功能选择页面;响应于用户对该功能选择页面的第二选择操作,将拨轮键的控制模式配置为第二控制模式,且第二控制模式下的拨轮键可以调节的目标拍摄参数包括跟焦参数、焦距、曝光值、感光度、白平衡和快门速度中的一种或多种。其中,显示装置可以设置于云台的手柄部,也可以设置于与云台连接的终端设备。例如,如图3所示,用户对该功能选择页面的第二选择操作包括对功能选项“跟焦”、“ISO”、“光圈”、“快门”和“跟焦电机”中的一个或多个选择操作,也即当用户选择功能选项为“跟焦”、“ISO”、“光圈”、“快门”和“跟焦电机”中的一个或多个时,将拨轮键的控制模式配置为第二控制模式。通过显示拨轮键的功能选择页面,便于用户快速的切换拨轮键的控制模式,极大地提高了用户体验。
示例性的,如图6所示,用户对该功能选择页面的第二选择操作为用户对功能选项“跟焦”的选择操作,因此,将拨轮键的控制模式配置为第二控制模式,且此时拨轮键能够调整拍摄设备的跟焦参数。如图7所示,用户对该功能选择页面的第二选择操作为用户对功能选项“跟焦电机”的选择操作,因此,将拨轮键的控制模式配置为第二控制模式,且此时拨轮键能够控制与拍摄设备的变焦环或跟焦环卡合的跟焦电机转动,从而调整拍摄设备的焦距或跟焦参数。
在一实施例中,将拨轮键的控制模式配置为第一控制模式的方式可以为:获取用户对拨轮键的功能切换按键的触发操作,若该触发操作为第一触发操作,则将拨轮键的控制模式配置为第一控制模式,并在显示装置显示第一控制模式对应的第一功能选择页面;响应于用户对第一功能选择页面中的功能选项的选择操作,确定第一控制模式下的拨轮键能够控制的云台的一个或者多个轴向。例如,如图8所示,第一功能选择页面包括的功能选项包括“平移轴”、“俯仰轴”和“横滚轴”,如图9所示,用户选择的第一功能选择页面中的功能选项为“平移 轴”,则第一控制模式下的拨轮键能够控制云台的平移轴电机转动。
在一实施例中,将拨轮键的控制模式配置为第二控制模式的方式可以为:获取用户对拨轮键的功能切换按键的触发操作,若该触发操作为第二触发操作,则将拨轮键的控制模式配置为第二控制模式,并在显示装置显示第二控制模式对应的第二功能选择页面;响应于用户对第二功能选择页面中的功能选项的选择操作,确定第二控制模式下的拨轮键能够调整的一种或者多种拍摄参数。例如,如图10所示,第二功能选择页面包括的功能选项包括“跟焦”、“ISO”、“光圈”、“快门”和“跟焦电机”,如图11所示,用户选择的第二功能选择页面中的功能选项为“光圈”,则第二控制模式下的拨轮键能够调整拍摄设备的光圈的取值。
通过设置功能切换按键,便于用户便捷的切换拨轮键的控制模式,同时通过显示拨轮键处于不同控制模式下的功能选择页面,便于用户在不同控制模式下便捷的选择拨轮键能够实现的功能,极大地提高了用户体验。
其中,第一触发操作与第二触发操作不同,例如,第一触发操作为用户对功能切换按键的单击操作,第二触发操作为用户对功能切换按键的双击操作。或者第一触发操作为用户对功能切换按键的双击操作,第二触发操作为用户对功能切换按键的单击操作。或者第一触发操作为用户对功能切换按键的单击操作,第二触发操作为用户对功能切换按键的长按操作。或者第一触发操作为用户对功能切换按键的长按操作,第二触发操作为用户对功能切换按键的单击操作。
S102、在所述第一控制模式下,响应于用户对所述拨轮键的转动操作,控制所述云台运动,以改变所述拍摄设备的位姿。
在拨轮键处于第一控制模式下时,用户可以通过操作拨轮键控制云台运动。例如,响应于用户对拨轮键的转动操作,控制云台运动,以改变拍摄设备的位姿。通过拨轮键控制云台运动时,减少引入的多余控制量,可以保证拍摄画面的稳定性,极大地的提高了云台的控制便利性。
在一实施例中,响应于用户的第一选择操作,选择云台的一个或者多个轴向作为拨轮键控制的目标轴向;响应于用户对拨轮键的转动操作,控制云台运动,以使拍摄设备绕目标轴向转动或者沿目标轴向移动。其中,目标轴向包括俯仰轴方向、横滚轴方向和平移轴方向中的至少一个。通过拨轮键控制云台运动时,减少引入的多余控制量,可以保证拍摄画面的稳定性,极大地的提高了云台的控制便利性。
