随着人们生活水平的提高,人们经常使用单反相机、数码相机和智能手机等拍摄设备拍摄记录日常生活和旅游过程中的风景等,人们在使用拍摄设备拍摄时,通常会手动的调整拍摄设备的曝光值、快门、焦距、焦点和姿态等拍摄参数。目前,人们主要通过对拨轮键的转动来调整拍摄设备的曝光值、快门、焦距、焦点和姿态等拍摄参数,人们转动拨轮键的快慢会影响拍摄参数的调整,如果转动拨轮键的速度较快,会导致拍摄设备无法及时响应用户对拨轮键的转动操作,使得拍摄参数的调整与用户对拨轮键的转动操作不匹配,无法准确地调整拍摄设备的拍摄参数,用户体验不好。
为解决上述问题,本申请实施例提供一种控制方法、装置、手持云台及计算机可读存储介质,该控制方法应用于控制装置,该控制装置用于控制拍摄设备,该控制装置包括拨轮键,该控制装置可以通过有线的方式与拍摄设备连接,也可以通过无线的方式与拍摄设备连接。其中,该拍摄设备包括单反相机、云台相机、数码相机和智能手机等。
在一实施例中,该控制方法还可以应用于手持云台,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,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等。
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。
其中,云台102上设置有惯性测量单元(Inertial measurement unit,IMU),可例如为加速度计或陀螺仪中的至少一种,可以用于测量云台102的姿态和加速度等,以便根据姿态调整云台102的姿态。在一实施例中,手柄部101上也 设置有惯性测量单元(Inertial measurement unit,IMU),可例如为加速度计或陀螺仪中的至少一种,可以用于测量手柄部101的姿态和加速度等,以便根据手柄部101的姿态和云台102的姿态调整云台102的姿态。
其中,手柄部101上还设有操作控键,以便用户操作该操作控键以控制云台102或搭载于云台102上的拍摄设备。该操作控键可例如为按键、扳机、旋钮或者摇杆等,当然也包括其他形式的物理按键。比如,摇杆可以用于控制三个转轴的运动,进而控制云台102的运动。可以理解的是,摇杆也可以用于其他功能,用户通过该操作控键也可以选择拨轮键能够调整的拍摄参数,使得后续手持云台能够响应于用户对拨轮键的转动操作,以控制拍摄设备对拍摄参数进行调整。
其中,手柄部101上还设有显示装置,以便用户通过该显示装置控制云台102或搭载于云台102上的拍摄设备。例如,控制显示装置显示参数选择图标,并响应于用户对该参数选择图标的触发操作,确定待调整的的拍摄参数,使得后续手持云台能够响应于用户对拨轮键的转动操作,以控制拍摄设备对拍摄参数进行调整。

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。该控制方法应用于控制装置,该控制装置包括拨轮键,该控制装置用于根据拨轮键的转动信息,控制拍摄设备调整拍摄参数,使得拍摄参数的调整与拨轮键的转动相匹配,提高拍摄参数的调整准确性。
如图2所示,该控制方法包括步骤S101至步骤S104。
S101、根据所述拨轮键的转动信息确定所述拍摄设备的控制量的输入累积值。
若检测到用户对拨轮键的转动操作,则根据拨轮键的转动信息确定拍摄设备的控制量的输入累积值。其中,该转动信息包括拨轮键的位置、转速和角速度,该控制量用于控制拍摄设备的拍摄参数发生改变,拍摄参数包括但不限于拍摄设备的曝光值、光圈、焦距和焦点。
在一实施例中,在控制拍摄设备调整拍摄参数之前,用户可以从曝光值、光圈、焦距和焦点等中选择一项作为目标拍摄参数进行调整,使得后续控制装置根据拨轮键的转动信息确定拍摄设备的目标拍摄参数的控制量的输入累积值,当用户未选择调整的拍摄参数时,可以将默认的拍摄参数作为目标拍摄参数,例如,默认的拍摄参数为焦距,也即控制装置能够根据拨轮键的转动信息确定拍摄设备的焦距的控制量的输入累积值。
在一实施例中,该控制装置还包括参数选择控键,用户可以通过该参数选择控键从曝光值、光圈、焦距和焦点等拍摄参数中选择一项作为目标拍摄参数进行调整,即可以控制拍摄设备进行变焦、对焦,调整曝光值和光圈大小等,具体为:响应于用户对该参数选择控键的触发操作,确定待调整的目标拍摄参数。其中,用户对该参数选择控键的触发操作包括用户对该参数选择控键的单击操作、双击操作、长按操作和滑动操作中的任一项。例如,用户对该参数选择控键的触发操作为单击操作时,将拍摄设备的曝光值作为待调整的目标拍摄参数,用户对该参数选择控键的触发操作为双击操作时,将拍摄设备的焦距作为待调整的目标拍摄参数,用户对该参数选择控键的触发操作为长按操作时,将拍摄设备的曝光值作为待调整的目标拍摄参数,用户对该参数选择控键的触发操作为滑动操作时,将拍摄设备的焦点作为待调整的目标拍摄参数。通过设置参数选择控件,便于用户简单便捷的选择拍摄设备的待调整的目标拍摄参数,提高用户体验。
在一实施例中,用户也可以通过人机交互界面从曝光值、光圈、焦距和焦点等拍摄参数中选择一项作为目标拍摄参数进行调整,具体为:控制拍摄设备显示参数选择图标,并响应于用户对该参数选择图标的触发操作,确定待调整的目标拍摄参数。其中,用户对该参数选择图标的触发操作包括用户对该参数选择图标的单击操作、双击操作、长按操作和滑动操作中的任一项。例如,用户对该参数选择图标的触发操作为单击操作时,将拍摄设备的曝光值作为待调整的目标拍摄参数,用户对该参数选择图标的触发操作为双击操作时,将拍摄设备的焦距作为待调整的目标拍摄参数,用户对该参数选择图标的触发操作为长按操作时,将拍摄设备的光圈作为待调整的目标拍摄参数,用户对该参数选 择图标的触发操作为滑动操作时,将拍摄设备的焦点作为待调整的目标拍摄参数。通过设置参数选择图标,不需要新增控制按键,便于用户简单便捷的选择拍摄设备的待调整的目标拍摄参数,提高用户体验。
在一实施例中,响应于用户对拨轮键的转动操作,获取拨轮键的转动信息和控制档位系数;根据转动信息和控制档位系数,确定拍摄设备的控制量的输入累积值。其中,该转动信息包括拨轮键的位置、转速和角速度,该控制档位系数用于表征控制拍摄设备调整拍摄参数的快慢程度,该控制档位系数可以采用默认的控制档位系数,也可以由用户自行设置,本申请实施例对此不做具体限定。
在一实施例中,用户设置控制档位系数的方式可以为:控制拍摄设备显示控制档位系数的设置页面,该设置页面包括控制档位系数的设置图标和控制档位系数的确认图标;获取用户对该设置图标的触发操作,并根据该触发操作确定用户设置的控制档位系数;当检测到用户对该确认图标的触发操作时,存储用户设置的控制档位系数至存储器。可以理解的是,控制档位系数的设置图标和确认图标的显示位置和形状可以基于实际情况进行设置,本申请实施例对此不做具体限定。例如,控制档位系数的设置图标为滑动条。
在一实施例中,根据转动信息和控制档位系数,确定拍摄设备的控制量的输入累积值的方式可以为:根据拨轮键的转动信息,确定拨轮键的总转动路程;根据该控制档位系数和拨轮键的总转动路程,确定拍摄设备的控制量的输入累积值,即获取总转动路程、控制档位系数和输入累积值之间的关系式,并根据该关系式、总转动路程和控制档位系数,确定拍摄参数的控制量的输入累积值。其中,总转动路程、控制档位系数和输入累积值之间的关系式可以为P=k×L,也可以为P=k×L+b,P为输入累积值,L为拨轮键的总转动路程,k为控制档位系数,b为增益值。
在一实施例中,根据拨轮键的转动信息,确定拨轮键的总转动路程的方式可以为:获取转动信息中的拨轮键的起始位置和当前位置,并根据拨轮键的起始位置和当前位置,确定拨轮键的总转动路程。其中,由于用户在不断转动拨轮键,因此拨轮键的当前位置也不断发生变化,使得拨轮键的总转动路程也不断发生变化,该拨轮键的起始位置和当前位置可以通过该控制装置内的位置传感器采集确定,该位置传感器包括但不限于霍尔传感器和编码器。
在一实施例中,根据拨轮键的转动信息确定拍摄设备的控制量的输入累积值的方式还可以为:在用户转动拨轮键的过程中,通过位置传感器以间隔预设 时间采集拨轮键的位置,得到拨轮键在不同时刻的位置;根据拨轮键在不同时刻的位置,确定拨轮键在每相邻的两个位置之间的转动路程;根据拨轮键在每相邻的两个位置之间的转动路程和控制档位系数,确定拍摄设备在不同时刻的控制量,并累积拍摄设备在不同时刻的控制量,得到拍摄设备的控制量的输入累积值。其中,预设时间可基于实际情况进行设置,本申请实施例对此不做具体限定,例如,预设时间为0.1秒。
S102、根据在所述拨轮键的转动过程中已向所述拍摄设备发送的控制指令中的控制量,确定已发送给所述拍摄设备的控制量的输出累积值。
在拨轮键的转动过程中,获取已向拍摄设备发送的控制指令,并基于已向拍摄设备发送的控制指令确定已发送给拍摄设备的控制量的输出累积值。其中,该控制指令用于指示拍摄设备根据控制指令中的控制量调整拍摄设备的拍摄参数,不同的控制指令中的控制量不同。可以理解的是,当控制装置还未向拍摄设备发送过控制指令时,控制量的输出累积值为零。例如,控制装置已向拍摄设备发送的控制指令包括控制指令1、控制指令2和控制指令3,且控制指令1、控制指令2和控制指令3中的控制量分别为Δα 1、Δα 2和Δα 3,则控制量的输出累积值为Δα 1+Δα 2+Δα 3
S103、根据所述控制量的所述输入累积值和所述输出累积值,确定所述控制量的剩余累积值。
在获取到控制量的输入累积值和输出累积值之后,基于该控制量的输入累积值和输出累积值,确定控制量的剩余累积值,即确定该控制量的输入累积值与该控制量的输出累积值的差值,并将该控制量的输入累积值与该控制量的输出累积值的差值作为未向拍摄设备发送的控制量的剩余累积值。其中,该剩余累积值用于表征未向拍摄设备发送的控制量的累积值。
在一实施例中,在用户开始对拨轮键进行转动后的预设延迟时长内,控制装置不向拍摄设备发送控制指令,控制装置响应于用户对拨轮键的转动操作,确定该拨轮键在经过预设延迟时长转动后的转动信息,并根据该拨轮键在经过预设延迟时长转动后的转动信息,确定拍摄设备的控制量的输入累积值,且将该输入累积值作为作为控制量的剩余累积值,即由于控制装置还未向拍摄设备发送过控制指令,因此,控制量的输出累积值为零,进而输入累积值相当于控制量的剩余累积值。其中,预设延迟时长可基于实际情况进行设置,本申请实施例对此不做具体限定,例如,预设延迟时长为0.5秒。通过用户开始对拨轮键进行转动后的预设延迟时长内,不向拍摄设备发送控制指令,同时累积控制 量的输入值,可以使得后续调整拍摄设备的拍摄参数时,不受用户对拨轮键的转动速度影响,进而保证拍摄参数的调整能够与用户对拨轮键的转动操作匹配,极大地提高了用户体验。
在一实施例中,在用户开始对拨轮键进行转动后,响应于用户对拨轮键的转动操作,根据拨轮键的转动信息确定拍摄设备的控制量的输入累积值;当该输入累积值大于或等于预设输入累积值时,根据在拨轮键的转动过程中已向拍摄设备发送的控制指令,确定已发送给拍摄设备的控制量的输出累积值,并根据控制量的输入累积值和输出累积值,确定控制量的剩余累积值;当该输入累积值小于预设输入累积值时,不向拍摄设备发送控制指令,即不调整拍摄设备的拍摄参数。通过在输入累积值小于预设输入累积值时,不向拍摄设备发送控制指令,可以避免由于用户误转动拨轮键导致拍摄参数的改变,极大地提高了用户体验。
在一实施例中,在用户对拨轮键的转动操作过程中,当检测到用户停止转动拨轮键时,将控制量的剩余累积值置为零,使得用户停止转动拨轮键后,控制装置不再向拍摄设备发送控制指令,保证拍摄参数的调整能够与用户对拨轮键的转动操作匹配,极大地提高了用户体验。
在一实施例中,在用户对拨轮键的转动操作过程中,当检测到拨轮键的转动方向发生变化时,将控制量的剩余累积值置为零。通过在检测到拨轮键的转动方向发生变化时,将剩余累积值置为零,可以避免之前的剩余累积值对转动方向发生变化后的剩余累积值的影响,提高拍摄参数的调整准确性,也可以保证拍摄参数的调整能够与用户对拨轮键的转动操作匹配,极大地提高了用户体验。
在一实施例中,当检测到拨轮键的转动方向发生变化时,将控制量的剩余累积值置为零后,响应于用户对该拨轮键的转动操作,根据拨轮键的转动信息重新确定拍摄设备的控制量的输入累积值,然后根据在拨轮键的转动过程中已向拍摄设备发送的控制指令中的控制量,重新确定已发送给拍摄设备的控制量的输出累积值;根据重新确定的控制量的剩余累积值置和输出累积值,重新确定控制量的剩余累积值;根据重新确定的剩余累积值调整控制指令中的控制量,并向拍摄设备发送调整得到的控制指令。
例如,拨轮键的转动方向包括顺时针方向和逆时针方向,当拨轮键的转动方向由顺时针方向变化为逆时针方向,则将顺时针方向的控制量的剩余累积值置为零,并确定逆时针方向的控制量的剩余累积值;又例如,当拨轮键的转动 方向由逆时针方向变化为顺时针方向,则将逆时针方向的控制量的剩余累积值置为零,并确定顺时针方向的控制量的剩余累积值。
步骤S104、根据所述剩余累积值调整未发送的控制指令中的控制量的大小,并向所述拍摄设备发送调整得到的所述控制指令。
在确定控制量的剩余累积值后,基于控制量的剩余累积值,调整该控制指令中的控制量,以调整该控制指令,并向该拍摄设备发送调整得到的控制指令,使得拍摄设备能够按照调整后的控制指令中的控制量调整拍摄设备的拍摄参数。
其中,用户通过该拨轮键能够控制拍摄设备进行调焦,即能够控制拍摄设备调整拍摄设备的跟焦参数或者变焦参数,调整拍摄设备的跟焦参数是指调整拍摄设备的焦平面的位置,调整拍摄设备的变焦参数是指调整拍摄设备的焦距,例如,对于手机等拍摄设备主要是数码变焦,对于单反相机等拍摄设备主要是光学变焦和光学跟焦,即光学变焦是通过调整变焦参数对应的光学元件实现的,而光学跟焦是通过调整跟焦参数对应的光学元件实现的。
在一实施例中,在用户转动拨轮键的过程中,通过位置传感器以间隔预设时间采集拨轮键的当前位置,并获取位置传感器在上一个时刻的采集到的拨轮键的历史位置;根据拨轮键的当前位置和历史位置,确定拨轮键当前输入的控制量;根据拨轮键当前输入的控制量,从多个调焦档位中选择对应的调焦档位作为目标调焦档位,其中,存在至少一种控制量能够对应选择不同的调焦档位;根据目标调焦档位,生成调焦控制指令,并向拍摄设备发送调焦控制指令,使得拍摄设备基于调焦控制指令中的控制量控制焦平面的移动速度或移动距离。由于存在至少一种控制量能够对应选择不同的调焦档位,使得拍摄设备的调焦控制能够与用户对调焦操作部件的操作相匹配,进而准确地控制拍摄设备进行调焦,极大地提高了用户体验。
其中,该调焦档位可以用于表征焦平面移动速度的档位,档位越高,则焦平面移动速度越快,档位越低,焦平面移动速度越慢;该调焦档位也可以用于表征变焦参数的变化速度的档位,档位越高,变焦参数的变化速度越快,档位越低,变焦参数的变化速度越慢,至少一种控制量是指与多个调焦档位各自对应的控制量均不相同的当前输入的控制量。
在一实施例中,存在至少一种控制量能够对应选择不同的调焦档位,例如,多个调焦档位分别为调焦档位1、调焦档位2、调焦档位3和调焦档位4,且调焦档位1、调焦档位2、调焦档位3和调焦档位4对应的控制量分别为3、5、8和12,第一次输入的控制量为6,由于多个调焦档位中不存在与控制量6相同 的调焦档位,则将调焦档位2作为目标调焦档位,第二次输入的控制量也为6,目标调焦档位仍为调焦档位2,第三次输入的控制量也为6,此时由于前两次输出的控制量均为5,因此还剩余控制量2未被输出,而第三次继续输入的控制量为6,则未输出的控制量共计为8,因此,可以将调焦档位3作为目标调焦档位,从而能够将未输出的控制量2和输入的控制量6输出。因此,输入的控制量6能够对应选择调焦档位2和调焦档位3这两个不同的调焦档位。
在一实施例中,相同的控制量能够对应选择不同的调焦档位。例如,调焦档位1、调焦档位2、调焦档位3和调焦档位4对应的控制量分别为3、5、8和12,第一次输入的控制量为6,则将调焦档位2作为目标调焦档位,第二次输入的控制量也为6,目标调焦档位仍为调焦档位2,第三次输入的控制量为1,此时由于前两次输出的控制量均为5,因此还剩余控制量2未被输出,而第三次继续输入的控制量为3,则未输出的控制量共计为5,因此,可以将调焦档位2作为目标调焦档位,从而能够将未输出的控制量2和输入的控制量1输出。因此,根据第一次或第二次输入的控制量6选择的调焦档位为调焦档位2,根据第三次输入的控制量3选择的调焦档位也为调焦档位2,也即相同的控制量能够对应选择不同的调焦档位。
在一实施例中,不同的控制量能够对应选择不同的调焦档位。例如,调焦档位1、调焦档位2、调焦档位3和调焦档位4对应的控制量分别为3、5、8和12,第一次输入的控制量为8,则将调焦档位3作为目标调焦档位,第二次输入的控制量为15,则将调焦档位4作为目标调焦档位,此时未输出的控制量为3,第三次输入的控制量为10,则将调焦档位3作为目标调焦档位,此时未输出的控制量共计为3+2=5,第四次输入的控制量为7,由于之前未输出的控制量共计为5,因此可以将调焦档位4作为目标调焦档位,从而能够将未输出的控制量5和输入的控制量7输出。第一次输入的控制量为8对应的调焦档位为调焦档位3,第二次输入的控制量为15对应的调焦档位为调焦档位4。
在一实施例中,如图3所示,步骤S104包括:子步骤S1041至S1042。
S1041、根据所述剩余累积值所处的取值范围,确定目标控制量;
S1042、将未发送的控制指令中的控制量调整为所述目标控制量。
在一实施例中,获取预存的剩余累积值所处的取值范围与控制量之间的映射关系,并根据剩余累积值所处的取值范围和该映射关系,确定拍摄参数的目标控制量。其中,若剩余累积值所处的取值范围不同,则目标控制量不同,剩余累积值所处的取值范围与控制量之间的映射关系可基于实际情况进行设置, 本申请实施例对此不做具体限定。
在一实施例中,在获取预存的剩余累积值所处的取值范围与控制量之间的映射关系之前,确定剩余累积值是否小于或等于预设预设剩余累积值,当确定该剩余累积值小于或等于预设剩余累积值时,获取预存的剩余累积值所处的取值范围与控制量之间的映射关系;根据该映射关系和剩余累积值所处的取值范围,确定目标控制量;当确定剩余累积值大于预设剩余累积值时,将预设的最大控制量作为目标控制量。其中,预设剩余累积值是根据最大控制量、预设延迟时长和控制指令的最大发送频率确定的,预设的最大控制量和预设延迟时长可基于实际情况进行设置,本申请实施例对此不做具体限定。
其中,控制指令的最大发送频率与拍摄设备的厂商和型号有关,例如,可以通过对市面上不同厂商的不同型号的拍摄设备进行实验,从而确定不同厂商的不同型号的拍摄设备对应的最大发送频率,具体为:按照不同的发送频率向拍摄设备发送控制指令,直至已发送的控制指令中的控制量的输出累积值达到预设剩余累积值,得到不同发送频率的指令发送个数,并将该指令发送个数最多的发送频率作为该拍摄设备的控制指令的最大发送频率。
在确定目标控制量后,将未发送的控制指令中的控制量调整为该目标控制量,以调整未发送的控制指令,便于后续向拍摄设备发送调整得到的控制指令,使得拍摄设备能够按照调整得到的控制指令中的目标控制量调整拍摄设备的拍摄参数。
在一实施例中,如图4所示,步骤S104包括:子步骤S1043至S1045。
S1043、获取所述剩余累积值的变化速度;
S1044、根据所述变化速度和所述剩余累积值所处的取值范围,确定目标控制量;
S1045、将未发送的控制指令中的控制量调整为所述目标控制量。
其中,该剩余累积值的变化速度与用户转动拨轮键的速度和控制装置向拍摄设备发送控制指令的频率有关。通过该剩余累积值的变化速度和该剩余累积值所处的取值范围调整控制指令中的控制量,使得后续基于该控制指令中的控制量调整拍摄参数时,能够保证拍摄参数的调整能够与用户对拨轮键的转动操作匹配,极大地提高了用户体验。
在一实施例中,获取剩余累积值的变化速度的方式可以为:获取历史剩余累积值和该历史剩余累积值与该剩余累积值之间的间隔时间;确定该历史剩余累积值与剩余累积值之间的差值,并根据该历史剩余累积值与剩余累积值之间 的差值以及该历史剩余累积值与该剩余累积值之间的间隔时间,确定剩余累积值的变化速度。其中,该历史剩余累积值与该剩余累积值之间的间隔时间可基于实际情况进行设置,本申请实施例对此不做具体限定。
在一实施例中,根据该剩余累积值的变化速度和该剩余累积值所处的取值范围,确定目标控制量的方式可以为:获取变化速度、剩余累积值所处的取值范围和控制量之间的映射关系,并根据该映射关系、该剩余累积值的变化速度和该剩余累积值所处的取值范围,确定目标控制量。其中,变化速度、剩余累积值所处的取值范围和控制量之间的映射关系可基于实际情况进行设置,本申请实施例对此不做具体限定。通过变化速度、剩余累积值所处的取值范围和控制量之间的映射关系,可以快速地确定与该剩余累积值的变化速度和该剩余累积值所处的取值范围对应的目标控制量。
在一实施例中,根据该剩余累积值的变化速度和该剩余累积值所处的取值范围,确定目标控制量的方式还可以为:当确定该变化速度小于或等于预设变化速度时,获取预存的剩余累积值所处的取值范围与控制量之间的映射关系;根据剩余累积值所处的取值范围与控制量之间的映射关系以及剩余累积值所处的取值范围,确定目标控制量;当确定该变化速度大于预设变化速度时,将预设的最大控制量作为目标控制量。其中,预设变化速度和预设的最大控制量可基于实际情况进行设置,本申请实施例对此不做具体限定。通过在变化速度小于或等于设定值时,基于剩余累积值所处的取值范围,确定目标控制量,而在变化速度大于设定值时,将最大控制量作为目标控制量,使得后续基于该控制指令中的控制量调整拍摄参数时,能够保证拍摄参数的调整能够与用户对拨轮键的转动操作匹配,极大地提高了用户体验。
在一实施例中,控制装置按照设定的最大发送频率发送调整后的控制指令。其中,该最大发送频率与拍摄设备的厂商和型号有关,例如,可以通过对市面上不同厂商的不同型号的拍摄设备进行实验,从而确定不同厂商的不同型号的拍摄设备对应的最大发送频率,具体为:按照不同的发送频率向拍摄设备发送控制指令,直至已发送的控制指令中的控制量的输出累积值达到预设剩余累积值,得到不同发送频率的指令发送个数,并将该指令发送个数最多的发送频率作为该拍摄设备的控制指令的最大发送频率。
在一实施例中,如图5所示,步骤S104包括:子步骤S1046至S1048。
S1046、根据所述剩余累积值所处的取值范围,确定目标控制量;
S1047、根据所述剩余累积值和所述目标控制量,确定所述控制指令的目 标发送频率;
S1048、按照所述目标发送频率向所述拍摄设备发送调整得到的所述控制指令。
通过剩余累积值和目标控制量,确定控制指令的目标发送频率,能够自适应地调整控制指令的发送频率,使得后续按照自适应的发送频率向拍摄设备发送控制指令后,拍摄设备的拍摄参数的调整速度能够与用户转动拨轮键的速度相匹配,极大地提高了用户体验。
可以理解的是,由于用户转动拨轮键的速度通常是变化的,因此在转动操作过程中的不同时刻下的控制量的剩余累积值也不同,导致控制装置在转动操作过程中的不同时间段内会以不同的发送频率向拍摄装置发送控制指令,通过不同发送频率的组合,可以灵活的调整拍摄设备的参数的变化速率,极大地提高了用户体验。
在一实施例中,根据剩余累积值和目标控制量,确定控制指令的目标发送频率的方式可以为:根据剩余累积值和目标控制量,确定控制指令的发送次数,即用剩余累积值除以目标控制量,得到控制指令的发送次数;根据发送次数和预设延迟时长,确定控制指令的目标发送频率,即用发送次数除以预设延迟时长,得到控制指令的目标发送频率。其中,预设延迟时长可基于实际情况进行设置,本申请实施例对此不做具体限定。
在一实施例中,向拍摄设备发送调整得到的控制指令的方式还可以为:获取剩余累积值的变化速度;根据变化速度,确定控制指令的目标发送频率;按照目标发送频率向拍摄设备发送调整后的控制指令。通过剩余累积值的变化速度,能够自适应地调整控制指令的发送频率,使得后续按照自适应的发送频率向拍摄设备发送控制指令后,拍摄设备的拍摄参数的调整速度能够与用户转动拨轮键的速度相匹配,极大地提高了用户体验。
在一实施例中,根据变化速度,确定控制指令的目标发送频率的方式可以为:确定该变化速度所处的变化速度范围;根据该变化速度所处的变化速度范围和预设的变化速度范围与指令发送频率之间的映射关系,确定控制指令的目标发送频率。其中,变化速度范围与指令发送频率之间的映射关系可基于实际情况进行设置,本申请实施例对此不做具体限定。通过变化速度范围与指令发送频率之间的映射关系可以快速的获取到与该变化速度所处的变化速度范围对应的指令发送频率。
上述实施例提供的控制方法,通过拨轮键的转动信息确定拍摄设备的控制 量的输入累积值,并根据在拨轮键的转动过程中已向拍摄设备发送的控制指令,确定已向拍摄设备发送的控制量的输出累积值,根据该输入累积值和输出累积值,确定剩余累积值,然后根据该剩余累积值调整该控制指令中的控制量的大小,并向拍摄设备发送调整得到的控制指令,使得拍摄设备的拍摄参数的调整能够与拨轮键的转动相匹配,进而准确地调整拍摄设备的拍摄参数,极大地提高了用户体验。
请参阅图6,图6是本申请实施例提供的另一种控制方法的步骤示意流程图。该控制方法应用于控制装置,控制装置用于控制拍摄设备,控制装置包括调焦操作部件。
如图6所示,该控制方法包括步骤S201至步骤S203。
S201、获取所述调焦操作部件当前输入的控制量。
该调焦操作部件可以包括拨轮键,也可以包括其它实体按键,例如,摇杆,推动摇杆,记录推杆后的杆位相对于摇杆基准位的偏差(角度偏差、距离偏差),并根据该偏差确定当前输入的控制量。除此之外该调焦操作部件也可以是触控屏幕,比如说在触控屏幕上拖动虚拟的拨轮键、或者触压虚拟的按键。根据用户在触控屏上的触控操作,确定当前输入的控制量。
在一实施例中,若调焦操作部件为拨轮键,则根据该拨轮键的转动信息确定拨轮键当前输入的控制量。其中,转动信息包括拨轮键的转速、位置和角速度中的至少一项。在另一实施例中,在用户转动拨轮键的过程中,通过位置传感器以间隔预设时间采集拨轮键的当前位置,并获取位置传感器在上一个时刻的采集到的拨轮键的历史位置;根据拨轮键的当前位置和历史位置,确定拨轮键当前输入的控制量,即根据拨轮键的当前位置和历史位置,确定拨轮键的转动路程,并将该转动路程对应的控制量作为当前输入的控制量,或者,确定拨轮键的转动路程与预设时间的差值,得到拨轮键的转速,并将该转速对应的控制量作为当前输入的控制量。
S202、根据所述当前输入的控制量,从多个调焦档位中选择对应的调焦档位作为目标调焦档位,其中,存在至少一种控制量能够对应选择不同的所述调焦档位。
其中,该调焦档位可以用于表征焦平面移动速度的档位,档位越高,则焦平面移动速度越快,档位越低,焦平面移动速度越慢;该调焦档位也可以用于表征变焦参数的变化速度的档位,档位越高,变焦参数的变化速度越快,档位越低,变焦参数的变化速度越慢,至少一种控制量是指与多个调焦档位各自对 应的控制量均不同的当前输入的控制量。
在一实施例中,若当前输入的控制量与至少一种控制量的种类相同,即当前输入的控制量与多个调焦档位各自对应的控制量均不同,则获取调焦操作部件输入当前输入的控制量的持续时间;若该持续时间大于或等于预设时间,则根据当前输入的控制量,从多个调焦档位中重新选择对应的调焦档位,以改变目标调焦档位;若持续时间小于预设时间,则将选择的调焦档位继续作为目标调焦档位,以保持目标调焦档位不变。由于不断的输入控制量,而输出的控制量跟不上输入的控制量的变化,导致未输出的控制量不断增多,所以需要跳变调焦档位,从而能够归一化不同类型拍摄设备的调焦档位,实现统一的控制不同类型的拍摄设备的调焦。
在一实施例中,根据当前输入的控制量,从多个调焦档位中重新选择对应的调焦档位,以改变目标调焦档位的方式可以为:若该持续时间大于或等于预设时间,则根据当前输入的控制量,从多个调焦档位中选择档位高于目标调焦档位的调焦档位,以改变目标调焦档位。具体为:若该持续时间大于或等于预设时间,则获取未输出的控制量,并将当前输入的控制量和未输出的控制量进行求和,得到实际需要输出的控制量,然后根据实际需要输出的控制量,从多个调焦档位中选择档位高于目标调焦档位的调焦档位,以改变目标调焦档位。
例如,预设时间为0.2秒,多个调焦档位分别为调焦档位1、调焦档位2、调焦档位3和调焦档位4,且调焦档位1、调焦档位2、调焦档位3和调焦档位4对应的控制量分别为3、5、8和12,第一次输入的控制量为6,由于多个调焦档位中不存在与控制量6相同的调焦档位,则将调焦档位2作为目标调焦档位,第二次输入的控制量也为6,目标调焦档位仍为调焦档位2,第三次输入的控制量也为6,且输入控制量的时间超过0.2秒,此时由于前两次输出的控制量均为5,因此还剩余控制量2未被输出,而第三次继续输入的控制量为6,则未输出的控制量共计为8,因此,选择调焦档位3作为目标调焦档位,也即第三次选择的调焦档位高于前面两次选择的调焦档位,通过选择调焦档位3作为目标调焦档位能够将未输出的控制量2和输入的控制量6输出。
在一实施例中,根据当前输入的控制量,从多个调焦档位中重新选择对应的调焦档位,以改变目标调焦档位的方式可以为:若该持续时间大于或等于预设时间,则根据当前输入的控制量,从多个调焦档位中选择档位低于目标调焦档位的调焦档位,以改变目标调焦档位。具体为:若该持续时间大于或等于预设时间,则获取未输出的控制量,并将当前输入的控制量和未输出的控制量进 行求和,得到实际需要输出的控制量,然后根据实际需要输出的控制量,从多个调焦档位中选择档位低于目标调焦档位的调焦档位,以改变目标调焦档位。
例如,预设时间为0.2秒,调焦档位1、调焦档位2、调焦档位3和调焦档位4对应的控制量分别为3、5、8和12,第一次输入的控制量为11,则将调焦档位4作为目标调焦档位,第二次输入的控制量也为11,目标调焦档位仍为调焦档位4,第三次输入的控制量为11,目标调焦档位仍为调焦档位4,第四次继续输入的控制量为11,且输入控制量的时间超过0.2秒,此时由于前三次输出的控制量均为12,因此未输出的控制量为-3,则实际需要输出的控制量11-3=8,因此,选择调焦档位3作为目标调焦档位,也即第四次选择的调焦档位低于前面三次选择的调焦档位,通过选择调焦档位3作为目标调焦档位能够输出实际需要输出的控制量8。
在一实施例中,存在至少一种控制量能够对应选择不同的调焦档位,例如,多个调焦档位分别为调焦档位1、调焦档位2、调焦档位3和调焦档位4,且调焦档位1、调焦档位2、调焦档位3和调焦档位4对应的控制量分别为3、5、8和12,第一次输入的控制量为6,由于多个调焦档位中不存在与控制量6相同的调焦档位,则将调焦档位2作为目标调焦档位,第二次输入的控制量也为6,目标调焦档位仍为调焦档位2,第三次输入的控制量也为6,此时由于前两次输出的控制量均为5,因此还剩余控制量2未被输出,而第三次继续输入的控制量为6,则未输出的控制量共计为8,因此,可以将调焦档位3作为目标调焦档位,从而能够将未输出的控制量2和输入的控制量6输出。因此,输入的控制量6能够对应选择调焦档位2和调焦档位3这两个不同的调焦档位。
在一实施例中,相同的控制量能够对应选择不同的调焦档位。例如,调焦档位1、调焦档位2、调焦档位3和调焦档位4对应的控制量分别为3、5、8和12,第一次输入的控制量为6,则将调焦档位2作为目标调焦档位,第二次输入的控制量也为6,目标调焦档位仍为调焦档位2,第三次输入的控制量为1,此时由于前两次输出的控制量均为5,因此还剩余控制量2未被输出,而第三次继续输入的控制量为3,则未输出的控制量共计为5,因此,可以将调焦档位2作为目标调焦档位,从而能够将未输出的控制量2和输入的控制量1输出。因此,根据第一次或第二次输入的控制量6选择的调焦档位为调焦档位2,根据第三次输入的控制量3选择的调焦档位也为调焦档位2,也即相同的控制量能够对应选择不同的调焦档位。
在一实施例中,不同的控制量能够对应选择不同的调焦档位。例如,调焦 档位1、调焦档位2、调焦档位3和调焦档位4对应的控制量分别为3、5、8和12,第一次输入的控制量为8,则将调焦档位3作为目标调焦档位,第二次输入的控制量为15,则将调焦档位4作为目标调焦档位,此时未输出的控制量为3,第三次输入的控制量为10,则将调焦档位3作为目标调焦档位,此时未输出的控制量共计为3+2=5,第四次输入的控制量为7,由于之前未输出的控制量共计为5,因此可以将调焦档位4作为目标调焦档位,从而能够将未输出的控制量5和输入的控制量7输出。第一次输入的控制量为8对应的调焦档位为调焦档位3,第二次输入的控制量为15对应的调焦档位为调焦档位4。
在一实施例中,若当前输入的控制量与至少一种控制量的种类不同,即多个调焦档位中存在至少一个调焦档位对应的控制量与当前输入的控制量相同,则从多个调焦档位中选择控制量与当前输入的控制量相同对应的调焦档位作为目标调焦档位。例如,调焦档位1、调焦档位2、调焦档位3和调焦档位4对应的控制量分别为3、5、8和12,当前输入的控制量为8,则选择调焦档位3作为目标调焦档位,又例如,当前输入的控制量为5,则选择调焦档位2作为目标调焦档位。
S203、根据所述目标调焦档位,对所述拍摄设备进行调焦控制。
其中,调焦控制包括调整拍摄设备的跟焦参数或者变焦参数,调整拍摄设备的跟焦参数是指调整拍摄设备的焦平面的位置,调整拍摄设备的变焦参数是指调整拍摄设备的焦距,例如,对于手机等拍摄设备主要是数码变焦,对于单反相机等拍摄设备主要是光学变焦和光学跟焦,即光学变焦是通过调整变焦参数对应的光学元件实现的,而光学跟焦是通过调整跟焦参数对应的光学元件实现的。
在一实施例中,根据该目标调焦档位,生成调焦控制指令,其中,该调焦控制指令中的控制量与该目标调焦档位对应的控制量相同;向拍摄设备发送该调焦控制指令。其中,调焦控制指令用于指示拍摄设备根据该调焦控制指令中的控制量控制焦平面的移动速度或移动距离,目标调焦档位不同,则调焦控制指令不同。
上述实施例提供的控制方法,通过获取调焦操作部件当前输入的控制量,并根据当前输入的控制量,从多个调焦档位中选择对应的调焦档位作为目标调焦档位,然后根据目标调焦档位,对拍摄设备进行调焦控制,由于存在至少一种控制量能够对应选择不同的调焦档位,使得拍摄设备的调焦控制能够与用户对调焦操作部件的操作相匹配,进而准确地控制拍摄设备进行调焦,极大地提 高了用户体验。
