目前,手持云台给拍摄设备的使用带来了极大的便利,人们可以在各种场景、各种运动模式下简单轻松地拍出图像稳定和变焦流畅的画面。在拍摄过程中用户需要根据环境中的光影变化,动态的调整拍摄设备的各种参数,由于不同厂家、不同系列以及不同型号的拍摄设备的参数可调范围不同,为了使得手持云台能够适配不同的拍摄设备,需要在开发时尽可能的适配不同厂家、不同系列以及不同型号的拍摄设备,但拍摄设备的厂家、系列以及型号较多,需要花费大量的资源去适配拍摄设备,但也无法完全适配市面上的全部拍摄设备,用户体验不好。
为解决上述问题,本申请实施例提供了一种参数自适应方法、手持云台、系统及计算机可读存储介质,通过向拍摄设备发送多个控制指令,使得拍摄设备将目标拍摄参数的取值配置为控制指令对应的预设取值,然后获取拍摄设备返回的目标拍摄参数的取值的配置结果,并根据配置结果确定目标拍摄参数的取值范围,不需要在开发时尽可能的适配不同厂家、不同系列以及不同型号的拍摄设备,能够实现自适应的调整不同拍摄设备的拍摄参数的取值范围,极大地提高了用户体验。
随着使用拍摄设备的时间不断增加,存在拍摄设备的拍摄参数的一部分取值不支持的问题,而通过向拍摄设备发送多个控制指令,使得拍摄设备将目标拍摄参数的取值配置为控制指令对应的预设取值,然后获取拍摄设备返回的目标拍摄参数的取值的配置结果,并根据配置结果确定目标拍摄参数的取值范围,可以重新确定拍摄设备的拍摄参数的取值范围,从而解决随着使用拍摄设备的时间不断增加,拍摄设备的拍摄参数的一部分取值不支持的问题。
请参阅图1,图1是实施本申请实施例提供的参数自适应方法的手持云台的结构示意图。以下以图1对手持云台的各部件进行解释说明。
如图1所示,该手持云台100包括手柄部101和设于手柄部101上的云台 102,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,也可以外接于云台102,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。

请参阅图2,图2是本申请实施例提供的一种参数自适应方法的步骤示意流程图。该参数自适应方法可以应用于手持云台,以实现自适应的调整不同拍摄设备的拍摄参数的取值范围。
具体地,如图1所示,该参数自适应方法包括步骤S101至步骤S102。
S101、向所述拍摄设备发送多个控制指令。
其中,所述控制指令包括目标拍摄参数的预设取值。所述控制指令用于指示所述拍摄设备将目标拍摄参数的取值配置为对应的预设取值。
在一种可选的实施方式中,每一所述控制指令可以包括单个取值。每一所述控制指令也可以包括多个不同的取值。比如,控制指令用于指示拍摄设备依次将目标拍摄参数设置为5、10、15等等。
在需要调整拍摄设备的拍摄参数的取值范围时,云台向拍摄设备发送控制指令,以指示拍摄设备基于该控制指令将目标拍摄参数的取值配置为对应的预设取值。其中,目标拍摄参数包括曝光参数、跟焦参数和变焦参数中的任一项, 曝光参数包括曝光值、光圈值和快门速度等。
在一实施例中,以间隔预设时间向拍摄设备发送不同的控制指令。其中,不同的控制指令对应的目标拍摄参数的预设取值。可以理解的是,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。通过间隔预设时间向拍摄设备发送不同的控制指令,使得拍摄设备能够基于不同的控制指令给目标拍摄参数配置不同的预设取值,从而可以得到目标拍摄参数的不同预设取值的配置结果,便于确定目标拍摄参数的取值范围。
在一实施例中,如图3所示,步骤S101具体包括:子步骤S1011至S1012。
S1011、获取参数自适应指令,并根据所述参数自适应指令,获取目标拍摄参数的预设取值集合。
其中,参数自适应指令可以由用户手动触发,也可以基于预设条件自动触发,预设条件包括云台的设备标识库中不存在接入云台的拍摄设备的设备标识和接入云台的拍摄设备的累积使用时间超过预设使用时间,该设备标识用于表示所述拍摄设备的厂商、类型和/或型号,拍摄设备的累积使用时间为从拍摄设备首次开机时开始记录的使用时间。可以理解的是,预设使用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,预设使用时间为半年,因此,当接入云台的拍摄设备的累积使用时间超过半年,则自动触发参数自适应指令。
在一实施例中,用户手动触发参数自适应指令的方式可以为:响应于用户对参数自适应控键的触发操作,触发参数自适应指令;或者通过显示装置显示参数自适应弹窗,其中,参数自适应弹窗内显示有参数自适应图标,响应于用户对参数自适应图标的触控操作,触发参数自适应指令。其中,显示装置可以设置于与云台连接的手柄部,和/或可以设置于与云台连接的终端设备。通过提供参数自适应指令的不同触发方式,方便用户触发参数自适应指令,提高用户体验。
在一实施例中,获取接入云台的拍摄设备的设备标识,并确定云台的设备标识库中是否存在接入云台的拍摄设备的设备标识;若云台的设备标识库中不存在接入云台的拍摄设备的设备标识,则输出第一提示信息,以提示用户控制云台进行参数自适应;响应于用户对参数自适应控键的触发操作或参数自适应图标的触控操作,触发参数自适应指令。通过提示用户控制云台进行参数自适应,可以及时告知用户需要对云台进行参数自适应,极大的提高了用户体验。
在一实施例中,根据参数自适应指令,获取目标拍摄参数的预设取值集合 的方式可以为:根据该参数自适应指令中的设备标识,获取目标拍摄参数的预设取值集合,即根据该参数自适应指令中的设备标识以及设备标识与预设取值集合之间的映射关系,获取目标拍摄参数的预设取值集合。其中,设备标识用于表示拍摄设备的厂商、类型和/或型号。通过参数自适应指令中的设备标识获取目标拍摄参数的预设取值集合,使得获取到的预设取值集合更加符合接入云台的拍摄设备的厂商、类型和/或型号,便于后续更加准确地确定目标拍摄参数的取值范围。
在一实施例中,根据参数自适应指令中的设备标识,获取目标拍摄参数的预设取值集合的方式可以为:获取设备标识对应的多个预设取值集合,并获取拍摄设备的参数控制档位;根据参数控制档位从多个预设取值集合中确定目标拍摄参数的预设取值集合。由于一个拍摄设备具有不同的参数控制档位,且不同的参数控制档位能够支持的拍摄参数的取值不同,因此通过参数控制档位从设备标识对应的多个预设取值集合中确定目标拍摄参数的预设取值集合,使得获取到的预设取值集合更加符合接入云台的拍摄设备的参数控制档位、厂商、类型和/或型号,便于后续更加准确地确定目标拍摄参数的取值范围。
S1012、根据所述预设取值集合中的预设取值,生成对应的控制指令,并向所述拍摄设备发送生成的所述控制指令。
在确定目标拍摄参数的预设取值集合后,以间隔预设时间从预设取值集合中选择不同的预设取值,并根据选择的预设取值,生成对应的控制指令,且向拍摄设备发送生成的控制指令,使得拍摄设备能够在不同的时刻接收到不同的控制指令,从而基于不同的控制指令给目标拍摄参数配置不同的预设取值,可以得到目标拍摄参数的不同预设取值的配置结果,然后将目标拍摄参数的不同预设取值的配置结果发送给云台,便于云台基于目标拍摄参数的不同预设取值的配置结果确定目标拍摄参数的取值范围。
S102、获取所述拍摄设备返回的所述目标拍摄参数的取值的配置结果。

S103、根据多个所述控制指令对应的所述配置结果确定所述目标拍摄参数的取值范围。
拍摄设备在接收到云台发送的控制指令时,基于该控制指令将目标拍摄参数的取值配置为对应的预设取值,然后拍摄设备读取目标拍摄参数的当前取值,并将目标拍摄参数的当前取值与控制指令中的预设取值进行比较,得到目标拍 摄参数的预设取值的配置结果,并将目标拍摄参数的预设取值的配置结果发送至云台,云台获取拍摄设备返回的目标拍摄参数的不同预设取值的配置结果。其中,如果目标拍摄参数的当前取值与控制指令中的预设取值相同,则目标拍摄参数的预设取值的配置结果为配置成功,拍摄设备的目标拍摄参数支持配置成功的预设取值,而如果目标拍摄参数的当前取值与控制指令中的预设取值不同,则目标拍摄参数的预设取值的配置结果为配置失败,拍摄设备的目标拍摄参数不支持配置失败的预设取值。
在一实施例中,根据配置结果确定目标拍摄参数的取值范围的方式可以为:从目标拍摄参数的预设取值集合中获取配置结果为配置成功的多个预设取值;根据多个预设取值,确定目标拍摄参数的取值范围。其中,目标拍摄参数包括曝光参数、跟焦参数和变焦参数中的任一项,目标拍摄参数的取值范围的端点值位于目标拍摄参数的预设取值集合内。通过目标拍摄参数的不同预设取值的配置结果为配置成功的多个预设取值可以准确地确定目标拍摄参数的取值范围,从而实现自适应的调整不同拍摄设备的拍摄参数的取值范围,极大地提高了用户体验。
在一实施例中,取值范围可以包括端值。根据多个预设取值,确定目标拍摄参数的取值范围的方式可以为:从多个预设取值中选择最大的预设取值作为第一端点值,从多个预设取值中选择最小的预设取值作为第二端点值;将第一端点值和第二端点值之间的取值作为目标拍摄参数的取值范围,其中,目标拍摄参数的取值范围包括第一端点值和第二端点值。
在一实施例中,取值范围可以也可以用多个离散的取值点来表示。也可以通过端值和取值间隔来表示。或者,可以通过一个中心取值与其临近的正负取值范围来表示,例如±5等。或者,可以通过一个基础取值,及其倍乘来标识,例如,基础取值为X,取值范围内取值可以是1X,2X,3X等等。上述仅为举例性说明,并不用于限定其实施可能性。
在一实施例中,在确定一种目标拍摄参数的取值范围后,可以继续确定其余目标拍摄参数的取值范围,例如,先确定跟焦参数的取值范围,之后确定变焦参数的取值范围,最后再确定曝光参数的取值范围。其中,在确定不同目标拍摄参数的取值范围时,不同的目标拍摄参数可以采用不同的预设取值集合和间隔时间,例如,确定跟焦参数的取值范围时,以间隔第一预设时间向拍摄设备发送第一预设取值集合中的预设取值对应的控制指令,而确定变焦参数的取值范围时,以间隔第二预设时间向拍摄设备发送第二预设取值集合中的预设取 值对应的控制指令,而确定曝光参数的取值范围时,以间隔第三预设时间向拍摄设备发送第三预设取值集合中的预设取值对应的控制指令。第一预设时间、第二预设时间和第三预设时间不同,第一预设取值集合、第二预设取值集合和第三预设取值集合不同。
在一实施例中,在确定目标拍摄参数的取值范围后,根据目标拍摄参数的取值范围,调整显示装置当前显示的参数控制图标。其中,参数控制图标用于调整目标拍摄参数的取值,例如,响应于用户对参数控制图标的触控操作,生成对应的控制指令,并将该控制指令发送至拍摄设备,以指示拍摄设备基于该控制指令调整目标拍摄参数的取值。通过在确定目标拍摄参数的取值范围后,同步的基于确定的取值范围调整对应的参数控制图标,便于用户通过参数控制图标调整目标拍摄参数的取值。
在一实施例中,在确定目标拍摄参数的取值范围后,将目标拍摄参数的取值范围发送至与云台连接的终端设备,以供终端设备根据目标拍摄参数的取值范围,调整终端设备当前显示的参数控制图标。通过在确定目标拍摄参数的取值范围后,同步的基于确定的取值范围调整终端设备显示的对应参数控制图标,便于用户通过参数控制图标调整目标拍摄参数的取值。
在一实施例中,根据目标拍摄参数的取值范围,调整显示装置当前显示的参数控制图标的方式可以为:根据该取值范围,调整参数控制图标的大小;和/或根据该取值范围,调整参数控制图标上的目标拍摄参数的取值范围对应的数值。其中,目标拍摄参数的取值范围越大,则参数控制图标的尺寸越大,而目标拍摄参数的取值范围越小,则参数控制图标的尺寸越小,参数控制图标的形状和显示方式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。
上述实施例提供的参数自适应方法,通过向拍摄设备发送多个控制指令,使得拍摄设备将目标拍摄参数的取值配置为控制指令对应的预设取值,然后获取拍摄设备返回的目标拍摄参数的取值的配置结果,并根据配置结果确定目标拍摄参数的取值范围,不需要在开发时尽可能的适配不同厂家、不同系列以及不同型号的拍摄设备,能够实现自适应的调整不同拍摄设备的拍摄参数的取值范围,极大地提高了用户体验。

在一实施例中,获取第一调焦间隔时间,并以第一调焦间隔时间向拍摄设备发送调焦控制指令;获取拍摄设备基于该调焦控制指令返回的调焦控制结果;若该调焦控制结果为拍摄设备调焦失败,则获取第二调焦间隔时间,并以第二调焦间隔时间向拍摄设备发送所述调焦控制指令;若以第二调焦间隔时间发送的调焦控制指令的调焦控制结果为拍摄设备调焦成功,则调高第二调焦间隔时间,以更新第二调焦间隔时间,之后以更新后的第二调焦间隔时间向拍摄设备发送调焦控制指令;若以第二调焦间隔时间发送的调焦控制指令的调焦控制结果为拍摄设备调焦失败,则停止向拍摄设备发送调焦控制指令。其中,第一调焦间隔时间大于第二调焦间隔时间。通过在以第一调焦间隔时间发送的调焦控制指令的调焦控制结果为调焦失败时,以第二调焦间隔时间发送调焦控制指令,能够提高拍摄设备的调焦校准的精度。
在一实施例中,调高第二调焦间隔时间,以更新第二调焦间隔时间的方式可以为:获取时间变化值,并用第二调焦间隔时间加时间变化值,得到更新后的第二调焦间隔时间。例如,时间变化值为ΔT,第二调焦间隔时间为T 2,则更新后的第二调焦间隔时间为T 2+ΔT。其中,时间变化值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。可以理解的是,时间变化值越小,则拍摄设备的调焦校准的精度越高,而时间变化值越大,则拍摄设备的调焦校准的精度越低。
在一实施例中,获取时间变化值的方式可以为:获取预设百分比,并用第二调焦间隔时间乘以预设百分比,得到时间变化值。例如,时间变化值为ΔT,第二调焦间隔时间为T 2,预设百分比为β,则时间变化值ΔT=T 2*β,因此,更新后的第二调焦间隔时间可以表示为T 2-(T 2*β)。其中,预设百分比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。可以理解的是,预设百分比越小,则拍摄设备的调焦校准的精度越高,而预设百分比越大,则拍摄设备的调焦校准的精度越低。
在一实施例中,调高前的第二调焦间隔时间与调高后的第二调焦间隔时间 之间的比值小于或等于第二预设比值,第二预设比值可基于实际情况进行设置,本申请对此不做具体限定,例如,第二预设比值为0.5。示例性的,调高前的第二调焦间隔时间为4毫秒,调高后的第一调焦间隔时间为8毫秒,调高前的第二调焦间隔时间与调高后的第二调焦间隔时间之间的比值为0.5。

其中,对于每个调焦控制量,存储有拍摄设备返回的以不同调焦间隔时间发送的调焦控制指令的调焦控制结果,即一个调焦间隔时间与一个调焦控制指令的调焦控制结果对应,目标调焦间隔时间包括目标跟焦间隔时间和目标变焦间隔时间中的任一项,目标跟焦间隔时间用于表示云台向拍摄设备发送跟焦控制指令的间隔时间,跟焦控制指令用于指示拍摄设备调整焦平面的移动速度,而目标变焦间隔时间用于表示云台向拍摄设备发送变焦控制指令的间隔时间,变焦控制指令用于指示拍摄设备调整焦平面的移动距离。
在一实施例中,针对每个调焦控制量,获取该调焦控制结果为调焦成功对应的调焦控制指令的多个候选调焦间隔时间;根据每个调焦控制量的多个候选调焦间隔时间,确定每个调焦控制量的目标调焦间隔时间。以单个调焦控制量为例对目标调焦间隔时间的确定进行解释说明,具体为:从多个候选调焦间隔时间中选择最小的候选调焦间隔时间作为调焦控制量的目标调焦间隔时间。
例如,调焦控制量集合包括调焦控制量A、调焦控制量B和调焦控制量C,且发送调焦控制量A对应的调焦控制指令的调焦间隔时间分别为20毫秒、15毫秒、10毫秒、5毫秒、2毫秒和1毫秒,其中,调焦间隔时间为20毫秒、15毫秒、10毫秒、5毫秒和2毫秒发送的调焦控制指令的调焦控制结果为调焦成功,因此,调焦控制量A的多个候选调焦间隔时间为20毫秒、15毫秒、10毫秒、5毫秒和2毫秒,则调焦控制量A的目标调焦间隔时间为2毫秒。
类似的,发送调焦控制量B对应的调焦控制指令的调焦间隔时间分别为25毫秒、20毫秒、15毫秒、10毫秒、5毫秒和2毫秒,其中,25毫秒、20毫秒、15毫秒、10毫秒和5毫秒发送的调焦控制指令的调焦控制结果为调焦成功,因此,调焦控制量B的多个候选调焦间隔时间为25毫秒、20毫秒、15毫秒、10毫秒和5毫秒,则调焦控制量B的目标调焦间隔时间为5毫秒。
类似的,发送调焦控制量C对应的调焦控制指令的调焦间隔时间分别为20毫秒、15毫秒、10毫秒、5毫秒、1毫秒和0.5毫秒,其中,20毫秒、15毫秒、10毫秒、5毫秒和1毫秒发送的调焦控制指令的调焦控制结果为调焦成功,因 此,调焦控制量C的多个候选调焦间隔时间为20毫秒、15毫秒、10毫秒、5毫秒和1毫秒,则调焦控制量C的目标调焦间隔时间为1毫秒。
可以理解的是,调焦校准包括跟焦校准和变焦校准中的任一项,云台可以仅对拍摄设备进行跟焦校准,也可以仅对拍摄设备进行变焦校准,还可以先对拍摄设备进行跟焦校准,之后再对拍摄设备进行变焦校准,还可以先对拍摄设备进行变焦校准,之后再对拍摄设备进行跟焦校准,本申请实施例对此不做具体限定。

在一实施例中,根据调焦校准指令获取拍摄设备的调焦控制量集合的方式可以为:根据调焦校准指令,将预设调焦控制量集合作为拍摄设备的调焦控制量集合。其中,预设调焦控制量集合可以基于不同厂家、不同系列以及不同型号的拍摄设备的调焦控制量集合确定,也即基于不同厂家、不同系列以及不同型号的拍摄设备的调焦控制量集合为预设调焦控制量集合的子集。通过设置一个大范围的调焦控制量集合,在对拍摄设备进行调焦校准时,可以适配不同厂家、不同系列以及不同型号的拍摄设备,从而能够对不同厂家、不同系列以及不同型号的拍摄设备进行调焦校准。
在一实施例中,根据调焦校准指令获取拍摄设备的调焦控制量集合的方式可以为:根据调焦校准指令中的设备标识,获取拍摄设备的调焦控制量集合,即将与调焦校准指令中的设备标识对应的调焦控制量集合作为拍摄设备的调焦控制量集合。其中,设备标识用于表示拍摄设备的厂商、类型和/或型号,不同的设备标识对应不同的调焦控制量集合。通过调焦校准指令中的设备标识获取拍摄设备的调焦控制量集合,使得获取到的拍摄设备的调焦控制量集合更加符合接入云台的拍摄设备的厂商、类型和/或型号,便于后续更加准确地对拍摄设备进行调焦校准。

其中,调焦控制指令携带有调焦控制量,不同的调焦控制指令携带的调焦控制量不同,调焦控制指令用于指示拍摄设备根据调焦控制指令中的调焦控制量控制焦平面的移动速度或移动距离,调焦控制量集合包括变焦控制量集合和跟焦控制量集合中的任一项,调焦控制量包括变焦控制量和跟焦控制量中的任一项,变焦控制量用于调整拍摄设备的焦平面的移动距离,变焦控制量越大,则焦平面的移动距离的变化速度越快,变焦控制量越小,则焦平面的移动距离的变化速度越慢,跟焦控制量用于调整拍摄设备的焦平面的移动速度,跟焦控 制量越大,则焦平面的移动速度越快,跟焦控制量越小,则焦平面的移动速度越慢。
S303、以不同的调焦间隔时间向所述拍摄设备发送所述调焦控制指令,以供所述拍摄设备基于所述调焦控制指令中的调焦控制量进行调焦控制。
在生成调焦控制指令后,以不同的调焦间隔时间向拍摄设备发送调焦控制指令,拍摄设备在接收到以不同调焦间隔时间发送的调焦控制指令后,基于调焦控制指令中的调焦控制量进行调焦控制,并向云台返回以不同调焦间隔时间发送的调焦控制指令的调焦控制结果。
在一实施例中,如图6所示,步骤S303包括子步骤S3031a至S3034a。

其中,第一调焦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。通过降低调焦间隔时间,使得云台能够以不同的调焦间隔时间向拍摄设备发送调焦控制指令,便于后续基于以不同调焦间隔时间发送的调焦控制指令的调焦控制结果确定调焦控制量的目标调焦间隔时间。
在一实施例中,降低第一调焦间隔时间,以更新第一调焦间隔时间的方式可以为:获取时间变化值,并用第一调焦间隔时间减去时间变化值,得到更新后的第一调焦间隔时间。例如,时间变化值为ΔT,第一调焦间隔时间为T 1,则更新后的第一调焦间隔时间为T 1-ΔT。其中,时间变化值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。可以理解的是,时间变化值越小,则拍摄设备的调焦校准的精度越高,而时间变化值越大,则拍摄设备的调焦校准的精度越低。
在一实施例中,获取时间变化值的方式可以为:获取预设百分比,并用第一调焦间隔时间乘以预设百分比,得到时间变化值。例如,时间变化值为ΔT,第一调焦间隔时间为T 1,预设百分比为β,则时间变化值ΔT=T 1*β,因此,更新后的第一调焦间隔时间可以表示为T 1-(T 1*β)。其中,预设百分比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。可以理解的是,预设百分比越 小,则拍摄设备的调焦校准的精度越高,而预设百分比越大,则拍摄设备的调焦校准的精度越低。
