例如,当测距装置10为TOF测距传感器时,发射单元13朝被摄物体发射光脉冲,接收单元14接收由被摄物体反射的光脉冲,测距装置10分别记录发射单元13发射光脉冲的时间及接收单元14接收到光脉冲的时间,以根据发射光脉冲的时间、接收到光脉冲的时间、及光速获取测距装置10与被摄物体之间的实时距离信息。
再例如,当测距装置10为超声波测距传感器时,发射单元13朝被摄物体发射超声波信号,接收单元14接收由被摄物体反射的超声波信号,测距装置10分别记录发射单元13发射超声波信号的时间及接收单元14接收到超声波信号的时间,以根据发射超声波信号的时间、接收到超声波信号的时间、及声速获取测距装置10与被摄物体之间的实时距离信息。
请结合图5,其中,发射单元13的光轴OO1与水平面H之间设有预设夹角α, 以使得发射单元13的光轴的延长线与拍摄装置400的光轴OO2的延长线在预设位置交叉,即确保拍摄装置400的拍摄区域与测距装置10的检测区域能够部分重合,使拍摄区域内的被摄物体能够被测距装置10检测到。预设夹角可以是1°到30°度之间的任意值,例如,预设夹角为1°、2°、3°、4°、5°、6°、7°、8°、9°、10°、11°、14°、15°、16°、17°、18°、19°、20°、21°、23°、25°、28°、29°、30°等,在此不一一列举。预设位置可以是距离拍摄装置400的2米、3米、4米、5米、6米等的位置处。
请参阅图1,测距装置10可以安装在拍摄装置400的顶部、任一侧面或底部,只需确保发射单元13的光轴与水平面之间设有预设夹角即可。通常地,在拍摄装置400的顶部设有用于连接其他设备的热靴或冷靴,测距装置10能够安装在拍摄装置400的顶部并与拍摄装置400的热靴或冷靴连接。测距装置10也可以配合夹持结构使用夹持在拍摄装置400的顶部、任一侧面或底部。
请参阅图3及图4,在某些实施方式中,测距装置10还可包括控制键15。控制键15可以位于测距装置10的顶部、底部或任一侧面。控制键15用于根据第一操作控制驱动装置200进入校准模式以及根据第二操作切换驱动装置200的工作模式,工作模式包括第一工作模式和第二工作模式。
当驱动装置200在第一工作模式时,驱动装置200用于根据实时距离信息驱动拍摄装置400的镜头410运动以自动对焦和/或自动变焦,此时,驱动装置200不依赖控制装置300的控制,而是自动根据实时距离信息来驱动拍摄装置400的镜头410运动。
当驱动装置200在第二工作模式时,驱动装置200根据控制装置300的控制驱动拍摄装置400的镜头410运动以手动对焦和/或手动变焦,此时,驱动装置200不再根据实时距离信息驱动拍摄装置400的镜头410运动,而是响应用户对控制装置300的操作。
其中,控制键15包括按钮、旋钮、滑动开关、虚拟触摸键中的任意一种。以控制键为按钮为例,第一操作可以是双击按钮,第二操作可以是单击按钮。在进行第一操作后,能够主动控制驱动装置200进入校准模式,在校准模式下可以根据拍摄装置400当前配置的镜头410的焦距或焦段校准驱动装置200,使驱动装置200适配拍摄装置400当前配置的镜头410。在进行第二操作后,能够切换驱动装置200的工作模式,例如从第一工作模式切换至第二工作模式,或从第二工作模式切换至第一工作模式,以根据需求自动或手动控制驱动装置200,以实现自动或手动对焦和/或变焦。
请参阅图3及图4,在某些实施方式中,测距装置10还可包括指示单元16。指示单元16可以位于测距装置10的顶部、底部或任一侧面。指示单元16用于指示驱 动装置200的当前状态,即用于指示第一工作模式、第二工作模式、或待标定模式中的任意一种。
其中,待标定模式包括指示驱动装置200未进入校准模式。在一个实施例中,当需要使用驱动装置200驱动拍摄装置400的镜头410运动以对焦和/或变焦时,需要先进行标定操作,此时指示单元16指示驱动装置200当前处于待标定模式。若驱动装置200在进行标定前没有被校准,则可以通过对控制键15进行第一操作使驱动装置200进入校准模式以校准驱动装置200,或者驱动装置200自动进入校准模式。当驱动装置200已校准时,可以进行标定操作。在标定时,需要使驱动装置200控制镜头410在至少两个对焦标定点完成合焦,从而完成测距装置10或拍摄装置400与被摄目标之间的实时距离信息与驱动装置200的驱动电机210转动位置的映射关系的标定。在完成标定后,驱动装置200的工作模式自动切换为第一工作模式或第二工作模式,或者手动将驱动装置200的工作模式自动切换为第一工作模式或第二工作模式,此时指示单元16对应地指示驱动装置200的当前状态。
在一个实施例中,指示单元16为显示屏,显示屏能够通过文字和/或图像指示驱动装置200的当前状态。此时,指示单元16可以安装在测距装置10的顶部或任一侧面。
在另一个实施例中,指示单元16为声音提示器,例如扬声器,声音提示器能够通过语音播报指示驱动装置200的当前状态。此时,指示单元16可以安装在测距装置10的顶部、底部或任一侧面。
在再一个实施例中,指示单元16为指示灯,指示灯通过指示灯的颜色和/或指示灯的闪烁规律(例如闪烁频率)指示驱动装置200的当前状态。例如指示灯能够保持绿灯常亮以指示驱动装置200在第一工作模式,指示灯能够保持黄灯常亮以指示驱动装置200在第二工作模式,指示灯能够保持红灯常亮以指示驱动装置200在待标定模式。当需要使用驱动装置200驱动拍摄装置400的镜头410运动以对焦和/或变焦时,若没有进行过标定,则指示灯保持红灯常亮。当标定完成后,指示灯根据驱动装置200的当前状态由红灯常亮变为黄灯常亮或绿灯常亮。当驱动装置200由第一工作模式变为第二工作模式时,指示灯由绿灯常亮变为黄灯常亮。当驱动装置200由第二工作模式变为第一工作模式时,指示灯由黄灯常亮变为绿灯常亮。当然,这里仅仅是以黄灯、绿灯、红灯为示例区分指示第一工作模式、第二工作模式、和待标定模式,实际可以采用其他的不同颜色来区分指示第一工作模式、第二工作模式、和待标定模式,只要三种模式对应的颜色彼此不同即可。
请参阅图1,在某些实施方式中,拍摄辅助结构100还可包括第一传输件20及第 二传输件30。请结合图3及图4,第一传输件20电连接第一接口11与驱动装置200,第一传输件20用于传输实时距离信息至驱动装置200。

在另一个实施例中,第二传输件30包括无线传输模块,例如第二传输件30包括蓝牙模块、WiFi模块以及LiFi模块中的任意一种,在此不做限制。第二传输件30能够将操作控制装置300产生的控制信号传输至测距装置10,再由测距装置10将该控制信号传输至驱动装置200,以通过操作控制装置300使驱动装置200驱动镜头410运动实现手动对焦和/或手动变焦。当第二传输件30包括无线传输模块时,第二传输件30能够将控制信号以无线信号的方式传输至测距装置10,再由测距装置10通过第一传输件20将该控制信号传输至驱动装置200,控制装置300可以更加灵活地设置在不同位置处,避免复杂的接线连接。
请参阅图1,在某些实施方式中,第二接口12可用于与云台500电连接。控制装置300和拍摄装置400均安装在云台500上,驱动装置200也可以安装在云台500上。云台500用于对拍摄装置400进行增稳,以确保拍摄画面稳定不晃动。云台500还用于拍摄角度的调节,即能够通过云台500调节安装在云台500上的拍摄装置400的拍摄角度,使拍摄装置400的镜头410能够对准目标拍摄位置。控制装置300与云台500电连接,使用户操作控制装置300产生的控制信号能够依次经由云台500、第二传输件30、第二接口12、测距装置10、第一接口11、及第一传输件20传输至驱动装置200,使用户能直接在云台500上操作控制装置300手动对焦和/或手动变焦。
在某些实施方式中,第二接口12可以与云台500的遥控设备(图未示出)电连接,控制装置300安装在遥控设备上。云台500的遥控设备可以是控制云台500的遥控器,还可以是设有能够控制云台500的应用程序的手机、笔记本电脑、平板电脑等数码产品。在一些拍摄场景中,当拍摄装置400和装有拍摄装置400的云台500的位置距离用户较远时,可以通过操作遥控设备在距离云台500较远的位置处控制云台500调整拍摄装置400的拍摄角度,还可以通过操作云台500的遥控设备上的控制装置300在距离云台500较远的位置处进行手动对焦和/或手动变焦。
请参阅图3,在某些实施方式中,拍摄辅助结构100还包括安装组件40a。请结合图6,安装组件40a包括连接部件40,连接部件40用于将测距装置10与待连接部件50连接。
连接部件40可包括结合件41、压紧件43、及锁紧件45。
结合件41的一端与测距装置10抵接,结合件41的另一端与待连接部件50连接。结合件41的第一侧411设有凸台415,凸台415的侧面为斜面,用于与待连接部件50抵接,以防止测距装置10相对于待连接部件50旋转。在一个实施例中,待连接部件50具有燕尾槽结构,结合件41的一部分伸入到燕尾槽中,与燕尾槽卡合。进一步地,燕尾槽的内壁可设有斜面,凸台415侧面的斜面与燕尾槽内壁的斜面抵接,以防止测距装置10相对于待连接部件50旋转。
压紧件43安装在结合件41的第一侧411,锁紧件45自结合件41的第二侧413安装在结合件41中,并从结合件41的第一侧411穿出而与测距装置10可拆卸连接。压紧件43能够相对结合件41转动,以调节与待连接部件50之间的抵触力的大小,使压紧件43与待连接部件50之间具有较大的抵触力,使结合件41无法相对待连接部件50移动,以使连接部件40牢固地安装在待连接部件50上。相反地,压紧件43能够相对结合件41转动(与加大抵触力采用的转动反向相反),可使压紧件43与待连接部件50之间的抵触力减小,使结合件41能够相对待连接部件50移动,以便于 调整连接部件40相对待连接部件50的位置或拆卸连接部件40。
当需要将连接部件40从待连接部件50上拆卸时,只需以减小压紧件43与待连接部件50之间的抵触力,使结合件41能够相对待连接部件50移动,再解除结合件41与待连接部件50的抵接,即可实现连接部件40的快速拆卸。当需要将连接部件40安装在待连接部件50上时,只需使结合件41与待连接部件50抵接,再增大压紧件43与待连接部件50之间的抵触力,使结合件41无法相对待连接部件50移动,即可实现连接部件40的快速安装。
在一个实施例中,待连接部件50可以是拍摄装置400。换句话说,拍摄装置400上设置燕尾槽结构(冷靴结构),连接部件40可以直接安装在拍摄装置400上,例如连接部件40可以直接安装在拍摄装置400的热靴结构或冷靴结构上。此时,拍摄辅助结构100可适用于可设置冷靴结构的拍摄装置。
在另一个实施例中,请参阅图3及图6,待连接部件50包括安装件51及紧固件53。安装件51的第一端511与连接部件40连接,紧固件53部分收容在安装件51中,并穿设安装件51的第二端513以与拍摄装置400锁紧。例如,安装件51的第一端511设有燕尾槽,拍摄装置400上设有螺纹结构,紧固件53为螺钉。连接部件40中的结合件41与燕尾槽卡合,再由压紧件43压紧,以实现连接部件40与待连接部件50的固定连接。螺钉部分收容在安装件51中,螺钉的螺杆穿设安装件51的第二端513并与拍摄装置400上的螺纹结构配合,通过锁紧螺钉实现待连接部件50与拍摄装置400的固定连接。此时,拍摄辅助结构100可适用于没有设置冷靴结构的拍摄装置,拍摄装置只需设计预留的螺纹孔与紧固件53连接即可。
请参阅图1,本申请还提供一种拍摄设备1000。拍摄设备1000包括上述任一实施方式的拍摄辅助结构100及驱动装置200。驱动装置200与拍摄辅助结构100电连接,在获取到所述实时距离信息时,驱动装置200能够驱动拍摄装置400的镜头410运动以自动对焦和/或自动变。也就是说,驱动装置200可用于根据实时距离信息驱动拍摄装置400的镜头410运动以自动对焦和/或自动变焦。
在一个实施例中,驱动装置200包括处理器、驱动电机210、和安装在所述驱动电机210上的驱动齿轮220。拍摄装置400的镜头410的外周壁上套设有跟焦环420,跟焦环420上设置有多个齿,驱动齿轮220上的齿与跟焦环420上的齿啮合,驱动齿轮220转动能够带动跟焦环420转动,从而带动与跟焦环420固定连接的镜头410转动从而实现对焦或变焦。实时距离信息可以是测距装置10感测的与距离相关的感测数据,也可以是测距装置10根据其自身感测的与距离相关的感测数据计算出的实时距离值。当实时距离信息为实时距离值时,驱动装置200的处理器能够根据被摄物体 与测距装置10之间的实时距离信息直接计算出驱动电机210的实时输出力矩。当实时距离信息为感测数据时,驱动装置200的处理器先根据感测数据计算出拍摄装置400与测距装置10之间的实时距离值,再根据该实时距离值计算出驱动电机210的实时输出力矩。无论是采用上述哪种方式获得实时输出力矩,驱动装置200的处理器都能够控制驱动电机210以实时输出力矩带动驱动齿轮220转动,使驱动齿轮220带动跟焦环420转动,以带动与跟焦环420固定连接的镜头410转动,从而实现拍摄装置400的自动对焦和/或自动变焦。如此,不仅能够节省人力,通过测距装置10获取的被摄物体与拍摄装置400之间的实时距离信息更加准确,使对焦和/或变焦的调节更加准确,进而拍摄的图像更加清晰。
在某些实施方式中,拍摄设备1000还可包括控制装置300。控制装置300与拍摄辅助结构100电连接,在控制装置300***作时,驱动装置200驱动拍摄装置400的镜头410运动以手动对焦和/或手动变焦。
在一个实施例中,控制装置300可以是拨轮、旋钮、滑动开关、虚拟触摸键中的任意一种。控制装置300被用户操作后产生控制信号,该控制信号能够通过第二接口12传输至测距装置10,再由第一接口11传输至驱动装置200,使驱动装置200能够根据用户操作控制装置300产生的控制信号控制拍摄装置400的镜头410运动以手动对焦和/或手动变焦。手动对焦和/或手动变焦能够在自动对焦和/或自动变焦无法选取到目标对焦点时人为地选取目标对焦点,使对焦和/或变焦的位置符合用户的预期,避免镜头410没有对焦和/或变焦到预期的位置导致拍摄的图像清晰度较低。
在某些实施方式中,拍摄设备1000还可包括云台500,驱动装置200安装在云台500的轴臂510上,控制装置300安装在云台500的支撑机构520或任意轴臂510上,测距装置10安装在拍摄装置400或云台500的轴臂510上。云台500用于对拍摄装置400进行增稳及对拍摄角度的调节。其中,云台500的支撑机构520包括云台500的手持部。
云台500可以是单轴云台,双轴云台、三轴云台、四轴云台等,在此不做限定。在一个实施例中,云台500为三轴云台,测距装置10可以安装在云台500航向轴的轴臂510上,驱动装置200可以安装在云台500横滚轴的轴臂510上,控制装置300可以安装在云台500俯仰轴的轴臂510上。
在一个实施例中,云台500包括电源600,电源600能够通过拍摄辅助结构100的第二传输件30为测距装置10和/或驱动装置200供电。具体地,电源600能够通过第二传输件30直接为测距装置10供电。电源600还能够通过第二传输件30为测距装置10供电,再由测距装置10通过第一传输件20为驱动装置200供电,即电源600 间接为驱动装置200供电。
本申请提供的拍摄设备1000能够适配不同型号的拍摄装置400,通过测距装置10检测被摄物体与测距装置10之间的实时距离信息,并将该实时距离信息传输至驱动装置200,使驱动装置200根据实时距离信息驱动拍摄装置400的镜头410运动以自动对焦和/或自动变焦,不仅能节省人力,还能使对焦和/或变焦更加准确,以使拍摄的图像更加清晰。本申请的拍摄辅助结构100还能够根据用户对控制装置300的操作实现驱动装置200对镜头410的手动对焦和/或手动变焦,以在自动对焦和/或自动变焦的效果不符合预期时能够手动对焦和/或手动变焦。
