现有机制中,主要采用2.4吉赫(英文全称:Gigahertz,英文简称:GHz)传输技术、控制器局域网络(英文全称:Controller Area Network,英文简称:CAN)总线传输技术,其中,2.4GHz传输技术用于控制距离在100米以内的场景,CAN总线传输技术用于控制距离在2米以内的场景。这两种传输技术虽然能实现跟焦场景的多样化,但在超出控制距离之外的范围或干扰较强的区域,连接不稳定或容易出现断开等情况,导致遥控器便无法继续执行跟焦操作,由此可见,现有的机制实际控制距离较短,不能实现远距离跟焦。

本发明实施例提供了一种跟焦控制的方法、相关装置及系统,主要用于航拍、远距拍摄、电影拍摄等场景。以下对本文中所出现的技术名词进行详细说明。
本文中的跟焦拍摄系统主要包括跟焦装置、第一控制装置和移动设备。
其中,跟焦装置用于控制移动设备所搭载的拍摄装置的拍摄焦点,即对拍摄装置跟焦,跟焦装置包括控制端和执行端,控制端主要用于向执行端发送操作指令,执行端则与拍摄装置机械联动,执行端通过执行来自控制端的操作指令以调整拍着装置的焦点,操作指令包括对焦、追焦、变焦等,通过对拍摄装置跟焦,提高拍摄质量和达到特定拍摄效果。
第一控制装置可用于控制移动设备执行移动、拍摄等操作,例如移动设备为搭载相机的无人机时,远程控制无人机飞行、航拍等,第一控制装置还可以用于在跟焦装置远距跟焦时,将跟焦装置的控制端发出的操作指令转发至搭载于移动设备的跟焦装置的执行端,实现跟焦装置的远程跟焦。第一控制装置可以内部集成无线收发装置,也可以与无线收发装置通信连接,共同实现高速、远距传输跟焦装置的控制端的操作指令,在满足高清图传的同时,实现跟焦装置的远程跟焦。
移动设备搭载拍摄装置,移动设备可以为无人机、机器人、玩具车等可在地面端、水中移动或飞行、搭载了拍摄装置,且可以在天空端或地面端或水中等场景的近距离、远距离遥控的任意设备,具体本文中不作限定。
例如移动设备安装于手持云台时,可以采用无线控制局域网络(英文全称:Controller Area Network,英文简称:CAN)连接方式实现跟焦,例如拍摄电影时,跟焦装置可以与第一控制装置无线连接,方便操作跟焦装置的人员,以及操作摄像机的人员互相配合拍摄。又例如,无人机航拍时,控制端可通过第一控制装置中的LB2模块将操作指令发送至执行端,实现远程跟焦,同时,由于在第一控制装置和移动设备之间配备LB2,使得拍摄得到的数据传输时延更小,图像帧更流畅,提高用户的观看体验,尤其适用于如比赛、表演等场景。
为解决现有机制中无法实现远距跟焦的问题,本发明主要提供以下技术方案:
1、跟焦装置与控制移动设备的第一控制装置通信连接,第一控制装置集成无线收发装置,或第一控制装置结合无线收发装置形成无线通信链路。
其中,无线收发装置的一端与地面端的第一控制装置通信连接,另一端则安装于移动设备上,与控制移动设备的第二控制装置通信连接。
2、第一控制装置作为中继设备,实现转发跟焦装置的操作指令至移动设备端的跟焦装置的执行端,使得跟焦装置的执行端调整拍摄装置的拍摄焦点没事闲远程跟焦。
请参照图1和图2,以下对本发明实施例中的一种跟焦控制的方法进行描述,本发明实施例包括:
101、跟焦装置、第一控制装置与移动设备三者建立无线通信链路。
其中,无线通信链路包括以下链路:跟焦装置与第一控制装置通信连接的链路、第一控制装置与移动设备无线通信连接的链路。
跟焦装置可以通过第一控制装置对频实现通信连接,也可以通过有线连接,还可以通过其它的无线连接方式等,具体的连接方式不作限定性。实际应用时,所述跟焦装置的控制端与所述第一控制装置通信连接。
第一控制装置与移动设备可以通过对频实现无线连接,也可以通过有线连接,还可以通过其它的无线连接方式等,具体的连接方式不作限定性。

二、2.4G通信链路

举例来说,在启用上述图4-2中的2.4G通信链路时,跟焦装置的控制端通过第一控制装置转发操作指令时,若该2.4G通信链路失效,则跟焦装置的控制端可以切换至现有的2.4G通信链路实现跟焦,即不通过第一控制装置转发操作指令,直接通过与安装在移动设备的2.4G接收机通信,实现通信链路备份和实时跟焦。
