无人机在作业时,飞手可以通过控制终端对无人机进行远程控制,与无人机距离较远,而地勘人员主要负责跟随无人机,在无人机完成一次作业后,更换无人机的电池、补充农药或者种子等。因此,在无人机作业的过程中或者完成一次作业后,飞手需要与地勘人员进行通话,便于飞手与地勘人员相互协助完成无人机的作业。目前,飞手主要借助对讲机或者手机与地勘人员进行通话,增加了硬件成本,且多个设备的操作和使用较为不便,会影响作业效率。
为解决上述问题,本申请实施例提供一种控制方法、终端、无人机、系统及计算机可读存储介质,该控制方法可以应用于控制终端,也可以应用于无人机,还可以应用于控制系统,本申请实施例对此不做具体限定。请参照图1,图1是实施本申请实施例提供的控制方法的场景示意图,如图1所示,该场景包括控制终端100和无人机200,控制终端100与无人机200通信连接,控制终端100用于控制无人机200,控制终端100设有第一拾音器和第一扬声器,第一拾音器用于采集控制终端100周围环境的环境声音,第一扬声器用于播放音频,无人机200设有第二拾音器和第二扬声器,第二拾音器用于采集无人机200周围环境的环境声音,第二扬声器用于播放音频。其中,第一拾音器和第二拾音器可以为麦克风。
在一实施例中,控制终端100根据第一拾音器采集到的环境声音,生成第一声音文件,若无人机200的旋翼处于静止状态,则将第一声音文件发送至无人机200,无人机200接收控制终端100发送的第一声音文件,并控制第二扬声器播放第一声音文件,使得无人机200附近的地勘人员能够听清楚飞手的喊 话,无人机200根据第二拾音器采集到的环境声音,生成第二声音文件,并将第二声音文件发送至控制终端100,控制终端100接收无人机200发送的第二声音文件,并控制第一扬声器播放第二声音文件,使得控制终端100附近的飞手能够听清楚地勘人员的喊话,从而实现无人机200与控制终端100之间的语音传输,便于飞手与地勘人员之间通过控制终端100与无人机200实现语音对讲,不需要使用对讲机或者手机。
其中,控制终端100包括遥控器、地面控制平台、手机、平板电脑、笔记本电脑和PC电脑等,无人机200可具有一个或多个推进单元,以允许无人机200可在空中飞行。该一个或多个推进单元可使得无人机200以一个或多个、两个或多个、三个或多个、四个或多个、五个或多个、六个或多个自由角度移动。在某些情形下,无人机200可以绕一个、两个、三个或多个旋转轴旋转。旋转轴可彼此垂直。旋转轴在无人机200的整个飞行过程中可维持彼此垂直。旋转轴可包括俯仰轴、横滚轴和/或偏航轴。无人机200可沿一个或多个维度移动。例如,无人机200能够因一个或多个旋翼产生的提升力而向上移动。在某些情形下,无人机200可沿Z轴(可相对无人机200方向向上)、X轴和/或Y轴(可为横向)移动。无人机200可沿彼此垂直的一个、两个或三个轴移动。
无人机200可以是旋翼飞机。在某些情形下,无人机200可以是可包括多个旋翼的多旋翼飞行器。多个旋翼可旋转而为无人机200产生提升力。旋翼可以是推进单元,可使得无人机200在空中自由移动。旋翼可按相同速率旋转和/或可产生相同量的提升力或推力。旋翼可按不同的速率随意地旋转,产生不同量的提升力或推力和/或允许无人机200旋转。在某些情形下,在无人机200上可提供一个、两个、三个、四个、五个、六个、七个、八个、九个、十个或更多个旋翼。这些旋翼可布置成其旋转轴彼此平行。在某些情形下,旋翼的旋转轴可相对于彼此呈任意角度,从而可影响无人机200的运动。

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。该控制方法可以应用在控制终端,该控制终端用于与一无人机通信连接,并用于控制无人机,控制终端设有第一拾音器和第一扬声器,无人机设有第二拾音 器和第二扬声器。
具体地,如图2所示,该控制方法包括步骤S101至步骤S103。
S101、根据所述第一拾音器采集到的环境声音,生成第一声音文件。
在一实施例中,控制终端显示无人机控制界面,其中,该无人机控制界面包括对讲图标;根据用户对该对讲图标的触控操作,控制第一拾音器采集控制终端的环境声音,并对环境声音进行编码,得到第一声音文件。其中,采集到的环境声音可以包括用户的语音,对讲图标在无人机控制界面内的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。通过显示对讲图标,便于用户通过对讲图标启动第一拾音器采集用户的语音,使得控制终端能够基于用户的语音生成声音文件,便于后续发送给无人机。
在一实施例中,根据用户对该对讲图标的触控操作,控制第一拾音器采集控制终端的环境声音的方式可以为:在对讲图标被触控后至对讲图标未被触控前的时间段内,控制第一拾音器采集控制终端的环境声音,即当检测该对讲图标被用户触控时,控制第一拾音器开始采集控制终端的环境声音,然后当检测到该对讲图标未被用户触控时,控制第一拾音器停止采集控制终端的环境声音,并获取第一拾音器已经采集到的环境声音。可以理解的是,在该对讲图标被触控的过程中,若对讲图标被触控的持续时间达到预设时长,则控制第一拾音器停止采集控制终端的环境声音;对第一拾音器已经采集到的环境声音进行编码,得到第一声音文件。其中,预设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,预设时长为60秒。
在一实施例中,当无人机的旋翼处于静止状态时,控制对讲图标处于使能状态,其中,控制终端能够响应用户对处于使能状态的对讲图标的触控操作;当无人机的旋翼处于旋转状态时,控制对讲图标处于关闭状态,其中,控制终端不响应用户对处于关闭状态的对讲图标的触控操作。其中,处于使能状态的对讲图标与处于关闭状态的对讲图标在无人机控制界面上的显示方式不同,例如,处于使能状态的对讲图标与处于关闭状态的对讲图标在无人机控制界面上的位置和/或颜色不同。通过不同的显示方式显示处于关闭状态和处于使能状态的对讲图标,使得用户能够知晓无人机的旋翼的运行状态是静止状态,还是旋转状态,便于位于控制终端附近的用户向位于无人机附近的用户进行喊话,也使得无人机附近的地勘人员能够听清楚位于控制终端附近的用户的喊话。
示例性的,如图3所示,该无人机控制界面包括状态指示栏和对讲图标,该对讲图标处于使能状态,如图4所示,该无人机控制界面显示的对讲图标处 于关闭状态,图3中的对讲图标的颜色与图4中的对讲图标的颜色不同,该状态指示栏内显示有定位模块标识、图传标识、避障模块标识、控制终端连接标识、网络标识和电池标识,通过显示的定位模块标识、图传标识、避障模块标识、控制终端连接标识、网络标识和电池标识可知,无人机是使用GPS定位模块定位的,无人机与控制终端之间的图传正常,避障模块正常工作,无人机与控制终端通信连接正常,控制终端的网络良好、无人机的两块电池的电量分别为80%和100%,且两块电池的工作电压分别为20.7v和26.1v,另外,还可以用预设的不同的颜色标识来标识电池的异常状态和正常状态。
S102、若所述无人机的旋翼处于静止状态,则将所述第一声音文件发送至所述无人机,以供所述无人机控制所述第二扬声器播放所述第一声音文件。
在获取到第一声音文件后,如果无人机的旋翼处于静止状态,则将第一声音文件发送至无人机,无人机接收控制终端发送的第一声音文件,并控制第二扬声器播放接收到的第一声音文件。由于无人机的旋翼处于静止状态,因此无人机周围不存在由于旋翼旋转带来的噪声,使得无人机播放音频时,位于无人机附近的用户能够清楚的听到音频,极大地提高了用户体验。
在一实施例中,无人机的旋翼的运行状态的确定方式可以为:控制终端向无人机请求无人机的旋翼的运行标识,若该运行标识为第一预设标识,则确定无人机的旋翼处于静止状态,若该运行标识为第二预设标识,则确定无人机的旋翼处于旋转状态。其中,旋翼的运行标识用于指示无人机的旋翼的运行状态是静止状态,还是旋转状态,第一预设标识和第二预设标识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,若无人机的旋翼处于旋转状态,则缓存第一声音文件;当确定无人机的旋翼由旋转状态变化为静止状态时,将缓存的第一声音文件发送至无人机。其中,控制终端可以间隔预设时间确定无人机的旋翼是否由旋转状态变化为静止状态,该预设时间可根据实际情况进行设置,本申请实施例对此不做具体限定,例如,预设时间为1秒。通过在无人机的旋翼处于旋转状态时缓存音频,在确定无人机的旋翼由旋转状态变化为静止状态后再将缓存的音频发送给无人机,使得无人机播放音频时,位于无人机附近的用户能够清楚的听到音频,可以极大地提高用户体验。
在一实施例中,当确定无人机的旋翼由旋转状态变化为静止状态时,获取第一声音文件的缓存时长;若第一声音文件的缓存时长小于或等于预设缓存时长,则将缓存的第一声音文件发送至无人机。其中,预设缓存时长可以根据实 际情况进行设置,本申请实施例对此不做具体限定,例如,预设缓存时长为2分钟。通过在无人机的旋翼由旋转状态变化为静止状态,且音频的缓存时长小于设定的缓存时长时,将缓存的音频发送至无人机,使得无人机播放音频时,位于无人机附近的用户能够清楚的听到音频,可以极大地提高用户体验。
在一实施例中,当确定无人机的旋翼由旋转状态变化为静止状态时,获取第一声音文件的缓存时长;若第一声音文件的缓存时长大于预设缓存时长,则输出声音重录制提醒信息,以提醒用户重新录制第一声音文件。通过在无人机的旋翼由旋转状态变化为静止状态,且音频的缓存时长超过设定的缓存时长时,提醒用户重新录制音频,可以保证发送的音频的时效性和准确性。
在一实施例中,输出声音重录制提醒信息的方式可以为:在控制终端的无人机控制界面内显示预设声音重录制提醒文字;和/或控制第一扬声器播放预设声音重录制提醒音;和/或控制该控制终端按照预设振动方式振动,以提醒用户重新录制第一声音文件。其中,预设声音重录制提醒文字、预设声音重录制提醒音和预设振动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,例如,预设声音重录制提醒文字为“请重新录制音频”,预设声音重录制提醒音为急促的滴滴声,预设振动方式为控制该控制终端内的振动器的振动幅度以间隔0.5秒在第一振动幅度与第二振动幅度之间进行切换,第一振动幅度大于第二振动幅度。
在一实施例中,若无人机的旋翼处于旋转状态,则将第一声音文件发送至所述无人机,以供无人机缓存第一声音文件,并当确定无人机的旋翼由旋转状态变化为静止状态时,控制第二扬声器播放缓存的第一声音文件。在无人机的旋翼处于旋转状态时,可以先将音频发送给无人机,由无人机进行缓存,在确定无人机的旋翼由旋转状态变化为静止状态后再播放缓存的音频,使得位于无人机附近的用户能够清楚的听到音频,可以极大地提高用户体验。
S103、获取所述无人机发送的第二声音文件,并控制所述第一扬声器播放所述第二声音文件,其中,所述第二声音文件是根据所述第二拾音器采集到的环境声音生成的。
无人机根据第二拾音器采集到的无人机的环境声音,生成第二声音文件,并将第二声音文件发送至控制终端,控制终端接收无人机发送的第二声音文件,并控制第一扬声器播放第二声音文件。其中,第二声音文件也可以是根据无人机所处环境的背景噪声和第二拾音器采集到的环境声音生成的,无人机所处环境的背景噪声包括无人机所处环境的风声和无人机的螺旋桨或旋翼旋转时所带 来的声音。
上述实施例提供的控制方法,通过控制终端采集其周围环境的环境声音,并基于控制终端周围环境的环境声音生成第一声音文件,然后在无人机的旋翼处于静止状态时,将第一声音文件发送至无人机,由无人机播放第一声音文件,使得无人机附近的地勘人员能够听清楚飞手的喊话。另外,控制终端获取无人机发送的第二声音文件,并播放第二声音文件,使得控制终端附近的飞手能够听清楚地勘人员的喊话,从而实现无人机与控制终端之间的语音传输,便于飞手与地勘人员之间通过控制终端与无人机实现语音对讲。
请参阅图5,图5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。该控制方法应用于无人机,无人机用于与一控制终端通信连接,控制终端设有第一拾音器和第一扬声器,无人机设有第二拾音器和第二扬声器。
如图5所示,该控制方法包括步骤S201至S204。

在一实施例中,无人机包括声音录制控键,无人机响应于用户对该声音录制控键的触发操作,控制第二拾音器采集无人机的环境声音;当该触发操作结束时,根据第二拾音器已经采集到的环境声音,生成第二声音文件。其中,该声音录制控键可以为无人机上的实体控键。由于用户通常是在无人机的旋翼处于静止状态时才会操作该声音录制控键,因此生成的第二声音文件不包括无人机的螺旋桨或旋翼旋转时所带来的声音,使得控制终端播放第二声音文件时,位于控制终端附近的用户能够清楚的听到位于无人机附近的用户的喊话。
例如,该声音录制控键为按钮,当检测该按钮被按压时,控制第二拾音器开始采集无人机的环境声音,当检测到该按钮未被按压时,控制第二拾音器停止采集无人机的环境声音,并根据第二拾音器已经采集到的环境声音,生成第二声音文件,又例如,当检测到用户对该按钮的单击操作时,控制第二拾音器开始采集无人机的环境声音,然后当检测到用户再次对该按钮的单击操作时,控制第二拾音器停止采集无人机的环境声音,并根据第二拾音器已经采集到的环境声音,生成第二声音文件。
在一实施例中,无人机控制显示装置显示声音录制页面,其中,声音录制页面包括声音录制图标;根据用户对声音录制图标的触控操作,控制第二拾音器采集无人机的环境声音,并对环境声音进行编码,得到第二声音文件。其中,可以在无人机的旋翼处于静止状态时,无人机控制显示装置显示声音录制页面, 该声音录制图标在显示装置上的样式和显示方式可基于实际情况进行设置,本申请对此不做具体限定。由于用户通常是在无人机的旋翼处于静止状态时才会操作该声音录制图标,因此生成的第二声音文件不包括无人机的螺旋桨或旋翼旋转时所带来的声音,使得控制终端播放第二声音文件时,位于控制终端附近的用户能够清楚的听到位于无人机附近的用户的喊话。
在一实施例中,根据用户对声音录制图标的触控操作,控制第二拾音器采集无人机的环境声音的方式可以为:在声音录制图标被触控后至未被触控前的时间段内,控制第二拾音器采集无人机的环境声音,即当检测该声音录制图标被用户触控时,控制第二拾音器开始采集无人机的环境声音,然后当检测到该声音录制图标未被用户触控时,控制第二拾音器停止采集无人机的环境声音,并获取第二拾音器已经采集到的环境声音。可以理解的是,在该声音录制图标被触控的过程中,若声音录制图标被触控的持续时间达到预设时长,则控制第二拾音器停止采集无人机的环境声音;对第二拾音器已经采集到的环境声音进行编码,得到第二声音文件。其中,预设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,预设时长为60秒。
在一实施例中,根据第二拾音器采集到的无人机的环境声音,生成第二声音文件的方式可以为:若接收到控制终端发送的声音回传指令,且无人机的旋翼处于静止状态,则根据该声音回传指令控制第二拾音器采集无人机的环境声音;对环境声音进行编码,得到第二声音文件。其中,控制终端显示的无人机控制界面包括声音回传图标,当检测到该声音回传图标被触控时,触发声音回传指令,并将该声音回传指令发送至无人机。示例性的,如图6所示,声音回传图标显示在无人机控制界面的左下角。
在一实施例中,根据该声音回传指令控制第二拾音器采集无人机的环境声音的方式可以为:从该声音回传指令中获取目标采集持续时间,并控制第二拾音器采集无人机的环境声音,直到该环境声音的采集持续时间达到目标采集持续时间。其中,该目标采集持续时间与该声音回传图标的触控持续时间有关,具体为该目标采集持续时间等于该声音回传图标的触控持续时间。在另一实施例中,也可以控制第二拾音器采集无人机的环境声音,直到该环境声音的采集持续时间达到预设持续时间。
在一实施例中,当无人机的旋翼处于静止状态时,控制声音回传图标处于使能状态,其中,控制终端能够响应用户对处于使能状态的声音回传图标的触控操作;当无人机的旋翼处于旋转状态时,控制声音回传图标处于关闭状态, 其中,控制终端不响应用户对处于关闭状态的声音回传图标的触控操作。其中,处于使能状态的声音回传图标与处于关闭状态的声音回传图标在无人机控制界面上的显示方式不同,例如,处于使能状态的声音回传图标与处于关闭状态的声音回传图标在无人机控制界面上的位置和/或颜色不同。通过不同的显示方式显示处于关闭状态和处于使能状态的声音回传图标,使得用户能够知晓无人机的旋翼的运行状态是静止状态,还是旋转状态,便于位于控制终端附近的用户向位于无人机附近的用户进行喊话,也使得无人机附近的地勘人员能够听清楚位于控制终端附近的用户的喊话。
在一实施例中,若接收到控制终端发送的声音回传指令,且无人机的旋翼处于旋转状态,则根据声音回传指令控制第二拾音器采集无人机的环境声音;获取无人机所处环境的背景噪声,并根据所述背景噪声和所述第二拾音器采集到的环境声音,生成第二声音文件,即从第二拾音器采集到的环境声音中过滤背景噪声,得到目标环境声音,并对目标环境声音进行编码,得到所述第二声音文件。其中,背景噪声是通过第二拾音器在无人机的旋翼处于旋转状态时所采集到的,不包含用户的语音,背景噪声包括无人机所处环境的风声和无人机的螺旋桨或旋翼旋转时所带来的声音。由于无人机的旋翼处于旋转状态,在采集到的环境声音中存在无人机的螺旋桨或旋翼旋转时所带来的噪声,通过背景噪声和环境声音,可以生成不带无人机的螺旋桨或旋翼旋转时所带来的噪声的音频,使得后续控制终端播放音频时,控制终端附近的用户能够听清楚位于无人机附近的用户的喊话。

S204、若所述无人机的旋翼处于静止状态,则控制所述第二扬声器播放所述第一声音文件。
若无人机的旋翼处于静止状态,则控制第二扬声器播放第一声音文件。由于无人机的旋翼处于静止状态,因此无人机周围不存在由于旋翼旋转带来的噪声,使得无人机播放音频时,位于无人机附近的用户能够清楚的听到音频,极大地提高了用户体验。
在一实施例中,若无人机的旋翼处于旋转状态,则缓存第一声音文件;当确定无人机的旋翼由旋转状态变化为静止状态时,控制第二扬声器播放缓存的第一声音文件。通过在无人机的旋翼处于旋转状态时,无人机缓存音频,在确定无人机的旋翼由旋转状态变化为静止状态后再播放缓存的音频,使得位于无人机附近的用户能够清楚的听到音频,可以极大地提高用户体验。
