背景技术
随着无人机技术的快速发展，无人机的应用越来越广泛，例如，可以通过无人机实现植保作业。一般在植保作业的过程中，需要通过无人机的遥控器进行打点作业，以规划作业区域，使得无人机可以在作业区域内进行作业。例如，需要用户手持遥控器，围绕作业区域进行打点，此时利用遥控器设置的天线接收卫星信号来设置作业区域。而天线的最佳位置是与地面保持垂直向上，如果天线与地面之间的角度偏差超出了一定角度，会导致天线接收性能变差。由于用户在使用打点功能时会边行走边打点，用户行走过程中的抖动，极容易使天线倾角发生偏移，甚至有的用户倒拿遥控器，大大降低了天线接收信号质量，导致打点到的定位不准或定位失败，使作业区域发生较大偏移，从而作业区域规划的准确降低。

为了方便带动天线旋转，在一些实施方式中，旋转控制器还可以包括用于承载天线的旋转台，舵机组、步进电机组、或伺服电机组等旋转控制器可以通过旋转台与天线连接，以便控制天线旋转。该旋转台可以是任意的电路板等器件，具体类型在此处不作限定。
在一些实施方式中，当旋转控制器为舵机组时，舵机组包括控制天线在第一方向上旋转的第一舵机和控制天线在第二方向上旋转的第二舵机。
为了灵活控制天线旋转，舵机组可以包括多个，例如，舵机组可以包括控制天线在X轴方向上旋转的第一舵机和控制天线在Z轴方向上旋转的第二舵机等。
在一些实施方式中，可移动平台控制方法还可以包括：当确定天线无法调节成与地面之间形成目标位置关系时，输出天线无法调节成与地面之间形成目标位置关系的提示信息。
在控制终端倒立或其他特殊情况下，例如，用户在使用控制终端的打点功 能(即定位功能)时，会手持控制终端边行走边打点，极容易使天线倾角发生偏移，甚至有的用户倒拿控制终端，导致定位不准或定位失败，使作业区域发生偏移。此时，当确定天线无法调节成与地面之间形成目标位置关系(例如仰角为90度的垂直关系)时，输出天线无法调节成与地面之间形成目标位置关系的提示信息，以便用户及时获知，并及时调整手持控制终端的状态。
在一些实施方式中，输出天线无法调节成与地面之间形成目标位置关系的提示信息可以包括：驱动蜂鸣器的鸣响信息指示天线无法调节成与地面之间形成目标位置关系的提示信息；和/或，控制扬声器语音播报天线无法调节成与地面之间形成目标位置关系的提示信息；和/或，通过震动马达的振动信息指示天线无法调节成与地面之间形成目标位置关系的提示信息；和/或，通过指示灯的闪烁信息指示天线无法调节成与地面之间形成目标位置关系的提示信息；和/或，控制显示屏显示天线无法调节成与地面之间形成目标位置关系的提示信息。
例如，为了提高提示信息输出的灵活性，可以驱动控制终端预设的蜂鸣器鸣响预设时间或预设次数，生成鸣响信息，以通过蜂鸣器的鸣响信息指示天线无法调节成与地面之间形成目标位置关系的提示信息，使得在舵机等旋转控制器无法通过旋转天线使其仰角保持在90°时，通过发出鸣响提示用户不要让控制终端倾角过大或翻转等。
又例如，为了提高提示信息输出的准确性，可以控制扬声器通过语音播报天线无法调节成与地面之间形成目标位置关系的提示信息，以便在用户手持控制终端方向错误，导致天线倾角过大或翻转时提示用户，避免定位失败而导致测绘记录失败。
又例如，为了提高提示信息输出的灵活性，可以控制震动马达震动，通过震动马达的振动信息指示天线无法调节成与地面之间形成目标位置关系的提示信息，使得在舵机等旋转控制器无法通过旋转天线使其仰角保持在90°时，通过震动提示用户不要让控制终端倾角过大或翻转等。
又例如，为了提高提示信息输出的便捷性，可以控制指示灯的闪烁，通过指示灯的闪烁信息指示天线无法调节成与地面之间形成目标位置关系的提示信息，以便及时提醒用户不要让控制终端倾角过大或翻转等，以及时通过舵机等旋转控制器旋转天线使其仰角保持在90°。
又例如，为了提高提示信息输出的可靠活性，可以控制显示屏在显示界面内弹窗显示或直接文字显示天线无法调节成与地面之间形成目标位置关系的提 示信息。以便及时提醒用户不要让控制终端倾角过大或翻转等，以及时通过舵机等旋转控制器旋转天线使其仰角保持在90°。
需要说明的是，提示信息的输出方式还可以通过其他任意声、光、或触觉等方面的提示，具体内容在此处不作限定。
S102、基于调节后的天线生成多个定位点。
在一些实施方式中，基于调节后的天线生成多个定位点可以包括：在维持天线与地面之间的目标位置关系的条件下，基于天线在多个位置接收到的定位数据进行定位，生成多个定位点。
控制终端可以在多个位置分别进行定位，以生成多个定位点。例如，控制终端可以在第一位置维持天线与地面之间的目标位置关系的条件下，基于天线接收到的定位数据进行定位，生成第一定位点，以及，在第二位置维持天线与地面之间的目标位置关系的条件下，基于天线接收到的定位数据进行定位，生成第二定位点，以及，在第三位置维持天线与地面之间的目标位置关系的条件下，基于天线接收到的定位数据进行定位，生成第三定位点；等等。其中，定位点可以包括位置信息，该位置信息可以是经纬信息。
在一些实施方式中，基于天线在多个位置接收到的定位数据进行定位，生成多个定位点可以包括：输出对天线调节完成的提示信息；基于提示信息接收用户输入的定位指令，基于定位指令和调节后的天线接收到的定位数据进行定位，生成多个定位点。
为了提高定位的准确性和可靠性，在完成天线的调节后，可以输出天线与地面之间形成目标位置关系的提示信息(即对天线调节完成的提示信息)，以便用户获知天线调节完成，此时，可以在维持天线与地面之间的目标位置关系的条件下，接收用户在第一位置通过控制终端上预设的实体按键、虚拟按键、指纹、手势、语音或滑动等触发操作，生成的第一定位指令，基于第一定位指令和调节后的天线接收到的定位数据进行定位，生成第一定位点。当用户移动在第二位置后，在第二位置完成天线的调节后，可以输出对天线调节完成的提示信息，以便用户获知天线调节完成，此时，可以在维持天线与地面之间的目标位置关系的条件下，接收用户在第二位置通过控制终端上预设的实体按键、虚拟按键、指纹、手势、语音或滑动等触发操作，生成的第二定位指令，基于第二定位指令和调节后的天线接收到的定位数据进行定位，生成第二定位点。以此类推，可以在多个位置基于定位指令和调节后的天线接收到的定位数据进 行定位，生成多个定位点。
需要说明的是，为了确保在维持天线与地面之间的目标位置关系的条件下进行定位，可以在天线与地面之间未形成目标位置关系时，即使接收到用户输入的定位指令，也不会控制天线接收定位数据进行定位，直至天线与地面之间形成目标位置关系时，才会控制天线接收定位数据进行定位。
在一些实施方式中，可移动平台控制方法还可以包括：当天线与地面之间形成的目标位置关系发生变化时，重新控制旋转控制器对天线的姿态进行调节，以维持天线与地面之间的目标位置关系。
为了能够实时调节天线的仰角，有效防止由于用户手持控制终端行走过程中的抖动导致的天线倾斜情况，可以实时检测天线与地面之间形成的目标位置关系是否发生变化，当天线与地面之间形成的目标位置关系发生变化时，重新控制旋转控制器对天线的姿态进行调节，以维持天线与地面之间的目标位置关系。
S103、根据多个定位点确定目标作业区域，控制可移动平台在目标作业区域内进行作业。
在得到多个定位点后，可以根据多个定位点确定目标作业区域，例如，可以对四边形作业区域的四个顶角位置进行定位，得到四个定位点，根据这四个定位点连线生成四边形的目标作业区域。又例如，可以对六边形作业区域的六个顶角位置进行定位，得到六个定位点，根据这六个定位点连线生成六边形的目标作业区域。又例如，可以对三个位置进行定位，得到三个定位点，根据这三个定位点连线生成三角形，并绘制三角形的外接圆，得到圆形的目标作业区域。又例如，可以对九个位置进行定位，得到九个定位点，根据这九个定位点连线生成多边形，并绘制多边形的外接圆或内接圆，得到圆形的目标作业区域。
在确定目标作业区域后，可以控制可移动平台在目标作业区域内进行作业。实现一体化、高可靠性、且实时的天线的自动稳定调节，应用于无人机的遥控器打点作业区域规划等，需要精准定位的场景。例如，以可移动平台为无人机为例，该无人机可以包括可移动主体和喷洒装置，喷洒装置装设于可移动主体上。在一些实施方式中，无人机用于农耕产业中对农产品、林木等进行农药、水等液体喷洒作业活动。例如，可移动主体可以实现移动、转动、以及翻转等动作，可移动主体可以带动喷洒装置运动到不同的位置或者不同的角度以在预设区域内进行喷洒作业。
在一些实施方式中，喷洒装置可以包括供液箱、水泵、喷头和电磁流量计等。示例性的，供液箱内容纳有待喷洒的液体。水泵用于从供液箱内抽取液体。喷头与水泵相连通，水泵向喷头输送液体，并通过喷头将液体喷洒出去，从而进行喷洒作业。
具体的，电磁流量计连通于供液箱和水泵之间。水泵从供液箱内抽取液体时，供液箱内的液体经电磁流量计流至水泵，此时电磁流量计能够检测由供液箱流入水泵内的液体的流量和/或流速。
可以理解的是，水泵以及电磁流量计的数量可以根据实际需求进行设计，例如一个、两个、三个或者更多。各水泵、电磁流量计可以同时工作；也可以根据实际需求选择其中一个或者数个水泵、电磁流量计工作，剩余水泵、电磁流量计不工作。
示例性的，无人机的所有水泵可以一体式设置，也可以是多个独立的水泵并分散在机架的不同位置。无人机的所有电磁流量计可以一体式设置，也可以是多个独立的电磁流量并分散在机架的不同位置。可以理解的，本申请实施例对功能模块的物理位置可以不做具体限制。
以下将以可移动平台为无人机、控制终端为遥控器、天线为RTK/GNSS天线为例进行详细说明，例如，如图3所示，遥控器可以包括控制器、天线、旋转台、舵机组、IMU、震动马达、扬声器、以及蜂鸣器等。
如图4所示，默认情况下，遥控器水平向上放置，此时遥控器绕X轴旋转角度为0°，绕Z轴旋转角度为0°，RTK/GNSS天线方向垂直向上，相对水平位置仰角为90°。
当用户手持遥控器，使用RTK/GNSS天线精准定位功能进行打点，规划作业区域时，对RTK/GNSS天线朝向有较高要求，此时由于用户手持遥控器在行走的同时打点，不可能保持遥控器水平向上放置，因此遥控器处于抖动状态，必然遥控器绕X轴、绕Z轴均有一定的旋转角度，如图5所示。通过控制器接收遥控器内部惯性测量单元IMU的传感器数据，得到遥控器此时绕X轴逆时针旋转A°，绕Z轴逆时针旋转B°。
此时，如图6所示，控制器可以根据遥控器绕X轴以及Z轴的旋转角度，驱动舵机对承载RTK/GNSS天线的旋转台进行旋转，例如，控制舵机1顺时针旋转A°，控制舵机2顺时针旋转B°，使天线仰角实时保持在90°，实时消除由于用户行走过程中的抖动带来的遥控器RTK/GNSS天线倾角改变。可以实现天 线实时自动稳定，消除用户行走过程中带来的遥控器抖动和倾斜，保持RTK/GNSS天线仰角固定在最佳90°，使RTK/GNSS模块定位精度更高，运行更稳定。
当遥控器倾斜角度过大，或遥控器翻转时，此时通过舵机无法使RTK/GNSS天线仰角保持在90°，可以实现用户提示，例如，可以通过控制器驱动蜂鸣器、扬声器、和/或震动马达进行单种或多重提示，提示用户尽量将遥控器保持水平，避免过大倾斜或翻转，防止RTK/GNSS信号质量变差，测量精度下降，甚至失锁无法定位。
具体地，例如，如图7所示，遥控器在空闲状态时，可以判断是否开启天线精准定位功能，若未开启天线精准定位功能(即定位功能)，则维持空闲状态，不需要对天线的姿态进行调节。若开启天线精准定位功能，则通过IMU检测遥控器的倾斜角度，并判断倾斜角度是否小于天线旋转范围。若遥控器的倾斜角度小于天线旋转范围，则通过舵机旋转天线使其保持90度(即90°)仰角，并判断是否继续开启天线精准定位功能，若继续开启天线精准定位功能，则返回执行通过IMU检测遥控器的倾斜角度的操作，若未继续开启天线精准定位功能，则进入空闲状态，不需要对天线的姿态进行调节。若遥控器的倾斜角度不小于天线旋转范围，则通过蜂鸣器、扬声器、和/或震动马达等提示用户遥控器倾斜角过大，以便用户及时调整手持的遥控器。
由于采用了获取遥控器内部IMU数据，驱动舵机旋转旋转台，使RTK/GNSS天线仰角保持在90°，因此可以使用户在手持遥控器使用RTK/GNSS精准定位功能进行打点，规划作业范围时，实时消除行走过程中带来的遥控器抖动，避免由于遥控器倾斜，RTK/GNSS天线仰角变化，导致的信号质量变差，测量精度下降，甚至失锁无法定位。并且，由于在用户手持倾角过大，或者倒拿遥控器，RTK/GNSS天线倾斜过大，无法使用舵机修正天线角度时，采用了包含蜂鸣器、扬声器、震动马达等多种方式对用户进行提示，避免用户错误手持遥控器，导致RTK/GNSS信号质量变差，测量精度下降，甚至失锁无法定位。达到了快速响应、实时性强，高可靠性、低失效概率。
本申请实施例可以基于天线与机体之间的第一位置关系，以及机体与地面之间的第二位置关系，控制旋转控制器对天线的姿态进行调节，以使得天线与地面之间形成目标位置关系；此时，可以基于调节后的天线生成多个定位点，根据多个定位点确定目标作业区域，控制可移动平台在目标作业区域内进行作 业。该方案可以对天线进行自动调节，以维持天线与地面之间形成的目标位置关系，从而可以保证天线接收信号的质量，提高了通过天线定位的准确性和可靠性。
