具体实施方式
下面将结合实施例和实施例中的附图,对本公开技术方案进行清楚、完整的描述。显然,所描述的实施例仅仅是本公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。在下面的详细描述中,为便于解释,阐述了许多具体的细节以提供对本公开实施例的全面理解。然而,明显地,一个或多个实施例在没有这些具体细节的情况下也可以被实施。此外,在以下说明中,省略了对公知结构和技术的描述,以避免不必要地混淆本公开的概念。
附图中示出了一些方框图和/或流程图。应理解,方框图和/或流程图中的一些方框或其组合可以由计算机程序指令来实现。这些计算机程序指令可以提供给通用计算机、专用计算机或其他可编程数据处理装置的处理器,从而这些指令在由该处理器执行时可以创建用于实现这些方框图和/或流程图中所说明的功能/操作的装置。本公开的技术可以硬件和/或软件(包括固件、微代码等)的形式来实现。另外,本公开的技术可以采取存储有指令的计算机可读存储介质上的计算机程序产品的形式,该计算机程序产品可供指令执行系统使用或者结合指令执行系统使用。
农业无人机变量作业的处方图是由一个个面积一定的栅格组成,每个 栅格的颜色表示该栅格所需要的单位面积用量或该栅格所需要的总用量。
在变量作业过程中,农业无人机确定当前时刻的位置处于某个栅格中,根据当前栅格对应的用量计算流量,并确定农业无人机当前的作业指令。
但在实现本公开的过程中发现,农业无人机处于栅格中的位置可能位于栅格的中心,也可能位于栅格的边缘,农业无人机的喷幅和拨幅所覆盖的区域可能包含邻近的多个栅格,使得与农业无人机当前所处栅格邻近的多个栅格也会被喷洒播撒,导致根据农业无人机当前位置计算的流量并非是农业无人机喷洒播撒覆盖范围内的实际需求,进而导致农业无人机变量作业的用量不精确,该问题是变量作业领域内长期存在的问题。
由此可见,当前的变量作业的实时用量值是根据农业无人机当前位置与处方图上的栅格相对应,该栅格表示的用量即为当前时刻农业无人机的用量。但是在大多数情况下,处方图上栅格的划分与农业无人机的航迹并不相匹配,农业无人机在任意时刻可能处于某个栅格的边缘处,若栅格面积划分较小,且邻近几个栅格(作业范围内)与当前栅格内的所需亩用量相差较大,就会导致农业无人机以当前栅格内的亩用量为基准进行变量作业,周围几个栅格区域内会出现漏喷/过喷的问题,无法实现较为精准的变量作业。
本公开的实施例提供了一种农业无人机的作业控制方法,包括:获取上述农业无人机当前的位置信息;根据上述农业无人机当前的位置信息确定上述农业无人机的作业覆盖区域;从上述农业无人机的作业覆盖区域中确定多个目标子区域,其中,每个上述目标子区域具有对应的预设物料投放量;以及根据多个上述目标子区域中每个上述目标子区域各自对应的预设物料投放量,确定与上述农业无人机当前的位置信息相匹配的实际物料投放量。
本公开的实施例可以较为精准地计算实际物料投放量,以控制农业无人机进行变量作业。以下对农业无人机的作业控制方法及装置的应用场景进行说明。
图1示意性示出了根据本公开实施例的可以应用农业无人机的作业控制方法及装置的应用场景。需要注意的是,图1所示仅为可以应用本公开实施例的场景的示例,以帮助本领域技术人员理解本公开的技术内容,但 并不意味着本公开实施例不可以用于其他设备、系统、环境或场景。
如图1所示,农业无人机101可以在一片林地或耕地上进行变量作业。,可以预先获得该林地或耕地的处方图。农用无人机101具有机动性强、作业效率高、成本低、环境适应强等特点,在农作物施药、施肥、授粉和农田监测等领域都可以应用。
根据本公开的实施例,农业无人机101可以进行各种类型的变量作业。如图1所示,农业无人机101可以向林地或耕地上喷洒液体102,或者播撒固体以及粉状物等等。根据本公开的实施例,变量作业包括但不限于喷洒杀虫剂、杀菌剂、除草剂以及催熟脱叶剂、增糖剂、肥料等添加物的喷洒作业,也包括对固体种子,粉末物的播撒作业。
根据本公开的实施例,农业无人机101可以获取农业无人机101当前的位置信息;根据农业无人机101当前的位置信息确定农业无人机101的作业覆盖区域;从农业无人机101的作业覆盖区域中确定多个目标子区域;以及根据多个目标子区域中每个目标子区域各自对应的预设物料投放量,确定与农业无人机101当前的位置信息相匹配的实际物料投放量。
根据本公开的实施例,可支持变量作业的农业无人机101能够通过处方图实时获取多个目标子区域的用量信息,进而依据多个目标子区域的用量信息计算得出当前的喷洒/播撒流量,并将指令下发给农业无人机101对应的执行机构完成植保作业。根据本公开的实施例,目标子区域可以为处方图上的一个或多个栅格。
根据本公开的实施例,根据多个目标子区域中每个目标子区域各自对应的预设物料投放量,确定与农业无人机当前的位置信息相匹配的实际物料投放量,保证了处方图上作业区域栅格内的用量的精确性,避免了由于当前栅格与邻近栅格的用量相差较大而导致的变量作业漏喷或过喷的问题,有效提升了变量作业的精度,保证了变量作业的作业效果。
图2示意性示出了根据本公开实施例的农业无人机的作业控制方法的流程图。
需要说明的是,本公开实施例中的流程图所示的操作除非明确说明不同操作之间存在执行的先后顺序,或者不同操作在技术实现上存在执行的先后顺序,否则,多个操作之间的执行顺序可以不分先后,多个操作也可 以同时执行。
如图2所示,该农业无人机的作业控制方法包括操作S201~S204。
在操作S201,获取农业无人机当前的位置信息。
根据本公开的实施例,例如,可以利用农业无人机上的定位装置获取农业无人机当前的位置信息。定位装置包括但不限于GPS定位装置、超声传感器等等。
在操作S202,根据农业无人机当前的位置信息确定农业无人机的作业覆盖区域。
根据本公开的实施例,可以以农业无人机当前的位置信息为参考位置,将农业无人机的喷洒系统所能覆盖的区域作为农业无人机的作业覆盖区域。根据本公开的实施例,农业无人机的喷洒系统可以设置在机翼或者机身底部等位置。
根据本公开的实施例,可以以农业无人机当前的位置信息为参考位置,根据喷洒系统的喷幅宽度确定农业无人机的作业覆盖区域。
根据本公开的实施例,作业覆盖区域的形状不做限定,例如,可以是矩形,圆形等等。
在操作S203,从农业无人机的作业覆盖区域中确定多个目标子区域,其中,每个目标子区域具有对应的预设物料投放量。
根据本公开的实施例,作业覆盖区域可以包括多个子区域,每个子区域在处方图上具有对应的栅格,每个子区域对应的预设物料投放量与处方图上对应的栅格的预设物料投放量相同或具有映射关系。
根据本公开的实施例,可以将作业覆盖区域中所有的子区域作为多个目标子区域,也可以将作业覆盖区域中部分子区域作为多个目标子区域。
根据本公开的实施例,目标子区域的数量也预先设定,例如,可以是5个,7个,10个等等。
根据本公开的实施例,每个目标子区域的预设物料投放量与目标子区域的面积相关,目标子区域的面积越大,预设物料投放量也可以越大。
在操作S204,根据多个目标子区域中每个目标子区域各自对应的预设物料投放量,确定与农业无人机当前的位置信息相匹配的实际物料投放量。
根据本公开的实施例,例如,可以将每个目标子区域各自对应的预设物料投放量进行加权求和,从而确定与农业无人机当前的位置信息相匹配的实际物料投放量。
根据本公开的实施例,在确定与农业无人机当前的位置信息相匹配的实际物料投放量之后,可以根据实际物料投放量控制农业无人机作业。例如,农业无人机可以控制喷洒系统按照一定的流量投放实际物料投放量的物料。
图3示意性示出了根据本公开实施例的农业无人机的作业覆盖区域的示意图。
如图3所示,农业无人机可以沿着如图3所示的航线飞行,图3中的网格以一定比例对应于农业无人机作业的处方图中的栅格。根据本公开的实施例,农业无人机当前处于位置301,以农业无人机当前的位置301为参考位置,根据农业无人机的喷幅宽度确定农业无人机的作业覆盖区域302。作业覆盖区域302中可以包括多个子区域。作业覆盖区域302例如可以是矩形区域,或者圆形区域等等。
根据本公开的实施例,从农业无人机的作业覆盖区域中确定多个目标子区域包括:以农业无人机当前的位置为中心,在农业无人机的作业覆盖区域中选择与中心间隔一个或多个预设距离的目标子区域。
根据本公开的实施例,如图3所示,以农业无人机当前的位置301为中心,与该中心间隔一个或多个预设距离的目标点303所在的区域为目标子区域,目标点303所在的区域可以是处方图中的栅格所在区域。
根据本公开的实施例,可以根据农业无人机的喷幅确定预设距离。例如,可以将三分之一的喷幅作为预设距离,或者,将四分之一的喷幅作为预设距离等等。
根据本公开的实施例,也可以不根据喷幅确定预设距离,例如,还可以按照经验设置预设距离,按照栅格的长度设置预设距离。通过本公开的实施例,基于农业无人机的喷幅或者栅格的长度确定预设距离,可以保证处方图上作业区域栅格内的用量的精确性,有效提升了变量作业的精度。
下面参考图4~图5,结合具体实施例对图2所示的方法做进一步说明。
图4示意性示出了根据本公开实施例的根据多个目标子区域中每个目 标子区域各自对应的预设物料投放量,确定与农业无人机当前的位置信息相匹配的实际物料投放量的流程图。
如图4所示,根据多个目标子区域中每个目标子区域各自对应的预设物料投放量,确定与农业无人机当前的位置信息相匹配的实际物料投放量包括操作S401~S402。
在操作S401,确定每个目标子区域的权重。
根据本公开的实施例,每个目标子区域的权重可以相同,也可以不同。确定每个目标子区域的权重的方式不做限定。
根据本公开的实施例,例如,可以先确定每个目标子区域和农业无人机当前的位置之间的距离,得到每个目标子区域各自对应的计算距离;以及根据每个目标子区域各自对应的计算距离,确定每个目标子区域的权重。
根据本公开的实施例,可以按照计算距离越小权重偏高,计算距离越大权重偏低的原则,确定每个目标子区域的权重。
在操作S402,根据每个目标子区域各自对应的预设物料投放量和权重,确定与农业无人机当前的位置信息相匹配的实际物料投放量。
根据本公开的实施例,例如,可以将每个目标子区域各自对应的预设物料投放量与每个目标子区域各自对应的权重进行加权求和,得到实际物料投放量。
通过本公开的实施例,基于处方图栅格划分较细,变量作业的用量不精准的问题,本公开的实施例提出一种精准用量的计算方法,实时获取飞机当前位置与作业范围区域内的用量,将每个目标子区域各自对应用量进行加权平均后,作为最优的用量替代单点的用量,该值更能代表当前位置下的实际需求用量,使变量作业更加精确。
根据本公开的实施例,根据每个目标子区域各自对应的计算距离,确定每个目标子区域的权重包括:将每个目标子区域各自对应的计算距离按照距离大小进行排序,得到排序结果;以及按照排序结果确定每个目标子区域的权重。
根据本公开的实施例,可以将每个目标子区域各自对应的计算距离按照从小到大进行排序,或者按照从大到小进行排序,得到排序结果;以及按照排序结果确定每个目标子区域的权重。
根据本公开的实施例,按照排序结果确定每个目标子区域的权重包括:在按照从小到大进行排序后得到的排序结果,为每个目标子区域配置权重的情况下,将排序在第i位的目标子区域的权重配置为大于排序在第i+1位的目标子区域的权重。
通过本公开的实施例,实现了计算距离越小权重偏高,计算距离越大权重偏低的原则,使得计算得到的实际物料投放量更能代表当前位置下的实需亩用量,使变量作业更加精确。
根据本公开的实施例,可以利用求均值的方法,根据多个目标子区域中每个目标子区域各自对应的预设物料投放量,确定与农业无人机当前的位置信息相匹配的实际物料投放量。
图5示意性示出了根据本公开另一实施例的根据多个目标子区域中每个目标子区域各自对应的预设物料投放量,确定与农业无人机当前的位置信息相匹配的实际物料投放量的流程图。
如图5所示,根据多个目标子区域中每个目标子区域各自对应的预设物料投放量,确定与农业无人机当前的位置信息相匹配的实际物料投放量包括操作S501~S503。
在操作S501,将每个目标子区域各自对应的预设物料投放量中,预设物料投放量最大和/或预设物料投放量最小的预设物料投放量进行滤除。
根据本公开的实施例,在目标子区域的数量较多时,例如,达到5个,10个目标子区域时,可以去除预设物料投放量最大和/或预设物料投放量最小的预设物料投放量,以使得计算得到的实际物料投放量更加精准。
在操作S502,计算剩余的目标子区域各自对应的预设物料投放量的平均值。
在操作S503,将剩余的目标子区域各自对应的预设物料投放量的平均值确定为实际物料投放量。
根据本公开的实施例,在计算实际物料投放量时,除了先去除预设物料投放量最大和/或预设物料投放量最小的预设物料投放量这一方案之外,也可以直接根据每个目标子区域各自对应的预设物料投放量,计算预设物料投放量的平均值;将平均值确定为实际物料投放量。
根据本公开的实施例,提供了多种计算与农业无人机当前的位置信息 相匹配的实际物料投放量的方法。
根据本公开的实施例,在确定农业无人机的实际物料投放量之后,可以获取农业无人机当前的作业参数,根据实际物料投放量和农业无人机当前的作业参数,确定农业无人机当前的作业流量。其中,作业参数包括以下一种或多种:作业飞行速度、作业时长、作业间距、农业无人机的喷幅宽度、农业无人机的飞行高度、喷头流速。
根据本公开的实施例,可以利用传感器等装置获取农业无人机当前的作业参数,例如包括但不限于位置传感器,如陀螺仪、定位天线、电子罗盘、惯性测量单元中的至少一种。又例如,还可以使用超声传感器、视觉传感器(单目传感器或者双目传感器)获取农业无人机的喷幅宽度,使用环境传感器和气压计等对其它作业信息进行获取。又或者,通过流量阀等装置获取喷头流速或流量等作业信息。
根据本公开的实施例,根据实际物料投放量和农业无人机当前的作业参数,确定农业无人机当前的作业流量可以参考上述一种或多种作业参数。例如,根据实际物料投放量和农业无人机当前的作业飞行速度,确定农业无人机当前的作业流量;或者,根据实际物料投放量、农业无人机当前的作业飞行速度和农业无人机的飞行高度,确定农业无人机当前的作业流量;或者,根据实际物料投放量、作业飞行速度和作业间距确定农业无人机当前的作业流量。
根据本公开的实施例,可以将实际物料投放量、作业飞行速度和作业间距相乘,得到乘积结果;根据乘积结果确定农业无人机当前的作业流量。
根据本公开的实施例,具体地,例如,参考图3所示,可以实时获取农业无人机的当前位置301,并获取与农业无人机的作业航线垂直的各间隔1/3喷幅处的目标点303对应的亩用量,即可同时获取农业无人机当前作业范围内的7个点对应的亩用量,之后对这7个点对应的亩用量进行加权平均。权重分配可以按照内侧权重偏高,外侧权重偏低的原则,得到当前作业区域内的最优亩用量,根据该最优亩用量计算得到农业无人机的作业流量,计算作业流量的公式可以参考如下公式(一)所示。
Figure PCTCN2020141049-appb-000001
其中,Mu为当前最优亩用量(单位可以是kg/亩,或L/亩),V为当 前飞行速度(单位可以是m/s),L为作业间距(即两条航线之间的距离,单位可以为m),flow为作业流量。
根据本公开的实施例,可以实现变量作业的精准亩用量计算,使用整个作业区域的最优亩用量值代替农业无人机当前位置的单点亩用量,保证了变量作业的精确性。
