具体地,所述无人机群的位置信息可以根据无人机群中至少一个无人机的位置信息来确定。例如,所述无人机群的位置信息可以根据无人机群中所有无人机的位置信息共同确定,或者可以根据无人机群中的某个或若干个无人机的位置信息来确定。进一步地,至少一个无人机的位置信息可以是对应的无人机的位置坐标,无人机群的位置信息可以是基于无人机群中的某个或若干个或全部无人机的位置坐标确定的无人机群的位置坐标。例如,在一种实施方式中,无人机群的位置信息可以是无人机群的中心位置的位置坐标,当然,在其他实施方式中,无人机群的位置信息也可以不限制在无人机群的中心位置的位置坐标,而是根据需要确定。下面对无人机群的位置坐标的确定进行具体举例说明。
在一实施例中,无人机群的位置坐标的确定方式具体为:从每个无人机的位置信息中获取每个无人机在高斯坐标系下的位置坐标;对每个无人机的位置坐标中的横坐标值进行求和,得到横坐标总值,并对每个所述无人机的位置坐标中的纵坐标值进行求和,得到纵坐标总值;统计无人机群中的无人机数量,并根据横坐标总值、纵坐标总值和无人机数量计算横坐标均值和纵坐标均值;将横坐标均值和纵坐标均值作为无人机群的位置坐标。通过将无人机的地理位置坐标投影到高斯坐标系,得到无人机在高斯坐标系的位置坐标,再基于无人机在高斯坐标系的位置坐标,确定无人机群的位置坐标,可以简化计算过程,提高计算速度,降低计算资源的占用。
可以理解的是,控制终端也可以基于每个无人机在高斯坐标系下的位置坐 标计算横坐标的方差值和纵坐标的方差值,将横坐标的方差值和纵坐标的方差值作为用于表示无人机群的第一位置信息;或者,还可以基于每个无人机在高斯坐标系下的位置坐标计算横坐标的均方根值和纵坐标的均方根值,将横坐标的均方根值和纵坐标的均方根值作为无人机群的位置坐标。本申请对此不作具体限定。
例如,无人机群包括3个无人机,且每个无人机在高斯坐标系的位置坐标分别为(A1,A2)、(B1,B2)和(C1,C2),则在高斯坐标系的无人机群的位置坐标为((A1+B1+C1)/3,((A2+B2+C2)/3))。
在一实施例中,控制终端根据无人机群中至少一个无人机的位置信息,确定无人机群的中心,并以该中心为圆心,预设距离为半径,形成圆形区域;获取位于该圆形区域内的无人机的位置信息,并根据位于该圆形区域内的无人机的位置信息,计算无人机群的位置坐标,且将该无人机群的位置坐标作为无人机群的位置信息。其中,无人机群的中心可以通过每个无人机的位置信息确定,即基于每个无人机的位置信息,确定无人机群的位置坐标,并将该无人机群的位置坐标作为无人机群的中心。无人机群的位置坐标的具体确定方式与另一实施例中的确定方式相同,此处再赘述。通过先确定无人机群的中心,再基于无人机群的中心周围的无人机的位置信息,确定无人机群的位置信息,可以提高无人机群的位置信息的准确性,便于后续执行多机作业航线规划。
在一实施例中,控制终端还可以根据无人机群中至少一个无人机的位置信息,确定该无人机群中各无人机构成的图形,并将该图形的重心或几何中心对应的位置坐标作为无人机群的位置信息。本申请对该图形的形状不作具体限定。通过每个无人机的位置信息,确定无人机群构成的图形,再将该图形的重心或几何中心对应的位置坐标作为无人机群的位置信息,可以提高无人机群的位置信息的准确性。
在一实施例中,控制终端还可以根据无人机群中至少一个无人机的位置信息,确定该无人机群中各无人机构成的图形,并获取位于该图形的边上的无人机的位置信息;根据位于该图形的边上的无人机的位置信息,确定无人机群的位置坐标,并将该无人机群的位置坐标作为无人机群的位置信息。通过每个无人机的位置信息,确定无人机群构成的图形,再基于位于该图形的边上的无人机的位置信息,确定无人机群的位置信息,可以提高无人机群的位置信息的准 确性。
可以理解,以上实施例仅为无人机群的位置信息的确定的示例性说明,也可以根据实际需要,灵活对无人机群的位置信息进行设置,例如先确定无人机群位于中心位置的无人机,并将此无人机的位置信息确定为该无人机群的位置信息,在此不作限定。
S1012、根据每个所述子作业区域中至少一个角点的位置信息,确定每个所述子作业区域的位置信息。
具体地,从每个子作业区域的位置信息中获取每个子作业区域的至少一个角点的位置坐标;根据每个子作业区域的至少一个角点的位置坐标,确定每个子作业区域的位置信息。其中,子作业区域的位置信息为用于表示子作业区域的中心位置的位置坐标。通过将角点的地理位置坐标投影到高斯坐标系,得到角点在高斯坐标系的位置坐标,再基于角点在高斯坐标系的位置坐标,确定子作业区域的位置信息,可以简化计算过程,提高计算速度,降低计算资源的占用。当然,子作业区域的位置信息不限于子作业区域的中心位置的位置坐标,也可以根据实际需要,灵活对无人机群的位置信息进行设置,在此仅为示例性说明,不作限定。
进一步地,角点的位置坐标为高斯坐标系下的位置坐标,控制终端从每个子作业区域的至少一个角点的位置坐标中获取每个子作业区域的至少一个角点的横坐标值和纵坐标值;分别对每个子作业区域的至少一个角点的横坐标值进行求和,得到每个子作业区域的横坐标总值;分别对每个子作业区域的至少一个角点的纵坐标值进行求和,得到每个子作业区域的纵坐标总值;确定每个子作业区域对应的角点数量;根据每个子作业区域各自对应的横坐标总值、纵坐标总值和角点数量计算每个子作业区域各自对应的横坐标均值和纵坐标均值;将计算得到的每个子作业区域各自对应的横坐标均值和纵坐标均值作为每个子作业区域的位置信息。
需要说明的是,也可以先确定每个子作业区域对应的角点数量和角点的位置坐标,再基于每个角点在高斯坐标系下的位置坐标和子作业区域对应的角点数量,计算子作业区域对应的横坐标均值和纵坐标均值,本申请对此不作具体限定。

以单个子作业区域为例,子作业区域包括3个角点,且每个角点在高斯坐标系的位置坐标分别为(X1,Y1)、(X2,Y2)和(X3,Y3),则子作业区域在高斯坐标系的位置坐标为((X1+X2+X3)/4,(Y1+Y2+Y3)/3)。
在一实施例中,每个子作业区域的角点数量基于子作业区域的形状确定,例如,子作业区域为三角形,则子作业区域的角点数量为三个,且角点分别为三角形子作业区域的三个顶点,又例如,子作业区域为四边形,则子作业区域的角点数量为四个,且角点分别为四边形子作业区域的四个顶点。可以理解的是,每个子作业区域的角点数量还可以基于实际情况进行设置,本申请对此不作具体限定。
进一步地,可以理解,步骤S1011和步骤S1012无先后顺序,可以先执行步骤S1011,再执行步骤S1012,也可以先执行步骤S1012,再执行步骤S1011,或者可以二者同时执行。即,可以确定所述无人机群的位置信息,再确定每个所述子作业区域的位置信息;也可以确定每个所述子作业区域的位置信息,再确定所述无人机群的位置信息;或者还可以同时确定所述无人机群的位置信息和每个所述子作业区域的位置信息,在此不作限定。
在一实施例中,当控制终端接收到用户触发的多机作业航线规划指令时,控制终端显示多机作业航线规划界面,该多机作业航线规划界面显示待作业的作业区域列表和可执行作业的无人机列表;获取用户在该作业区域列表中选择的每个子作业区域以及在该无人机列表中选择的无人机,并汇集选择的每个每个子作业区域,以形成待作业的作业区域以及汇集选择的每个无人机,以形成待分配子作业区域的无人机群。通过多机作业航线规划界面,可以方便用户选择待作业的作业区域和可执行作业的无人机,极大的提高了用户体验。
在需要进行多机作业航线规划时,控制终端获取无人机群的位置信息和作业区域中每个子作业区域的位置信息。其中,控制终端分别与无人机群中的每个无人机进行连接,在连接之后,控制终端可以通过全球定位系统(GPS)或实时动态差分法(RTK)等方式获取无人机群的经纬度坐标,并将该经纬度坐标作为无人机群的位置信息,或者将无人机群的经纬度坐标投影到高斯坐标系, 得到无人机群的经纬度坐标在高斯坐标系下的投影,记为高斯坐标,并将该高斯坐标作为无人机群的位置信息。通过全球定位系统(GPS)或实时动态差分法(RTK)等方式可以实时的获取无人机群的位置信息,有效的提高无人机群的位置信息的准确性。
在一实施例中,在需要进行多机作业航线规划时,可以将外部存储设备或服务器中的对应作业区域中每个子作业区域的位置信息导入本地进行存储,在另一种实施方式中,也可以直接从外部存储设备或服务器中直接读取对应作业区域中每个子作业区域的位置信息,而不进行本地存储,在此不作具体限定。
S102、根据所述无人机群的位置信息和每个所述子作业区域的位置信息,计算每个所述子作业区域与所述无人机群之间的距离。
控制终端根据无人机群的位置信息和每个子作业区域的位置信息,计算每个子作业区域与无人机群之间的距离。其中,控制终端可以基于半正矢(haversine)公式根据无人机群的地理位置坐标和每个子作业区域的地理位置坐标,计算无人机群与每个子作业区域之间的距离。通过无人机群的位置信息和每个子作业的位置信息,可以准确且快速的计算得到每个子作业区域与无人机群之间的距离。

S103、根据所述无人机群的位置信息、每个所述子作业区域的位置信息和每个所述子作业区域与所述无人机群之间的距离,执行对应的多机作业航线规划操作。
控制终端根据无人机群的位置信息、每个子作业区域的位置信息和每个子作业区域与无人机群之间的距离,执行多机作业航线规划操作,即按照每个子作业区域与无人机群之间的距离,结合无人机群的位置信息与每个子作业区域的位置信息,将子作业区域分配给无人机群中的无人机,并规划无人机与子作业区域之间的航线。通过综合考虑无人机群的位置信息、子作业区域的位置信息以及子作业区域与无人机群之间的距离,可以较优的给无人机分配子作业区域和规划合适的航线,减少无人机在作业或返航过程中出现交叉干扰的情况发生,有效的提高多机分区作业的效率。

S1031、根据每个所述子作业区域与所述无人机群之间的距离的大小,对所述作业区域中的每个子作业区域进行排序,得到子作业区域分配队列。
具体地,控制终端按照每个子作业区域与无人机群之间的距离的大小,对子作业区域群中的每个子作业区域进行排序,得到子作业区域分配队列,需要说明的是,距离越小,则排序越靠前,距离越大,则排序越靠后。例如,作业区域包括6个子作业区域,分别为子作业区域A、子作业区域B、子作业区域C、子作业区域D、子作业区域E和子作业区域F,且这6个子作业区域与无人机群之间的距离分别为1000米、800米、850米、500米、900米和950米,由于500米<800米<850米<900米<950米<1000米,则排序得到的子作业区域分配队列的排序为子作业区域D-子作业区域B-子作业区域C-子作业区域E-子作业区域F-子作业区域A。
S1032、按照所述子作业区域分配队列中的所述子作业区域的排序,依次从所述作业区域中获取一个所述子作业区域作为目标子作业区域。
具体地,在得到子作业区域分配队列之后,控制终端按照该子作业区域分配队列中的子作业区域排序,依次从该子作业区域群中获取一个子作业区域作为目标子作业区域。例如,排序得到的子作业区域分配队列的排序为子作业区域D-子作业区域B-子作业区域C-子作业区域E-子作业区域F-子作业区域A,则按照子作业区域D-子作业区域B-子作业区域C-子作业区域E-子作业区域F-子作业区域A的顺序,依次从该子作业区域群中获取一个子作业区域作为目标 子作业区域,即首先将子作业区域D作为目标子作业区域,之后将子作业区域B作为目标子作业区域,再之后将子作业区域C作为目标子作业区域,以此类推,最后将子作业区域A作为目标子作业区域。
S1033、根据每个所述无人机的当前属性信息、所述目标子作业区域的位置信息和每个所述无人机的位置信息,确定目标无人机。

在一实施例中,如图4所示,子步骤S1033具体包括:子步骤S10331至S10334。
S10331、根据每个无人机的当前属性信息,确定候选无人机,其中,候选无人机为待分配子作业区域的无人机。
具体地,根据每个无人机的当前属性信息中的状态标识符,确定每个无人机的当前状态;将当前状态为空闲状态的无人机作为候选无人机。其中,无人机的当前状态的确定方式具体为:根据每个无人机的当前属性信息中的状态标识符,确定基准标识符,该基准标识符随着每个无人机的当前属性信息中的状态标识符的改变而发生改变;将当前属性信息中的状态标识符为基准标识符的无人机的当前状态确定为空闲状态;将当前属性信息中的状态标识符不为基准标识符的无人机的当前状态确定为占用状态。
在一实施例中,基准标识符的确定方式具体为:确定每个无人机的当前属性信息中的状态标识符是否相同;如果每个无人机的当前属性信息中的状态标识符均相同,则将相同的状态标识符作为基准标识符;如果存在至少一个无人机的当前属性信息中的状态标识符不同,则将最小的状态标识符作为基准标识符。需要说明的是,在无人机群中的无人机的数量大于或等于子作业区域的数量的时候,该基准标识符保持不变,而在无人机群中的无人机的数量小于子作业区域的数量的时候,该基准标识符随着每个无人机的当前属性信息中的状态标识符的改变而发生改变。
例如,无人机群包括3个无人机,分别为无人机A、无人机B和无人机C, 初始状态下无人机A、无人机B和无人机C的状态标识符均为0,也即基准标识符也为0,而子作业区域也为3个,初始状态下,三个无人机均为候选无人机,在第一次分配时,给无人机A分配了一个子作业区域,此时,无人机A、无人机B和无人机C的状态标识符为1、0和0,则候选无人机包括无人机B和无人机C,而在第二次分配时,给无人机C分配了一个子作业区域,此时,无人机A、无人机B和无人机C的状态标识符为1、0和1,则候选无人机为无人机B,则将最后一个子作业区域分配给无人机B,此时,无人机A、无人机B和无人机C的状态标识符均为1,而如果子作业区域为5个,经过三次分配之后,无人机A、无人机B和无人机C的状态标识符均为1,则可确定基准标识符由0变为1,此时无人机A、无人机B和无人机C为的当前状态为空闲状态,可以继续给无人机A、无人机B和无人机C分配子作业区域。
需要说明的是,无人机的状态标识符随着子作业区域的分配而发生改变,具体的改变方式可基于实际情况进行设置,本申请对此不作具体限定,可选地,无人机的状态标识符为0时,表示该无人机未分配子作业区域,无人机的状态标识符为1时,表示该无人机分配一个子作业区域,无人机的状态标识符为2时,表示该无人机分配两个子作业区域,以此类推,无人机的状态标识符为N时,表示该无人机分配N个子作业区域。
S10332、根据目标子作业区域的位置信息和每个候选无人机的位置信息,计算目标子作业区域与每个候选无人机之间的距离。
具体地,控制终端从目标子作业区域的位置信息中获取目标子作业区域的每个角点在高斯坐标系下的位置坐标;根据目标子作业区域的每个角点的位置坐标和每个候选无人机的位置信息,计算目标子作业区域的每个角点与每个候选无人机之间的距离;根据目标子作业区域的每个角点与每个候选无人机之间的距离,计算目标子作业区域与每个候选无人机之间的距离。通过计算每个角点与候选无人机之间的距离,再基于每个角点与候选无人机之间的距离,可以准确的计算目标子作业区域与候选无人机之间的距离,可以提高多机作业航线规划的准确性,进一步地减少无人机在作业或返航过程中出现交叉干扰的情况发生。
在一实施例中,角点与候选无人机之间的距离的计算方式具体为:控制终端从每个候选无人机的位置信息中获取每个候选无人机在高斯坐标系下的位置坐标;从目标子作业区域的每个角点的位置坐标中获取目标子作业区域的每个角点的横坐标值和纵坐标值;从每个候选无人机的位置坐标中获取每个候选无 人机的横坐标值和纵坐标值;根据目标子作业区域的每个角点的横坐标值和纵坐标值,以及每个候选无人机的横坐标值和纵坐标值,计算目标子作业区域的每个角点与各候选无人机之间的距离。
在一实施例中,目标子作业区域与候选无人机之间的距离的计算方式具体为:控制终端分别对所述目标子作业区域的每个角点与每个所述候选无人机之间的距离进行求和,得到所述目标子作业区域与每个所述候选无人机之间的角点总距离;获取目标子作业区域的角点个数,并根据角点个数,计算每个角点总距离的平均值;将每个角点总距离的平均值作为目标子作业区域与每个候选无人机之间的距离。
以单个候选无人机为例,解释说明目标子作业区域与候选无人机之间的距离的计算过程,设目标子作业区域包括3个角点,分别为角点A、角点B和角点C,且在高斯坐标系下的位置坐标分别为(X1,Y1)、(X2,Y2)和(X3,Y3),且候选无人机在高斯坐标系下的位置坐标为(X4,Y4),则角点A、角点B和角点C与候选无人机之间的距离分别为

则目标子作业区域与候选无人机之间的距离为(d A+d B+d C)/3。
S10333、根据目标子作业区域与每个候选无人机之间的距离,从每个候选无人机中确定目标无人机。
获取目标子作业区域与每个候选无人机之间的距离最短的候选无人机,并将目标子作业区域与每个候选无人机之间的距离最短的候选无人机作为目标无人机。通过确定候选无人机,并将目标子作业区域与每个候选无人机之间的距离最短的候选无人机作为目标无人机,可以保证分配给无人机的子作业区域之间的距离最短,可以有效的提高多机分区作业的效率。
例如,候选无人机分别为无人机A、无人机B和无人机C,目标子作业区域为子作业区域A,且子作业区域A与无人机A、无人机B和无人机C之间的距离分别为800米、600米和750米,由于600米<750米<800米,则子作业区域A与无人机B之间的距离最短,因此将无人机B作为目标无人机。
在一实施例中,目标无人机的确定方式具体为:获取目标子作业区域的作业任务信息,其中,作业任务信息用于描述目标子作业区域的作业任务;根据作业任务信息、每个候选无人机的当前属性信息和目标子作业区域与每个候选无人机之间的距离,确定目标无人机。其中,作业任务信息包括目标子作业区 域的作业任务类型、作业面积和作业航线等,候选无人机的当前属性信息包括候选无人机的类型标签和当前剩余电量,类型标签用于表示无人机的类型。
其中,基于当前属性信息、作业任务信息和目标子作业区域与每个候选无人机之间的距离,确定目标无人机的方式具体为:从该作业任务信息中获取作业任务类型,并根据每个候选无人机的当前属性信息中的类型标签,确定是否存在至少一个候选无人机的类型标签与该作业任务类型匹配,如果存在至少一个候选无人机的类型标签与该作业任务类型匹配,则将匹配到的,且与目标子作业区域之间的距离最短的候选无人机作为目标无人机;如果不存在候选无人机的类型标签与该作业任务类型匹配,则获取目标子作业区域与每个候选无人机之间的距离最短的候选无人机,并将获取到的候选无人机作为目标无人机。
或者,从该作业任务信息中获取作业面积,并根据每个候选无人机的当前属性信息中的当前剩余电量,确定是否存在至少一个候选无人机的当前剩余电量与该作业面积匹配,如果存在至少一个候选无人机的当前剩余电量与该作业面积匹配,则将匹配到的,且与目标子作业区域之间的距离最短的候选无人机作为目标无人机;如果不存在候选无人机的当前剩余电量与该作业面积匹配,则获取目标子作业区域与每个候选无人机之间的距离最短的候选无人机,并将获取到的候选无人机作为目标无人机。其中,如果当前剩余电量满足执行该作业面积所需的电量,则确定当前剩余电量与该作业面积匹配,反之,如果当前剩余电量不满足执行该作业面积所需的电量,则确定当前剩余电量与该作业面积不匹配。
S1034、将所述目标子作业区域分配给所述目标无人机,并规划所述目标无人机与所述目标子作业区域之间的航线。
在确定目标子作业区域和目标无人机之后,控制终端将目标子作业区域分配给目标无人机,并规划目标无人机与目标子作业区域之间的航线。进一步地,在将目标子作业区域分配给目标无人机之后,控制终端调整目标无人机的当前属性信息,即调整目标无人机的状态标识符。
其中,无人机与子作业区域之间的航线的规划方式具体为:在子作业区域分配完成之后,基于每个无人机的位置信息和每个子作业区域的位置信息,在预设的作业地图中标记每个无人机的位置点和每个子作业区域的位置点;按照子作业区域与无人机的分配关系在该作业地图中将无人机的位置点与子作业区 域的位置点进行直线连线;确定连线的各直线之间是否存在交点,如果各直线之间存在交点,则调整对应的无人机在交点位置处的高度,使得无人机在到达交点位置时,不会相撞,从而完成无人机与子作业区域之间的航线的规划。在其他实施例中,当连线的直线之间存在交点时,也可以绕过交点处,使得无人机的位置点与子作业区域的位置点进行折线连接,或者曲线连接,以使得无人机在到达交点位置时,不会相撞。
在一实施例中,在完成多机作业航线规划之后,控制终端获取多机作业航线规划结果,并根据多机作业航线规划结果生成多机作业任务;从多机作业任务中获取执行作业的每个无人机的作业任务,并将执行作业的每个无人机的作业任务发送至对应的无人机。其中,该多机作业航线规划结果包括分配完成后的无人机与子作业区域,无人机与子作业区域之间的航线和子作业区域的作业航线,通过无人机与子作业区域、无人机与子作业区域之间的航线和子作业区域的作业航线即可生成包含每个无人机的作业任务的多机作业任务。
可以理解的是,子作业区域的作业航线可以提前规划完成,也可以在生成多机作业任务时,基于子作业区域的信息和分配的无人机实时规划,且作业航线包括环绕航线和带状航线等,本申请不作具体限定。

其中,子作业区域的中心位置的位置坐标的确定方式具体为:从子作业区域的位置信息中获取至少一个角点在高斯坐标系下的位置坐标,并根据至少一个角点在高斯坐标系下的位置坐标,确定子作业区域的中心位置的位置坐标。例如,子作业区域包括3个角点,且每个角点在高斯坐标系的位置坐标分别为(X1,Y1)、(X2,Y2)和(X3,Y3),则子作业区域的中心位置在高斯坐 标系的位置坐标为((X1+X2+X3)/4,(Y1+Y2+Y3)/3)。
在一实施例中,每个无人机与每个子作业区域之间的距离的计算方式还可以为:以一个子作业区域与一个无人机为例,计算子作业区域的至少一个角点与无人机之间的距离,并分别对该子作业区域的每个角点与无人机之间的距离进行求和,得到该子作业区域与每个无人机之间的角点总距离,然后统计该子作业区域的角点数量,并根据该角点数量和角点总距离,计算平均角点距离,且将该平均角点距离作为该子作业区域与无人机之间的距离,按照同样的方式即可计算得到每个无人机与每个子作业区域之间的距离。
例如,子作业区域包括3个角点,分别为角点a、角点b和角点c,且在高斯坐标系下的位置坐标分别为(x1,x1)、(x2,x2)和(x3,x3),且无人机在高斯坐标系下的位置坐标为(x4,x4),则角点a、角点b和角点c与无人机之间的距离分别为

则子作业区域与无人机之间的距离为(d a+d b+d c)/3。

其中,无人机的当前属性信息包括无人机的当前状态对应的状态标识符、类型标签和当前剩余电量,状态标识符用于标识无人机的状态,包括空闲状态和占用状态,类型标签用于表示无人机的类型。该分配标识信息用于表示子作业区域的分配情况,当分配标识信息为预设的第一信息时,表示子作业区域未被分配,当分配标识信息为预设的第二信息时,表示子作业区域已被分配。需要说明的是,上述第一信息和第二信息可基于实际情况进行设置,本申请对此不作具体限定。可选地,第一信息为0,第二信息为1。
在一实施例中,无人机的状态标识符为0时,表示该无人机未分配子作业区域,无人机的状态标识符为1时,表示该无人机分配一个子作业区域,无人机的状态标识符为2时,表示该无人机分配两个子作业区域,以此类推,无人机的状态标识符为N时,表示该无人机分配N个子作业区域。
S207、根据每个所述无人机的当前属性信息、每个所述子作业区域的分配标识信息以及每个所述无人机与每个所述子作业区域之间的距离,执行对应的多机作业航线规划操作。

例如,候选子作业区域分别为子作业区域1、子作业区域2和子作业区域3,候选无人机分别为无人机A、无人机B和无人机C,且子作业区域1与无人机A、无人机B和无人机C之间的距离分别为800米、600米和900米,子作业区域2与无人机A、无人机B和无人机C之间的距离分别为500米、700米和850米,子作业区域3与无人机A、无人机B和无人机C之间的距离分别为600米、650米和750米,则500米<600米<650米<700米<750米<800米<850米<900米,则最短距离为500,因此将子作业区域2和无人机A确定为目标子作业区域和目标无人机。
在一实施例中,候选子作业区域的确定方式具体为:确定每个子作业区域的分配标识信息是否均为预设信息;若每个子作业区域的分配标识信息均为预设信息,则确定每个子作业区域中不存在候选子作业区域;若存在至少一个子作业区域的分配标识信息不为预设值,则将分配标识信息不为预设值的子作业区域作为候选子作业区域。可选地,该预设信息为1,子作业区域的分配标识信息为0,则表示该子作业区域未被分配,子作业区域的分配标识信息为1,则表示该子作业区域被分配。
在一实施例中,候选无人机的确定方式具体为:根据每个无人机的当前属性信息中的状态标识符,确定基准标识符,该基准标识符随着每个无人机的当前属性信息中的状态标识符的改变而发生改变;将当前属性信息中的状态标识符为基准标识符的无人机确定为候选无人机。其中,基准标识符的确定方式具体为:确定每个无人机的当前属性信息中的状态标识符是否相同;如果每个无人机的当前属性信息中的状态标识符均相同,则将相同的状态标识符作为基准标识符;如果存在至少一个无人机的当前属性信息中的状态标识符不同,则将最小的状态标识符作为基准标识符。需要说明的是,在无人机的数量大于或等 于子作业区域的数量的时候,该基准标识符保持不变,而在无人机的数量小于子作业区域的数量的时候,该基准标识符随着每个无人机的当前属性信息中的状态标识符的改变而发生改变。
上述实施例提供的多机作业航线规划方法,在待作业的子作业区域较少时,按照距离最短策略根据每个无人机的状态标识符、每个子作业区域的分配标识信息以及每个无人机与每个子作业区域之间的距离,执行对应的多机作业航线规划操作,在待作业的子作业区域较多时,根据无人机群的位置信息、每个子作业区域的位置信息和每个子作业区域与无人机群之间的距离,执行对应的多机作业航线规划操作,可以基于子作业区域的数量自适应选择对应的多机作业规划策略,可以较优的给无人机分配子作业区域,减少无人机在作业或返航过程中出现交叉干扰的情况发生,有效的提高多机分区作业的效率。
