目前,目前无人机可以实现航线飞行和对目标对象的环绕飞行。其中,在航线过程中,通过将一系列用户设置好的航点上传至无人机中,无人机通过遍历航线中的每一个航点来实现根据用户设定的路线飞行。在对目标对象的环绕飞行中,无人机绕着选定的目标对象,以一定的方向、半径和速度飞行。在某些实际应用中,无人机既需要执行对目标对象环绕飞行,又需要执行航线飞行。例如,在测绘领域,如需要连续对几栋建筑物进行测绘时,既包含对建筑物的环绕飞行,又需要从一栋建筑物到另一栋建筑物的航线飞行。然而,现有的无人机控制策略中,航线飞行和目标对象环绕两个功能都是单独应用的。也就是说,目前的航线飞行和对目标对象的环绕飞行不能结合,这样可能不能满足用户的实际应用需求。

下面结合附图,对本发明的一些实施方式作详细说明。在不冲突的情况下,下述的实施例及实施例中的特征可以相互组合。
在应用飞行器的过程中,尤其是针对无人飞行器(也可以称为无人机)的应用过程中,通过控制终端对对应的无人机进行控制,使其在确定的区域范围对确定的目标对象,即目标对象或作业目标,进行环绕飞行,以及控制各个目标对象之间根据确定的拼接航段信息进行飞行。具体过程通过以下实施例进行详细说明。
如图1所示,为本发明实施例提供的控制终端的控制方法的流程图。本实施例中的方法,可以包括:
步骤S101、确定多个目标对象中每一个的目标对象指示信息;
具体地,控制终端可以包括与用户进行交互的交互装置,其中用户可以通过对交互装置进行操作来选定多个目标对象,控制终端的处理器可以对交互装置接收到的用户的操作进行分析,以确定用户选中的多个目标对象的目标对象指示信息。
在某些实施例中,所述目标对象指示信息可以是目标对象的位置信息,其中,位置信息可以为目标对象的绝对位置信息,例如经度、纬度、高度等,位置信息也可以为相对位置信息,例如相对于某个参考物的位置信息。在具体实现中,用户可以通过控制终端的交互装置输入目标对象的绝对位置信息,或者输入相对于参考物的位置信息,控制终端将所述位置坐标发送给无人机,另外,用户可以在交互装置上显示的地图上通过打点操作确定目标对象,控制终端将通过打点操作确定的目标对象的位置坐标发送给无人机。无人机在接收到所述位置坐标后,即可以确定目标对象。
在某些实施例中,所述指示信息也可以是目标对象在控制终端的交互装置上显示的图像中的位置。具体地,控制终端的交互装置可以显示无人机上的拍摄设备拍摄的图像,用户可以在所述图像上通过点击或者框选的方式选中目标对象,控制终端可以将目标对象在图像中的位置信息发送给无人机,无人机可以根据所述位置信息确定目标对象。
其中,交互装置可以包括触摸显示屏、按键、键盘、摇杆、波轮中的一种或多种。如图2所示,用户在交互装置上显示的地图上预先确定的目标对象A、B、C、D,控制终端确定这四个目标对象的指示信息。其中,H点为无人机当前位置。
步骤S102、确定所述多个目标对象中各个目标对象之间的拼接航段信息。
具体地,各个目标对象具有确定的环绕飞行信息。控制终端在控制各个目标对象根据各自对应的环绕飞行信息进行环绕飞行,会形成各自对应的环绕区域。无人机在对多个目标对象进行环绕飞行的过程中,需要从一个目标对象的环绕区域飞行到下一个目标对象的环绕区域,用户可以对无人机从一个环绕区域飞行到下一个环绕区域之间的过程进行设置,即用户可以对多个目标对象之间的拼接航段信息进行设置。其中,航线拼接信息可以是对无人机从一个环绕区域飞行到下一个环绕区域的过程进行描述的任何信息。进一步地,用户可以控制终端的交互装置进行操作,对所述多个对象之间的每两个目标对象之间的拼接航段信息进行设置,交互装置接收并检测用户的操作,控制终端的处理器确定与用户的操作对应的拼接航段信息。
步骤S103、控制无人机对所述目标对象指示信息所指示的多个目标对象中的每一个目标对象进行环绕飞行。
在本实施例中,控制终端在确定了所述多个目标对象的目标对象指示信息后,可以将所述目标对象指示信息发送给无人机,无人机在接收到所述目标对象指示信息后,通过所述目标对象确定所述多个目标对象,即控制终端通过所述目标对象指示信息控制无人机对多个目标对象的每一个目标对象进行环绕飞行。
步骤S104、在完成对一个目标对象的环绕飞行后向下一个目标对象飞行的过程中,根据对应的拼接航段信息控制无人机向所述下一个目标对象飞行。
在具体实现过程中,控制终端控制无人机从起飞位置开始向第一个目标对象飞行,然后在到达第一个目标对象后,然后根据该第一个目标对象确定的环绕飞行方式进行飞行,并在完成后,根据确定的拼接航段信息向下一个目标对象飞行,依此执行,完成针对确定的多个目标对象的环绕飞行以及多个目标对象之间的航线飞行。
控制终端可以为遥控器、智能手机、平板电脑、地面控制站、膝上型电脑、穿戴式设备(手表、手环)等及其组合。
需要说明的是,本实施例中,图1公开的步骤S101和步骤S102可以没有先后顺序。
本实施例中控制终端在控制无人机飞行的过程中,通过确定多个目标对象的目标对象指示信息,以及各个目标对象之间的拼接航段信息;然后,通过控制无人机对所述目标对象指示信息所指示的多个目标对象中的每一个环绕飞行,在完成对一个目标对象的环绕飞行后向下一个目标对象飞行的过程中,根据对应的拼接航段信息控制无 人机向该下一个目标对象飞行。通过上述方式,能够控制无人机在飞行的过程中,即实现了目标对象环绕飞行又能实现航线飞行,使得无人机在飞行中更加灵活有效,从而能够满足各种行业或领域的对无人机的灵活性和应用需求。
本发明实施例提供了一种控制终端的控制方法。在图1示出的实施例的基础上,图3为本发明实施例提供了另一种控制终端的控制方法的流程图。所述控制方法包括:
步骤S301、确定多个目标对象中每一个的目标对象指示信息;
步骤S301和步骤S101的具体方法和原理一致,此处不再赘述。
步骤S302、确定多个目标对象中每一个目标对象的环绕飞行信息。
具体地,为了对每一个目标对象的环绕飞行过程进行精细化和多样化的控制,用户可以对交互装置进行操作,在交互装置上对环绕飞行信息进行设置,交互装置对用户的操作进行接收并检测,控制终端的处理器通过对交互装置接收到的操作进行分析,确定与所述操作相对应的环绕飞行信息。其中,所述环绕信息可以是对环绕飞行过程进行描述的任何参数。在实际应用中,控制终端所确定的各个目标对象的环绕飞行信息至少包括:环绕半径、环绕初始半径、环绕半径的变化率、环绕结束半径、环绕速度、环绕角度、环绕方向、环绕速度变化率、环绕飞行起始位置点、环绕圈数、环绕角度、环绕开始位置、环绕飞行时间、环绕飞行时无人机的机头朝向、垂直方向的环绕速度中的一种或多种。
其中,环绕方向指顺时针旋转或逆时针旋转。环绕飞行时无人机的机头朝向至少包括机头朝向目标对象方向、机头背离目标对象方向、机头朝向环绕速度方向、机头背离环绕速度方向等等。环绕的开始位置可以是相对于目标对象的正西、正北、或距离目标对象最近或最远的位置、也可以是用户通过控制终端指定的其他位置,此处不作具体限制。用户可以通过控制终端设置环绕飞行的环绕半径,即无人机根据这个固定不变的环绕半径对目标对象进行环绕飞行。在某些情况,在对目标对象进行环绕飞行时,无人机的环绕半径是可变的,用户可以通过控制终端设置环绕初始半径和环绕半径的变化率,则无人机在环绕飞行的过程中从环绕开始时的环绕半径根据环绕半径的变化率来逐渐增大或者缩小。在某些情况下用户可以通过控制终端设置环绕初始半径、环绕结束半径和环绕飞行时间,即在预设的环绕飞行时间内,在环绕飞行的过程中,环绕半径从环绕初始半径逐渐变为环绕结束半径。用户还可以设置在垂直方向的环绕速度,这样无人机在环绕飞行的过程中,可以实现从上到下或者从下到上对目标 对象进行环绕。实现在水平方向和垂直方向上两个维度的运动。
步骤S303、确定所述多个目标对象中各个目标对象之间的拼接航段信息。
具体地,拼接航段信息包括拼接航段的轨迹信息,其中,所述轨迹信息可以指示无人机从一个环绕区域飞行到下一个环绕区域的过程中的飞行轨迹。另外,拼接航段信息也可以包括拼接航段的轨迹属性信息,其中所述轨迹属性信息可以指示无人机从一个环绕区域飞向下一个环绕区域过程中除轨迹信息以外的任何其他信息,在实际应用中,该拼接航段的轨迹属性信息包括速度、加速度、机头朝向、云台姿态、摄像头的控制方式中的一种或多种。为了对无人机在多个目标对象之间的飞行过程进行进一步的控制,用户可以对交互装置进行操作,对轨迹信息和/或轨迹属性信息进行设置,控制终端的处理器确定与检测交互装置接收到的操作相对应的轨迹信息和/或轨迹属性信息。
步骤S304、根据所述环绕飞行信息控制无人机对所述多个目标对象中的每一个目标对象进行环绕飞行。
具体地,控制终端可以将所述环绕信息发送给无人机,无人机在接收到所述环绕信息后可以根据所述环绕信息对每一个目标对象进行环绕飞行,即控制终端通过所述环绕信息控制无人机对所述多个目标对象中的每一个目标对象进行环绕飞行。
在具体实现过程中,如图4所示,为4个目标对象的环绕确定飞行信息后,控制终端控制无人机对该目标对象进行环绕飞行时的示意图。结合图2和下述表1对图4中各个目标对象的环绕飞行信息进行详细说明。
表1:目标对象确定的环绕飞行信息
Figure PCTCN2017091128-appb-000001
Figure PCTCN2017091128-appb-000002
基于上表1中目标对象A、B、C、D确定的环绕飞行信息。如图4所示,无人机对目标对象A环绕飞行的环绕飞行起始位置点为PA,环绕圈数为1.7圈,因没有环绕半径的变化率和垂直方向上的速度,因此会形成一个逆时针旋转的标准的圆形环绕轨迹。
同样的,基于表1中的环绕飞行信息,目标对象B由于具有半径变化,因此形成了如图4所示的,环绕飞行起始位置点为PB的渐开线的环绕轨迹。
同样的,基于表1中的环绕飞行信息,目标对象C则由于具有垂直方向环绕速度即高度方向上的速度,因此会形成如图4所示的,环绕飞行起始位置点为PC的一个螺旋线的环绕轨迹。
同样的,基于表1中的环绕飞行信息,目标对象D由于同时具有环绕半径的变化率和垂直方向环绕速度,因此会形成如图4所示的,环绕飞行起始位置点为PD的一个渐开螺旋的环绕轨迹。
步骤S305、在完成对一个目标对象的环绕飞行后向下一个目标对象飞行的过程中,根据对应的拼接航段的轨迹信息指示的轨迹控制无人机向所述下一个目标对象飞行。
如前所述,拼接航段信息可以包括拼接航段的轨迹信息。根据对应的拼接航段的轨迹信息指示的轨迹控制无人机向所述下一个目标对象飞行可以包括:根据拼接航段的轨迹信息指示的轨迹控制无人机向所述下一个目标对象飞行。在实际应用中,所述根据拼接航段的轨迹信息指示的轨迹控制无人机向所述下一个目标对象飞行可以通过如下几种可行方式实现:
第一种可行方式:所述轨迹信息包括内切轨迹信息,在完成对与所述内切轨迹信息对应的一个目标对象的环绕飞行后向下一个目标对象飞行的过程中,根据所述内切轨迹信息指示的内切轨迹向所述下一个目标对象飞行。如图5A所示,当一个目标对象的环绕区域与下一个目标对象的环绕区域在同一个水平面上时,用户可以通过控制终端的交互装置进行操作,确定内切轨迹信息,控制终端将所述内切轨迹信息发送给 无人机,无人机根据内切轨迹信息指示的内切轨迹从一个目标对象飞行至下一个目标对象。
在某些实施例中,如图5A所示,内切轨迹一共有2种,在用户可以通过交互装置进行选取确定内切轨迹后,自动生成起始点5A1和5A2,终止点5A3和5A4。在某些情况中,用户在交互装置上确定了内切轨迹信息后,控制终端可以自动从2种内切轨迹中为两个环绕区域匹配一种内切轨迹。
第二种可行方式:所述轨迹信息包括外切轨迹信息,在完成对与所述外切轨迹信息对应的一个目标对象的环绕飞行后向下一个目标对象飞行的过程中,根据所述外切轨迹信息指示的外切轨迹向所述下一个目标对象飞行。
如图5B所示,当一个目标对象的环绕区域与下一个目标对象的环绕区域在同一个水平面上时,用户可以通过控制终端的交互装置进行操作,确定外切轨迹信息,控制终端将所述外切轨迹信息发送给无人机,无人机根据外切轨迹信息指示的外切轨迹从一个目标对象飞行至下一个目标对象。
在某些实施例中,如图5B所示,外切轨迹一共有2种,用户可以通过交互装置进行选取确定外切轨迹后,自动生成起始点5B1和5B2,终止点5B3和5B4。在某些情况中,用户在交互装置上确定了外切轨迹信息后,控制终端可以自动从2种外切轨迹中为两个环绕区域匹配一种外切轨迹。
第三种可行方式:所述轨迹信息包括环绕飞行起始位置点和环绕飞行结束位置点外切,在完成对与所述外切轨迹信息对应的一个目标对象的环绕飞行后向下一个目标对象飞行的过程中,控制无人机从所述一个目标对象的环绕飞行结束位置点向所述下一个目标对象的环绕飞行起始位置点飞行。如图5C所示,在三维空间中的两个环绕区域,用户可以通过控制终端确定两个位置点,即一个环绕飞行起始位置点(如图5C中的5C1)和环绕飞行结束位置点(如图5C中的5C2),控制终端将这两个位置点发送给无人机,无人机在完成对一个目标对象的环绕飞行后,从所述一个目标对象的环绕飞行结束位置点向下一目标对象的环绕飞行起始位置点,在某些实施例中,控制无人机以直线的方式从所述一个目标对象的环绕飞行结束位置点向下一目标对象的环绕飞行起始位置点。
需要说明的是,所述两个环绕区域可以不在同一个水平面。
第四种可行方式:所述轨迹信息包括一个或多个航点信息,在完成对一个目标对象的环绕飞行后向下一个目标对象飞行的过程中,根据所述航点信息向所述下一个目 标对象飞行。具体地,轨迹信息可以包括用户通过控制终端设置的一个或多个航点,如图5D所示,控制终端将所述一个或多个航点信息(例如,图5D中的5D1、5D2为确定的航点)发送给无人机,无人机完成了对一个目标对象的环绕飞行后向下一个目标对象飞行时,无人机会遍历所述一个或多个航点信息指示的航点。其中,无人机遍历所述航点信息指示的航点的轨迹可以通过预设的轨迹生成算法实现,例如直线拟合、多项式拟合等,在本申请实施例中并不做具体限定。
在本实施例中,结合附图5A至附图5D针对不同的拼接航段的轨迹信息,对根据对应的拼接航段的轨迹信息指示的轨迹控制无人机向所述下一个目标对象飞行进行详细说明。
基于附图2公开的目标对象A、B、C和D,以及基于表1中公开的环绕飞行信息,以及基于附图5A至附图5D公开的不同的拼接航段的轨迹信息,本实施例公开了如图6所示的针对目标对象A、B、C和D进行作业时,控制终端控制无人机进行飞行的一应用实例。
在图6中,H点为无人机的起始位置,无人机所要进行作业飞行的目标对象为A、B、C和D。控制终端分别对上述目标对象A、B、C和D的环绕飞行信息进行确定,得到目标对象A的环绕飞行信息包括:环绕飞行起始位置点为PA,逆时针旋转,具有环绕初始半径和环绕速度,但是没有环绕半径的变化率和垂直方向上的速度。因此,针对目标对象A的环绕可以生成一个逆时针旋转的标准的圆形环绕轨迹。
得到目标对象B的环绕飞行信息包括:环绕飞行起始位置点为PB,顺时针旋转,具有环绕初始半径、环绕速度和环绕半径的变化率。因此,针对目标对象B的环绕可以生成一个顺时针旋转的渐开线的环绕轨迹。
得到目标对象C的环绕飞行信息包括:环绕飞行起始位置点为PC,逆时针旋转,具有环绕初始半径、环绕速度和垂直方向的环绕速度。因此,针对目标对象C的环绕可以生成一个逆时针旋转的螺旋线的环绕轨迹。
得到目标对象D的环绕飞行信息包括:环绕飞行起始位置点为PD,顺时针旋转,具有环绕初始半径、环绕速度和环绕半径的变化率。因此,针对目标对象D的环绕可以生成一个逆时针旋转的渐开螺旋的环绕轨迹。
控制终端分别对目标对象A与目标对象B,目标对象B与目标对象C,目标对象C和目标对象D之间的拼接航段的轨迹信息进行确定。在本实施例中,目标对象A与目标对象B之间的轨迹信息可以为内切轨迹信息,目标对象B与目标对象C之间的轨迹 信息可以为目标对象B的环绕飞行技术位置点和目标对象C的环绕飞行起始位置点。目标对象C和目标对象D之间的轨迹信息可以为一个或多个航点信息。
控制终端在确定各个目标对象的环绕飞行信息,以及各个目标对象之间的拼接航段信息之后,开始根据上述环绕飞行信息和拼接航段信息控制无人机进行飞行。具体过程为:
控制终端控制无人机从起始位置H点飞向目标对象A。然后,根据目标对象A的环绕飞行信息执行环绕飞行,并在完成对目标对象A的环绕飞行之后,控制终端根据内切轨迹信息指示的轨迹控制无人机飞向目标对象B的环绕飞行起始位置点PB点。然后,控制终端控制无人机从起始位置点PB点开始,根据目标对象B的环绕飞行信息执行环绕飞行,并在完成对目标对象B的环绕飞行之后,将该环绕飞行轨迹的终止点作为目标对象B和目标对象C之间的拼接航段段的起始点,控制终端控制无人机从目标对象B的环绕飞行结束位置点飞向目标对象C的环绕飞行起始位置点PC点。然后,控制终端控制无人机从该起始位置点PC点开始,根据目标对象C的环绕飞行信息执行环绕飞行,并在完成对目标对象C的环绕飞行之后,遍历用户确定的一个或多个航点信息指示的航点飞向目标对象D的环绕飞行起始位置点PD,然后从开始起始位置点PD根据目标对象D的环绕飞行信息执行环绕飞行。
基于附图5A至附图5D公开的不同的拼接航段的轨迹信息,本实施例公开了如图7所示的针对目标对象E、F和G进行作业时,控制终端控制无人机进行飞行的另一应用实例。
在本实施例中,如图7所示,目标对象E、F和G所对应的环绕区域重叠。控制终端确定目标对象E、F和G所对应的环绕区域均通过外切拼接的方式构造航线段。其中,目标对象E上的E1为环绕飞行起始位置,E2为终止位置,E2同时也是目标对象E和目标对象F之间的拼接航段的起始位置。目标对象F上的F1为环绕飞行起始位置,同时也是目标对象E和目标对象F之间的拼接航段的终止位置。F2为环绕飞行的终止位置,同时也是目标对象F和目标对象G之间的拼接航段的起始位置。目标对象G上的G1为环绕飞行起始位置,同时也是目标对象F和目标对象G之间的拼接航段的终止位置,G2则为环绕飞行的终止位置。
如图7所示,最终确定的目标对象E、F和G各自的环绕飞行轨迹和拼接航段段的轨迹为:目标对象E的环绕飞行轨迹为E1-E2,目标对象E和目标对象F对应的环绕区域之间的拼接航段段的轨迹为E2-F1;目标对象F的环绕飞行轨迹为F1-F2,目 标对象F和目标对象G对应的环绕区域之间的拼接航段段的轨迹为F2-G1;目标对象G的环绕飞行轨迹为G1-G2。
基于上述本实施例公开的控制终端的控制方法,控制终端根据上述确定的目标对象各自的环绕飞行轨迹和拼接航段段的轨迹进行飞行,可以实现对目标对象E、F和G的掠飞飞行,从而能够满足在目标对象对应的环绕区域重叠时对无人机的应用需求,提高了无人机应用的灵活性和扩展性。
在某些实施例中,在对目标对象进行环绕飞行的过程,控制终端可以向无人机发送控制指令以对无人机的姿态、飞行速度、云台姿态、无人机的拍摄设备的工作状态中的一种或多种进行控制。
在某些实施例中,在完成对一个目标对象的环绕飞行后向下一个目标对象飞行的过程中,控制终端可以向无人机发送控制指令以对无人机的姿态、飞行速度、云台姿态、无人机的拍摄设备的工作状态中的一种或多种进行控制。
在某些实施例中,在控制终端控制无人机对最后一个目标对象进行环绕飞行之后,可以根据控制终端设置的预设策略执行相应地操作(如悬停、返航、降落等)。
在某些实施例中,控制终端控制目标对象环绕飞行的过程中,确定更新的环绕飞行信息,控制终端根据更新的环绕飞行信息控制无人机对所述目标对象进行环绕飞行。具体地,在无人机对目标对象进行环绕飞行的过程中,用户可以通过控制终端确定更新的环绕飞行信息,将所述环绕飞行信息发送给无人机,无人机即可以根据更新的环绕飞行信息对所述目标对象进行环绕飞行。
在某些实施例中,控制终端在完成控制一个目标对象的环绕飞行后向下一个目标对象飞行的过程中,确定更新的拼接航段信息;控制终端根据更新的拼接航段信息控制无人机向下一个目标对象飞行。
在某些实施例中,控制终端在控制无人机飞行过程中,向无人机发送控制指令,所述控制指令用于对无人机的云台或拍摄设备进行控制。
