具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获 得的所有其他实施例,都属于本发明保护的范围。
本发明的实施例提供了航线修正的方法、设备和无人机。以下对本发明的描述使用无人机作为示例。对于本领域技术人员将会显而易见的是,可以不受限制地使用其他类型的无人机,本发明的实施例可以应用于各种类型的无人机。例如,无人机可以是小型或大型的无人机。在某些实施例中,无人机可以是旋翼无人机(rotorcraft),例如,由多个推动装置通过空气推动的多旋翼无人机,本发明的实施例并不限于此,无人机也可以是其它类型的无人机。
如图1所示,是本发明实施例的一种无人机系统的示意图,该系统包括作为地面端遥控设备的控制终端101和无人机102,所述控制终端101可以为专用遥控器、智能手机、平板电脑、无人机地面控制站、手表、手环、视频眼镜等中的一种或多种。
无人机102飞行的路线称之为航线,航线中包括了多个航点,将多个航点称为航点序列,在本发明实施例中,在无人机飞行前,控制终端101向用户呈现包括某个目标区域的地图的交互界面,用户根据需要可以在地图上打点,这些点即为航点。在航线数据中,航点以坐标的形式存在。在某些情况下,航点除包括坐标以外还可以包括:航点的索引ID、航点动作信息、与该航点相关联的航线属性等,其中航点动作包括但不限于云台控制信息、拍摄控制信息,其中与该航点相关联的航线属性可以包括但不限于直线飞行模式、协调转弯模式、POI等飞行模式。
控制终端101将用户在交互界面的地图上打点的位置确定为航点,航点坐标可以是这些点的GPS位置坐标,而航点的飞行高度则可以为默认的高度值。当然用户也可以根据需要和地图上实际位置的海拔高度,来在控制终端101中动态配置一个或者多个航点的高度。航线的设置还可以有其他方式,例如,用户仅仅在控制终端101中输入几个位置的坐标作为航点。控制终端101会根据用户输入的多个航点确定一条航点。
控制终端101将生成的航线会发送给无人机102,无人机102在接收到航线后,会执行航线。具体的,无人机102中的控制器根据航线中包括的各个航点,控制无人机102依次飞向这些航点,实现在航线上飞行。
应理解,上述对于无人机系统各组成部分的命名仅是出于标识的目的, 并不应理解为对本发明的实施例的限制。
图2为本发明实施例提供的航线修正的方法的流程图,如图2所示,本实施例的方法应用于无人机中,可以包括:
S201、获取对航线的修正数据。
S202、根据所述修正数据对航线进行修正以得到修正后的航线。
S203、控制无人机在修正后的航线上飞行。
本实施例中的航线可以是用户预先在控制终端上设定好的,并存储在无人机中,无人机在飞行的时候,按照该航线进行飞行。在无人机按照航线飞行的过程中,无人机的飞行可能会受到各种各样的干扰(例如环境中的障碍物、风、光照等),而对无人机的安全飞行或者无人机需要执行的任务产生影响,因此在本实施例,无人机可以获取对航线产生影响的数据,此数据用于对航线进行实时地修正,以保证无人机的飞行效果,此数据可称为对航线的修正数据,然后根据该航线的修正数据对航线进行修改,即根据所述航线修正数据对航线中的每一个航点的位置信息进行修正,从而获得修正后的航线,然后控制无人机在修正后的航线上飞行。其中航点的位置信息包括经度、纬度、高度中的至少一种。
本实施例中,通过获取对航线的修正数据,并根据所述航线的修正数据对航线进行修正以得到修正后的航线,然后再控制无人机在修正后的航线上飞行,实现了对航线的实时修正,达到无人机按照修正后的航线飞行的目的,提高无人机执行航线的灵活性,另外,在本实施例中,当用户需要对航线进行修正时,用户无需对航线中每一个单独的航点进行单独的编辑和操作,在无人机获取航线的修正数据后,无人机可以根据航线的修正数据对航线中的每一个航点的位置信息进行修正,简化了操作流程。
可选地,所述根据所述修正数据对航线进行修正以得到修正后的航线包括:在无人机的执行航线的过程中,根据所述修正数据对未被无人机执行的航线进行修正以得到修正后的航线。
其中,在无人机的执行航线的过程中,无人机已经按照该航线进行了飞行,则该航线可以分成两部分:一部分为该航线中已经被无人机执行的航线,另一部分为该航线中还未被无人机执行的航线。而在本实施例中,当无人机在飞行过程中,即在无人机已经执行了预设设定的航线中的一部分航线时, 在获取到对该航线的修正数据后,无人机可以根据该修正数据对未被无人机执行的航线进行修正,即无人机可以根据所述航线的修正数据对未被无人机执行的航线中的每一个航点进行修正,然后再控制无人机在修正后的未被无人机执行的航线上飞行。本实施例中,在无人机执行航线的过程中,当用户想要对未被无人机执行的那一部分航线进行修正时,用户可以操作控制终端,对该部分航线进行修正,这样提高了航线修正的灵活性。
可选地,所述修正数据为航线的高度修正数据;所述根据所述航线修正数据对航线进行修正以得到修正后的航线包括:根据所述航线的高度修正数据对航线的高度信息进行修正以得到修正后的航线。
其中,本实施例对航线修正的一种可行的实现方式为对航线的高度进行修正,因此,上述实施例中的修正数据为航线的高度修正数据。具体地,本实施例可以获取对航线的高度产生影响的数据,此处称为该航线的高度修正数据,然后根据该航线的高度修正数据对航线的高度信息进行修正,即可以对航线或者未被无人机执行的航线中的每一个航点的高度进行修正,从而获得高度修正后的航线。本实施例中再控制无人机在具有新的高度信息的修正后的航线上飞行,从而实现了实时、动态地修正航线的高度。
可选地,本实施例的方法还包括:在获取对航线的高度修正数据之前,接收控制终端发送的高度模式控制信息,根据所述高度模式控制信息确定航线的高度信息修正模式。所述根据所述航线的高度修正数据对航线的高度信息进行修正以得到修正后的航线包括:在确定的航线的高度信息修正模式中,根据所述航线的高度修正数据对航线的高度信息进行修正以得到修正后的航线。
其中,在对航线的高度信息进行修正的过程中,可以预先确定航线的高度信息修正模式,不同的高度信息修正模式对应的修正航线的高度信息的具体过程不同,例如:对于同一高度修正数据,若高度信息修正模式为绝对高度修正模式,则修正的是航线的绝对高度,若高度信息修正模式为相对高度修正模式,则修正的是航线的相对高度,本实施例中的高度信息修正模式不限于上述两种。因此,在确定好高度信息修正模式后,并在该高度信息修正模式下对航线的高度信息进行修正,可以保证航线的高度信息的修正准确性,避免了修正后的航线达不到用户所需的效果的缺陷。因此,本实施例在获取 对航线的高度修正数据之前,用户通过操作控制终端设置高度信息修正模式,相应地,无人机可以接收控制终端根据用户的操作而发送的高度模式控制信息,然后根据该高度模式控制信息确定航线的高度信息修正模式。
可选地,所述接收控制终端发送的模式控制信息,根据所述高度模式控制信息确定航线的高度信息修正模式包括:接收控制终端发送的第一高度模式控制信息,根据所述第一高度模式控制信息确定航线的绝对高度信息修正模式。相应地,所述在确定的航线的高度信息修正模式中,根据所述航线的高度修正数据对航线的高度信息进行修正以得到修正后的航线包括:在所述绝对高度信息修正模式中,所述高度的修正数据为高度偏移量,将所述航线中的航点的高度值分别与所述高度偏移量叠加以得到修正后的航线。
其中,当用户需要通过控制终端设置高度信息修正模式为绝对高度信息修正模式时,本实施例可以接收控制终端根据用户的操作发送的第一高度模式控制信息,该第一高度模式控制信息用于指示高度信息修正模式为绝对高度信息修正模式,因此,本实施例中根据该第一高度模式控制信息可确定绝对高度信息修正模式。在这种情况下,获取到的高度修正数据即为高度偏移量,然后本实施例在上述确定的绝对高度信息修正模式中,将航线中的航点的高度值分别与该高度偏移量相加,从而获得各航点新的高度值,因此,在新的高度值下的各航点可以形成修正后的航线。
图3为本发明实施例提供的对航线的高度进行修正的一种示意图,如图3所示,以当前的高度信息修正模式为绝对高度信息修正模式,当无人机在飞行的过程中,即无人机已经执行了航线中的部分航线时,用户想对还未被无人机执行的部分航线的绝对高度进行修正时,用户可以通过对控制终端的交互界面进行操作,例如利用控制终端的交互界面输入一个高度偏移量,无人机飞行向航点A飞行时,获取到所述高度偏移量,例如为h1,图3示出的例子以航点A与航点B的高度值相同为例,需要说明的是,未被无人机执行的航线的各个航点的高度值可以不同,而且也不限于上述两个航点。而且航线中的航点A与航点B的高度值为h2(以相对于地面的高度为例),然后将航点A的高度和航点B的高度修正为h1+h2,修正高度后的航点A与航点B形成了修正后的航线,修正后的航线比修正前的航线的高度偏移了h1,从而将无人机从在高度值为h2的高度飞行调整为在高度值为h1+h2的高度飞行。 虽然图3示出了以增加高度为例,但也可以对各航点的高度进行降低处理。
可选地,所述获取航线的修正数据包括:接收所述控制终端发送的高度控制杆量,根据所述高度控制杆量确定高度偏移量,其中所述高度控制杆量是通过操作控制终端的特定摇杆产生的。
其中,在高度信息修正模式为绝对高度信息修正模式下,获取航线的修正数据的一种方式为:用户可以通过操作控制终端的特定摇杆设置高度偏移量,即在无人机飞行的过程中,用户想要对未被无人机执行的部分航线进行绝对高度修正时,用户可以操作控制终端的特定摇杆,当用户操作该摇杆时,本实施例中的无人机可以接收控制终端发送的由用户的操作产生的高度控制杆量,无人机可以根据所述高度控制杆量确定高度偏移量,根据高度偏移量对航线或未被无人机执行的部分航线进行绝对高度修正。其中,用户对特定摇杆不同的操作会产生不同的高度控制杆量,而且高度控制杆量与高度偏移量存在对应关系,例如无人机可以将高度控制杆量通过特定的方式换算得到高度偏移量,因此,本实施例接收到高度控制杆量后,根据该高度控制杆量可以确定高度偏移量。
可选地,特定摇杆可以为控制终端的油门杆。
可选地,所述获取航线的修正数据包括:接收通过所述控制终端上的交互界面输入的高度偏移量。
其中,在高度信息修正模式为绝对高度信息修正模式下,获取航线的修正数据的一种方式为:用户可以通过操作控制终端的交互界面设置高度偏移量,其中交互界面可以是触摸显示屏,例如:若用户需要将航线的高度升高5m,则用户可以在该交互界面中输入高度偏移量为5m。若用户需要将航线的高度降低5m,则用户可以在该交互界面中输入高度偏移量为-5m。相应地,本实施例可以接收控制终端发送的用户在交互界面上输入的高度偏移量。
可选地,所述将所述航线中的航点的高度值分别与所述高度偏移量叠加以得到修正后的航线包括:当所述高度偏移量在预设的偏移量范围内时,将所述航线中的航点的高度值分别与所述高度偏移量叠加以得到修正后的航线;当所述高度偏移量在预设的偏移量范围之外时,向控制终端发送拒绝对航线的高度进行修正的信息。
其中,具体的,当用户通过控制终端确定的高度偏移量过大,有可能修 改后的航线高度超过无人机安全飞行的范围而影响飞行安全,或者,因为障碍物的存在而无法将航点的高度偏移该高度偏移量,或者,若高度偏移量过小,无人机的传感系统不能感知高度偏移量,而且高度偏移量太小不足以使航点的高度的修正带来有效性改变,例如高度偏移量为1cm,无人机的传感系统最小的测量距离可能大于1cm,这种过小的高度修正将没有意义,还浪费处理资源。因此,本实施例中在无人机获取到高度偏移量之后,判断该高度偏移量或者修正后的航线的高度是否在预设的范围内,当该高度偏移量或者修正后的航线的高度在预设的范围内时,说明可以对高度进行修正,然后将航点的高度值分别与高度偏移量叠加以得到修正后的航线。当该高度偏移量或者修正后的航线的高度不在预设的偏移量范围内时,说明不能对高度进行修正,然后向控制终端发送拒绝对航线的高度进行修正的信息,可选地,所述拒绝对航线的高度进行修正的信息还可以指示拒绝的原因,例如:高度偏移量过大或者过小,或者修正后的航线的高度超出安全飞行的高度等。需要说明的是,预设的偏移量范围可以是固定不变的,也可以是随着无人机的飞行环境而改变,例如:当无人机的传感系统感知到无人机离地面10m时,则预设的偏移量范围包括:高度偏移量应大于-10m,当无人机离地面20m时,则预设的偏移量范围包括:高度偏移量应大于-20m。
可选地,所述接收控制终端发送的模式控制信息,根据所述模式控制信息确定航线的高度信息修正模式包括:接收控制终端发送的第二模式控制信息,根据所述第二模式控制信息确定航线的相对高度信息修正模式。相应地,所述在确定的航线的高度信息修正模式中,根据所述航线的高度修正数据对航线的高度信息进行修正以得到修正后的航线包括:在所述相对高度信息修正模式中,所述高度的修正数据为期望相对高度,其中,所述期望相对高度是无人机相对于参考点的期望相对高度;利用无人机的传感系统确定无人机相对于所述参考点的实际高度;根据所述期望相对高度和所述实际高度修正航线的高度以得到修正后的航线。
其中,当用户需要通过控制终端设置高度信息修正模式为相对高度信息修正模式时,无人机例可以接收控制终端根据用户的操作发送的第二高度模式控制信息,该第二高度模式控制信息用于指示高度信息修正模式为相对高度信息修正模式,因此,本实施例中根据该第二高度模式控制信息可确定相 对高度信息修正模式。在这种情况下,获取到的高度修正数据即为期望相对高度,该期望相对高度是无人机在执行航线的过程中无人机相对于参考点的期望相对高度。然后本实施例在上述确定的相对高度信息修正模式中,本实施例利用无人机的传感系统确定无人机相对于所述参考点的实际高度,然后根据期望相对高度和实际高度对航线的高度进行修正,从而可以形成修正后的航线。
图4为本发明实施例提供的对航线的高度进行修正的另一种示意图,如图4所示,以当前的高度信息修正模式为相对高度信息修正模式,图4中示出的参考点以地面为例,作为参考点的地面具有一个凸起。本实施例获取到期望相对高度之后,利用无人机的传感系统确定无人机相对与地面的实际高度,然后根据该期望相对高度和实际高度修正航线的高度,即在无人机遍历航线或者未被无人机执行的航线中每一个航点时,使得航线中的航点相对于无人机下方的地面的距离为期望相对高度,这样形成的修正后的航线随着地面的地形的改变始终保持与地面的相对距离为该期望相对高度,修正后的航线与修正前的航线的相比,产生了变化,根据图4所示的修正后的航线,无人机可以实现自动爬高或降低的地形跟随(防地飞行)功能。
可选地,所述实际高度是在预设时间段内或在预设的距离内无人机相对参考点的高度平均值。
可选地,所述参考点包括无人机下方的地面、建筑、水面、植被、移动物体中的一种或多种。其中,移动物体可以为人或者车等。
可选地,所述获取航线的修正数据包括:接收通过所述控制终端上的交互界面输入的期望相对高度。
其中,在高度信息修正模式为相对高度信息修正模式下,获取航线的修正数据的一种方式为:用户可以通过操作控制终端的交互界面设置期望相对高度,例如:若用户需要将无人机飞行的航线与参考点之间相对的期望相对高度设置为20m,相应地,本实施例可以接收控制终端发送的用户在交互界面上输入的期望相对高度。
可选地,所述根据所述期望相对高度和所述实际高度修正航线的高度以得到修正后的航线包括:当所述期望相对高度位于所述传感系统的探测范围内时,根据所述期望相对高度和所述实际高度修正航线的高度以得到修正后 的航线;当所述期望相对高度位于所述传感系统的探测范围之外时,向控制终端发送拒绝对航线的高度进行修正的信息。
其中,若期望相对高度过大,有可能超过无人机的传感系统有效探测的最大探测范围而影响飞行安全,而且期望高度过大可能导致修正后的航线高度超过无人机的安全飞行高度;另外若期望相对高度过小,也有可能超过了传感系统的最小探测范围,而且期望相对高度过小可能导致无人机离参考点之间的距离过小而与参考点发生碰撞。因此,本实施例中,无人机在获取到期望相对高度之后,判断该期望是否在传感系统的探测范围内,当该期望相对高度在传感系统的探测范围时,说明可以对高度进行修正,然后根据期望相对高度和实际高度修正航线的高度以得到修正后的航线。当该期望相对高度不在传感系统的探测范围内时,说明不能对高度进行修正,然后向控制终端发送拒绝对航线的高度进行修正的信息,可选地,该拒绝对航线的高度进行修正的信息还可以指示拒绝的原因,例如:期望相对高度过大。
可选地,所述修正数据为航线的水平位置修正数据。所述根据所述航线的修正数据对航线进行修正以得到修正后的航线包括:根据所述航线的水平位置修正数据在水平面上移动所述航线以得到修正后的航线。
其中,本实施例对航线修正的一种可行的实现方式为对航线的水平位置进行修正,因此,上述实施例中的修正数据为航线的水平位置修正数据。具体地,本实施例可以获取对航线的水平位置产生影响的数据,此处称为该航线的水平位置修正数据,然后根据该航线的水平位置修正数据对航线在水平面上进行移动,即根据航线的水平位置修正数据在水平方向上对航线或未被无人机执行的航线中的每一个航点进行水平移动,保持航点的高度不变,从而获得修正后的航线,修正后的航线在水平面上具有新的位置,且修正后的航线的水平位置与修正前的航线的水平位置不同,同时保持航线的高度不变。本实施例中再控制无人机在具有新的水平位置的修正后的航线上飞行。从而实现了实时、动态地修正航线的水平位置。
可选地,所述获取航线的修正数据包括:接收通过所述控制终端上的交互界面输入的航线的水平位置修正数据。
其中,获取航线的水平位置修正数据的一种方式为:用户可以通过操作控制终端的交互界面设置水平位置修正数据,相应地,无人机可以接收控制 终端发送的用户在交互界面上输入的水平位置修正数据。可选地,水平位置修正数据包括:水平移动方向和/或水平移动距离。例如:若用户需要将航线往左移动10m,则用户输入水平移动方向和水平移动距离;若水平移动方向固定,则用户向交互界面输入水平移动距离即可;若水平移动距离固定,则用户向交互界面输入水平移动方向。相应地,本实施例可以接收控制终端发送的用户在交互界面上输入的水平位置修正数据。
可选地,所述获取航线的修正数据包括:根据无人机的传感系统采集的数据确定航线的水平位置修正数据。
其中,获取航线的水平位置修正数据的一种方式为:无人机的传感系统可以采集对无人机的航线飞行有影响的环境信息,当无人机沿着所述航线飞行时,这些环境信息可能会对无人机的飞行安全或者所执行的特定任务产生影响,因此,本实施例可以通过传感系统采集的数据确定出航线的水平位置修正数据,根据所述航线的水平位置修正数据对航线的水平位置进行修正,以保证在环境因素的影响下也能保证无人机飞行的安全或执行特定的任务。可选地,所述水平位置修正数据至少包括水平移动方向和/或水平移动距离。其中,水平移动方向指示航线在水平面上移动修正的方向,水平移动距离表示航线在水平上移动修正的距离。
可选地,所述根据无人机的传感系统采集的数据确定航线的水平位置修正数据包括:根据无人机的传感系统采集的风向数据和/或风速数据确定航线的水平位置修正数据。
本实施例中,当无人机执行航线时,环境中的风、光照方向等会对无人机执行的任务产生影响。具体的,此处以农田作业应用场景为例,无人机可用于向农田中喷撒药液,根据农田的地形预先设置航线,无人机按照该航线飞行可以将药液均匀地喷撒在整个农田中,但是这种效果是在无风的情况下。若一旦环境中起风了,药液在风的影响下会产生偏移进而会影响到药液的沉降轨迹,影响到药液的喷撒效果。因此,需要在无人机在按照航线喷撒药液的过程中,实时根据风来修正航线,以使得药液均匀沉降在农田中,改善药液喷撒效果。而且无人机的传感系统采集风向数据和/或风速数据,风向数据可以影响到药液的沉降偏移方向,风速数据可以影响到药液的沉降偏移距离,因此,无人机根据风向数据和/或风速数据确定航线的水平位置修正数据。
可选地,所述根据无人机的传感系统采集的风向数据和/或风速数据确定航线的水平位置修正数据包括:根据无人机的传感系统采集的风向数据确定航线的水平移动方向,根据无人机传感系统采集的风速数据确定水平移动距离。
其中,以无人机喷撒药液为例,若风向数据指示风向朝南吹,药液由无人机喷出后,药液在风的作业下,会朝南偏移,这样使得药液向南偏移了预设的沉降轨迹,因此,需要将航线的水平移动方向向北移动,所以根据无人机的传感系统采集的风向数据确定航线的水平移动方向。而且风速的大小会影响到药液的偏移预设的沉降轨迹的距离,因此,根据药液的偏移的距离,修正航线的水平移动距离,以使得药液准确地落在预设的沉降轨迹上,所以根据无人机的传感系统采集的风速数据确定航线的水平移动距离。
图5为本发明实施例提供的修正航线的水平位置的一种示意图,如图5所示,以X轴指向为北向,以Y轴指向为东向为例,无人机的传感系统采集到的风向数据为西北风向(该风向与北向的夹角为45度),风速数据为1m/s。根据风向数据为西北风向,确定航线的水平修正方位为朝东南方位。由于风速数据为1m/s,而且无人机喷撒的药液需要5s的时间才能落地,因此药液在空中要被风影响的时间为5s,由于风速为1m/s,因此,药液在风的影响在水平面上会偏移1m/s×5s=5m,由此可知,航线的水平修正距离d为5m。然后根据风向与X轴的夹角为45度,可以确定航线沿X轴偏移的距离dx(朝南偏移),确定航线沿Y轴偏移的距离dy(朝东偏移),然后据此对航线进行偏移,从而获得如图5所示的修正后的航线。无人机在修正后的航线上飞行,即使在风的影响下,药液也能沉降在预设的沉降轨迹上。其中,坐标系的原点可以是无人机当前的目标航点。
可选地,所述根据无人机的传感系统采集的数据确定航线的水平位置修正数据包括:根据无人机的传感系统采集的障碍物信息确定航线的水平位置修正数据。
本实施例中,当无人机执行航线时,环境中的障碍物可能会对无人机的飞行安全性产生影响,若障碍物位于无人机的航线区域内时,会对飞行安全产生影响。在包含复杂地形(如水域、山林等)的航线区域的应用场景中,难以对整个航线进行事先的探测,规划好的航线区域中不排除会存在障碍物, 一般只有在无人机靠近障碍物之后才会发现障碍物是否影响到了航线。因此,无人机执行航线飞行过程中,会通过传感系统实时感测障碍物,以获取障碍物信息,为了避免障碍物对航线的影响,影响无人机的飞行安全,本实施例利用无人机的传感系统采集的障碍物信息来确定航线的水平位置修正数据。
可选地,所述根据无人机的传感系统采集的障碍物信息确定航线的水平位置修正数据包括:根据无人机的传感系统采集到的障碍物的距离和/或方位确定航线的水平位置修正数据。
图6为本发明实施例提供的修正航线的水平位置的另一种示意图,如图6所示,以X轴指向为北向,以Y轴指向为东向为例,无人机的传感系统在图中所示的位置检测到障碍物。为了保证飞行安全,需要对航线进行修正。因此,根据无人机的传感系统获取无人机的当前位置与障碍物之间的距离,如图6所示距离为d,另外还获取障碍物的方位,即可以获取障碍物与无人机沿当前航线飞行方向之间的夹角为α。还获取无人机当前的目标航点与无人机的当前位置之间的距离,如图6所示距离为d1。然后根据距离d和夹角α,确定障碍物在当前航线上的投影位置与无人机的当前位置之间的距离为d2=dcosα。然后,确定航线的水平移动距离和水平移动方向。可选地,当d2-d1大于预设距离时,可以确定不需要修正航线的水平位置,当d2-d1小于或等于预设距离时,确定需要修正航线的水平位置,其中,航线的水平移动距离依据d2-d1决定,或者,航线的水平移动距离为默认的距离,或者航线的水平移动距离为无人机到障碍物之间的距离,本实施例不限于此。可选地,航线的水平移动方向可以是:无人机沿当前航线飞行方向的反方向,或者,无人机的当前位置到障碍物的方向的反方向(即与无人机的传感系统采集到的障碍物的方位相反的方位),本实施例不限于此。其中,图6中示出了水平位置移动距离为固定距离Δd,水平位置移动方位为无人机沿当前航线飞行方向的反方向。然后据此对航线进行偏移,从而获得如图6所示的修正后的航线。无人机在修正后的航线上飞行,保证了飞行安全。
图7为本发明实施例提供的修正航线的水平位置的另一种示意图,如图7所示,以X轴指向为北向,以Y轴指向为东向为例,其中坐标系的原点为当前无人机的目标航点,如果,无人机的传感系统在图7中所示的位置采集到障碍物信息,为了保证飞行安全,需要对航线进行修正,因此,获取无人 机的当前位置与当前目标航点之间的距离,将所述距离作为航线的水平位置修正距离,将当前目标航点到当前位置之间的移动方向作为航线的水平位置修正方向,如图7所示,水平位置修正距离为dx,水平位置修正方位为朝南,然后据此对航线进行偏移,从而获得如图7所示的修正后的航线。
在某些实施方式中,当无人机一旦探测到障碍物信号时,无人机的传感系统获取障碍物相对于无人机的方位和距离,则可以按照与所述方位相反的方位水平移动航线,其中移动的距离为当前无人机到障碍物之间的距离,无人机在修正后的航线上飞行,避免了障碍物落入飞行区域内,保证了飞行安全。
可选地,所述航线的修正数据为航线的旋转修正数据。所述根据所述修正数据对航线进行修正包括:根据所述航线的旋转修正数据对航线进行水平旋转以得到修正后的航线。
其中,本实施例对航线修正的一种可行的实现方式为对航线的进行旋转修正。因此,上述实施例中的修正数据为航线的旋转修正数据。具体地,本实施例可以获取对航线的旋转产生影响的数据,此处称为该航线的旋转修正数据,然后根据该航线的旋转修正数据对航线在水平面上进行旋转,即根据所述航线的旋转修正数据对航线或未被无人机执行的航线中的每一个航点进行说明旋转,从而获得修正后的航线。即根据航线的旋转修正数据对航线进行旋转,使得修正后的航线在水平面上相对于原航线旋转了一定的角度,从而实现了实时、动态地对航线进行旋转。
可选地,所述航线的旋转修正数据包括航线的指定旋转中心和/或航线的旋转量。指定旋转中心用于指示航线在水平面上旋转的中心点,即航线以该中心点为中心对航线进行水平旋转修正,航线的旋转量用于指示航线在水平面上旋转的角度。
可选地,所述获取航线的修正数据包括:接收控制终端发送的航线的指定旋转中心和/或航线的旋转量。所述根据所述航线的旋转修正数据对航线进行水平旋转以得到修正后的航线包括:根据所述航线的指定旋转中心和/或所述航线的旋转量对航线进行水平旋转以得到修正后的航线。
其中,获取航线的水平位置修正数据的一种方式为:用户可以通过操作控制终端设置指定旋转中心和/或航线的旋转量,相应地,无人机可以接收控 制终端发送的用户通过控制终端的交互界面上输入的指定旋转中心和/或航线的旋转量。例如:用户可以输入指定旋转中心和旋转量,指定旋转中心可以是用户从航线中确定的其中一个航点,其中所述航点可以为未被无人机执行的航线中的任意一个航点,旋转量例外如为30度。若指定旋转中心固定或者为默认航点,则用户只需输入旋转量即可;若旋转量固定,则用户只需输入指定旋转中心。相应地,本实施例可以接收控制终端发送的指定旋转中心和/或航线的旋转量,然后根据旋转中心和/或旋转量对航线进行水平旋转。
可选地,所述获取航线的修正数据包括:获取控制终端发送的航线的旋转量。所述根据所述航线的旋转修正数据对航线进行水平旋转以得到修正后的航线包括:以无人机当前的目标航点为航线的旋转中心,根据所述旋转中心和所述航线的旋转量对航线进行水平旋转以得到修正后的航线。
其中,航线的旋转中心是根据预设规则确定的,无需通过控制终端来获取,该航线的旋转中心为无人机当前的目标航点,即无人机即将飞向的下一个航点。无人机只需要从控制终端处获取航线的旋转量即可,该航线的旋转量可以是用户通过控制终端的交互界面输入的。本实施例在获取到航线的旋转量后,以无人机当前的目标航点为航线的旋转中心进行水平旋转所述旋转量,从而形成修正后的航线。
可选地,所述获取航线的修正数据包括:根据无人机的传感器系统采集的风向数据确定航线的旋转量;所述根据所述航线的旋转修正数据对航线进行水平旋转以得到修正后的航线包括:以无人机当前的目标航点为航线的旋转中心,根据所述旋转中心和所述航线的旋转量对航线进行水平旋转以得到修正后的航线。
其中,环境中的风会对无人机的飞行或航线产生影响,以无人机执行航线的飞行过程中,若无人机逆风飞行,由于风的作用使得无人机受到的阻力越大,在达到相同飞行速度时,需要消耗更多的动力资源,因此,理想的状态是,无人机能顺风飞行,这样可以节省动力资源。而且,无人机的传感系统可以采集到风向数据,因此,本实施例可以根据采集的风向数据确定航线的旋转量,例如:可以根据无人机当前的飞行方向和风向数据,确定使无人机顺风飞行的航线的旋转量。然后以无人机当前的目标航点为航线的旋转中心,将航线在水平面上旋转所述旋转量,从而得到修正后的航线。其中,无 人机也可以以用户通过控制终端指定的航点为旋转中心。此处不做具体的限定。
可选地,所述获取航线的修正数据包括:根据无人机的传感器系统采集的光照方向数据确定航线的旋转量。所述根据所述航线的旋转修正数据对航线进行水平旋转以得到修正后的航线包括:以无人机当前的目标航点为航线的旋转中心,根据所述旋转中心和所述航线的旋转量对航线进行水平旋转以得到修正后的航线。
其中,当无人机执行航线时,环境中的光照方向对无人机执行的任务产生影响,在一些应用场景下,例如使用无人机沿航线飞行来对目标对象进行拍摄,如果无人机迎着光照方向对目标对象进行拍摄时,拍摄效果会较差,此时,无人机需要背光飞行,此时无人机可以对航线进行旋转,使得无人机沿修正后的航线飞行时是背光对目标对象进行拍摄。具体的,无人机的传感系统可以采集到光照方向,根据采集的光照数据确定航线的旋转量,例如:可以根据无人机当前的飞行方向和光照方向,确定的旋转量。然后以无人机当前的目标航点为航线的旋转中心,将航线在水平面上旋转所述旋转量,从而得到修正后的航线。其中,无人机也可以以用户通过控制终端指定的航点为旋转中心。此处不做具体的限定。
可选地,所述根据所述航线的旋转修正数据对航线进行水平旋转以得到修正后的航线包括;当所述航线的旋转中心和/或航线的旋转量在预设的范围内时,根据所述航线的旋转修正数据对航线进行水平旋转以得到修正后的航线;当所述航线的旋转中心的位置和/或航线的旋转量在预设的范围之外时,向无人机的控制终端发送拒绝航线旋转的信息。
其中,本实施例中,当无人机在获取到修正数据中的旋转中心,无人机会判断旋转中心的位置是否在预设的位置范围内,当用户选中的旋转中心在预设的位置范围内时,无人机才会认为用户选中的旋转中心是合法的旋转中心,当旋转中心和/或旋转量不在预设的位置范围内时,向控制终端发送拒绝对航线进行旋转的信息。另外,无人机还会对用户通过控制终端输入的旋转量进行合法性检测,当用户输入的旋转量输入的旋转量不在预设的旋转量的范围内时,无人机才会认为用户输入的旋转量是合法的旋转量,当旋转量不在预设的位置范围内时,无人机会判定该旋转量为非法旋转量,向控制终端 发送拒绝对航线进行旋转的信息。例如合法的旋转量范围在-180度-180度,当用户输入不在该范围内的旋转量时,无人机会拒绝对航线进行水平旋转修正。可选地,本实施例中的拒绝航线旋转的信息还可以指示拒绝的原因。

其中,无人机的传感系统包括超声波传感器、视觉传感器、激光传感器、TOF传感器、雷达、红外传感器、惯性测量单元、点阵传感器中的一种或多种。
本发明实施例中还提供了一种计算机存储介质,该计算机存储介质中存储有程序指令,所述程序执行时可包括如图2及其对应实施例中的航线修正的方法的部分或全部步骤。
