本申请实施例中涉及的无人机可以包括但不限于：动力系统、飞行控制系统、通信系统。其中，通信系统用于与控制设备建立通信链路，并基于建立的通信链路进行通信连接，接收控制设备的控制指令，或者向控制设备发送图像等数据。进一步地，通信系统可以将控制设备的控制指令发送至飞行控制系统，飞行控制系统可以根据该控制指令控制动力系统，以使动力系统为无人机提供飞行动力，实现无人机根据该控制指令进行飞行。
本申请实施例中涉及的信息传输装置可以是飞行器，也可以是飞行器中的装置，本申请实施例中对此并不作限制。
本申请实施例中涉及的控制设备可以包括但不限于：遥控器、终端或二者结合的地面站等设备。
本申请实施例中无人机与控制设备建立通信链路所基于的无线网络包括但不限于以下任一项：无线保真(WIreless-Fidelity，WIFI)、长期演进(Long Term Evolution，LTE)、点对点网络、数字广播网络等。其中，通过WIFI、数字广播、LTE可以实现一对多通信，即无人机可以与多个控制设备进行通信，无人机与多个控制设备中的每个控制设备建立一个通信链路，以实现无人机与控制设备之间的通信连接。点对点网络链路可以实现一对一通信，即无人机可以与一个控制设备进行通信，无人机与该控制设备通过一个信道进行通信。
其中，一个信道中可以包括一个或多个通信链路。
当实现一对多通信时，无人机可以利用一个信道建立多个通信链路，每个通信链路用于实现该无人机与一个控制设备之间的通信。或者，无人机可以利用一个信道建立一个通信链路，该通信链路用于实现该无人机与一个控制设备之间的通信。
当实现一对一通信时，一个无人机与对应的一个控制设备可以利用一个信道建立一个通信链路，以实现该无人机与该控制设备之间的通信。同时，另一个无人机也可以利用该信道建立与其对应的控制设备之间的通信链路。
对于无人机与控制设备建立通信链路，一种实现方式为：
无人机对信道进行扫描，从扫描出的信道中选取一个信道，并通过该信道 将建立连接的请求发送给控制设备，控制设备在该信道接收到建立连接的请求后，可以针对该请求发送连接响应，进而无人机与控制设备在该信道上建立通信链路，以实现相互通信。
本申请实施例中涉及的信息可以包括但限于以下至少一项：飞行数据、视频数据、图片数据、指令、文件等。
本申请实施例中涉及的同频干扰系数用于指示一个变量用于计算同频干扰量。
本申请实施例中涉及的邻频干扰系数用于指示一个变量用于计算邻频干扰量。
本申请实施例中涉及的任一信道对应的同频干扰信道是指带宽范围完全重叠的信道。
本申请实施例中涉及的任一信道对应的邻频干扰信道是指带宽范围部分重叠的信道。
本申请实施例中涉及的任一信道对应的安全信道距离是指该信道与其他信道之间互不干扰的最小信道距离。在此，频率差可以用于表示信道距离。示例性地，各通信链路的安全信道距离可以由对应的通信设备厂商确定，或者通过其它方式确定，本申请实施例中对此并不作限制。
示例性地，以WIFI为例进行说明：假设WIFI网络下存在信道1～11，其中，信道距离超过预设带宽，如20MHz，以上的信道之间不存在邻频干扰，各信道只存在同频干扰，则可以确定出如下内容：
信道1的干扰信道包括:信道1—信道5；
信道2的干扰信道包括:信道1—信道6；
信道3的干扰信道包括:信道1—信道7；
信道4的干扰信道包括:信道1—信道8；
信道5的干扰信道包括:信道1—信道9；
信道6的干扰信道包括:信道2—信道10；
信道7的干扰信道包括:信道3—信道11；
信道8的干扰信道包括:信道4—信道11；
信道9的干扰信道包括:信道5—信道11；
信道10的干扰信道包括:信道6—信道11；
信道11的干扰信道包括:信道7—信道11。
需要说明的是，本申请实施例中涉及的信道数字(例如，信道1或信道2 等)，其中的数字代表信道索引。
需要说明的是，信道的带宽不一样，和/或信道个数不一样，会导致每个信道受到的干扰也可能不一样。
本申请实施例中涉及的任一信道对应的每个邻频干扰信道的信道距离系数是指该信道的安全信道距离与绝对值信道距离之间的差值，绝对值信道距离为该信道与该邻频干扰信道之间的信道距离的绝对值。
示例性地，可以通过公式d k＝c-|X 0-Y k|确定任一信道对应的第k个邻频干扰信道的信道距离系数；其中，d k代表该第k个邻频干扰信道的信道距离系数，c代表该任一信道的安全信道距离，X 0代表该任一信道的信道索引，Y k代表该第k个邻频干扰信道的信道索引。当然，还可以通过上述公式的其它变形或等效公式确定任一信道对应的第k个邻频干扰信道的信道距离系数，本申请实施例中对此并不作限制。
本申请实施例中涉及的信号强度信息可以包括但不限于：接收信号强度指示(Received Signal Strength Indication，RSSI)。
相关技术中，无人机从多个信道中随机选择一个目标信道，并通过目标信道与控制设备建立通信链路以进行信息传输。但相关技术中所选择的目标信道的干扰可能较大，会导致信息传输质量较差。
本申请实施例中提供的信息传输方法、装置及飞行器，通过根据至少2个信道分别对应的干扰量，从至少2个信道中选择出目标信道，所选择出的目标信道可以保证干扰量较小，以便通过目标信道进行信息传输，从而可以提高信息传输质量。
下面以具体地实施例对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。
图2为本申请一实施例提供的信息传输方法的流程示意图。如图2所示，本申请实施例的方法可以包括：
步骤S201、当符合预设扫描条件时，则进行信道扫描。
本步骤中，预设扫描条件包括但不限于以下任一项：当前处于通信连接的建立过程、当前通信信道的信号强度低于预设强度阈值、无人机与控制设备之间的距离低于预设距离。
示例性地，当无人机确定当前处于通信连接的建立过程时，则无人机进行信道扫描。例如，无人机可以在启动通信接口、或在启动内置的发送装置时， 确定无人机欲与控制设备建立通信链路，即确定当前处于通信连接的建立过程中。
或者，当无人机确定当前通信信道的信号强度低于预设强度阈值时，则无人机进行信道扫描，以便于后续从扫描到的至少2个信道中选择出合适的信道进行信息传输。例如，无人机在利用当前通信信道与控制设备建立有通信链路的情况下，无人机可以在与控制设备进行通信的过程中，实时或周期地监测当前通信信道的信号强度，当监测到信号强度低于预设强度阈值时，则进行信道扫描，以准备切换信道。进一步地，无人机还可以在监测到信号强度低于预设强度阈值时，进一步监测当前信号强度低于预设强度阈值的时长，若该时长大于或等于预设时长阈值，则进行信道扫描。
进一步地，预设扫描条件还可以是上述条件的结合。
例如，当无人机确定当前通信信道的信号强度低于预设强度阈值，且无人机与控制设备之间的距离低于预设距离时，则无人机进行信道扫描，以便于后续从扫描到的至少2个信道中选择出合适的信道进行信息传输。另外，通过在确定当前通信信道的信号强度低于预设强度阈值，且无人机与控制设备之间的距离低于预设距离时，无人机才开始进行信道扫描，可以防止在无人机与控制设备之间的距离大于预设距离(即各信道的信号强度可能都比较低)时还进行信道扫描，从而节省了无人机的电能资源。
需要说明的是，具体的信道扫描方式可以参考相关技术中的信道扫描方式，本申请实施例中对此并不作限制。
步骤S202、若扫描出至少2个信道，获取该至少2个信道分别对应的干扰量。
本步骤中，若在步骤S201中扫描出至少2个信道，则无人机分别获取该至少2个信道中每个信道对应的干扰量。可选地，无人机通过根据每个信道的干扰系数、安全信道距离以及对应的干扰信道等，分别确定每个信道对应的干扰量。
可选地，针对每个信道，获取该信道对应的同频干扰量和/或邻频干扰量；进一步的，根据该信道对应的同频干扰量和/或邻频干扰量，确定该信道对应的干扰量。
示例性地，假设任一信道具有同频干扰信道，且不具有邻频干扰信道，则无人机可以获取该信道对应的同频干扰量，并确定该信道对应的干扰量为该对应的同频干扰量。
又一示例性地，假设任一信道不具有同频干扰信道，且具有邻频干扰信道，则无人机可以获取该信道对应的邻频干扰量，并确定该信道对应的干扰量为该对应的邻频干扰量。
又一示例性地，假设任一信道具有同频干扰信道和邻频干扰信道，则无人机可以获取该信道对应的同频干扰量和邻频干扰量，并确定该信道对应的干扰量为该信道对应的同频干扰量与邻频干扰量之和。
本申请下述实施例对获取任一信道对应的同频干扰量的一种可实现方式进行描述：
根据同频干扰系数、安全信道距离以及该信道对应的至少一个同频干扰信道的信号强度信息，确定该信道对应的同频干扰量。
本申请实施例中，示例性地，无人机可以根据
