具体实施方式
下面将结合本说明书实施例中的附图,对本说明书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说明书一部分实施例,而不是全部的实施例。基于本说明书中的实施例,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,都属于本说明书保护的范围。
附图中所示的流程图仅是示例说明,不是必须包括所有的内容和操作/步骤,也不是必须按所描述的顺序执行。例如,有的操作/步骤还可以分解、组合或部分合并,因此实际执行的顺序有可能根据实际情况改变。
屏上显示模块11(On Screen Display,OSD)与飞控模块12以及无人机10搭载的摄像装置13连接如图1所示。这个硬件模块将飞行过程中的状态和 无人机所拍摄图像进行叠加处理后传输给显示设备进行显示和记录。例如采用liveview的方式。但是叠加处理这种方式需要将OSD数据与图像叠加和关联,需要额外增加硬件,导致功耗变大,引入较大的处理时延,这会导致无人机的整体时延变大。功耗变大会导致无人机的整体续航时间变短,图像处理过程还容易导致无人机的局部发热大;对于依赖图传数据进行无人机操控的情况,图传时延的危害可能会导致危害结果,严重的甚至会导致无人机炸机。

在一些实施方式中,所述可移动平台将所述屏上显示信息通过图传信道发送给用户端,以使所述用户端根据所述显示时间对所述状态数据进行显示,包括:将预设格式的所述屏上显示信息通过图传信道发送给用户端,以使所述用户端接收所述屏上显示信息和解析所述屏上显示信息得到所述状态数据和所述显示时间,并使所述用户端根据所述显示时间对所述状态数据进行显示。

在一些实施方式中,用户端存储所述来自可移动平台的图像信息以生成视 频文件。例如,用户端根据接收到的来自可移动平台的图像信息生成视频文件。具体的,根据接收图像信息的先后顺序将多个图像信息进行存储得到视频文件。以便后续可以重放视频文件,如便于裁判判罚,或者操作者可以根据OSD信息对操作进行复盘。
示例性的,如图4所示,步骤S130将所述图像信息和所述屏上显示信息通过图传信道发送给用户端,包括步骤S132。
S132、将所述图像信息和所述屏上显示信息通过图传信道发送给用户端,以使所述用户端基于所述图像信息的时间轴,根据所述屏上显示信息生成与所述图像信息同步的屏上显示信息文件。
示例性的,用户端根据图像信息的时间轴生成屏上显示信息文件。例如,根据视频文件中各图像信息时间轴与屏上显示信息显示时间的对应关系,对接收到的多条屏上显示信息进行排序存储,得到与视频文件同步的屏上显示信息文件。
示例性的,用户端还可以根据屏上显示信息的显示时间,将多个屏上显示信息进行存储得到与视频文件对应的屏上显示信息文件。使得在重放视频文件时,用户端依然可以调出屏上显示信息文件,在显示的图像信息时同步显示屏上显示信息,以还原图像信息拍摄时可移动平台的状态和/或用户端的状态。
在一些实施方式中,所述数据发送方法还包括:从所述用户端获取用户对所述用户端的操作事件,根据所述操作事件和与所述操作事件关联的屏上显示信息和/或图像信息生成埋点数据;在连接至终端设备时,将所述埋点数据发送给所述终端设备。
具体的,用户操作用户端,使得用户端产生对可移动平台的控制指令,用户端通过上行信道将控制指令发送给可移动平台。可移动平台根据控制指令实现相应的控制操作,还实时向用户端发送图像信息和屏上显示信息。
具体的,用户操作用户端,使得用户端向可移动平台发送控制指令;同时控制指令触发可移动平台的埋点事件,可移动平台会产生埋点数据。
具体的,可移动平台根据所述控制指令的生成时间或接收时间、以及图像信息的时间轴、屏上显示信息的显示时间,确定与所述操作事件关联的屏上显示信息和/或图像信息;之后根据所述操作事件和与所述操作事件关联的屏上显示信息和/或图像信息生成埋点数据。示例性的,由于埋点数据的数据量比较庞 大,需要格式转换、封装压缩处理,达到节省空间的效果。同时记录每个埋点数据的时间戳,如将控制指令的生成时间作为相应埋点数据的时间戳,然后可移动平台将处理后的埋点数据生成埋点文件。
在一些实施方式中,所述数据发送方法还包括:若接收到所述终端设备发送的上传成功通知,将所述上传成功通知对应的埋点数据删除。
示例性的,可移动平台检测到连接至手机、电脑等终端设备时,会触发获取存储的埋点文件,如JSON文件。由于埋点文件是经过封装压缩的,需要按规则解压才能还原成真实的埋点数据,包括事件的触发时间;之后可移动平台将埋点数据上传给连接的终端设备。
从而可以实现在可移动平台,如无人机本地实现埋点功能;可以在可移动平台升级等场景下需要连接手机、电脑的时候,用户无感地将埋点数据上传到手机、电脑等终端设备;还可以由可联网的终端设备将埋点数据上传至服务器;因此对于无人机不连接移动设备的情况下,也可以进行埋点统计。
上述实施例提供的用于可移动平台的数据发送方法,通过获取可移动平台搭载摄像装置拍摄的图像信息,并基于可移动平台的状态数据,生成与图像信息时间同步的屏上显示信息;然后将图像信息和屏上显示信息通过图传信道发送给用户端,以使用户端显示图像信息,以及在显示图像信息时同步显示屏上显示信息。图像信息和可移动平台的状态数据分别进行传输,避免屏上显示模块的图像处理过程引起的时延增加、功耗增加和发热增加,且不需要额外增设硬件。

在一些实施方式中,用户端如FPV眼镜可以在本地进行数据埋点统计、存储、上传。
数据埋点功能一般用于统计、收集用户的使用习惯、行为操作等信息,然后把收集到的数据通过网络媒介上传到数据服务器,进行分析,了解用户需求,改进、优化产品功能。传统上,数据埋点功能一般运用于有网络模块的设备,如手机、电脑等,可以做到实时传输;对于一些本身无网络模块的设备,如消费机无人机,也没有在飞机本地实现埋点功能,而是连接手机等移动设备,由移动设备代理负责埋点数据的收集、统计、传输。
但是目前有一些用户端,如无网络模块的FPV眼镜、穿越机眼镜,是没有实现埋点统计、存储、上传的功能的,所以无法收集到用户使用眼镜设备的习惯、行为等信息。
对于本身无网络模块的用户端电子设备,而且长期不需要连接如手机、电脑等具有网络模块的设备,典型的例子就是穿越机FPV眼镜,此类设备一般具有独立的用户交互,如UI界面、按键触控板等,完全不需要手机等移动设备的介入,如果希望能收集、统计用户的使用习惯等信息,那么就需要在设备本地进行数据的收集、统计、存储。
在本实施例中,在用户端未连接手机等移动设备或PC电脑时,用户端将埋点数据通过软件方式封装、压缩存储成埋点文件,且每一个埋点数据都包含时间信息,并将埋点文件保存在用户端,如FPV眼镜本地。当用户端连接至手机、PC电脑等终端设备进行系统升级、调试等操作时,用户端会触发解析埋点文件、将解析得到的埋点数据上传至终端设备。由于每个埋点数据都包含了时间信息,所以这种埋点数据的传输方式和实时传输无差别,在数据服务器上仍然可以基于时间轴对埋点数据进行分类、统计。
对于本身无网络模块的用户端电子设备,而且长期不需要连接如手机、电 脑等具有网络模块的设备,用户一般只会在设备需要升级的时候才会尝试将用户端连接至手机、电脑等终端设备;这个时候,就可以把存储在用户端本地的埋点数据通过手机、电脑等代理上传到服务器上,而用户也无感知,不影响其正常使用。
示例性的,用于用户端的数据处理方法还包括:获取用户操作所述用户端的操作事件,根据所述操作事件和与所述操作事件关联的屏上显示信息和/或图像信息生成埋点数据。
具体的,用户操作用户端,使得用户端产生对可移动平台的控制指令,用户端通过上行信道将控制指令发送给可移动平台。可移动平台根据控制指令实现相应的控制操作,还实时向用户端发送图像信息和屏上显示信息。
具体的,用户操作用户端,使得用户端产生向可移动平台发送的控制指令;同时触发埋点事件,会产生埋点数据。
具体的,用户端根据所述控制指令的生成时间、图像信息的时间轴、屏上显示信息的显示时间,确定与所述操作事件关联的屏上显示信息和/或图像信息;之后根据所述操作事件和与所述操作事件关联的屏上显示信息和/或图像信息生成埋点数据。
示例性的,由于埋点数据的数据量比较庞大,需要格式转换、封装压缩处理,达到节省空间的效果。同时记录每个埋点数据的时间戳,如将控制指令的生成时间作为相应埋点数据的时间戳,然后用户端将处理后的埋点数据生成埋点文件。
示例性的埋点文件可以是二进制DAT文件、ini文件、又或者是文本TXT文件等;埋点文件可以保存到掉电不丢失存储介质,例如SD卡,NAND FLASH等。
示例性的,用户端将处理后的埋点数据生成JSON文件,保存到内部EMMC(Embedded Multi Media Card)模块中,确保掉电不丢失数据。
在一些实施例中,用于用户端的数据处理方法还包括:在用户端连接至终端设备时,将所述埋点数据发送给所述终端设备。
示例性的,用户端检测到连接至手机、电脑等终端设备时,会触发获取存储的埋点文件,如JSON文件。由于埋点文件是经过封装压缩的,需要按规则解压才能还原成真实的埋点数据,包括事件的触发时间;之后用户端将埋点数据 上传给连接的终端设备。
对于本身无网络模块的用户端电子设备,如FPV眼镜、穿越机眼镜尽管没有网络模块,但是设备进行系统升级、调试时,仍需要连接手机或PC电脑等终端设备,这就给用户端本地存储的埋点数据提供上传的机会。
由于用户对设备进行升级的操作,不是高频行为,这就要求用户端本地存储的埋点数据必须是高压缩的,以实现有限的空间存储更多的埋点数据,一般要求做到存储半年以上的数据。
示例性的,在用户端连接至可联网的终端设备时,将所述埋点数据发送给所述终端设备,以使所述终端设备将所述埋点数据上传至服务器。
用户端将埋点数据上传给连接的终端设备之后,终端设备可以将埋点数据进一步上传至服务器,以便服务器对埋点数据进行分类、统计,获取用户的使用习惯、真实需求等,有利于产品更新迭代、优化改进。
在一些实施例中,用于用户端的数据处理方法还包括:若接收到所述终端设备发送的上传成功通知,将所述上传成功通知对应的埋点数据和/或埋点文件删除。
具体的,当与用户端通信连接的终端设备接收到完整的埋点数据之后,向用户端反馈上传成功通知;用户端根据上传成功通知后可以将本地存储的埋点数据和/或埋点文件删除,以释放更多的空间记录新的埋点数据。
