当控制终端接收到当前画面之后,会在显示界面上第一跟踪目标的位置 处显示一个标志,例如圆点和方框,以向用户标示第一跟踪目标当前所在的位置。
可选的,当第一跟踪目标的显示位置与上述第一预设位置的距离大于预设值时,控制终端会重新在第一预设位置显示上述第一跟踪目标。
本实施例中,控制终端根据用户所输入的启动跟踪指示即可控制无人机进行目标跟踪,并在获取到被跟踪目标的画面后,在显示画面中清楚地标示出该跟踪目标,从而使得用户的操作便捷,并且无需用户执行其他操作即可快速清楚地查看跟踪目标,从而极大地提升了用户的体验。进一步地,本实施例使用热跟踪的方式进行目标跟踪,可以保证无人机在不同的飞行状态下都可以快速准确地进行目标跟踪。
以下对本发明实施例的界面交互过程以及交互过程中的处理方法进行详细描述。
需要说明的是,以下各实施例中的显示界面中都会实时显示无人机当前所或捕获到的画面。
图3为本发明实施例提供的无人机的跟踪处理方法中用户对于第一控件的交互过程,如图3所示,界面交互过程为:
当用户初始登入跟踪界面之后,所显示的为画面(1),即在界面的左上方会显示第一控件,当用户点击第一控件之后,跟踪功能启动,画面会变为画面(2),即在界面的左边缘中间位置显示第二控件,并且第二控件的图标为第一图标,具体为暂停图标。用户如果点击第二控件,则会触发具体的目标跟踪,用户点击第二控件后的交互过程将在下述实施例中说明。本实施例中,在画面(2)中,控制终端会在显示界面上标示出最高温点并自动进行跟踪,即在当前所捕获的画面中的最高温点上进行标示并自动进行跟踪。进一步的,在图2的画面(3)中,再次执行点击第一控件的操作,跟踪功能关闭,此时画面会变为画面(4),在画面(4)中,仅显示第一控件,而不再显示第二控件。
需要说明的是,画面(3)所对应的操作,即用户在启动跟踪功能之后再次点击第一控件的操作,可以发生在启动跟踪功能之后的任何时刻,即用户可以在启动跟踪功能后的任何时刻通过再次点击第一控件来关闭跟踪功能。
上述界面交互过程中控制终端的处理过程为:
第一控件具有两种状态,分别为启动状态和停止状态。初始时第一控件为停止状态,当用户在上述画面(1)中点击第一控件之后,跟踪功能启动,第一控件变为启动状态,当用户在画面(3)中再次点击第一控件之后,跟踪功能关闭,第一控件变为停止状态。只有在第一控件处于启动状态时,第二控件才能被显示,进而用户通过操作第二控件来进行具体的目标跟踪、跟踪目标切换等。而当第一控件处于停止状态时,跟踪功能关闭,控制终端不会显示第二控件,也不会在画面上标示最高温点,也不会进行目标跟踪。
具体的,如画面(1)中所示,控制终端在显示的第二预设位置显示第一控件,并且检测用户是否对第一控件进行触控操作,如果检测到用户对第一控件的触碰操作,并且第一控件的状态为停止状态,则控制终端接收到了用户的启动跟踪指示。进而,控制终端将第一控件的状态调整为启动状态。进而,如画面(2)中所示,控制终端在显示界面的第三预设位置显示第二控件。进而,如画面(3)中所示,控制终端检测用户是否对第一控件进行触控操作,如果检测到用户对第一控件的触控操作,并且第一控件的状态启动状态,则停止跟踪,隐藏第二控件,并且将第一控件的状态调整为停止状态。
本实施例中,通过一个第一控件可以实现跟踪功能的启动和关闭,并且在第一控件为启动状态时再通过第一个第二控件来供用户进行具体的跟踪控制操作,从而使得操作简单,功能划分清晰,交互方式友好。
图4为本发明实施例提供的无人机的跟踪处理方法中用户使用第二控件开始目标跟踪和停止目标跟踪的交互过程,如图4所示,界面交互过程为:
当用户点击第一控件启动跟踪功能之后,在画面(1)中,会显示第二控件,此时第二控件的图标为第一图标,即暂停图标。此时控制终端会在画面(1)中对最高温点进行标示,并且将该最高温点作为跟踪目标自动进行跟踪。进一步的,在画面(2)中,用户再次执行点击第二控件的操作,此时画面变为画面(3),第二控件的图标从第一图标变为第二图标,即从暂停图标变为开始图标,同时停止对最高温点的跟踪,仅对最高温点进行标示。如果用户在画面(3)中再次点击第二控件,则画面又会变为画面(1)继续进行交互过程。
上述界面交互过程中控制终端的处理过程为:
第二控件具有两种状态,分别为跟踪状态和暂停状态,在不同的状态下 第二控件的显示图标不同。具体的,在跟踪状态下显示暂停图标,在暂停状态下显示开始图标。初始时第二控件为暂停状态,当进入画面(1)时,第二控件自动变为跟踪状态,第二控件的图标变为跟踪状态。当进入画面(3)时,第二控件自动变为暂停状态,第二控件的图标变为开始图标。
具体的,当检测到用户对第二控件的触碰操作,并且第二控件的状态为暂停状态,则控制终端跟踪第一跟踪目标,将第二控件的状态调整为跟踪状态,将第二控件的显示图标调整为第一图标。
当检测到用户对第二控件的触碰操作,并且第二控件的状态为跟踪状态,则停止跟踪,将第二控件的状态调整为暂停状态,将第二控件的显示图标调整为第二图标。
除了通过检测触碰操作来将第二控件的状态调整为暂停状态为,以下场景下也可以将第二控件的状态调整为暂停状态:
如果在预设时段内未搜索到跟踪目标,并且第二控件的状态为跟踪状态,则停止跟踪,将第二控件的状态调整为暂停状态,将第二控件的显示图标调整为第二图标。
本实施例中,通过对同一个第二控件在不同状态下设置不同的图标,使得用户通过统一个图标来进行具体的跟踪控制,从而使得操作简单,交互方式友好。
图5为本发明实施例提供的无人机的跟踪处理方法的流程示意图,如图5所示,上述方法还包括:
S501、通过热跟踪确定第二跟踪目标,该第二跟踪目标的温度高于上述第一跟踪目标的温度。
S501、在显示界面上显示预设的标志,该预设的标志用于标示上述第二跟踪目标。
具体的,当显示界面如图4中画面(1)所示进行目标跟踪的过程中,无人机会持续检测被跟踪的第一跟踪目标及其周围的温度,当检测到周围某个点的温度比第一跟踪目标的温度高,即为当前最高温时,将其作为第二跟踪目标,并在显示界面中该第二跟踪目标上加上预设的标志。
图6为跟踪目标切换的界面示例图,本实施例的界面示例如图6中画面(1)所示,如图(6)中画面1所示,当前正在跟踪的为第一跟踪目标,画 面(1)中对其进行标示。当无人机检测到第二跟踪目标的温度为当前最高时,在界面中对第二跟踪目标进行标示。需要说明的是,第二跟踪的标示方式需要与第一跟踪目标加以区分,以便于用户方便地查看。示例性的,在本发明实施例中,在当前正在被跟踪的目标周围加上框线,而在第二跟踪目标上使用虚线加圆圈的方式来标示。
进一步的,当画面中出现第二跟踪目标的标示后,用户可以选择切换到第二跟踪目标进行跟踪。
在一种可选的实施方式中,用户可以通过连续点击第二控件方式来切换跟踪目标。具体的,每当第二控件从暂停状态变为跟踪状态后,控制终端都会控制无人机重新选择当前温度最高的点进行跟踪。因此,如果当前正在跟踪第一跟踪目标而第二跟踪目标的温度比第一跟踪目标高,则用户可以先点击一次第二控件,点击之后第二控件处于暂停状态,无人机不跟踪任何目标。进而,用户再点击一次第二控件,点击之后第二控件进入跟踪状态,此时无人机会选择当前温度最高的点进行跟踪,由于此时第二跟踪目标的温度最高,因此无人机会跟踪第二跟踪目标,即实现了从第一跟踪目标到第二跟踪目标的切换。每次点击之后的具体处理过程可以参照前述第二控件的交互过程,此处不再赘述。
在另一种可选的实施方式中,用户也可以通过点击第二跟踪目标的标示的方法来切换跟踪目标。
图7为本发明实施例提供的无人机的跟踪处理方法的流程示意图,如图7所示,在显示界面中标示出第二跟踪目标后,还包括:
S701、接收用户输入的切换跟踪目标指示。
具体的,控制终端会判断用户是否对显示界面中上述预设的标志所在位置执行触碰操作,若是,则接收上述切换跟踪目标指示。
界面示例如图6中画面(2)所示,在画面(2)中,用户点击第二跟踪目标对应的标示,则控制终端即接收到切换跟踪目标指示。
S702、根据上述切换跟踪目标指示,跟踪第二跟踪目标,并停止跟踪第一跟踪目标。
S703、在上述第一预设位置标示被跟踪的第二跟踪目标。
具体的,控制终端根据切换跟踪目标指示,会指示无人机停止跟踪第一 跟踪目标,而改为跟踪第二跟踪目标。并且在切换跟踪目标之后,调整画面角度,以将当前被跟踪的第二跟踪目标显示在第一预设位置,并在第一预设位置上标示第二跟踪目标,从而保证被跟踪的目标一直处于画面中的同一位置。
界面示例如图6中画面(3)所示,停止跟踪第一跟踪目标之后,不再在画面上标示第一跟踪目标,而是按照第一跟踪目标被跟踪时的标示方式来标示第二跟踪目标,并且将跟踪目标显示在画面的中心位置。
