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,都属于本发明保护的范围。
除非另有定义,本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的,不是旨在于限制本发明。
为了便于理解本申请的技术方案,下面对现有技术进行简要说明:
现有技术中的拍摄技术,在光照复杂的情况下(比如:逆光),通常可以通过人手打反光板、补光灯、闪光灯等进行主动干预,例如:在利用手机进行自拍时,夜晚中会自动启动闪光灯进行补光操作;或者,可以通过调节预设的目标与光线的补光曲线参数进行补光操作。
然而,上述的通过人手打反光板的方式进行补光的方式,需要多人配合操作,在单人拍摄的时候难以满足要求;而通过开启闪光灯对目标象进行补光的方式,可以实现短暂地为目标进行补光,然而,控制开启闪光灯的逻辑比较简单,仅仅会针对环境光线的情况判断一次,因此,这种方式仅仅适用于拍照的应用场景,适用范围较小;在通过调节预设的补光曲线参数为目标进行补光时,虽然实现了对目标进行补光的操作,但是,无法保证为目标进 行补光的效果,容易使得目标出现过渡曝光的问题。
下面结合附图,对本发明的一些实施方式作详细说明。在各实施例之间不冲突的情况下,下述的实施例及实施例中的特征可以相互组合。
图1为本发明实施例提供的一种补光控制方法的流程示意图;参考附图1所示,为了解决现有技术中存在的上述问题,本实施例提供了一种补光控制方法,该方法可以应用于云台,该云台上设置有拍摄装置,该拍摄装置可以为照相机、摄像机或者其他具有拍摄功能的任意设备。另外,该方法的执行主体可以为补光控制装置,可以理解的是,该补光控制装置可以实现为软件、或者软件和硬件的组合。具体的,该方法可以包括:
S1:在跟踪目标对象的过程中,获取目标对象所在区域的图像信息。
其中,在通过云台上的拍摄装置跟随目标对象的过程中,由于目标对象的运动范围较大,光照情况很可能会复杂多变,比如:由亮处走到阴影处、或者由顺光走到逆光处,此时,为了提升对目标对象进行拍摄或者跟踪的效果,则可以根据目标对象在图像信息中的亮度信息,判断是否需要为目标对象进行补光操作。具体的,可以先利用拍摄装置获取目标对象所在区域的图像信息,该图像信息中可以包括目标对象以及目标对象所在的周围环境信息,通过对图像信息进行分析识别,可以获取到目标对象的亮度信息,以便根据目标对象的亮度信息判断是否对目标对象进行补光操作。
S2:确定目标对象在图像信息中的亮度信息。
在获取到图像信息之后,可以对图像信息进行分析处理,从而可以确定目标对象在图像信息中的亮度信息,该亮度信息可以包括YUV信息,具体的,YUV信息中的“Y”表示明亮度,也就是灰阶值;而“U”和“V”表示的则是影像色彩及饱和度,用于指定像素的颜色。另外,本实施例对于确定目标对象在图像信息中的亮度信息的具体实现方式不做限定,本领域技术人员可以采用现有技术来获取亮度信息,例如:可以先将图像信息转换为数组信息,通过对数组信息的分析识别可以确定目标对象的亮度信息等等,在此不再赘述。
S3:在亮度信息小于预设阈值时,则对目标对象进行补光操作。
其中,预设阈值为预先设置的用于判断目标对象的亮度信息是否满足预设条件的亮度限值,该亮度限值可以是一个数值或者是一个数值区间,本实施例对于预设阈值的大小不做限定,本领域技术人员可以根据具体的应用场 景和应用需求进行任意设置,在此不再赘述。在亮度信息小于预设阈值时,则说明目标对象的亮度信息较暗,此时无法保证目标对象在图像信息中的显示效果,此时,为了保证目标对象在图像信息中显示的清晰度,可以自动地对目标对象进行补光操作,从而有效地保证了目标对象在图像信息中的显示效果。
需要注意的是,本实施例中的补光控制方法不仅可以应用在跟踪目标对象的过程中,还可以应用在对目标对象进行拍摄的过程中,此时,本实施例中的方法可以适应性调整为:在利用云台上的拍摄装置对目标对象进行拍摄的过程中,获取目标对象所在区域的图像信息,确定目标对象在图像信息中的亮度信息,在亮度信息小于预设阈值时,则对目标对象进行补光操作,这样不仅有效地保证了对目标对象进行拍摄的效果,还提高了该方法的适用范围。
本实施例提供的补光控制方法,在跟踪目标对象的过程中,或者,在对目标对象进行拍摄的过程中,通过确定目标对象在图像信息中的亮度信息,并且在亮度信息不足的情况下,可以对目标对象进行补光操作,有效地保证了目标对象在图像信息中的显示效果,提高了对目标对象进行跟踪或者拍摄的稳定可靠性,进一步保证了该方法的实用性,有利于市场的推广与应用。
在上述实施例的基础上,继续参考附图1所示,本实施例对于对目标对象进补光操作的具体实现方式不做限定,本领域技术人员可以根据具体的应用需求和设置需求进行设置,其中,一种可实现对目标对象进行补光操作的方式包括:
S31:通过开启预设的补光设备对目标对象进行补光操作。
其中,预设的补光设备可以包括以下至少之一:设置于拍摄装置上的闪光灯、设置于云台上的补光灯、独立于拍摄装置和云台的补光灯。具体的,在需要对目标对象进行补光操作时,可以控制设置于拍摄装置上的闪光灯、设置于云台上的补光灯或者独立于拍摄装置和云台的补光灯长亮或者按照预设的工作频率进行工作等等,只要能够实现对目标对象进行补光操作,保证目标对象在图像信息中的显示效果即可。
在一种实施例中,参考附图2所示,在预设的补光设备包括设置于拍摄装置上的闪光灯时,本实施例中的通过开启预设的补光设备对目标对象进行补光操作可以包括:
S311:获取对目标对象进行跟踪的视频信息。
S312:通过闪光灯确定与视频信息中部分视频帧相对应的补光参数。
S313:利用补光参数对视频信息中的目标对象进行补光操作。
具体的,在对目标对象进行跟踪拍摄时,可以通过拍摄装置获取与目标对象相对应的视频信息,该视频信息中可以包括若干个视频帧;当视频信息中的目标对象需要进行补光操作时,可以利用设置于拍摄装置的闪光灯进行补光操作时,具体的,可以控制闪光灯长亮或者以预设频率进行闪亮来进行补光操作,其中,在控制闪光灯以预设频率进行闪亮时,由于闪光灯的工作特性,可以获得与视频信息中的部分视频帧相对应的补光参数,该补光参数可以包括感光度和快门速度等等。在获取到与部分视频帧相对应的补光参数之后,为了保证目标对象在整个视频信息中的显示效果,则可以利用该补光参数对整个视频信息中的所有视频帧进行补光操作,从而实现了基于与部分视频帧所对应的补光参数对整个视频信息中的目标对象进行补光的操作,保证了目标对象在视频信息中显示的清晰度,进一步提高了对目标对象进行跟踪的稳定可靠性。
图3为本发明实施例提供的对目标对象进行补光操作的流程示意图一;在上述实施例的基础上,继续参考附图3所示,本实施例中提供了另一种可实现对目标对象进行补光操作的方式,具体的,包括:
S32:获取与显示区域相对应的补光显示画面,显示区域用于显示图像信息。
其中,补光显示画面可以预先设置或者预先存储的显示画面,该补光显示画面用于提高目标对象所在环境的亮度信息。具体的,该补光显示画面可以存储在预设区域或者预设装置中,通过访问预设区域或者预设装置可以获取到与显示区域相对应的补光显示画面。具体应用时,补光显示画面可以包括以下至少之一:预设颜色的纯色画面、预设颜色的图形画面;其中,预设颜色为亮度大于或等于预设亮度阈值的颜色,此处的预设亮度阈值可以是预先设置的亮度限制,当颜色的亮度大于或等于预设亮度阈值时,则说明该颜色为满足条件的预设颜色;当颜色的亮度小于预设亮度阈值时,则说明该颜色为不满足条件的颜色。另外,本实施例对于预设亮度阈值的数值范围不做限定,本领域技术人员可以根据具体的应用需求和设计需求进行设置,例如:假设白色的亮度信息为100%,黑色的亮度信息为0,那么,预设亮度阈 值可以为80%、85%、90%或者95%等等,只要能够达到通过补光显示画面的亮度信息为目标对象进行补光的效果即可,在此不再赘述。
另外,本实施例对于预设颜色的图形画面的具体图形形状不做限定,本领域技术人员可以根据具体的应用需求和设计需求进行设置,例如:可以将预设颜色的图形画面设置为预设颜色的环形画面,此时,在目标对象为人物头像时,通过所显示的预设颜色的环形画面,例如:在针对目标对象进行近距离补光、且目标对象为人物时,为了保证目标对象的显示效果,可以控制显示区域中显示纯白色的环形画面,如图4所示,从而实现了对目标对象的补光更加柔和,并且会在人物的眼眸中呈现出明亮的反射,显得眼睛更有神,有效地提升了人物的拍摄效果。或者,可以将预设颜色的图形画面设置为预设颜色的方形画面,此时,在目标对象为移动的物体时,可以实现对目标对象进行稳定、有效地补光操作。当然的,本领域技术人员也可以将图形画面设置为其他的形状结构,只要能够实现为目标对象进行补光、保证目标对象在图像信息中的显示效果即可,在此不再赘述。
S33:将补光显示画面在显示区域中进行显示,以实现对目标对象进行补光操作。
在获取补光显示画面之后,可以将补光显示画面在显示区域内进行显示,操作简单、方便,并且有效地实现了对目标对象进行补光的操作,保证了目标对象的显示效果。
另外,在显示区域显示补光显示画面时,显示区域中还可以显示或者不显示对目标对象进行跟踪或者拍摄的画面。举例来说:用户通过手机的前置摄像头进行拍摄或者跟踪目标对象时,在目标对象的亮度较暗时,可以通过手机的显示屏幕显示补光显示画面来对目标对象进行补光操作,此时,手机的显示屏幕中可以显示对目标对象进行跟踪或者拍摄的画面,例如:对目标对象进行跟踪或者拍摄的画面可以以缩小的预览画面方式在显示屏幕中的一个角落进行显示,例如:在显示屏幕中的左上角显示预览画面,或者,在显示屏幕中的右上角显示预览画面等等。或者,手机的显示屏幕中可以不显示对目标对象进行拍摄的画面,在对目标对象进行拍摄完毕之后,手机的显示屏幕可以将所显示的补光显示画面调整为对目标对象进行拍摄的画面,从而使得用户可以获取到对目标对象进行拍摄的效果。
图5为本发明实施例提供的另一种补光控制方法的流程示意图的流程示 意图;在上述实施例的基础上,继续参考附图5所示,在将补光显示画面在显示区域中进行显示时,本实施例中的方法还可以包括:
S101:在显示区域中确定预览区域。
S102:通过预览区域对目标对象进行预览显示。
具体的,在跟踪目标对象的过程中,可以利用拍摄装置的后置摄像头或者前置摄像头对目标对象进行跟踪拍摄,当利用拍摄装置的前置摄像头对目标对象进行跟踪拍摄、且将补光显示画面在显示区域中进行显示时,为了使用户可以及时了解对目标对象进行跟踪拍摄的显示效果,可以在显示区域中设置一预览区域,该预览区域可以设置于显示区域的一个角落位置,例如,预览区域设置于显示区域的左上角、右上角、左下角或者右下角等等,在预览区域中可以对目标对象进行预览显示,从而使得用户可以直观地了解到目标对象的跟踪拍摄效果。
图6为本发明实施例提供的对目标对象进行补光操作的流程示意图二;在上述实施例的基础上,继续参考附图6所示,本实施例中提供了还一种可实现对目标对象进行补光操作的方式,具体的,包括:
S34:获取与目标对象相对应的拍摄参数。
S35:对拍摄参数进行调节,以实现对目标对象进行补光操作。
其中,在利用拍摄装置对目标对象进行跟踪拍摄时,可以获取到与目标对象相对应的拍摄参数,该拍摄参数可以包括用于衡量底片对于光的灵敏程度的感光度、快门速度等等。在获取到拍摄参数之后,可以对拍摄参数进行调整,从而实现对目标对象进行补光操作。具体的,在拍摄参数包括感光度时;对拍摄参数进行调节可以包括:
S351:提高与目标对象相对应的感光度。
其中,本实施例对于提高感光度的具体幅度不做限定,本领域技术人员可以根据具体的应用场景和应用需求对感光度进行调整,通过提高与目标对象相对应的感光度之后,可以调高底片对于光的灵敏程度,从而实现了对目标对象进行补光的操作。
或者,在拍摄参数包括快门速度时,本实施例中的对拍摄参数进行调节可以包括:
S352:增加与目标对象相对应的快门速度。
其中,本实施例对于提高快门速度的具体幅度不做限定,本领域技术人 员可以根据具体的应用场景和应用需求对快门速度进行调整,通过提高与目标对象相对应的快门速度之后,不仅可以保证目标对象在显示区域中的显示效果,并且还可以使得拍摄装置轻松捕捉快速移动的目标对象,从而保证了对目标对象进行跟踪的稳定可靠性。
图7为本发明实施例提供的对目标对象进行补光操作的流程示意图三;在上述实施例的基础上,继续参考附图7所示,本实施例中提供了另一种可实现对目标对象进行补光操作的方式,具体的,包括:
S301:根据目标对象的亮度信息,确定与目标对象相对应的补光角度。
S302:根据补光角度,通过云台对拍摄装置进行调整。
具体的,在获取到目标对象的亮度信息之后,可以根据目标对象的亮度信息确定与目标对象相对应的补光角度。在获取到补光角度之后,可以通过云台对拍摄装置进行调整,以实现基于补光角度对目标对象进行补光操作。具体的,参考附图8所示,本实施例中的根据补光角度,通过云台对拍摄装置进行调整可以包括:
S3021:获取目标对象的位置信息和拍摄装置的拍摄角度。
S3022:根据补光角度和目标对象的位置信息,确定拍摄装置的目标拍摄角度。
S3023:通过云台,将拍摄装置的拍摄角度调整为目标拍摄角度。
具体的,在利用拍摄装置对目标对象进行跟踪拍摄时,可以获取到目标对象的位置信息和拍摄装置的拍摄角度;在获取到补光角度之后,可以对补光角度和目标对象的位置信息进行分析处理,从而可以确定拍摄装置的目标拍摄角度。由于拍摄装置设置于云台上,因此,可以通过对云台的调整实现对拍摄装置的拍摄角度进行调整,从而可以将拍摄装置的拍摄角度调整为目标拍摄角度,实现了基于补光角度对目标对象进行补光的操作,进一步提高了对目标对象进行补光的质量和效率。
图9为本发明实施例提供的又一种补光控制方法的流程示意图的流程示意图;在上述任意一个实施例的基础上,继续参考附图9所示,为了提高该方法的实用性,本实施例中的方法还可以包括:
S401:在亮度信息大于或等于预设阈值时,则获取目标对象所在环境的环境亮度信息和拍摄光线信息。
S402:在环境亮度信息大于或等于预设阈值,且拍摄光线信息为非逆光 状态时,则停止对目标对象进行补光操作。或者,
S403:在环境亮度信息小于预设阈值,或者,拍摄光线信息为逆光状态时,则继续对目标对象进行补光操作。
具体的,在亮度信息进行分析处理的结果为亮度信息大于或等于预设阈值时,则说明目标对象在显示区域中的亮度信息满足预设的亮度要求,为了进一步保证对目标对象进行跟踪拍摄的效果,可以获取到目标对象所在环境的环境亮度信息和拍摄光线信息,其中,拍摄光线信息可以包括逆光信息和非逆光信息;进一步根据环境亮度信息和拍摄光线信息判断是否需要对目标对象进行补光操作。具体的,在获取到目标对象所在环境的环境亮度信息和拍摄光线信息时,可以通过对图像信息的分析识别,获取目标对象所在环境的环境亮度信息和拍摄光线信息。
在获取到环境亮度信息和拍摄光线信息之后,可以对环境亮度信息和拍摄光线信息进行分析处理,具体的,将环境亮度信息与预设阈值进行比较、同时判断拍摄光线信息是否为逆光信息,在环境亮度信息大于或等于预设阈值、且拍摄光线信息为非逆光状态时,则说明此时的目标对象的光线信息以及所处环境的光线信息满足预设的跟踪拍摄要求,进而可以停止对目标对象进行补光操作;具体的,在需要停止对目标对象进行补光操作时,可以包括:关闭预设的补光设备;或者,停止在显示区域中显示补光显示画面。在环境亮度信息小于预设阈值,或者,拍摄光线信息为逆光信息时,则说明此时的目标对象所在环境的光线信息不满足预设的跟踪拍摄要求,因此为了保证目标对象的跟踪拍摄效果,则可以继续对目标对象进行补光操作。
通过环境亮度信息和拍摄光线信息判断何时停止对目标对象进行补光操作,有效地实现了在目标对象需要进行补光操作时,可以持续地对目标对象进行补光操作,在目标对象不需要进行补光操作时,可以及时停止为目标对象进行补光操作,从而不仅保证了目标对象的显示效果,并且有效地避免了电力资源、数据资源的浪费,进一步提高了该方法使用的灵活可靠性。
在上述任意一个实施例的基础上,在跟踪目标对象的过程中,本实施例中的方法还可以包括:
S501:控制目标对象位于拍摄装置的视场范围内。
其中,在对跟踪目标对象的过程中,为了保证跟踪拍摄的稳定可靠性,可以控制目标对象位于拍摄装置对视场范围内,也即,在跟踪目标对象的过 程中,可以使得目标对象尽量位于图像信息的中央位置处,从而避免了对目标对象进行丢失的情况,进一步提高了该方法使用的稳定可靠性。
具体应用时,参考附图10所示,本应用实施例提供了一种补光控制方法,包括:
step1:确定待跟踪的目标对象,对目标对象进行跟踪。
在显示区域中,显示有目标对象以及目标对象所在的环境信息,其中,目标对象的个数可以为一个或多个,在确定待跟踪的目标对象之后,可以利用标记框将目标对象进行标定显示,从而便于用户获知清楚地获知到目标对象在显示区域中的显示位置。
step2:在跟踪目标对象的过程中,获取目标对象所在区域的图像信息,确定目标对象在图像信息中的亮度信息。
在确定待跟踪的目标对象之后,可以对图像信息进行分析识别,统计目标对象标记框中的亮度信息,从而可以获取到目标对象在图像信息中的亮度信息。
step3:根据亮度信息判断目标对象是否过暗。
在获取到亮度信息之后,可以将亮度信息与预设的亮度阈值进行比较,若亮度信息小于亮度阈值,则可以确定目标对象过暗,若亮度信息大于或等于亮度阈值,则可以确定目标对象的亮度信息满足预设需求。
step4:在目标对象过暗时,则可以对目标对象进行补光操作。
具体的,对目标对象进行补光操作可以包括以下至少之一:
(1)提升拍摄装置的感光度或者增加快门时长。该方式虽然可以增加目标对象的亮度,然而,这种方式在逆光的场景下,容易让图像信息中的背景信息过曝,从而影响整个图像信息的显示效果,因此,该方法可以适用于非逆光的应用场景下。
(2)持续通过开启预设的补光设备对目标对象进行补光操作,预设的补光设备可以包括以下至少之一:设置于拍摄装置上的闪光灯、设置于云台上的补光灯、设置于云台背面的闪光灯、独立于拍摄装置和云台的补光灯。这种补光方式在低光照的情况下,可以实现提升目标对象的亮度更有效,并且,在逆光的情况下,也可以减少背景过曝的情况。
(3)控制显示区域显示预先设置的补光显示画面,该补光显示画面包括以下至少之一:预设颜色的纯色画面、预设颜色的图形画面;其中,预设颜 色为亮度大于或等于预设亮度阈值的颜色。
(4)获取目标对象的位置信息和拍摄装置的拍摄角度,通过云台调整拍摄装置的拍摄角度,以实现为目标对象进行补光的效果。
由于拍摄装置设置于云台上,而通过拍摄装置上的闪光灯或者补光灯进行补光操作时,拍摄装置的补光角度会对目标对象的补光效果产生影响,因为,为了保证目标对象的补光效果,可以对拍摄装置的补光角度进行调整,具体的,可以通过对云台的调整实现对拍摄装置的补光角度进行调整,从而实现了对目标对象进行补光的效果。
step5:在对目标对象进行补光操作之后,可以保证目标对象的显示效果,此时,目标对象的亮度信息可以满足预设需求,在确定目标对象的亮度信息满足预设需求之后,则可以继续判断环境亮度是否足够亮并且非逆光。
step6:在环境足够亮并且非逆光时,则可以停止对目标对象进行补光操作;在环境没有足够亮或者逆光时,则可以继续对目标对象进行补光操作。
其中,停止对目标对象进行补光操作时,可以关闭设置于拍摄装置上的闪光灯、设置于云台上的补光灯、独立于拍摄装置和云台的补光灯,或者,也可以关闭所显示的补光显示画面,以实现停止对目标对象进行补光操作。
step7:在停止对目标对象进行补光操作之后,可以继续对跟踪目标对象的视频信息中的下一帧数据进行补光判断。
本实施例提供的补光控制方法,通过目标跟随技术可以持续地跟踪目标对象,在对目标对象进行跟随的过程中,可以基于目标对象的显示效果动态地改变目标对象的补光策略,去除环境对补光策略的影响,实现了更灵活的补光操作;有效地解决了在光线复杂的场景中,无法根据目标对象当前的光照情况快速地进行动态改变光照,导致画面内容效果无法达到预期的问题,不仅保证了目标对象在图像信息中的显示效果,并且也提高了对目标对象进行跟随或者拍摄的稳定性,进一步保证了该方法的实用性,有利于市场的推广与应用。
