Abstract
提供了用于智能地记录视频数据流的系统和方法。一些方法可以包括确定摄像机的视场的第一高分辨率视频数据流中的感兴趣的区域是否包括运动。当感兴趣的区域包括运动时,可以从第一高分辨率视频数据流中裁剪感兴趣的区域以形成感兴趣的区域的第二高分辨率视频数据流,以及可以将视场中的非感兴趣的区域的第一高分辨率视频数据流转换成非感兴趣的区域的第一低分辨率视频数据流。当感兴趣的区域不包括运动时,视场的第一高分辨率视频数据流可以被转换成视场的第二低分辨率视频数据流。
Description
技术领域
本发明涉及视频监视系统。更具体地,本发明涉及用于在视频监视系统中智能地记录视频数据流的系统和方法。
背景技术
已知的视频监视系统可以包括数以千计的摄像机,其中大部分是IP摄像机,其可以将视频数据流保存到网络视频记录器。然而,在已知的视频监视系统中,网络视频记录器的硬盘容量是一个问题。例如,许多视频数据流以高分辨率保存,但这些保存的视频数据流通常不会为用户增加任何价值。
鉴于上述情况,存在对于改进的系统和方法的持续的、正在进行的需求。
附图说明
图1是根据所公开实施例的系统的框图。
具体实施方式
虽然本发明可以有许多不同形式的实施例,但是在理解本公开应被视为本发明的原理的范例的情况下,在附图中示出并且在本文中详细描述其具体实施例。没有意图将本发明限制于具体图示的实施例。
本文公开的实施例可以包括用于在视频监视系统中智能地记录视频数据流的系统和方法。有利地,本文公开的系统和方法可以以低分辨率智能地记录和保存不需要的视频数据流或视频数据流中的非感兴趣的区域,并且以高分辨率记录和保存视频数据流中的感兴趣的区域,以便优化硬盘利用率。此外,本文公开的系统和方法可以有利地独立地并且以不同的分辨率记录和保存来自单个摄像机的多个视频数据流,以优化带宽使用。
根据所公开的实施例,本文公开的系统和方法可以接收标识摄像机的视场中的感兴趣的区域的用户输入。例如,在一些实施例中,感兴趣的区域可包括其中具有高运动或活动概率的区域,诸如例如门区域、窗口区域或人行道区域。
在操作期间,摄像机可以将摄像机的视场的第一高分辨率视频数据流发送到记录设备,诸如例如网络视频记录器或移动的或基于云的记录器,并且本文公开的系统和方法可以针对感兴趣的区域中的运动或活动分析第一高分辨率视频数据流的每个帧。当检测到运动或活动时,本文公开的系统和方法可以逐帧地从第一高分辨率视频数据流中裁剪感兴趣的区域,以形成仅感兴趣的区域的第二高分辨率视频数据流,并且可以逐帧地将感兴趣的区域之外的第一高分辨率视频数据流的剩余部分(即,非感兴趣的区域)转换成低分辨率压缩视频数据流。在一些实施例中,本文公开的系统和方法可以将第二高分辨率视频数据流和低分辨率压缩视频数据流二者记录为来自摄像机的多个且单独的视频数据流。此外,当未检测到运动或活动时,本文公开的系统和方法可以逐帧地将整个第一高分辨率视频数据流转换成摄像机的视场的低分辨率解压缩视频数据流。
在一些实施例中,本文公开的系统和方法可以校准投资成本,以用于将摄像机的视场的第一高分辨率视频数据流中的一些或全部转换成感兴趣的区域的第二高分辨率视频数据流或转换成视场或非感兴趣的区域的低分辨率压缩视频数据流。响应于此,在一些实施例中,本文公开的系统和方法可以向用户传输通知消息,建议根据这样的校准进行转换。附加地或替代地,响应于此,在一些实施例中,本文公开的系统和方法可以将操作指令传输到摄像机,例如,当摄像机是PTZ摄像机时,以调整摄像机的平移、倾斜或变焦操作并获得感兴趣的区域的更清晰的图像。
如以上所解释的,在一些实施例中,本文所公开的系统和方法可以独立地并且以不同分辨率记录和保存来自单个摄像机的多个视频数据流。在这方面,当记录或保存每个视频数据流时,本文公开的系统和方法可以将QR码与来自摄像机或在记录设备上的每个视频数据流的每个帧相关联,并且QR码可以被特定于摄像机或特定于记录设备。附加地或替代地,在一些实施例中,本文公开的系统和方法还可以将QR码与在视频数据流中检测到的警报相关联。
QR码可以包括数据,诸如例如摄像机的MAC ID、随机密钥和记录设备的MAC ID。在一些实施例中,QR码可以嵌入在每个视频数据流的每个帧或每个I帧中。附加地或替代地,在一些实施例中,QR码可以是索引文件的一部分并且用作外部文件参考。因此,在一些实施例中,本文公开的系统和方法可以基于QR码搜索记录设备,或者可以在从记录设备的存储器检索视频数据流时解码QR码。
图1是根据所公开实施例的系统100的框图。如图1中所见,摄像机110可以生成摄像机110 的视场的第一高分辨率图像120,并且本文公开的系统和方法可以针对视场内的感兴趣的区域122中的运动或活动而分析第一高分辨率图像120。当检测到运动或活动时,本文公开的系统和方法可以从第一高分辨率图像120中裁剪感兴趣的区域122以形成感兴趣的区域122的第二高分辨率图像130,并且可以将第一高分辨率图像120中的感兴趣的区域122之外的非感兴趣的区域124转换成低分辨率压缩图像140。
应当理解,本文公开的摄像机和记录设备中的每一个可以包括相应的收发器设备、相应的存储器设备和相应的用户接口设备,其中每一个可以与相应的控制电路、相应的可编程处理器和相应的可执行控制软件通信,如本领域普通技术人员将理解的那样。相应的可执行控制软件可以存储在暂时或非暂时性计算机可读介质上,所述暂时或非暂时性计算机可读介质包括但不限于本地计算机存储器、RAM、光学存储介质、磁性存储介质、闪速存储器等。在一些实施例中,相应的控制电路、相应的可编程处理器和相应的可执行控制软件可以执行和控制本文公开的一些或所有方法。
尽管上面已经详细描述了一些实施例,但是其他修改也是可能的。例如,上述逻辑流程不要求所描述的特定次序或顺序次序来实现期望的结果。可以提供其他步骤,可以从所描述的流程中去除步骤,并且其他组件可以被添加到所描述的系统或从所描述的系统中去除。其他实施例可以在本发明的范围内。
从上述内容,将观察到在不脱离本发明精神和范围的情况下,可以实现许多变化和修改。应当理解,并不意图或推断关于本文所述的特定系统或方法的限制。当然,意图在于涵盖所有这样的修改为落入本发明的精神和范围内。
