具体实施方式
下面将结合本公开实施例中的附图，对本公开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公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，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，都属于本公开保护的范围。
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。
应当理解，在此本公开说明书中所使用的术语仅仅是出于描述特定实施例的目的而并不意在限制本公开。如在本公开说明书和所附权利要求书中所使用的那样，除非上下文清楚地指明其它情况，否则单数形式的“一”、“一个”及“该”意在包括复数形式。
相关技术中，为了达到补录的目的，需要视频管理服务器从摄像头设备的存储卡中下载对应的缺失录像，由于摄像头设备性能的局限性，由视频管理服务器直接向摄像头设备 下载录像数据的耗时较长，导致补录效率较低。
本公开实施例提供了一种录像数据补录方法、云存储服务器、系统及存储介质。其中，该录像数据补录方法可应用于中心云存储服务器中，该中心云存储服务器包括承载边缘计算数据中心的云存储服务器。该录像数据补录方法可应用于视频安防系统、视频管理系统、视频智能分析系统等场景。
相关技术方案中，通过从数据库定时查询分析出存储服务器的录像数据缺失信息，再到网络摄像头设备的存储SD(Secure Digital)卡中去下载对应缺失录像，来达到补录的目的。该技术方案存在的问题在于，由于网络摄像头设备性能的局限性，在存在多段录像数据缺失时，直接向网络摄像头设备下载将耗时较长，效率较低。
基于此，本公开实施例提供了一种录像数据补录方法，具有基于边缘云存储计算实现录像补录的功能，由于边缘计算的高并发、高性能、高可靠等特性，决定了录像补录功能可以比直接从摄像头设备补录有更高效的补录效率，解决了录像数据缺失场景下的并发补录需求，能够极大的提高录像数据的补录效率。
并且，若存储服务器直接从网络摄像头设备下载录像，无法避免可能产生的原本导致录像数据缺失的通讯中断问题。本公开实施例采用动态添加边缘计算补录功能的方式，在第一录像设备的通讯连接断开时，通过第一录像设备相关联的第二录像设备对第一录像设备的录像数据进行补录，可以实现智能补录功能的补充和更新。
下面结合附图，对本公开的一些实施方式作详细说明。在不冲突的情况下，下述的实施例及实施例中的特征可以相互组合。
请参照图1，图1为本公开实施例提供的一种录像数据补录方法的步骤流程示意图。
如图1所示，该录像数据补录方法包括步骤S101至步骤S103。
步骤S101、根据待补录录像数据的描述信息生成录像补录任务。
其中，待补录录像数据可以包括录像视频数据、录像视频数据的描述信息以及其他数据，录像视频数据例如为多帧图像数据，描述信息可以包括待补录录像数据的标识信息、待补录录像数据的缺失信息(如缺失的录像时间段)、拍摄待补录录像数据的第一录像设备的设备信息、与第一录像设备相对应的边缘云存储服务器的服务器信息等。录像视频数据包括缺失的录像时间段对应的录像数据。
当前，第一录像设备通过网络与中心云存储服务器连接，当第一录像设备与中心云存储服务器之间网络不中断时，中心云存储服务器存储的录像数据是连续的，但当第一录像设备与中心云存储服务器之间的网络出现中断时，中心云存储服务器上存储的录像数据会缺少在断网期间的那一部分内容，导致录像数据不连续，需要确定第一录像设备在断网期间拍摄的录像数据作为待补录录像数据，从而进行录像数据的补录。
在一实施例中，待补录录像数据可以是多个，例如待补录录像数据包括断网期间的多个录像设备拍摄的录像数据。多个待补录录像数据对应的边缘云存储服务器也可以是多个，多个边缘云存储服务器负责批量执行录像补录任务，实现高并发性能要求。因为边缘计算的高并发、高性能、高可靠等特性，能够满足解决了大规模录像设备的录像数据缺失场景下的并发补录需求。
在一实施例中，根据待补录录像数据的描述信息生成录像补录任务之前，还包括：获取多个录像数据的录像时间信息；根据多个录像数据的录像时间信息，确定待补录录像数据。其中，录像时间信息例如包括录像时间段或者录像时间点。需要说明的是，通过多个录像数据的录像时间信息，能够确定缺失的录像时间段，从而能够确定与缺失的录像时间段对应的待补录录像数据，提高待补录录像数据的获取准确性。
其中，录像时间信息包括录像时间段；根据多个录像数据的录像时间信息，确定待补录录像数据，包括：根据多个录像数据的录像时间段，从多个录像数据中确定相邻的两个第二录像数据，其中，相邻的两个第二录像数据的录像时间段不连续；根据相邻的两个第二录像数据的录像时间段，确定缺失录像时间段；将缺失录像时间段对应的录像数据作为待补录录像数据。
需要说明的是，录像时间段包括录像开始时间及录像结束时间，根据录像时间段能够确定录像数据对应录像时长及录像数据大小等信息。根据相邻的每两个录像数据的录像时间段，确定相邻的两个第二录像数据，其中，相邻的前一个录像数据的录像结束时间与后一个录像数据的录像开始时间应当是连续的，若确定存在相邻的两个录像数据的录像结束时间与录像开始时间不连续，则可以确定该相邻的两个录像数据为第二录像数据，且该录像结束时间与录像开始时间不连续的录像时间段为缺失录像时间段，从而能够准确地将缺失录像时间段对应的录像数据确定为待补录录像数据，该待补录录像数据的录像时间段包括该缺失录像时间段。
在一实施例中，获取录像事件对应的多个录像数据的录像时间段，以及该录像事件对应的录像时间区间；根据该录像时间区间和多个录像数据的录像时间段，确定缺失的录像时间段；根据缺失的录像时间段，确定待补录录像数据。其中，录像事件对应的录像时间区间可以包括多个录像数据的录像时间段，需要说明的是，从录像时间区间中确定多个录像数据的录像时间段不包括的多个录像时刻，该多个录像时刻的组合即为缺失录像时间段，能够准确的通过缺失录像时间段确定录像事件对应的待补录录像数据。
示例性的，中心云存储服务器包括存储数据库，中心云存储服务器可以周期性发起录像自动巡检，从存储数据库中批量获取录像数据的描述信息，该描述信息可以包括缺失的录像时间段和第一录像设备的设备信息，中心云存储服务器将该缺失的录像时间段和第一 录像设备的设备信息作为待补录录像数据的描述信息，生成录像补录任务。
步骤S102、将录像补录任务发送至边缘云存储服务器，以供边缘云存储服务器根据录像补录任务获取待补录录像数据。
其中，边缘云存储服务器能够提供边缘存储和边缘计算服务，边缘计算是指在靠近物或数据源头的一侧，采用网络、计算、存储、应用核心能力为一体的开放平台，就近提供最近端服务。其应用程序在边缘侧发起，产生更快的网络服务响应，能够满足补录录像数据在实时业务、应用智能、安全与隐私保护等方面的基本需求。通过边缘云存储服务器能够更加快速和高效的获取待补录录像数据，从而提高录像数据的补录效率。
在一实施例中，将录像补录任务发送至边缘云存储服务器，包括：通过信令网关将录像补录任务发送至边缘云存储服务器。其中，信令网关包括信令交互服务器，信令网关用于承接边缘云存储服务器与中心云存储服务器之间的中继信令消息，中继信令消息例如为录像补录任务，中心云存储服务器通过信令网关将录像补录任务下发给边缘云存储服务器，或者边缘云存储服务器通过信令网关将录像补录任务上报给中心云存储服务器。
在一实施例中，边缘云存储服务器根据录像补录任务获取待补录录像数据，包括：根据录像补录任务，从拍摄录像数据的第一录像设备中获取待补录录像数据。需要说明的是，在一些情况下，第一录像设备与中心云存储服务器之间的网络连接中断，但第一录像设备与边缘云存储服务器之间的网络连接没有中断，因此边缘云存储服务器能够根据录像补录任务，从拍摄录像数据的第一录像设备中获取待补录录像数据，该待补录录像数据包括待补录录像数据，从而提高录像数据的补录效率。
在一实施例中，边缘云存储服务器根据录像补录任务获取待补录录像数据，包括：根据录像补录任务，从拍摄录像数据的第一录像设备或边缘云存储服务器的存储装置中获取待补录录像数据，其中待补录录像数据是由第一录像设备拍摄的。需要说明的是，在一些情况下，在恢复第一录像设备的网络连接之后，第一录像设备会将包括网络连接中断时拍摄的待补录录像数据发送至边缘云存储服务器，以使边缘云存储服务器获取待补录录像数据，并由边缘云存储服务器将该待补录录像数据转发至中心云存储服务器，通过边缘计算技术能够满足录像补录功能对于高并发、高效率的性能需求，极大的提高录像数据的补录效率。
步骤S103、接收边缘云存储服务器发送的待补录录像数据，并根据待补录录像数据进行补录处理。
其中，中心云存储服务器接收边缘云存储服务器发送的待补录录像数据，并将待补录录像数据存储至中心云存储服务器中的存储数据库，从而完成待补录录像数据的补录，由于边缘计算的高并发、高性能、高可靠等特性，高效的解决了录像数据缺失场景下的并发 补录需求，能够极大的提高录像数据的补录效率。
在一实施例中，中心云存储服务器与边缘云存储服务器可合设到同一云端，本实施例对此不做具体限定。
在一实施例中，接收边缘云存储服务器发送的待补录录像数据，包括：通过媒体网关接收边缘云存储服务器发送的待补录录像数据。其中，媒体网关包括媒体链路服务器，媒体网关用于承接边缘云存储服务器与中心云存储服务器之间的码流数据，该码流数据例如为待补录录像数据，边缘云存储服务器通过媒体网关将待补录录像数据发送给中心云存储服务器，从而快速的完成录像数据的补录。
示例性的，如图2所示，摄像头设备作为录像设备输出三路媒体流，三路媒体流可以采用流直存的方式。其中，一路媒体流作为存储流接入边缘云存储服务器，一路媒体流作为存储流接入中心云存储服务器，一路媒体流作为实况流接入媒体服务器，媒体服务器与用户终端、视频管理服务器网络连接。其中，用户终端为用户使用的人机交互工具，包括电话、手机和门户网站等，用于运维管理和录像查看等；视频管理服务器用于存储业务数据和业务逻辑，并根据业务逻辑触发业务流程，在本方案中提供设备和录像管理；边缘云存储服务器用于提供边缘存储和边缘计算服务；中心云存储服务器通过和视频管理服务器进行对接，实现对录像数据的调取和管理。需要说明的是，边缘云存储服务器可以通过(媒体)网关和传输网将待补录录像数据发送给中心云存储服务器，以完成录像数据的补录。
在一实施例中，多个录像数据包括相邻的至少两个第二录像数据，相邻的每两个第二录像数据之间的录像时间段不连续；根据待补录录像数据进行补录处理，包括：将待补录录像数据插入至相邻的两个第二录像数据之间。需要说明的是，相邻的至少两个第二录像数据之间缺失有对应的待补录录像数据，因此可以将待补录录像数据插入至相邻的两个第二录像数据之间，或者由待补录录像数据替换相邻的两个第二录像数据，使得补录处理后的录像数据是连续的，即可完成待补录录像数据的补录处理。
请参照图3，图3为实施本公开实施例提供的录像数据补录方法的一场景示意图，如图3所示，中心云存储服务器10获取待补录录像数据的描述信息，并根据待补录录像数据的描述信息生成录像补录任务；中心云存储服务器10将录像补录任务发送至边缘云存储服务器20；边缘云存储服务器20根据录像补录任务从多个第一录像设备30中获取包括待补录录像数据的待补录录像数据，边缘云存储服务器20将获取的待补录录像数据上传至中心云存储服务器10；中心云存储服务器10接收边缘云存储服务器20上传的待补录录像数据，并根据待补录录像数据进行补录处理。通过中心云存储服务器10与边缘云存储服务器20之间的边缘计算技术能够极大的提高录像数据的补录效率。
上述实施例提供的录像数据补录方法，根据待补录录像数据的描述信息生成录像补录 任务；将录像补录任务发送至边缘云存储服务器，以供边缘云存储服务器根据录像补录任务获取待补录录像数据；接收边缘云存储服务器发送的待补录录像数据，并根据待补录录像数据进行补录处理。通过边缘计算技术能够满足录像补录功能对于高并发、高效率的性能需求，极大的提高录像数据的补录效率。
请参照图4，图4为本公开实施例提供的另一种录像数据补录方法的步骤流程示意图。
如图4所示，该录像数据补录方法包括步骤S201至S205。
步骤S201、当检测到与拍摄录像数据的第一录像设备之间的通讯连接断开时，确定与第一录像设备相关联的第二录像设备。
在一些情况下，中心云存储服务器能够检测第一录像设备的通讯连接是否断开；当检测到与第一录像设备的通讯连接断开时，确定与第一录像设备相关联的第二录像设备。其中，与第一录像设备相关联的第二录像设备可以是安装在第一录像设备环境周围的录像设备，该第二录像设备能够替代第一录像设备完成相关的录像工作。
步骤S202、从第二录像设备拍摄的录像数据中确定待补录录像数据。
在一实施例中，当第一录像设备的通讯连接断开时，无法通过第一录像设备获取第一录像设备拍摄视角下的录像数据，此时可以将第二录像设备拍摄的录像数据作为待补录录像数据，从而完成第一录像设备的录像数据的补录工作，能够有效解决导致录像数据缺失的通讯中断问题，保证录像数据的及时补录。
需要说明的是，从第二录像设备拍摄的该录像数据可以是第一录像设备的通讯连接断开后拍摄得到的，从而保证确定的待补录录像数据的录像时间段能够与第一录像设备的通讯连接断开前拍摄的录像数据的录像时间段连续。
在一实施例中，当检测到与第一录像设备之间的通讯连接恢复时，从第一录像设备拍摄的录像数据中确定待补录录像数据。需要说明的是，当检测到与第一录像设备的通讯连接恢复时，则无需从第二录像设备拍摄的录像数据中确定待补录录像数据，可以将第一录像设备拍摄的录像数据作为待补录录像数据，从而保证录像数据补录的有效性。
其中，从第一录像设备拍摄的录像数据中确定待补录录像数据包括多种方式。一种是将第一录像设备的通讯连接恢复后拍摄的录像数据作为待补录录像数据，从而取代第二录像设备在第一录像设备的通讯连接恢复后拍摄的录像数据，快速恢复第一录像设备拍摄的录像数据的存储；一种是将第一录像设备的连接断开后拍摄得到的录像数据作为待补录录像数据，从而替代第二录像设备补录的录像数据，保证第一录像设备拍摄的录像数据的完整性。
