具体实施方式
本公开实施列提供一种媒体监播的方法、装置、***及存储介质，以解决现有技术中存在的上述技术问题。
为了更好的理解上述技术方案，下面通过附图以及具体实施例对本公开技术方案做详细的说明，应当理解本公开实施例以及实施例中的具体特征是对本公开技术方案的详细的说明，而不是对本公开技术方案的限定，在不冲突的情况下，本公开实施例以及实施例中的技术特征可以相互组合。
需要理解的是，在本发明实施例的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。在本发明实施例的描述中“多个”，是指两个或两个以上。
本发明实施例中的术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后 关联对象是一种“或”的关系。
请参见图1为本公开实施例提供的一种媒体监播***的结构示意图，该媒体监播***包括：
显示单元1，被配置为播放标识有校验信息的待播放节目；待播放节目通常包括多个节目，每个节目中包括对应的校验信息，待播放节目包括图片/图像视频。
图像采集单元2，被配置为采集显示单元1播放的当前实播节目上对应节目校验区的图像信息；其中，当前实播节目为待播放节目中当前正在播放的节目。在媒体监播***中，显示单元1、图像采集单元2可以为一个，也可以为多个，且显示单元1与图像采集单元2一一对应。
媒体监播单元3，被配置为从各图像采集单元2获取对应的图像信息，并执行媒体监播方法；该媒体监播方法在后续的方法实施例中进行介绍。
图1中示出了多个显示单元1，显示单元1可以是广告机的屏幕、多媒体设备的屏幕。在每个显示单元1中与节目校验区对应的固定位置(图1中以虚线区域示意)被配置为显示显示单元1的显示画面中节目校验区的校验信息，根据校验信息可以获知：当前应播节目的节目标识、节目顺序、播放该节目的设备标识、所属节目播出计划的标识、计划类型等。
在显示单元1中与节目校验区对应的固定位置设置有图像采集单元2，该图像采集单元2可以是图像拍摄设备，如摄像头，图像拍摄设备可以安装在显示单元1表面与指定区域正对的位置，通过在显示单元1表面安装图像拍摄设备，便于对已有的显示单元1进行监播。
图像采集单元2还可以是图像传感器，如光学传感器，图像传感器可以设置在显示单元1的指定区域，作为显示单元1中显示面板的组成部分之一，通过将图像传感器设置在显示单元1内，可以使显示单元1更美观。
图像采集单元2将采集的节目校验区的图像信息传输给媒体监播单元3，通过媒体监播单元3中的媒体监播方法，实时监播显示单元1播放节目是否正常，以便在播放不正常时进行相关处理，以提高显示单元1播出节目的准 确性。该实际显示信息可能是二维码对应的第一字符串信息，也可能是确定显示单元1出现黑屏的黑屏信息，还可能是确定节目校验区中没有二维码、或存在未识别二维码的信息等。
显示单元1、图像采集单元2、媒体监播单元3可以是相互独立的设备，也可是同一设备，如它们可以位于同一广告机中，也可以是一个显示单元1和一个图像采集单元2同属一个广告机，多个广告机对应一个媒体监播单元3；还可以是显示单元1属于一个广告机、图像采集单元2为单独的一个设备，媒体监播单元3也为一个单独的设备。当然媒体监播单元3还可以根据功能划分为不同的多个设备。
请参见图2为本公开实施例提供的另一种媒体监播***的结构示意图，媒体监播***还包括：
数据缓存单元4，被配置为存储从图像采集单元2获取对应显示单元1的显示画面中节目校验区的图像信息，并提供给媒体监播单元3。
当显示单元1的数量众多，相应众多图像采集单元2采集的图像信息的数据量也将十分庞大，通过在监播***中设置数据缓存单元4存储各图像采集单元2采集的图像信息，可以让媒体监播装单元3根据自身的数据处理能力从数据缓存单元4读取图像信息，从而能够防止数据拥塞，提高媒体监播单元3的稳定性。
请参见图3为本公开实施例提供的另一种媒体监播***的结构示意图。媒体监播***还包括：
媒体编辑单元5，被配置为编辑待播放节目，并在待播放节目的节目校验区设置对应节目的校验信息，并将设置有校验信息的待播放节目提供给显示单元1，以及将每个节目独一的校验信息提供给媒体监播单元3。
例如，用户需要制定某日在某条地铁沿线的广告机中需要播放的广告节目，可以在媒体编辑单元5中编辑待播放节目(如包括节目1～10)，并在节目1～10的节目校验区设置对应的校验信息，将设置有校验信息的待播放节目提供给显示单元1进行播放，以及将每个节目对应的校验信息提供给媒体监播 单元3。
在介绍完媒体监播***的结构组成后，下面将对上述媒体监播***中媒体监播单元3使用的媒体监播方法进行介绍。
请参见图4为本公开实施例提供的媒体监播方法的流程图，基于同一发明构思，本公开一实施例中提供一种媒体监播的方法，该方法的处理过程如下。
步骤401：获取当前被监播的显示屏的显示画面中节目校验区的图像信息；其中，节目校验区被配置为显示显示屏当前应播节目对应的校验信息。
显示屏(即显示单元1)在播放节目时，媒体监播单元3可以直接从图像采集单元2获取显示屏的显示画面中节目校验区的图像信息，也可以通过其它与图像采集单元2连接的设备获取显示屏的显示画面中节目校验区的图像信息。该图像信息可能是二维码图像，也可能是非二维码图像，如文字、符号、黑屏等的图像。
在获得图像信息后便可执行步骤402。
步骤402：对图像信息进行识别，确定表征显示屏中当前应播节目的实际显示信息。
对图像信息进行识别，确定表征显示屏中当前应播节目的实际显示信息，可以通过下列方式实现：
检测图像信息中是否包含二维码；若确定图像信息中包含二维码，对图像信息中包含的二维码进行解析，获得解析结果；将解析结果确定为实际显示信息。
请参见图5和图6，图5为本公开实施例提供的显示屏播放当前应播节目的示意图，图6为本公开实施例提供的显示屏中节目校验区的图像信息的示意图。
显示屏(对应的设备标识为“DEVICE1”)当前应播节目为播放“公筷行动”(节目标识为“公益广告2”)的公益广告，此公益广告位于节目播放计划1(标识为“JX1”)中，排序为第3个节目(对应标识为“03”)，上述信息构 成第二字符串(“JX1，03，公益广告2，DEVICE1”)，根据该第二字符串生成的二维码作为校验信息，显示在当前应播节目的节目校验区。图像采集单元对显示屏的显示画面中节目校验区进行图像采集，得到对应的图像信息(如图6所示，也就是一个图片)，并传输给媒体监播单元。
媒体监播单元检测该图像信息中是否包含二维码，检测结果为包含，对图像信息中包含的二维码进行解析，得到解析结果为：“JX1,03,公益广告2，DEVICE1”，将之确定为表征显示屏中当前实播节目的实际显示信息。
一种可能的实施方式，检测图像信息中是否包含二维码，可以采用下列方式实现：
检测图像信息中包含的角点的总数量；判断总数量是否大于第一阈值；若为是，确定图像信息中包含二维码。
一种可能的实施方式，检测图像信息中包含的角点的总数量之后，若总数量小于或等于第一阈值，确定图像信息中未包含二维码；将无二维码的信息确定为实际显示信息。
检测图像信息中包含的角点的总数量可以采用角点检测算法实现。
例如，请参见图7为本公开实施例提供的一种图像信息的示意图。假设显示屏所在的设备被黑客入侵，将显示屏显示的内容篡改为其它内容，此时采集到的节目校验区的图像信息如图7所示，假设第一阈值为60。
采用角点检测算对图7所示的图像信息进行检测，确定其中包含的角点的总数量为4(即小于60)，可以确定图7所示的图像信息中未包含二维码，此时将无二维码的信息确定为表征显示屏中当前实播节目的实际显示信息。
又如，采用角点检测算对图6所示的图像信息进行检测，确定其中包含的角点的总数量为200(大于60)，可以确定图6所示的图像信息中包含二维码。
由于显示屏在显示时可能出现黑屏，因此还可以通过图像信息确定显示屏是否黑屏。
确定图像信息中未包含二维码之前或之后，还可以通过下列方式确定显 示屏是否黑屏：
对图像信息进行二值化处理，获得对应的二值化图像；根据二值化图像中白色区域的占比值是否小于预设占比阈值，确定显示屏是否为黑屏；在确定显示屏为黑屏后，将黑屏信息确定为实际显示信息。
例如，将图像信息二值化处理为二值化图像后，可以确定白色区域的面积，将白色区域的面积与二值化图像的面积比，确定为白色区域的占比值，判断该占比值是否小于预设占比阈值(假设为0.005)，若小于确定显示屏黑屏，将黑屏信息确定为实际显示信息。由于白色区域中的像素都是白色像素，因此在上述处理过程中，也可以统计二值化图像中白色像素的数量，将白色像素的数量与二值化图像中像素的总数量的比值作为白色区域的占比值。
一种可能的实施方式，对图像信息进行二值化处理，获得对应的二值化图像，可以通过下列方式实现：
将图像信息中，像素的实际灰度值大于第二阈值的像素设置为白色像素；实际灰度值小于第二阈值的像素设置为黑色像素，得到二值化图像。
例如，假设第二阈值为M，通过将图像信息中像素的实际灰度值大于M的像素设置为白色像素，其余的设置为黑色像素，便能得到二值化图像。
第二阈值的取值范围为0.005～0.01。
第二阈值可以为经验值，也可以为图像信息中最大灰度值和最小灰度值的差值与预设系数的积。
例如，从图像信息中获取其中的最大灰度值和最小灰度值，将它们的差值与预设系数的积确定为第二阈值。用公式可以表示为：
M＝(G max-G min)×k；
其中，M为第二阈值，G max、G min分别为图像信息中的最大灰度值、最小灰度值，k为预设系数，k的取值范围为0.4～0.6。
若确定图像信息中包含二维码，对图像信息中包含的二维码进行解析，获得解析结果，可以采用下列方式实现：
对图像信息中包含的二维码进行解析，获得第一字符串；判断第一字符 串是否为乱码，若是乱码，则确定第一字符串为无效字符串，并将未识别二维码的信息作为解析结果；若确定第一字符串不是乱码，则将第一字符串作为解析结果。
例如，对图像信息中包含的二维码进行解析，得到的第一字符串是乱码，可以确定第一字符串为无效字符串，相应的图像信息中包含的二维码为未识别二维码，此时将未识别二维码的信息作为解析结果，确定实际显示信息为未识别二维码的信息。若图像信息为图6所示的图像信息，解析出的第一字符串为“JX1，03，公益广告2，DEVICE1”，可以确定该第一字符串不是乱码，将“JX1，03，公益广告2，DEVICE1”作为图像信息中包含的二维码的解析结果，确定实际显示信息为“JX1，03，公益广告2，DEVICE1”。
在获得显示屏的实际显示信息后，便可执行步骤403。
步骤403：根据校验信息对实际显示信息进行校验，若校验通过则确定显示屏为正常播放，若校验不通过则确定显示屏为非正常播放。
在本公开提供的实施例中，通过获取当前被监播的显示屏的显示画面中节目校验区的图像信息；该节目校验区被配置为显示显示屏中当前应播节目对应的校验信息；进而对图像信息进行识别，确定表征显示屏中当前实播节目的实际显示信息；并根据校验信息对实际显示信息进行校验，若校验通过则确定显示屏为正常播放，若校验不通过则确定所述显示屏为非正常播放，从而可以通过节目校验区中显示的内容对显示屏实播节目进行监播，提高节目播出的准确性。并且，通过对显示屏的节目校验区的图像信息进行识别，还可以及时发现显示屏存在的异常，如黑屏、被入侵(无二维码、有二维码但未识别)等，进而可以提示相关技术人员进行处理，提高节目播出的准确性。
一种可能的实施方式，根据校验信息对实际显示信息进行校验，可以采用下列方式实现：
用校验信息与实际显示信息进行比对；若实际显示信息与校验信息一致，则校验通过；若实际显示信息与校验信息不一致，则校验未通过。
上述比对过程中，若校验信息和实际显示信息是同类型的信息(如均为图像信息)，则可以通过计算两个图像的相似度，来确定校验是否通过；若校验信息与实际显示信息不是同类型的信息，如校验信息为二维码，实际显示信息为字符串，则可以将它们转换为相同类的信息后再进行比对。
例如，以图5中的例子为例，通过采集的节目校验区的图像信息，识别出表征显示屏中当前实播节目的实际显示信息为“JX1，03，公益广告2，DEVICE1”，而此显示屏当前应播节目的校验信息(为二维码)对应的第二字符串为“JX1，03，公益广告2，DEVICE1”，通过比较可以得知第二字符串与实际显示信息一致，确定校验通过，说明显示屏当前实播节目与当前应该播节目一致，显示屏为正常播放。
又如，在一段时间后，过采集的节目校验区的图像信息，识别出表征显示屏中当前实播节目的实际显示信息为“黑屏”，将第二字符串“JX1，03，公益广告2，DEVICE1”与“黑屏”比较，确定第二字符串与实际显示信息不一致，确定校验未通过，说明显示屏当前实播节目与当前应该播节目不一致，显示屏为非正常播放。
一种可能的实施方式，校验未通过之后，还可以根据实际显示信息，确定显示屏的当前状态。当前状态可以为黑屏状态，也可以为节目播出错误状态，还可以为其它状态。
例如，上一例子中，确定校验未通过后，还可以根据实际显示信息确定显示屏的当前状态为黑屏状态。
根据实际显示信息，确定显示屏的当前状态，可以通过下列方式实现：
若实际显示信息为黑屏信息，则确定显示屏的当前状态为黑屏状态，并发送警示信息；若实际显示信息为无二维码信息、或未识别二维码的信息，则确定显示屏的当前状态为节目播出错误状态(非正常播放)，并发出警示信息及关闭显示屏。
例如，实际显示信息为黑屏信息时，可以确定显示屏的当前状态为黑屏，并发出警示信息，该警示信息可以是声光信息、短信息、文字信息等，相关 技术人员在获取上述警示信息后可以及时排除该显示屏存在的故障。
实际显示信息为无二维码，或有未识别的二维码信息后时，可以确定显示屏当前状态为节目播出错误状态，并发出警示信息以及关闭显示屏，这样可以防止播出错误节目，相关技术人员也可以根据该警示信息，及时查找节目播错的原因，让显示屏播出正确的节目。
一种可能的实施方式，若多次对实际显示信息进行校验，均为校验失败，则发送警示信息。
通过多次对显示屏的实际显示信息进行校验，在多次校验均失败的情况下才发送警示信息，这样可以防止偶发性错误影响显示屏的正常播放，从而提高显示屏节目播放的准确性。
一种可能的实施方式，根据校验信息对实际显示信息进行校验之前，还包括：
获取针对显示屏制定的节目播出计划；从节目播出计划中提取当前应播节目的第二字符串；其中，第二字符串包括校验当前应播节目真实性的相关信息；根据第二字符串生成二维码，作为校验信息。将该校验信息设置在待播出节目中对应节目的节目校验区中，在播放该节目时，可以在节目校验区显示对应的校验信息。
例如，以图5为例，当用户利用媒体编辑单元编辑待播出节目及节目编排计划后，媒体编辑单元将节目播出计划发送给媒体监播单元，媒体监播单元从节目编排计划中提取包括校验当前应播节目的真实性的相关信息：“JX1，03，公益广告2，DEVICE1”，将其作为第二字符串，并据此生成二维码，作为校验时使用的校验信息。
媒体编辑单元生成待播出节目中每个节目的校验信息的过程与此相似。当然待播出节目中每个节目的校验信息也可以由媒体编辑单元直接提供给媒体监播装置，这样媒体监播装置只需根据节目标识获取对应的校验信息进行校验即可。
