具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实 施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
请参见图1，其为本申请一实施例提供的一种显示设备故障检测装置的结构示意图。如图1所示，显示设备故障检测装置100包括：服务器110、显示设备130、图像采集设备150。
显示设备130例如为LED(Light Emitting Diode，发光二极管)同步系统、LED异步系统、LCD(Liquid Crystal Display，液晶显示器)显示系统、PDP(Plasma Display Panel，等离子显示板)显示系统等。例如LED同步系统包括PC机、发送卡、接收卡以及LED灯板。LED灯板具有显示区域。显示设备130可在显示区域播放文字、图像、视频、声音等各种数据信号。此处的显示设备130可以为一个或多个。
服务器110可例如为一个管理资源并为用户提供服务的计算机。服务器110上可存储大量数据例如图像采集设备150上传的图像。服务器110上设置有选择列表以列出所有的显示设备130。服务器110上存储有所有显示设备130的设备信息，例如与显示设备130对应的存储地址等。此处的存储地址优选为FTP(File Transfer Protocol，文件传输协议)地址以便于图片等文件的传输、存储，当然也可以为其它类型的存储地址。用户可以登录服务器110从显示设备列表中选定一个或多个待检测显示设备作为目标显示设备，并可显示、查看所述目标显示设备的设备信息。具体地，用户可以通过应用程序输入相应指令、在应用程序内进行相应操作等选择 显示设备作为目标显示设备。所述应用程序例如iCare软件，可是安装在服务器110上，也可以是安装在与服务器110连接的用户终端上，以用于接收图片、管理图片、分析图像数据以及根据图像数据分析结果判断目标显示设备是否存在显示异常，并在目标显示设备存在显示异常时提醒用户等。当然，也可以在服务器110以及其上的应用程序内设定相应的显示设备选择策略，例如按照显示设备130的所处区域或距离等进行选择，或者随机自动选择等。
图像采集设备150可例如为CCD(Charge Coupled Device，电荷耦合器件)摄像机。图像采集设备150自带操作系统，可例如通过无线或有线网络连接服务器110。图像采集设备150与显示设备130一一对应安装。开启图像采集设备150使得图像采集设备150的镜头对准显示设备130的显示区域，以采集显示设备130的显示区域的播放画面时得到对应的包含显示区域在内的图像。
在采集图像之前，图像采集设备150需要设置相应参数，例如服务器110的链接地址、登录用户名以及密码等以连接服务器110。另外，还需要在图像采集设备150上设置所述存储地址以绑定显示设备130和图像采集设备150。此外，还需要校正图像采集设备150的系统时间，开启定时采集图像功能，配置图像采集规则。所述图像采集规则可例如为设置图像采集设备150按照预设时间间隔采集图像，如间隔30秒采集图像一次，也可以为设定图像采集设备150在预定时间连续拍摄，如在上午8：00连续采集5张图片，又或者是在图像采集设备150上设定图像采集时间表并按照所 述图像采集时间表采集图像。此外，还需要设置图像上传时间。启动定时采集图像功能后，图像采集设备150会自动按照设定的采集规则采集包含显示设备130的显示区域在内的图像，并按照设定的图像上传时间将采集的图像上传至服务器110上的所述存储地址。值得一提的是，用户可以通过图像采集设备150的生产厂商提供的配置网址或手机应用程序来完成图像采集设备150的所有设置工作。当然，用户还可以通过服务器110以及安装于服务器110上的应用程序控制图像采集设备150按照预设的采集规则进行图像采集。
承上述，显示设备130可在其显示区域内播放正常画面例如广告商发布的广告视频，也可以在播放检测画面以检测显示设备的显示状况。
当显示设备130的显示区域播放正常画面时，图像采集设备150采集所述正常画面得到的常规图像，并按照预设的上传时间规则在相应的时间将所述常规图像上传至服务器110上的存储地址。此处的常规图像可为一幅或多幅图像。在获取图像采集设备150上传所述常规图像后，用户可以在服务器110上进行相应操作在服务器110的所述存储地址中选取任意一幅所述常规图像作为测试图像，并在所述测试图像中标定出所述测试图像中与显示设备130的显示区域对应的标定区域，然后记录所述标定区域的数据信息，即完成所述标定区域的标定。由于显示设备130的显示区域可能部分或完全出现在所述测试图像中，因此所述标定区域小于或等于显示设备130的显示区域在所述测试图像中的对应区域大小。
当需要检测显示设备130的显示状况时，可在显示设备130的显示区 域显示检测画面。显示设备130可例如下载、安装有检测画面显示程序。所述检测画面显示程序可例如从服务器110下载得到，当然也可以从其他地方获取得到，本申请不以此为限。在所述检测画面显示程序内可预先设定检测画面序列的播放参数例如开始播放播放时间、播放时长等。当然，用户还可以根据自身需要、并通过服务器110以及安装于服务器110上的应用程序对所述检测画面显示程序中预设的播放参数进行修改或调整。安装在显示设备130上的所述检测画面显示程序自动或者在服务器110的控制下在预设时间例如上午8：00在显示设备130的显示区域内定时播放检测画面序列，播放时长为2分钟。此处的检测画面序列用于检测显示设备130是否存在显示异常。检测画面序列优选为包括依序播放的第一画面、第二画面和第三画面。所述第一画面和所述第三画面为相同画面，所述第一画面和第二画面为不同画面。优选地，所述第二画面为黑色纯色画面。所述第一画面为彩色纯色画面。进一步地，所述第一画面为浅色纯色画面例如浅蓝色(RGB：193，210，240)纯色画面、浅紫色(RGB：218，112，214)纯色画面。用户可进一步设定第一画面、第二画面以及第三画面的播放时长例如分别为40秒。当然也可以为第一画面、第二画面以及第三画面设定不同的播放时长，例如第一画面和第三画面分别为30秒，第二画面的播放时长为60秒等，此处不以此为限。通常情况下，检测画面序列中每一个画面的播放时长应大于或等于图像采集设备150的图像采集间隔时间。
当显示设备130的显示区域播放检测画面序列时，通过检测画面序列播放时长和图像采集设备150的图像采集时间的配合，图像采集设备150 可依序采集所述检测画面序列例如依序播放的第一画面、第二画面和第三画面得到的对应的检测画面图像。根据不同的检测画面序列播放时长和图像采集设备150的图像采集时间的配合，可以得到不同数量的检测画面图像，也以是一幅检测画面图像或者多幅检测画面图像。优选地，此处的检测画面图像为两幅或三幅检测画面图像组成的检测画面图像组。所述检测画面图像组例如包括一对应第一画面或第三画面的第一检测画面图像和一对应第二画面的第二检测画面图像即两幅图像，或者包括一对应第一画面的第一检测画面图像、一对应第二画面的第二检测画面图像以及一对应第三画面的第三检测画面图像即三幅图像。在得到所述常规图像和所述检测画面图像(组)后，图像采集设备150按照预定的图像上传时间将所述常规图像和所述检测画面图像(组)上传至服务器110的所述存储地址中。通过特定的检查画面序列以及播放时长与图像采集时间的配合，可以确保图像采集设备150能够采集到一幅黑色画面对应的图像和至少一幅浅色纯色画面对应的图像，以更加准确地判断显示设备130的显示区域是否存在显示异常。
在接收到图像采集设备150上传所述检测画面图像后，服务器110从所述存储地址中存储的大量图片中识别出所述检测画面图像，并筛选出合适的所述检测画面图像作为待检测图像。具体地，首先服务器110根据图像采集时间识别出存储地址中的采集时间位于检测画面序列播放时间段内的检测画面图像。当识别出的所述检测画面图像的数量为两幅时，即说明图像采集装置130采集的所述检测画面图像的其一对应于第一画面或第三 画面的检测画面图像，另一幅对应第二画面的检测画面图像，此时服务器110将所述两张检测画面图像均作为待检测图像。当识别出的所述检测画面图像的数量为三幅时，则说明图像采集装置130采集的所述检测画面图像其一对应于第一画面，其二对应第二画面，其三对应第三画面，此时服务器110将对应于第一画面或第三画面的检测画面图像、和对应于第二画面的检测画面图像作为待检测图像。
之后，服务器110对所述待检测图像中的相应区域中的图像数据进行处理。具体地，服务器将所述待检测图像中与所述标定区域相对应的图像区域确定为待检测区域，然后对所述待检测区域进行图像数据处理，例如对所述待检测区域内的所有像素进行逐点分析并得到图像数据处理结果。此处的图像数据处理方法可例如参考现有技术中的异常灯点检测方法等。具体地，当所述待检测图像为与所述第二画面(黑色纯色画面)对应的图像时，其处理结果例如包括所述待检测图像中的所述待检测区域内存在异常亮点或亮块，以及所述待检测图像中的所述待检测区域内不存在异常亮点或亮块两种。当所述待检测图像为与所述第一画面(彩色纯色画面)或所述第三画面(彩色纯色画面)对应的图像时，其处理结果例如包括：所述待检测图像中的所述待检测区域内存在异常暗点或暗块，以及所述待检测图像中的所述待检测区域内不存在异常暗点或暗块两种。
之后，服务器110根据图像数据处理结果来判断所述待检测图像中的所述待检测区域是否存在异常显示区域。当处理结果为任何一幅所述待检测图像中的所述待检测区域存在异常显示区域(例如异常亮/暗点和/或异常 亮/暗块)时，则可确定对应的显示设备130的显示区域存在显示异常。当处理结果为所有的所述待检测图像中的所述待检测区域均不存在异常显示区域时，则可确定对应的显示设备130的显示区域不存在显示异常。如此一来，通过对所述待检测图像中的所述待检测区域进行图像数据处理并根据图像数据处理结果自动判断显示设备130的显示区域是否存在显示异常故障，这样可以极大地提高显示设备故障检测的准确率。
当确定显示设备130的显示区域存在显示异常时，服务器110通过邮件、微信或者短信方式输出故障检测结果或者发出故障警报以提醒用户进行相应处理。当然，在通过邮件、微信或者短信方式发送故障检测结果之前，需要设置好用户接收邮件的邮箱地址、微信号或者接收短信的手机号码。此处的故障检测结果可例如包括所述检测画面图像或者两幅检测画面图像和故障说明。所述故障说明可例如为“显示屏右上角区域存在异常显示区域”。发出故障警报提醒用户可具体为通过设置与所述目标显示设备相对应的警报灯，并在确定所述目标显示设备的显示区域存在显示异常时，控制警报灯闪烁以提醒用户。当然，也可以采用其他方式提醒用户，此次不以此为限。
值得一提的是，除了常规图像可以作为测试图像外，图像采集设备150采集并上传的检测画面图像也可以作为测试图像使用，也即测试图像可以为服务器110的存储地址中的包含目标显示设备的显示区域的任意图像。
综上所述，本申请实施例通过设置存储地址绑定显示设备130和图形采集设备150，控制显示设备130在显示区域播放检测画面序列，图像采集 设备150采集检测画面序列得到相应的图像并将所述图像上传至服务器110，再由服务器110对所述图像中的待检测区域进行图像数据处理以判断所述待检测区域内是否存在异常显示区域，并根据图像数据处理结果确定显示设备130的显示区域是否存在显示异常。通过在显示区域播放检测画面序列以确保图像采集设备150能采集到分别与黑色画面和浅色纯色画面对应的两幅检测画面图像并将其作为待检测图像，再通过对所述两幅待检测图像中的所述待检测区域进行图像数据处理并根据图像数据处理结果判断显示设备130的显示区域是否存在显示异常故障，这样可以极大地提高显示设备故障检测的准确率。当显示设备130的显示区域存在显示异常时，通过邮件、微信或短信方式输出故障检测结果给用户或发出故障警报以及时提醒用户对显示设备130进行相应的处理，以确保显示设备130的正常播放，将显示设备130的故障造成的影响降至最低。另外，通过采用服务器110自动分析图像是否存在播放故障而不需要人眼来观察图像是否出现播放故障，从而可以进一步提高检测效率和准确率、降低人工检测成本。再者，采用服务器来存储大量图像数据，为用户节省购买大存储量硬件的成本。
