其中，步骤S11中提到的目标显示屏例如为LED显示屏，提到的显示箱体例如为LED箱体，每个LED箱体例如包括显示控制卡和连接所述显示控制卡的LED模组，每个LED模组由至少一个LED灯板拼接而成。提到的采集图像例如包括每个显示箱体对应的网口序号和箱体序号的图像、或者包括每个显示箱体对应的可识别图像，其中可识别图像可以被识别以获取对应的网口序号和箱体序号。其中，提到的显示控制卡例如为LED显示屏控制系统中的接收卡，又称扫描卡，其例如包括：网口、连接网口的可编程逻辑器件、连接可编程逻辑器件的微控制器和存储器等器件，提到的网口例如为RJ45，提到的存储器例如为易失性存储器SDRAM，提到的可编程逻辑器件例如为FPGA，提到的微控制器例如为MCU。
步骤S12中提到的箱体配置信息例如包括：显示箱体的排列信息以及连线信息，进一步，包括显示箱体的数量。其中，显示箱体的数量可以理解为拼接成为目标显示屏所需要的显示箱体的数量。排列信息可以理解为显示箱体的排列方式。连线信息可以理解为显示箱体之间的连线关系以及显示箱体和显示屏控制器的网口之间的连线关系。举例而言，如图2a所示，解析采集图像可以确认拼接成为目标显示屏所需12块显示箱体，即得到显示箱体的数量；且12块显示箱体按照4*3的排列方式进行排列，即得到显示箱体的排列信息；从上至下的第一排和第二排的显示箱体与显示屏控制器的网口1相连，第三排的显示箱体与显示屏控制器的网口2相连，与网口1相连的显示箱体有8个，第一排的四个显示箱体的连线关系为从左到右，且第一排中最右侧的显示箱体与第二排中最右侧的显示箱体连接，第二排的四个显示箱体依次从右到左连接。与网口2相连的显示箱体有四个，依次从左到右相连，即得到显示箱体的连线信息。
步骤S13中提到的箱体分辨率信息即为组成目标显示屏的每个显示箱体对应的的分辨率。
进一步地，步骤S13例如包括：由显示屏控制器输入的箱体分辨率信息。此处可以理解为，当LED显示屏组装完成之后，显示屏控制器与LED显示屏建立连接，显 示屏控制器存储有LED显示屏中每个LED箱体的箱体分辨率信息，然后显示屏控制器可以响应分辨率获取指令将箱体分辨率信息输入至上位机中。
当然，获取的箱体分辨率信息也可以根据用户的显示屏购买订单获取。提到的显示屏购买订单例如包括用户通过应用程序(APP)购买显示屏的订单，该订单例如包括显示箱体的规格信息，即包括厂商、型号和数量以及显示屏控制器的型号和数量等参数，用户使用该应用程序执行显示屏配置步骤时，可以从显示屏购买订单中获取到的箱体分辨率信息，以用于后续的显示屏配置，如此一来，简化了显示屏配置流程，方便操作。
其中，举例而言，通过显示屏购买订单获取箱体分辨率信息的过程例如为：用户首先通过应用程序输入显示屏使用环境、显示屏预留尺寸和最佳可视距离后，应用程序可以根据用户输入的信息生成至少一个显示屏选购方案，每个显示屏选购方案包括显示箱体的型号和数量以及显示屏控制器的型号和数量，用户在生成的显示屏选购方案中确定一种显示屏选购方案支付下单完成显示屏的选购，即购买了显示箱体和显示屏控制器，在用户对显示箱体和显示屏控制器完成组装之后，需要对目标显示屏进行配置，即应用程序可以根据用户的前述显示屏购买订单获取到目标显示屏中每个显示箱体的箱体分辨率信息。
当然，获取的箱体分辨率信息也可以由用户直接输入，即获取用户从交互界面输入的所述箱体分辨率信息。
其中，提到的交互界面例如为应用程序(APP)的人机交互界面，此应用程序例如执行在手机端、或者电脑端。此处可以理解为，该应用程序提供相关的信息输入窗口，供用户直接输入箱体分辨率信息，如此一来，即使用户使用的目标显示屏并非在线上应用程序进行的选购，同样可以通过本实施例的方法实现显示屏的配置，此外，当用户使用的目标显示屏的选购是在线上应用程序进行时，同样可以在交互界面更改目标显示屏中每个显示箱体的箱体分辨率信息，从而实现显示屏的配置，如此一来，极大地满足用户的需求。
步骤S14中提到的目标配置文件即配置目标显示屏所需要的文件，其中包括显示屏控制器所使用的网口数量、每个网口所连接的显示箱体的数量、显示箱体的排列关系以及连接关系、显示箱体的起始点偏移坐标等信息。此处可以理解为，可以根据箱体配置信息和箱体分辨率信息计算出每个显示箱体所显示图像的起始点偏移坐标即显示坐标，然后在根据显示箱体的起始点偏移坐标以及箱体分辨率信息生成目标配置文件。
步骤S15中提到的显示屏控制器例如为LED显示屏控制系统中的异步发送卡，例 如包括视频源输入接口、连接视频源输入接口的可编程逻辑器件、连接可编程逻辑器件的微控制器、连接可编程逻辑器件的存储器和连接可编程逻辑器件的网口等器件。前述提到的可编程逻辑器件例如为FPGA，提到的微控制器例如为MCU，提到的存储器例如为非易失性存储器，提到的网口例如为RJ45，提到的视频源输入接口例如为HDMI接口。其中，显示屏控制器根据目标配置文件控制目标显示屏进行画面显示。
此外，需要说明的是，目标配置文件的生成除了步骤S14描述的基于箱体配置信息和分辨率信息之外，还可以结合显示箱体的规格信息。提到的显示箱体的规格信息例如包括显示箱体的型号、厂家、箱体大小和箱体点间距等信息。此处考虑的是，不同的厂家所对应的配置文件模板不同，基于显示箱体的规格信息可以直接找到配置文件模板。此处提到的获取显示箱体的规格信息例如显示屏控制器识别出显示箱体的规格信息输入至用户移动设备中、或者通过用户的显示屏购买订单获取、或者由用户在人机交换界面中输入。
在本申请的其他实施例中，显示屏配置方法在步骤S11之前例如还包括：下发箱体定位指令至所述显示屏控制器，以由所述显示屏控制器基于所述箱体定位指令控制所述每个显示箱体显示自身对应的网口序号和箱体序号作为所述指定画面，其中所述网口序号表征所述显示箱体连接所述显示屏控制器的网口对应的网口编号，所述箱体序号表征所述显示箱体在连接的所述显示屏控制器的网口下对应的连接顺序。
其中，提到的箱体定位指令例如由上位机下发。具体地，前述步骤可以理解为，上位机下发箱体定位指令到显示屏控制器，显示屏控制器控制目标显示屏中每个显示箱体显示自己所对应的网口序号和箱体序号，即自己所连接显示屏控制器的网口编号和该网口下自己所对应的箱体连接顺序。举例而言，如图2a所示，目标显示屏由12块显示箱体拼接而成，且该12块显示箱体由显示屏控制器的网口1和网口2带载，每个网口连接6块显示箱体，每个显示箱体显示画面的格式例如为“网口序号-箱体序号”，但本申请并不以此为限，图2a示意的显示箱体显示的1-1表示对应的显示箱体连接显示屏控制器的网口1，且为该网口1下的第一个显示箱体，显示箱体显示的1-2表示该显示箱体连接显示屏控制器的网口1，且为该网口1下的第二个显示箱体，显示箱体显示的2-3表示显示箱体连接显示屏控制器的网口2，且为该网口2下的第三个显示箱体，其他显示箱体同理，在此不再赘述。
通过控制每个显示箱体显示自身对应的网口序号和箱体序号，有助于操作者直观地了解显示箱体之间排序和连接关系以及显示箱体与显示屏控制器之间的连接关系，便于后续操作。
在本申请的其他实施例中，显示屏配置方法在步骤S11之前例如还包括：下发箱 体定位指令至所述显示屏控制器，以由所述显示屏控制器基于所述箱体定位指令控制所述每个显示箱体显示自身对应的可识别图像作为所述指定画面，其中每个可识别图像可被识别获取对应显示箱体的网口序号和箱体序号。
其中，提到的可识别图像例如包括二维码、条形码等表达信息的可识别图像。具体地，前述步骤可以理解为，上位机下发箱体定位指令到显示屏控制器，显示屏控制器控制目标显示屏中每个显示箱体显示自己所对应的可识别图像，例如显示一个二维码，该二维码被识别以获取到对应的网口序号和箱体序号。
通过控制每个显示箱体显示自身对应的可识别图像，以用于后续识别获取对应的网口序号和箱体序号，相对于直接显示网口序号和箱体序号的方案可以降低对采集图像进行解析难度。
在本申请的其他实施例中，前述步骤S12例如包括：对所述采集图像进行识别处理得到所述每个显示箱体对应的网口序号和箱体序号；以及基于所述网口序号和所述箱体序号生成显示箱体的排列信息和连线信息作为所述箱体配置信息。
进一步地，前述提到的对所述采集图像进行识别处理得到所述每个显示箱体对应的网口序号和箱体序号例如包括：根据第一调用函数对所述采集图像进行颜色空间转换得到灰度图像；根据第二调用函数对所述灰度图像进行阈值处理得到处理后图像；根据第三调用函数对所述处理后图像进行轮廓绘制得到所述每个显示箱体对应的箱体图像；根据第四调用函数识别每个箱体图像的图像内容得到所述每个显示箱体对应的所述网口序号和所述箱体序号。
具体地，提到的第一调用函数例如为OpenCV.cvtColor函数。提到的第二调用函数例如为OpenCV.threshold函数。提到的第三调用函数例如为OpenCV.findContours函数。提到的第四调用函数例如为用于图像中文字识别的Tesseract.SetImage函数和Tesseract.Recognize函数、或者为OpenCV中用于识别可识别图像的函数。提到的颜色空间转换例如为将RGB空间转换为灰度空间。提到的阈值处理例如包括去噪和锐化处理，其中去噪处理以及锐化处理的参数可以根据实际场景的光线以及显示箱体对应的箱体图像的色调调节，通过对灰度图像进行阈值处理可以使得灰度图像更加清晰，以便于后续的图像识别。提到的轮廓绘制例如为矩形模式匹配，即识别绘制出显示箱体对应的箱体图像。
将原本需要手动完成的显示屏配置工作通过图像识别实现了自动完成显示屏配置，节省了时间成本及人力成本。
在本申请的其他实施例中，前述步骤S13例如包括：基于所述网口序号和所述箱体序号依次发出分辨率获取指令至所述显示屏控制器，以由所述显示屏控制器基于所 述分辨率获取指令从本地读取预先存储的对应显示箱体的箱体分辨率信息。
前述步骤可以理解为，当获取网口序号和箱体序号后，可以针对每个显示箱体发出分辨率获取指令，显示屏控制器基于接收到的分辨率获取指令从本地存储读取定的显示箱体的箱体分辨率信息。举例而言，显示屏控制器本地存储有显示箱体对应的箱体分辨率信息，收到分辨率获取指令之后，显示屏控制器从本地读取存储的箱体分辨率信息输出。
在本申请的其他实施例中，前述步骤S14例如包括：根据所述排列信息、所述连线信息和所述每个显示箱体对应的所述箱体分辨率信息生成所述每个显示箱体对应的显示坐标；以及将所述每个显示箱体对应的所述显示坐标和所述箱体分辨率信息基于预设文件格式整合得到所述目标配置文件。
具体地，如图2b所示，举例而言，目标显示屏由四个显示箱体组成，每个显示箱体对应的箱体分辨率信息相同，均为64*64，通过前述步骤可以知道显示箱体之间的排序信息和连线信息，两个显示箱体连接显示屏控制器的网口1，两个显示箱体连接显示屏控制器的网口2，获取到箱体分辨率信息后可以计算显示坐标，每个显示箱体的显示坐标例如以左上角为基点，网口1的第一个显示箱体的左上角为坐标原点(0,0)，该坐标(0,0)也为网口1的第一个显示箱体的显示坐标，因为网口1的第二个显示箱体与网口1的第一个显示箱体同行排列，因此网口1的第二个显示箱体对应的显示坐标中纵坐标与网口1的第一个显示箱体的纵坐标相同，横坐标为网口1的第一个显示箱体的横坐标加上第一个显示箱体的宽，因此网口1的第二个显示箱体对应的显示坐标为(64,0)，同理可计算出网口2的第一个显示箱体的显示坐标为(0,64)，网口2的第二个显示坐标为(64,64)，在得到显示坐标和箱体分辨率信息之后，就可以对这些信息进行整合得到目标配置文件，其中提到的预设文件格式例如为目标配置文件所需的模板格式。
为了更好地理解本实施例，下面结合图3对本实施例提出的显示屏配置方法的一种具体实现方式进行举例说明。
当用户选购完LED箱体和显示屏控制器，但是并没有按照安装引导进行LED显示屏的组装时，例如出现LED箱体之间的连线错乱的情况，同样可以使用本实施例公开的显示屏配置方法完成LED显示屏的配置，无需重新拆线连接，操作方便，节省时间。
举例而言，显示屏控制器控制LED显示屏显示如图3所示的指定画面，其中指定画面的内容为每个LED箱体显示x-y，其中x为网口序号，y为该网口串联的箱体序号，即同一网口下的LED箱体按照箱体序号的顺序依次连接，从该指定画面中可以看 出LED显示屏由12块LED箱体拼接而成，且需要显示屏控制器的两个网口进行带载，每个网口下所连接的LED箱体之间的连线错乱。用户例如使用手机对目标显示屏进行拍照，从而使得手机APP获取到采集图像，采集图像与指定画面的内容相同，APP会自动解析采集图像确定箱体配置信息，即可以确定LED箱体的数量为12个，显示屏控制器的网口1连接8个LED箱体，以及显示屏控制器的网口2连接4个LED箱体，以及LED箱体的连线关系。然后手机APP可以接收到显示屏控制器输入的LED显示屏中每个LED显示箱体的箱体分辨率信息，此手机APP接收到箱体分辨率信息后结合箱体配置信息可以生成目标配置文件发送到显示屏控制器中，完成LED显示屏的配置。
需要说明的是，本实施例公开的显示屏配置方法例如实现在应用程序(APP)中，其中应用程序例如为上位机的应用程序，上位机例如为手机或者电脑等用户移动设备，当然本申请并不仅限于此，网页、公众号、或者微信小程序同样可以实现本申请实施例公开的显示屏配置方法。
综上所述，本实施例提出的显示屏配置方法可以无需屏体厂商安排专业工作人员，且无需用户专门学习或者理解LED显示屏相关背景知识，实现普通用户独立完成显示屏配置，避免现有方法需要屏体厂商安排专业工作人员进行配屏的弊端，且当用户需求激增时也能实现用户的独立配屏操作，为屏体厂商节省大量的人力等资源消耗，用户无需等到工作人员便可以自行配置显示屏，节省时间，且操作方便。
