具体实施方式
为了使本申请的技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
在其中一个实施例中，如图1所示，提供了一种显示终端通道切换检测方法，包括以下步骤：
S110：发送遥控码以及遥控码对应的信号源图像至待测显示终端，信号源图像中携带目标通道字符，目标通道字符的显示位置与信号源图像中心彩条位置对应。
遥控码是指通过无线通讯技术对目标进行遥远控制，可以包括蓝牙遥控码、射频遥控码以及红外遥控码等。信号源是指凡是能产生测试信号的仪器，统称为信号源，用于产生被测电路所需特定参数的测试信号。信号源图像包括三色图卡图像、动态显示图像等。待测显示终端可以是电视、电脑、冰箱以及空调等具有显示屏的显示终端，通道包括视屏通道、数字高清通道以及视屏传输通道等。通道字符包括表示显示终端特定通道的通道显示字符，例如显示终端视屏通道中通道字符为“视屏”，数字高清通道(High Definition Multimedia Interface，HDMI)中通道字符为“HDMI”,亚洲电视通道(Asia Television Digital Media Limited，ATV)中通道字符为“ATV”等。在本实施例中，以红外遥控码与三色图卡图像为例，其中，红外遥控是一种无线、非接触控制技术，通过红外线的特定波长的红外光波实现对待测显示终端的远程控制，即通道切换，三色图卡可以为红色、绿色、蓝色三种彩条图卡，图卡可以按照红绿蓝绿蓝的彩条顺序进行排序，预设第三条红色彩条位置为中心位置，且目标通道字符的显示位置可以位于中心彩条上或者中心彩条正上方以及正下方等。可以理解的是，对于遥控码种类和信号源图像中的图卡、图卡中心位置的彩条以及目标通道字符的显示位置与中心彩条位置的对应关系并不限定于一种，可以根据需求进行合理设定。进一步的，遥控码与携带有目标通道字符的信号源图像对应，当遥控码为控制待测显示终端切换为视屏通道的遥控码时，信号源图像为携带目标通道字符为“视屏”的三色图卡图像，且“视屏”目标通道字符的显示位置与图卡图像中心彩条位置对应。非必要的，一个信号源图像中目标通道字符数量可以为多个，例如两个“视屏”或三个“HDMI”等。发送遥控码以及遥控码对应的信号源图像至待测显示终端。通过在信号源图像中加入目标通道字符，对不用不同型号待测显示终端输入统一的信号源，可以保证不同型号的待测显示终端处于相同通道下，其通道字符一致。
S120：采集待测显示终端响应遥控码和信号源图像而显示的通道画面。
检测端发送遥控码以及遥控码对应的信号源图像至待测显示终端后，检测终端根据遥控码以及遥控码对应的信号源图像切换至遥控码对应的通道，显示该通道画面，检测端可以通过摄像头对待测显示终端进行拍照，采集待测显示终端显示的通道画面，例如当检测端发送的遥控码控制切换的通道为视屏通道，信号源图像携带的目标通道字符为“视屏”，待测终端接收遥控码以及信号源图像，根据遥控码和信号源图像，将通道切换为视屏通道，并在显示画面三色图卡中心彩条位置对应的位置显示实际通道字符，通过拍照获取待测终端的通道画面。
S130：对通道画面进行单通道图像处理，追踪单通道中心彩条位置。
图像通道在RGB色彩模式下就是指单独的红色R、绿色G和蓝色B部分，一副完整 的图像，是由红色绿色蓝色三个颜色通道组成。其中，单通道图像处理是将多通道图像分离成几个单通道图像。在本实施例中，将采集到的待测显示终端画面进行单通道处理，例如，当信号源图像中，预设第三条红色彩条位置为图像中心彩条位置时，将红色从多通道图像中分离出来，根据红色灰度值的不同，对红色彩条进行追踪，追踪第三条红色彩条的位置。
S140：根据单通道中心彩条位置，获取实际通道字符。
实际通道字符是指待测终端响应检测端发送的通道切换的遥控码以及信号源图像后将通道切换为与遥控码对应的通道，并根据信号源图像在通道画面显示的通道字符。进一步的，当经过单通道图像处理，追踪到信号源图像图卡的中心彩条位置时，根据中心彩条与目标通道字符对应位置关系，快速寻找到实际通道字符显示位置。具体的，以待测显示终端为电视机为例，当电视机响应数字高清通道切换的遥控码时，将通道切换至数字高清通道，并根据信号源图像中图卡和目标通道字符“HDMI”，显示实际通道字符，当信号源图像中图卡彩条排列顺序为红绿蓝，第四条蓝色彩条预设为中心彩条位置时，目标通道字符显示于中心彩条位置正上方时，获取电视机根据信号源图像和遥控码进行通道切换显示的通道画面，根据单通道图像处理，追踪通道画面中第四条蓝色中心彩条位置，找到显示于蓝色中心彩条位置正上方的实际通道字符。可以理解的是，本实施例中图卡顺序、中心彩条的预设以及目标通道字符的显示位置与中心彩条的对应位置关系不是唯一限定，可以根据需求进行合理设定。目标通道字符出现在与中心彩条对应位置，避免通道字符在待测显示终端边缘位置时，图像采集出现畸变。
S150：根据对目标通道字符与实际通道字符的相似度匹配，进行通道切换检测。
当从待测终端显示的通道画面中获取到实际通道字符时，与信号源图像中的目标通道字符进行比较，通过相似度匹配，对待测显示终端的通道切换功能进行检测。具体的，当实际通道字符与目标通道字符的相似度达到某一程度时，说明待测显示终端根据遥控码与信号源图像进行了对应通道的切换，待测显示终端通道切换功能正常。
上述显示终端通道切换功检测方法，通过发送遥控码以及遥控码对应的信号源图像至待测显示终端，信号源图像中携带目标通道字符，目标通道字符的显示位置与信号源图像中心彩条位置对应；采集待测显示终端响应遥控码和信号源图像而显示的通道画面；对通道画面进行单通道图像处理，追踪单通道中心彩条位置；根据单通道中心彩条位置，获取实际通道字符；根据对目标通道字符与实际通道字符的相似度匹配，进行通道切换检测。整个检测过程中，通过对中心彩条位置的追踪获取位置与中心彩条位置对应的实际通道字符，从而避免采集通道画面过程中造成的图像畸变，且能快速对实际通道字符进行定位，通过对实际通道字符与目标通道字符的相似度匹配进行通道切换检测，不需人工干预，节省检测时间，保证检测结果准确的同时提高了检测效率。
在其中一个实施例中，发送遥控码以及遥控码对应的信号源图像之前还包括：建立通道切换模板；通过通道切换模板，生成待测通道对应的遥控码以及遥控码对应的信号源图 像。其中，通道模板是根据待测显示终端待检测通道以及待检测通道对应的遥控码而建立。进一步的，首先获取待测显示终端的待检测通道，以及待测通道的检测顺序，例如，待检测通道为HDMI1通道、HDMI2通道和ATV通道，根据待测通道生成待测通道对应的HDMI1遥控码、HDMI2遥控码和ATV遥控码，以及各遥控码对应的信号源图像中HDMI1目标通道字符、HDMI2目标通道字符和ATV目标通道字符，以及将目标通道字符的显示位置设置于信号源图像图卡中第三条红色彩条中心彩条位置的正上方。在检测时，根据模板预设通道检测顺序，依次发送对应的通道切换遥控码以及遥控码对应的信号源图像至待检测显示终端。通过事先建立的模板，生成待测通道对应的遥控码以及信号源图像，保证检测结果准确以及检测过程有序进行。
在其中一个实施例中，对通道画面进行单通道图像处理，追踪单通道中心彩条位置包括：调用splid函数对通道画面进行单通道图像处理，追踪单通道中心彩条位置。其中，splid函数是编程语言中使用的一种函数名称，它是指返回一个下标从零开始的一维数组，默认返回一维数组，以指定字符分割。在本实施例中，splid函数用于将一个多通道图像数组分割成几个单通道数组，图像一般是由红绿蓝三个通道组成，通过splid函数，将图像颜色通道进行分离，得到红色单通道图像、绿色单通道图像、蓝色单通道图像，当信号源图像中预设第三条红色彩条位置为中心彩条位置时，通过分离多通道图像，搜寻红色通道，定位第三条红色通道位置。进一步的，根据与中心彩条位置关系对应的目标通道字符显示位置，定位实际通道字符显示位置。能从图像中快速定位中心彩条位置，节省了检测时间，提高了检测效率。
在其中一个实施例中，采集待测终端响应遥控码和信号源图像而显示的通道画面之后，还包括：对通道画面进行去噪处理，获取去噪优化后的通道画面图像。其中，检测端通过调用摄像头等其他摄像设备对待测显示终端的画面进行拍照，获取通道画面时，由于图像采集的环境，如光照明暗程度以及设备性能优劣等原因，往往会存在噪声，该噪声会对之后实际通道字符的处理造成干扰，所以需要先对通道画面进行去噪优化处理。具体的，可以通过高斯滤波、中值滤波、P-M方程以及TV法等方法进行去噪处理。本实施例对于去噪处理的方法并不做限定，可以根据实际需求选择合适的去噪方法。通过对通道画面的去噪处理，可以去除拍摄图像中无关的信息，恢复有用信息，增强图像准确性，从而提高检测效率。
在其中一个实施例中，根据对目标通道字符与实际通道字符的相似度匹配，进行通道切换检测包括：将目标通道字符和实际通道字符进行匹配，当目标通道字符与实际通字符的相似度大于或等于预设阈值时，发送通道切换正常消息。其中，根据从待测显示终端画面中获取的实际通道字符，与信号源图像中的目标通道字符进行对比，进行相似度匹配，当目标通道字符与实际通道字符的相似度达到预设阈值时，说明待测终端根据遥控码切换到了对应的通道，待测显示终端通道切换正常，发送该通道切换功能正常消息至管理终端。进一步的，当遥控为切换ATV通道的遥控码，信号源图像中目标通道字符为“ATV”，当 获取的待测显示终端的实际通道字符为“ATV”时，目标通道字符与实际通道字符的相似度超过预设阈值90％时，此时待测显示终端成功切换ATV通道，发送ATV通道切换成功消息至管理终端，当ATV通道检测成功后，根据通道模板中待测终端通道检测顺序，进行下个通道切换检测。非必要的，检测端可以储存目标通道字符的语音指令信息，当待测显示终端根据对应的遥控码进行通道切换时，将通道画面中显示的实际通道字符以语音方式进行播报，检测端采集待测显示终端的语音信息与目标通道字符的语音指令信息进行相似度匹配，当两者相似度到达预设阈值时，待测终端通道切换正常。可以理解的时，预设阈值可以不仅限于90％，可以根据业务需求进行预设。本实施例中，通过对目标通道字符以及实际通道字符的比较，对通道切换进行检测，避免了人工检测的失误判断，保证了检测结果的准确性。
具体的，在其中一个实施例中，如图2所示，S150还包括：
S151：当实际通道字符与目标通道字符的相似度未达到预设阈值时，重新返回发送遥控码以及遥控码对应的信号源图像的步骤；
S152：当发送遥控码和信号源图像的次数到达预设上限次数时，发送通道切换异常消息。
其中，在进行通道切换检测时，当实际通道字符与目标通道字符的相似度没有到达预设阈值时，检测端重新发送遥控码以及遥控码对应的信号源图像至待测显示终端，重新对待测显示终端的画面进行采集和通道字符的相似度匹配，当相似度仍然未达到预设阈值时，循环此过程，直到检测端发送遥控码以及遥控码对应的信号源图像次数到达预设上限次数时，发送通道切换异常消息至管理终端，非必要的，发送通道切换异常消息的同时并触发警示灯和语音报警提示，将待测显示终端的型号、编号、问题通道等信息显示至LED屏幕，并对检测结果进行记录。可以理解的是，通道切换异常消息可以包括异常通道信息、待测显示终端编号信息、检测时间以及相似度数据等。发送通道切换异常消息后，进入下一通道测试或进入其他项目测试。非必要的，在相似度未达到预设阈值之后的重新检测，可以通过在预设时间内进行检测，当到达预设时间，相似度仍未到达预设阈值时，发送通道切换异常消息。本实施例中，通过对目标通道字符与实际通道字符的多次匹配，防止仪器误检或其他特殊意外情况造成相似度低，保证检测结果的准确。
在其中一个实施例中，目标通道字符包括旋转角度为0度、90度、180度以及270度的字符中至少一种通道字符。其中目标通道字符的设置角度可以包括多种，例如旋转角度为50度、70度、140度等，可以根据具体需求进行设定。进一步的，信号源图像中一个通道图卡中的目标通道字符可以包括多种。例如一个通道图卡中包括0度目标通道字符、90度通道字符、130度通道字符和270度通道字符等。本实施例中，以待测终端为电视机为例，检测电视机视屏通道切换，在一个信号源图像图卡中设置一组目标通道字符，中心彩条位置的正上方设置旋转角度为0度的目标通道字符“视屏”，中心彩条位置正下方设置目标通道字符为旋转180度后的目标通道字符，当电视机无论是以正常观测视角正放， 即旋转角度为0度，还是旋转180度倒放置，在通道切换正常的情况下，都能保证至少有一个实际通道字符能够与目标通道字符匹配，有效防止待测显示终端摆放位置影响目标通道字符与实际通道字符的相似度，造成误检，提高检测效率。

信号发送模块310，用于发送遥控码以及遥控码对应的信号源图像，信号源图像中携带目标通道字符，目标通道字符的显示位置与信号源图像中心彩条位置对应；
