除非另外定义,本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同,而不排除其他元件或者物件。
在现有技术中,主要采用人工检测的方法来对显示面板中的缺陷进行检测,整个检测过程容易漏检、过检,也就是说,现有存在缺陷检测效率低的技术问题。
有鉴于此,本公开实施例提供了一种显示面板的检测方法、装置及系统,用于提高缺陷检测效率,保证显示面板的显示品质。
如图1所示为本公开实施例提供的一种显示面板的检测方法,包括:
S101:获取所述显示面板的包括异形区的待检测图像;
在具体实施过程中,本公开的研究人员发现所述显示面板在玻璃盖板贴 合后的异形区附近是缺陷的集中爆发区域,所述异形区可以是曲面显示面板的弯折区,还可以是在显示面板的显示区开设的用于容置电子器件的透明非显示区,该透明显示区可以是对显示面板进行的通孔设计。在实际应用中,针对所述显示面板的异形区附近,可以是通过一个或多个图像采集单元来采集所述显示面板的包括异形区的图像,相应地,可以获取来自一个或多个图像采集单元的图像,可以是通过一个图像采集单元来采集所述显示面板的包括异形区的图像,相应地,所述待检测图像可以是一个,还可以是通过多个图像采集单元来采集所述显示面板的包括异形区的图像,相应地,所述待检测图像可以是多个。为了保证所获取的所述待检测图像的精度,进而保证图像检测的精度,所述图像采集单元可以是高精度电荷耦合器件(Charge Coupled Device camera,CCD)相机。
S102:从所述待检测图像中计算出油墨区位置坐标;
在具体实施过程中,位于所述油墨区的油墨可以防止所述显示面板边缘漏光,保证所述显示面板的显示品质。
S103:根据所述油墨区坐标位置确定所述待检测图像中的缺陷检测区域;
在具体实施过程,根据所述油墨区坐标位置确定所述待检测图像中的缺陷检测区域,可以将所述待检测图像中除所述油墨区坐标位置之外的区域,作为对所述显示面板进行缺陷检测的区域,这样的话,无需对所述待检测图像中的所有区域进行缺陷检测,只需要对所述待检测图像中除所述油墨区坐标位置之外的缺陷检测区域进行缺陷检测即可,提高了缺陷检测的效率。
S104:通过统计所述缺陷检测区域内的多个像素点的特征信息确定所述待检测图像中的不良缺陷。
在具体实施过程中,通过统计所述缺陷检测区域内的多个像素点的特征信息确定所述待检测图像中的不良缺陷,其中,所述不良缺陷可以是气泡不良,还可以是污渍不良,等等。这样的话,可以直接从所述缺陷检测区域内进行不良缺陷的检测,从而在实现对缺陷自动检测的同时,提高了缺陷检测的效率。
在本公开实施例中,如图2所示,步骤S102:从所述待检测图像中计算出油墨区位置坐标,包括:
S201:对所述待检测图像根据第一阈值进行二值化处理;
S202:根据所述第一阈值二值化处理后的所述待检测图像中的白色像素点的坐标确定所述油墨区坐标位置。
在具体实施过程中,步骤S201至步骤S202的具体实现过程如下:
首先,对所述待检测图像根据第一阈值进行二值化处理,其中,所述第一阈值为预先设置的灰度值,这样的话,经二值化处理后的所述待检测图像中每个坐标位置处的像素点要么为亮点,要么为暗点,由于位于所述油墨区的像素点的灰度值通常比较大,经二值化处理后位于所述油墨区的像素点为白色像素点,如此一来,根据所述第一阈值二值化处理后的所述待检测图像中的白色像素点的坐标便可以确定所述油墨区坐标位置,从而实现了对所述油墨区坐标位置的快速定位。如图3所示为经二值化处理后的所述待检测图像的其中一种示意图,其中,标号C表示所述油墨区,所述油墨区为规则矩形。在实际应用中,所述油墨区还可以是其它形状,在此不做限定。
在本公开实施例中,在步骤S102:从所述待检测图像中计算出油墨区位置坐标之前,所述方法还包括:
对所述待检测图像压缩处理、中值滤波、图像深拷贝处理。
在具体实施过程中,在从所述待检测图像中计算出油墨区位置坐标之前,可以先对所述待检测图像进行图像预处理,所述图像预处理包括压缩处理、中值滤波、图像深拷贝处理。具体地,对所述待检测图像进行压缩处理,所述压缩处理可以是同比例压缩处理,比如,同比例缩小为原来的十六分之一,从而提升了缺陷检测的处理效率。对压缩处理后的图像进一步地进行中值滤波处理,进一步去除图像中的噪声,提高缺陷检测的效率及准确性。对所述待检测图像进行图像深拷贝处理,这样的话,可以根据实际需要对深拷贝处理后的图像中的部分区域进行标示,进一步地保证了缺陷检测的效率。
在本公开实施例中,如图4所示,步骤S202:根据所述第一阈值二值化 处理后的所述待检测图像中的白色像素点的坐标确定所述油墨区坐标位置,包括:
S301:在图像坐标系中,从根据所述第一阈值二值化处理后的所述待检测图像中,获取所述油墨区的纵坐标范围,所述纵坐标范围包括起始纵坐标和终止纵坐标;
S302:计算出所述油墨区在所述起始纵坐标处的第一横坐标数组,在所述终止纵坐标处的第二横坐标数组,以及位于所述起始纵坐标和所述终止纵坐标之间的预设坐标位置处的第三横坐标数组;
S303:根据所述起始纵坐标、所述第一横坐标数组、所述终止纵坐标、所述第二横坐标数组、所述预设坐标位置和所述第三横坐标数组,确定所述油墨区所处的第一横纵坐标范围;
S304:将所述第一横纵坐标范围作为所述油墨区在所述图像坐标系中的坐标位置。
在具体实施过程中,步骤S301至步骤S304的具体实现过程如下:
首先,在图像坐标系中,从根据所述第一阈值二值化处理后的所述待检测图像中确定白色像素点的坐标,所述白色像素点的坐标中第一维为纵坐标,第二维为横坐标,也就是说,确定出所述待检测图像中所有白色像素点的横坐标和纵坐标。然后,根据所述白色像素点的坐标确定所述油墨区坐标位置。具体来讲,在图像坐标系中,从根据所述第一阈值二值化处理后的所述待检测图像中,获取所述油墨区的纵坐标范围,所述纵坐标范围包括起始纵坐标和终止纵坐标,可以是获取所述油墨区背离所述异形区一侧的纵坐标范围,在确定所述纵坐标范围之后,可以确定所述纵坐标范围对应的纵轴,然后,可以确定该纵轴预设坐标位置处的纵坐标,进一步地确定该预设坐标位置处的纵坐标对应的所有白色像素点的横坐标,其中,该预设坐标位置处的纵坐标对应的所有白色像素点的横坐标对应的像素点个数可以是大于5。然后,确定该预设坐标位置处的纵坐标对应的所有白色像素点的横坐标的数值中的最小横坐标、中间横坐标和最大横坐标,然后,根据所述最小横坐标、中间横 坐标和最大横坐标确定所述预设坐标位置处的第三横坐标数组,然后,根据所述第三横坐标数组确定所述油墨区的起始纵坐标和在所述起始纵坐标处的第一横坐标数组,以及在所述终止纵坐标处的第二横坐标数组和在所述终止纵坐标处的第二横坐标数组,进而确定出所述油墨区所处的第一横纵坐标范围,然后,将所述第一横纵坐标范围作为所述油墨区在所述图像坐标系中的坐标位置,从而实现了对所述油墨区在所述待检测图像中的定位。
仍以图3所示的所述待检测图像为例来说明,所述油墨区C背离所述异形区的一侧如图5中的虚线aa’所示,所述纵坐标范围可以为[y0,y],所述起始纵坐标可以为y0,所述终止纵坐标可以为y。然后,计算出所述油墨区在所述起始纵坐标处的第一横坐标数组,所述油墨区在所述终止纵坐标处的第二横坐标数组,所述第一横坐标数组可以表征所述油墨区在所述起始纵坐标处的横坐标范围,所述第二横坐标数组可以表征所述油墨区在所述终止纵坐标处的横坐标范围。此外,还计算出位于所述起始纵坐标和所述终止纵坐标之间的预设坐标位置处的第三横坐标数组,所述第三横坐标数组可以表征所述油墨区在所述纵坐标范围的预设坐标位置处的横坐标范围。在具体实施过程中,所述预设坐标位置可以是所述纵坐标范围的三分之一处的位置,如图5中所述预设坐标位置(标号Y所示)为所述纵坐标范围的三分之一处的位置,还可以是所述纵坐标范围的二分之一处的位置,本领域技术人员可以根据实际应用需要来选择所述预设坐标位置,在此不做限定。然后,根据所述起始纵坐标、所述第一横坐标数组、所述终止纵坐标、所述第二横坐标数组、所述预设坐标位置和所述第三横坐标数组,确定所述油墨区所处的第一横纵坐标范围,并将所述第一横纵坐标范围作为所述油墨区在所述图像坐标系中的坐标位置,从而实现了对所述油墨区在图像坐标系中的定位。
在本公开实施例中,如图6所示,在步骤S102:从所述待检测图像中计算出油墨区位置坐标之后,所述方法还包括:
S401:对所述待检测图像根据第二阈值进行二值化处理;
S402:根据所述第二阈值二值化处理后的所述待检测图像中的白色像素 点的坐标和所述油墨区坐标位置确定反光区域的位置坐标;
相应地,步骤S103:根据所述油墨区坐标位置确定所述待检测图像中的缺陷检测区域,包括:
根据所述油墨区坐标位置和所述反光区域的位置坐标确定所述待检测图像中的缺陷检测区域。
在具体实施过程中,步骤S401至步骤S402的具体实现过程如下:
在从所述待检测图像中计算出油墨区位置坐标之后,对所述待检测图像根据所述第二阈值进行二值化处理,其中,所述第二阈值为预先设置的灰度值,所述第二阈值与所述第一阈值可以是同一灰度值,还可以是不同的灰度值,在此不做限定。经所述第二阈值进行二值化处理后所述待检测图像中每个像素点要么为亮点,要么为暗点,在实际应用中,本公开的研究人员发现,用于承载所述显示面板的载台通常由金属材料制成,在所述图像采集单元采集所述待检测图像的过程中,所述待检测图像中往往还存在大面积的反光区域。具体地,根据所述第二阈值二值化处理后的所述待检测图像中的白色像素点的坐标和所述油墨区坐标位置确定反光区域的位置坐标。在确定出所述反光区域的位置坐标之后,根据所述油墨区坐标位置和所述反光区域的位置坐标确定所述待检测图像中的缺陷检测区域,如此一来,在对所述显示面板进行缺陷检测之前,可以先排除所述油墨区和所述反光区域对缺陷检测的干扰,然后,再确定出所述待检测图像中的缺陷检测区域,从而提高了缺陷检测的效率。
在本公开实施例中,如图7所示,步骤S402:根据所述第二阈值二值化处理后的所述待检测图像中的白色像素点的坐标和所述油墨区坐标位置确定反光区域的位置坐标,包括:
S501:从根据所述第二阈值二值化处理后的所述待检测图像中的白色像素点的坐标中除所述油墨区坐标位置外,计算出位于同一连通域中同时满足纵坐标小于所述起始纵坐标且大于第一预设个数的多个像素点;
S502:确定所述连通域在所述图像坐标系中的第二横纵坐标范围;
S503:将所述第二横纵坐标范围作为反光区域在所述图像坐标系中的坐标位置。
在具体实施过程中,步骤S501至步骤S503的具体实现过程如下:
首先,从根据所述第二阈值二值化处理后的所述待检测图像中的白色像素点的坐标中除所述油墨区坐标位置外,计算出位于同一连通域中同时满足纵坐标小于所述起始纵坐标且大于第一预设个数的多个像素点,所述第一预设个数可以为本领域技术人员根据实际应用需要所设定的个数,比如,所述第一预设个数为400,其中,所述多个像素点为灰度值大于预设值的亮点。然后,确定所述连通域在所述图像坐标系中的第二横纵坐标范围,并将所述第二横纵坐标范围作为所述反光区域在所述图像坐标系中的坐标位置,所述反光区域在所述待检测图像中的坐标位置可以是如图5中标号D所示的位置。如此一来,便实现了对所述反光区域的快速定位。
在本公开实施例中,如图8所示,步骤S104:通过统计所述缺陷检测区域内的多个像素点的特征信息确定所述待检测图像中的不良缺陷,包括:
S601:重新获取所述待检测图像,并对所述待检测图像依次进行灰度化处理、中值滤波处理、同比例缩小处理和根据第三阈值进行二值化处理;
S602:通过统计根据所述第三阈值进行二值化处理后的所述缺陷检测区域内的多个像素点的特征信息确定所述待检测图像中的不良缺陷。
在具体实施过程中,步骤S601至步骤S602的具体实现过程如下:
在根据所述油墨区坐标位置确定所述待检测图像中的缺陷检测区域之后,重新获取所述待检测图像,并对所述待检测图像进行灰度化处理,获得灰度化处理后的图像,比如,可以是以灰度模式重新读取所述待检测图像,然后对灰度化处理后的图像进行中值滤波处理,获得滤波后的图像,然后,再将滤波后的图像进行同比例缩小处理,获得缩小后的图像,然后,再将所述缩小后的图像根据第三阈值进行二值化处理,获得黑白图像,其中,所述第三阈值为预先设置的灰度值,通过统计根据所述第三阈值进行二值化处理后的所述缺陷检测区域内的多个像素点的特征信息确定所述待检测图像中的不良 缺陷。在具体实施过程中,通过重新获取所述待检测图像来进行不良缺陷检测避免了细节的缺失,提高了检测的准确率。此外,对所述待检测图像依次进行灰度化处理、中值滤波处理、同比例缩小处理提高了缺陷检测的效率,根据所述第三阈值进行二值化处理实现了缺陷不良的检测。
在本公开实施例中,如图9所示,步骤S602:通过统计根据所述第三阈值进行二值化处理后的所述缺陷检测区域内的多个像素点的特征信息确定所述待检测图像中的不良缺陷,包括:
S701:从根据所述第三阈值进行二值化处理后的所述缺陷检测区域内的多个像素点中统计出至少一个像素点集合,所述像素点集合中的像素点的灰度值相同且位于同一个连通域;
S702:计算各个所述像素点集合中的像素点个数;
S703:将像素点个数大于第二预设个数的所述像素点集合所在的连通域作为所述待检测图像中的不良缺陷区域。
在具体实施过程中,步骤S701至步骤S703的具体实现过程如下:
首先,从根据所述第三阈值进行二值化处理后的所述缺陷检测区域内的多个像素点中统计出至少一个像素点集合,所述像素点集合中的像素点的灰度值相同且位于同一个连通域,每个所述像素点集合中的像素点为亮点,其中,所述连通域的具体确定过程为,从根据所述第三阈值进行二值化处理后的所述缺陷检测区域内确定出每个白色像素点的坐标位置,若相邻两白色像素点的坐标位置之间的距离小于预设距离阈值,所述预设距离阈值为根据实际应用需要所设置的数值,则说明该相邻两白色像素点位于同一连通域,其中,每个白色像素点的灰度值均为同一灰度值。然后,计算各个所述像素点集合中的像素点个数,将像素点个数大于第二预设个数的所述像素点集合所在的连通域作为所述待检测图像中的不良缺陷区域。其中,所述第二预设个数为预先设置的个数,比如,所述第二预设个数为200,比如,像素点个数大于所述第二预设个数的所述像素点集合所在的连通域可以是如图5中标号E所示的区域,这样的话,便实现了对缺陷检测区域内不良缺陷的检测,无需 对所述待检测区域内的所有区域进行检测,提高了缺陷检测的效率。
在本公开实施例中,在步骤S703:将像素点个数大于第二预设个数的所述像素点集合所在的连通域作为所述待检测图像中的不良缺陷区域之后,所述方法还包括:
对所述像素点集合所在的连通域进行标示,以提示所述显示面板与所述待检测图像中的不良缺陷区域对应位置存在不良缺陷。
在具体实施过程中,在将像素点个数大于所述第二预设个数的所述像素点集合所在的连通域作为所述待测图像中的不良缺陷区域之后,对所述像素点集合所在的连通域进行标示,比如,采用OPEN CV计算机视觉库对所述不良缺陷区域进行画圈标示,所画的圈可以是圆形,还可以是椭圆形,在此不做限定,如此一来,便可以提示用户所述显示面板与所述待检测图像中的不良缺陷区域对应位置存在不良缺陷,比如,气泡。此外,在具体实施过程中,还可以采用除画圈外的其它方式来对所述不良缺陷区域进行标示,在此不做限定。此外,还可以将标示后的结果写入所述待检测图像对应的图片文件中,以便用户可以随时进行查看,从而提高了用户的使用体验。
在本公开实施例中,如图10所示,在步骤S201:对所述待检测图像根据第一阈值进行二值化处理之前,所述方法还包括:
S801:对所述待检测图像进行同比例缩小处理,获得缩小后的图像;
S802:将所述缩小后的图像进行中值滤波处理,获得滤波后的图像,将所述滤波后的图像作为所述待检测图像。
在具体实施过程中,步骤S801至步骤S802的具体实现过程如下:
在对所述待检测图像根据第一阈值进行二值化处理之前,可以先对所述待检测图像进行同比例缩小处理,比如,同比例缩小为原来的十六分之一,获得缩小后的图像,从而提高缺陷检测的效率。还可以,再将所述缩小后的图像进行中值滤波处理,获得滤波后的图像,从而去除了所述待检测图像中的噪声,然后,将所述缩小后的图像作为所述待检测图像,也就是说,在对所述待检测图像进行二值化处理之前,可以对所述待检测图像依次进行同比 例缩小、中值滤波等预处理,从而提高了后续对所述待检测图像的缺陷检测速率。
