Description

显示界面切换功能的检测方法及系统Method and system for detecting display interface switching function 技术领域Technical field
本发明涉及显示设备技术领域，尤其涉及一种显示界面切换功能的检测方法及系统。The present invention relates to the technical field of display devices, and in particular to a method and system for detecting display interface switching functions.
背景技术Background technique
在显示器的生产过程中，特别是电视机的生产过程中，对显示通道或显示频道切换功能的检测是一个需要多次确认的工序。显示通道或显示频道切换功能指的都是用户可以通过遥控器与电视机进行人机交互，根据个人喜好把电视机切换到任意显示通道或显示频道。若电视机的显示通道或显示频道切换不灵敏，则会导致用户无法切换到想要的显示通道或显示频道，如此则该电视机不是合格品，需要进行返修。In the production process of the display, especially the production process of the TV, the detection of the display channel or the display channel switching function is a process that requires multiple confirmations. The display channel or display channel switching function means that the user can interact with the TV through the remote control and switch the TV to any display channel or display channel according to personal preference. If the display channel or display channel of the TV is not sensitively switched, the user cannot switch to the desired display channel or display channel. In this case, the TV is not a qualified product and needs to be repaired.
现有的电视机生产商对显示通道或显示频道切换检测方面普遍是由产线上的检测人员控制遥控器将电视机切换到待检测的显示通道或显示频道上，并由人工判断电视机的显示通道或显示频道是否切换成功。以电视机的显示通道切换为例，具体的，现有电视机的显示通道的切换过程，是通过识别显示通道对应的通道字符来判断显示通道的切换是否成功。但是由于不同型号、不同尺寸大小的电视机所对应的通道字符的字体和字号都有可能不同，因此会提高判断切换是否成功的错误率。Existing TV manufacturers generally use the inspection personnel on the production line to control the remote control to switch the TV to the display channel or display channel to be tested in the display channel or display channel switching detection, and manually judge the TV Whether the display channel or display channel is switched successfully. Taking the display channel switching of a TV as an example, specifically, the switching process of the display channel of an existing TV set determines whether the switching of the display channel is successful by identifying the channel character corresponding to the display channel. However, since the fonts and font sizes of the channel characters corresponding to different models and sizes of TV sets may be different, the error rate of judging whether the switching is successful will be increased.
同时，依据现有的电视机生产商对显示通道或显示频道切换检测方法，完整检测一台电视机的全部通道或频道往往需要很多检测人员，如此提高了电视机的生产成本，且人工检测效率低并容易出现误检情况，对后续的自动化检测会造成不利的影响。At the same time, according to the existing TV manufacturer's detection method for display channel or display channel switching, the complete detection of all channels or channels of a TV often requires a lot of inspection personnel, which increases the production cost of the TV and the efficiency of manual detection It is low and prone to misdetection, which will adversely affect subsequent automated detection.
发明内容Summary of the invention

In addition, the detection method and system determine whether the display interface switching function of the display device is normal according to the arrangement order of the color patches in the target color group and the preset contrast color group, so that the detection method And the system is suitable for the detection of channels or/and channel switching functions of TVs of various models and sizes.

In addition, the detection method judges whether the display interface switching function of the display device is normal according to the arrangement order of the color patches in the target color group and the preset contrast color group, which can make the detection method suitable for Detection of channel switching function of various models and sizes of TV sets.
在一种可选的实施例中，所述预设的对照色组包括至少两种不同的色块，不同的预设的对照色组中色块的排列顺序不同。In an optional embodiment, the preset contrast color group includes at least two different color blocks, and the order of the color blocks in the different preset contrast color groups is different.
在一种可选的实施例中，所述预设的对照色组包括至少两种不同颜色的色块。In an optional embodiment, the preset contrast color group includes at least two color blocks of different colors.
具体的，在构建所述预设的对照色组的过程中，即在确定每个通道对应的预设的对照色组的过程中，以相同大小且形状均为矩形的红色色块、蓝色色块和绿色色块构建每个通道对应的预设的对照色组，例如，构建HDMI1通道对应的预设的对照色组中色块的排列顺序为红绿蓝绿蓝，也可表示为RGBGB；构建HDMI2通道对应的预设的对照色组中色块的排列顺序为蓝绿蓝绿红，也可表示为BGBGR。Specifically, in the process of constructing the preset control color group, that is, in the process of determining the preset control color group corresponding to each channel, red color blocks and blue color blocks of the same size and rectangular shapes are used. Blocks and green color blocks construct a preset contrast color group corresponding to each channel. For example, the arrangement order of color blocks in the preset contrast color group corresponding to the HDMI1 channel is red, green, blue, green and blue, which can also be expressed as RGBGB; The arrangement order of the color blocks in the preset control color group corresponding to the HDMI2 channel is blue, green, blue, green and red, which can also be expressed as BGBGR.
在一种可选的实施例中，所述目标色组包括至少两种不同颜色的色块。In an optional embodiment, the target color group includes at least two color blocks of different colors.
所述获取所述目标色组和预设的对照色组，包括：The obtaining the target color group and the preset contrast color group includes:
获取所述目标色组中色块的排列顺序和所述预设的对照色组中色块的排列顺序。The arrangement order of the color blocks in the target color group and the arrangement order of the color blocks in the preset contrast color group are acquired.

根据所述目标色组中色块的排列顺序和所述预设的对照色组中色块的排列顺序，判断所述目标色组中色块的排列顺序与所述预设的对照色组中色块的排列顺序是否匹配，若是，则判定所述显示设备的显示界面切换功能正常，若否，则判定所述显示设备的显示界面切换功能不正常。According to the arrangement order of the color blocks in the target color group and the arrangement order of the color blocks in the preset comparison color group, it is determined that the arrangement order of the color blocks in the target color group is different from that in the preset comparison color group. Whether the arrangement sequence of the color blocks matches, if it is, it is determined that the display interface switching function of the display device is normal, and if not, it is determined that the display interface switching function of the display device is abnormal.
在显示设备根据HDMI2通道的切换指令，由HDMI1通道切换至HDMI2 通道后，从所述显示设备的显示界面获取的目标色组仍为与HDMI1通道对应的对照色组：RGBGB，而并不是与HDMI2通道对应的对照色组：BGBGR。由此可以确定所述显示设备的HDMI2通道切换功能不正常。After the display device switches from the HDMI1 channel to the HDMI2 channel according to the HDMI2 channel switching instruction, the target color group obtained from the display interface of the display device is still the control color group corresponding to the HDMI1 channel: RGBGB, not the HDMI2 channel. The control color group corresponding to the channel: BGBGR. Therefore, it can be determined that the HDMI2 channel switching function of the display device is abnormal.
但若所述目标色组是在所述显示设备倒立放置的情况下获取的，则在获取的目标色组可能与HDMI2通道对应的对照色组完全颠倒的情况下，即获取的HDMI2通道对应的目标色组为RGBGB，仍可确定所述显示设备的HDMI2通道切换功能正常。However, if the target color group is acquired when the display device is placed upside down, the acquired target color group may be completely reversed from the control color group corresponding to the HDMI2 channel, that is, the acquired HDMI2 channel corresponds to The target color group is RGBGB, and it can still be determined that the HDMI2 channel switching function of the display device is normal.

其中，所述获取所述预设的对照色组中色块的排列顺序的步骤，包括：根据切换指令，确定显示设备将要切换至的通道，并将该通道作为目标通道。根据所述目标通道，确定与所述目标通道对应的预设的对照色组。Wherein, the step of obtaining the sequence of the color blocks in the preset comparison color group includes: determining the channel to which the display device is to be switched according to the switching instruction, and using the channel as the target channel. According to the target channel, a preset contrast color group corresponding to the target channel is determined.
对于不同品牌不同型号大小的显示设备，特别是电视机能够适用同一个通道RGB彩条排序库进行判断，进一步减少了人工干预，并提高了自动化程度。For display devices of different brands and sizes, especially TV sets, the same channel RGB color bar sorting library can be used for judgment, which further reduces manual intervention and improves the degree of automation.
在一种可选的实施例中，所述获取所述目标色组中色块的排列顺序，包括：In an optional embodiment, the acquiring the sequence of the color blocks in the target color group includes:
根据所述目标色组中色块的颜色，确定所述目标色组中色块在所述显示界面的位置。According to the color of the color block in the target color group, determine the position of the color block in the target color group on the display interface.
根据所述目标色组中色块在所述显示界面的位置，获取所述标色组中色块的排列顺序。According to the position of the color blocks in the target color group on the display interface, the arrangement order of the color blocks in the target color group is acquired.
具体的，所述获取所述目标色组中色块的排列顺序的步骤，包括：在通过彩色相机对显示设备的显示界面进行图像采集后，依次进行RGB通道分解算法，阈值分割算法以及BLOB分析算法。上述三种算法容错性强，对产线环境要求低，不受现场光线亮暗、噪声强弱的影响，在一般的产线上就能够得到应用。Specifically, the step of acquiring the arrangement order of the color blocks in the target color group includes: after performing image acquisition on the display interface of the display device through a color camera, sequentially performing an RGB channel decomposition algorithm, a threshold segmentation algorithm, and a BLOB analysis algorithm. The above three algorithms are highly fault-tolerant, have low requirements on the production line environment, and are not affected by the intensity of the light or noise on the spot, and can be applied in general production lines.
其中，由于采用彩色相机对显示界面进行拍照，获取的彩色图像中包含红、绿、蓝三个灰色通道，利用RGB通道分解算法可以将显示界面所显示的彩色图像分为红色通道下的图像、绿色通道下的图像、蓝色通道下的图像，其中每个通道都是0-255的灰度值组成。例如，红色彩条的灰度值为[255，0，0]，则红色矩形在红色通道下表现为灰度值为255的彩条，而绿色矩形和蓝色矩形在红色通道下表现为灰度值均为接近于0的彩条。Among them, because the color camera is used to take pictures of the display interface, the acquired color image contains three gray channels of red, green, and blue. Using the RGB channel decomposition algorithm, the color image displayed on the display interface can be divided into images under the red channel, The image under the green channel and the image under the blue channel, where each channel is composed of a gray value of 0-255. For example, if the gray value of the red color bar is [255, 0, 0], the red rectangle is represented as a color bar with a gray value of 255 in the red channel, and the green and blue rectangles are represented as gray in the red channel. The degree values are all color bars close to 0.
而阈值分割算法的目的是要按照灰度级，对像素集合进行一个划分，得到的每个子集形成一个与现实景物相对应的区域，各个区域内部具有一致的属性，而相邻区域不具有这种一致属性。如在红色通道选取灰度值为[200，255]的点的集合，如此则可以把彩色图像中所有红色彩条的区域按照原来矩形的大小被分割出来。The purpose of the threshold segmentation algorithm is to divide the pixel set according to the gray level, and each obtained subset forms an area corresponding to the real scene. Each area has the same attributes, while the adjacent areas do not have this. A consistent attribute. If a set of points with a gray value of [200, 255] is selected in the red channel, then all the areas of the red color bars in the color image can be segmented according to the size of the original rectangle.
BLOB分析算法是对经阈值分割算法处理后的图像中相同或相近灰度值的连通域进行分析，其中该连通域称为Blob。经二值化(Binary Thresholding)处理后的图像中的色斑，所述色斑即拍摄时由周围环境产生的白色色块。Blob 分析算法可以精准的从含有背景的图像中将显示界面分离出出来，并计算出相同颜色的色块的数量、位置、形状、方向和大小等。通过最终获得的不同颜色色块在显示界面的位置，即可确定目标色组中色块的排列顺序。The BLOB analysis algorithm analyzes the connected domains of the same or similar gray value in the image processed by the threshold segmentation algorithm. The connected domain is called Blob. Color spots in an image processed by Binary Thresholding, the color spots are white patches generated by the surrounding environment during shooting. The Blob analysis algorithm can accurately separate the display interface from the image containing the background, and calculate the number, position, shape, direction and size of the color patches of the same color. The position of the color blocks of different colors finally obtained on the display interface can determine the order of the color blocks in the target color group.
在一种可选的实施例中，在通过彩色相机对显示设备的显示界面进行图像采集后，将采集到的彩色图像先进行RGB通道分解算法，对于包含红色、蓝色和绿色色块的彩色图像来说，其本身包含有红色、绿色和蓝色三个通道，彩色图像上的每一个点的灰度值的格式可以表示为(a，b，c)，其中a代表的是该像素点在红色通道的灰度值，b代表的是该像素点在绿色通道的灰度值，c代表的是该像素点在蓝色通道的灰度值。In an optional embodiment, after the image is captured on the display interface of the display device through the color camera, the captured color image is first subjected to the RGB channel decomposition algorithm. For the color including red, blue, and green color blocks, The image itself contains three channels of red, green and blue. The format of the gray value of each point on the color image can be expressed as (a, b, c), where a represents the pixel point In the gray value of the red channel, b represents the gray value of the pixel in the green channel, and c represents the gray value of the pixel in the blue channel.
因此，采集到的彩色图像所有像素点在红色通道下的集合组成一幅新的图像，即红色通道下的图像，而绿色通道下的图形和蓝色通道下的图像以此类推。Therefore, the collection of all the pixels of the collected color image under the red channel constitutes a new image, that is, the image under the red channel, and the graph under the green channel and the image under the blue channel are analogized by analogy.
对于彩条图像来说，红色的像素点的灰度值为(255，0，0)，绿色的像素点的灰度值为(0，255，0)，蓝色的像素点的灰度值为(0，0，255)。For the color bar image, the gray value of the red pixel is (255, 0, 0), the gray value of the green pixel is (0, 255, 0), and the gray value of the blue pixel Is (0, 0, 255).
采集到的彩色图像中的白色区域，即色斑的像素点的灰度值为(255，255，255)，黑色区域的像素点的灰度值为(0，0，0)。The gray value of the white area in the collected color image, that is, the pixel point of the color spot is (255,255,255), and the gray value of the pixel point of the black area is (0,0,0).
因此，首先，对采集到的彩色图像进行通道分解成三个通道下的图像，即红色通道下的图像、绿色通道下的图形和蓝色通道下的图像。选取红色通道下的图像，由于红色通道下的图像里面的红色彩条的灰度值在红色通道下的图像相应区域均为255，即红色彩条表现为一块由灰度值为255的像素点的集合。Therefore, first, the collected color image is channel-decomposed into images under three channels, namely, the image under the red channel, the graph under the green channel, and the image under the blue channel. Select the image under the red channel, because the gray value of the red color bar in the image under the red channel is 255 in the corresponding area of the image under the red channel, that is, the red color bar is represented by a pixel with a gray value of 255 Collection.
然后，利用阈值分割算法选取给定灰度值的区域，即选取红色通道下的图像的像素点的灰度值为255的区域，则可以把红色彩条和采集到的彩色图像中有白色区域的地方选取出来。Then, use the threshold segmentation algorithm to select the area of the given gray value, that is, select the area where the gray value of the pixel of the image under the red channel is 255, then the red color bar and the white area in the collected color image can be selected Select the place.
由于在彩条图像中不同颜色的色块都是标准的矩形，则利用BLOB通道 分析算法，即可选取当前所有的矩形度大于0.9的区域作为所求的区域，从而筛掉白色区域，从而获取到所有红色的矩形色块及相关位置信息。其中获取绿色的矩形色块及相关位置信息和获取蓝色的矩形色块及相关位置信息，与获取红色的矩形色块及相关位置信息相同，在此不做赘述。Since the color blocks of different colors in the color bar image are all standard rectangles, the BLOB channel analysis algorithm can be used to select all the current areas with a rectangle degree greater than 0.9 as the desired area, so as to filter out the white area and obtain To all the red rectangular color blocks and related position information. Obtaining the green rectangular color block and related position information and obtaining the blue rectangular color block and related position information are the same as obtaining the red rectangular color block and related position information, and will not be repeated here.
