Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of edge inspection, and more particularly to an image enhancement method and device, a positioning method and device, an edge inspection method and device, and a storage medium. BACKGROUND

[0002] The edge inspection device is mainly used for detecting whether the edge regions of four edges of a display panel formed by bonding a color film substrate CF and an array substrate TFT exist defects, such as cracks, shells, broken pieces and burrs, after cutting or grinding. The purpose is to remove the display panel with defects or larger defects for the next process. The edge inspection device usually includes a visual processing system, which includes a shooting module and a processing module. The shooting module is mainly used for shooting a photo of the edge region and sending it to the processing module. The processing module is mainly used for edge recognition and cutting accuracy determination for the photo sent by the shooting module.

[0003] Generally, the area of the CF substrate is smaller than that of the TFT substrate, and the mark point is arranged on the TFT substrate. The cutting accuracy is generally represented by the difference between the actual vertical distance between the outer edge of one side of the TFT substrate and the mark on the side and the theoretical vertical distance. As can be seen, the cutting accuracy is strongly related to the mark point. However, the mark point is only arranged on one side of the TFT substrate with a stepped surface, and no mark point is designed on the other side, which brings difficulties to obtain the cutting accuracy of each side.

[0049] In order to make the objects, technical solutions and advantages of the present application more obvious, the following will describe the example embodiments according to the present application with reference to the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application, and it should be understood that the present application is not limited to the example embodiments described herein. Based on the embodiments of the present application described in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present application.

[0050] In order to at least partially solve the above technical problems, the embodiments of the present application provide a virtual marker position determination method, as shown in Figure 1 The method comprises the following steps:

[0051] S1 receiving step: receiving a first image of a panel edge region having two first real markers, and receiving a second image of a panel edge region having one second real marker.

[0052] S2 connecting line determination step: determining a first connecting line of the two first real markers in the first image;

[0053] S3 virtual marker determination step: determining the position of the virtual marker in the coordinate system of the first image and the second image according to the second real marker in the second image, the first connecting line, a preset relationship between the first connecting line and a second connecting line, and a preset distance between the second real marker and the virtual marker to be determined; the second connecting line is a connecting line between the second real marker and the virtual marker.

[0054] In the present embodiment, the method further comprises:

[0055] Image acquisition steps: The image acquisition module moves along the first direction to capture the edge area of ​​the imaging panel to obtain a first image of the edge area on one side of the panel and a second image of the edge area on the other side of the rotated panel.

[0056] like Figure 2 As shown, the edge region of the first side of the panel includes: a first real marker point mark1 and a second real marker point mark2; in the image acquisition step, specifically, the image acquisition module moves along a first direction to capture the edge region of the first side of the panel to obtain a first image 10, the first image including the first real marker point mark1 and the second real marker point mark2; and moves back and forth along the first direction to capture the edge regions of the second and third sides of the rotated panel to obtain two second images accordingly, wherein, specifically, the panel is rotated 90 degrees clockwise to obtain a second image 20 including the second real marker point mark2; the panel is rotated 90 degrees counterclockwise to obtain a second image 21 including the first real marker point mark1; wherein, the second side and the third side are adjacent to the first side; in the virtual marker point determination step S3, specifically, two virtual marker points are determined one-to-one according to the two second images, virtual marker point mark2' is determined according to the second image 20, and virtual marker point mark1' is determined according to the second image 20.

[0057] In Figure 2 In this diagram, the first direction is horizontal (as shown by the dotted line). The image acquisition module can move from the initial position on the left to the position on the right, and then return to the initial position to move from left to right for the next shot. Alternatively, it can move directly from right to left to capture the rotated panel without returning to the initial position. Since both the first and second images are acquired by the image acquisition device, the coordinate system of the first and second images in step S3 is based on the coordinate system established by the images captured by the image acquisition device, and the determined virtual marker points are also located in this coordinate system. Furthermore, in this scenario, the preset relationship between the first and second connecting lines is parallel. Since the marker point "mark" refers to the cutting marker point, the distance between the real marker point "mark" and the virtual marker point "mark'" is artificially set, i.e., known.

[0058] Therefore, in this embodiment, based on the parallel relationship between the first and second connecting lines, the position of the second real marker point, and the distance, a virtual marker point "mark'" can be determined at a position on the second connecting line at a distance from the second real marker point. In practical applications, the distances between the real and virtual marker points and the edge lines of the edge region on that side of the panel can be calculated based on the coordinates of the virtual marker point "mark'" and the edge lines identified on that side of the panel, thus obtaining the panel cutting accuracy.

[0059] In the embodiment, as shown in Figure 2 the display panel includes a TFT substrate and a CF substrate, one edge of the TFT substrate protrudes the CF substrate, the first real mark point mark1 and the second real mark point mark2 are formed on the protruding step, and since an electrode is formed on the protruding step, it is called a "single-electrode panel". In comparison Figure 2 , Figure 3 the panel TFT substrate has two edges protruding the CF substrate, and electrodes are arranged on the two protruding step surfaces, so it is called a "double-electrode panel".

[0060] Specifically, the edge region of the first side of the panel includes the first real mark point mark1, the edge region of the second side adjacent to the first side of the panel includes the third real mark point mark3, and the overlapping edge region of the first side and the second side of the panel further includes the second real mark point mark2. In the case of a double-electrode panel, the image acquisition step specifically includes: the image acquisition module reciprocally moves along the first direction to shoot the edge region of the first side of the panel to acquire a first image, and the first image includes the first real mark point mark1 and the second real mark point mark2; and reciprocally moves along the first direction to shoot the edge region of the third side of the panel after rotation to acquire a second image, wherein the third side is adjacent to the first side, and the second image including the first real mark point mark1 can be acquired from the edge region of the third side of the panel after rotating 90° counterclockwise. According to the second image, the virtual mark point mark1' corresponding to the first real mark point mark1 can be determined.

[0061] It should be noted that the above description is a scheme for determining the virtual mark point in the case of a single-electrode panel and a double-electrode panel by using only one image acquisition module, but in actual application, it is not limited thereto, and two or more image acquisition modules can also be used, and the multiple image acquisition modules reciprocally move along different directions to shoot the edge regions of different sides of the panel, for example, two image acquisition modules reciprocally move along the horizontal direction to shoot the edge regions of two opposite sides of the panel, and each image acquisition module can acquire a first image and a second image, the coordinate system of the first image and the second image is a coordinate system established based on the shooting image of the corresponding image acquisition module, the coordinate systems of different image acquisition devices are independent of each other, and the virtual mark points determined by each are on the corresponding coordinate system. It can be understood that by using multiple image acquisition devices to determine the virtual mark point, the edge regions of different sides of the panel can also be shot at the same time, that is, the edge regions of different sides are identified at the same time, so that compared with only one image acquisition device, the cutting precision detection of the four edges of the panel can be quickly completed.

[0062] It should be noted that in the image acquisition step described above, each image acquisition module acquires a respective first image and a second image, but in actual applications, the image acquisition step can also include: the first image acquisition module moves the edge region of the shooting panel along the first direction to acquire the first image, and the second image acquisition module moves the edge region of the shooting panel along the second direction to acquire the second image.

[0063] In this case, the coordinate system in which the first image and the second image are located is a coordinate system established based on the shooting images of the first image acquisition module and the second image acquisition module; if the first direction is the horizontal direction on the paper and the second direction is the vertical direction on the paper, then the preset relationship between the first connecting line and the second connecting line is a vertical relationship; then, according to the vertical relationship between the first connecting line and the second connecting line, the position of the second real marker point, and the distance, the position of the virtual marker point mark on the second connecting line perpendicular to the first connecting line and at a distance of the distance from the second real marker point can be determined.

[0064] In another embodiment, the first direction and the second direction are parallel; the second image acquisition module and the first image acquisition module can simultaneously move along the edge regions of the opposite sides of the panel, respectively. In the case of a single-electrode panel, as shown in FIG. 2B, the edge region of only the first side of the panel includes the first real marker point mark1 and the second real marker point mark2; in the image acquisition step, specifically including: the first image acquisition module moves the edge region of the first side of the shooting panel along the first direction to acquire the first image; the first image acquisition module and the second image acquisition module move along the edge regions of the second side and the third side of the rotated panel to acquire two second images, respectively; wherein the second side and the third side are adjacent to the first side, and the second side and the third side are opposite; in the virtual marker point determination step, specifically including: two virtual marker points are determined according to the two second images. Figure 4

[0065] More specifically, at the first time point: the first and second image acquisition modules move from left to right while shooting the edge regions of the first side and the fourth side, and the first image acquisition module acquires the first real marker point mark1 and the second real marker point mark2; since the fourth side shot by the second image acquisition module has no electrode, the image is not used; after shooting the first side and the fourth side, the first and second image acquisition modules can return to the initial position, that is, Figure 4 ​In the actual application, in the case of a single-electrode panel, a third image acquisition module can also be provided, and the second image acquisition module and the third image acquisition module capture the edge regions of the second side and the third side of the panel to obtain two second images. In this case, the panel does not need to be rotated.

[0066] In the actual application, in the case of a single-electrode panel, a third image acquisition module can also be provided, and the second image acquisition module and the third image acquisition module capture the edge regions of the second side and the third side of the panel to obtain two second images. In this case, the panel does not need to be rotated.

[0067] In the case of a double-electrode panel, as shown in FIG. 2, the first direction and the second direction are parallel; the edge region of the first side of the panel includes a first real marker mark1, the edge region of the second side adjacent to the first side of the panel includes a third real marker mark3, and the overlapping edge region of the first side and the second side of the panel further includes a second real marker mark2. Figure 5 In the case of a double-electrode panel, the image acquisition step specifically includes: the first image acquisition module moves along the first direction to capture the edge region of the first side of the panel and moves to acquire a first image, and the first image includes the first real marker mark1 and the second real marker mark2; and the second image acquisition module simultaneously moves along the edge region of the fourth side of the panel and acquires a second image, wherein the fourth side is adjacent to the second side, the second image includes the third real marker mark3, and the virtual marker mark3' corresponding to the third real marker mark3 can be determined according to the second image. In the case of a double-electrode panel, two image acquisition modules with parallel moving directions are used to independently acquire the first image and the second image, and the virtual marker mark' can be quickly determined without rotating the panel, thereby improving the panel edge detection efficiency.

[0068] It should be noted that each image acquisition module preferably simultaneously acquires images of the upper and lower sides of the panel during movement, that is, each image acquisition module comprises two camera modules, an upper camera module and a lower camera module, the upper camera module is used to capture images of the upper side of the panel from top to bottom, and the lower camera module is used to capture images of the lower side of the panel from bottom to top, so that for a panel stacked by a TFT substrate and a CF substrate, the upper camera module completes determination of the virtual marker points of the edge regions of the four sides of the substrate located on the upper side, and the lower camera module completes determination of the virtual marker points of the edge regions of the four sides of the substrate located on the lower side, so that determination of the virtual marker points of the edge regions of the eight sides of the panel can be quickly realized.

[0069] The present application also provides an embodiment as shown in a cutting precision detection method, comprising the following steps: Figure 6

[0070] S10 virtual marker point determination step: the position of the virtual marker point is determined by using the virtual marker point position determination method provided in the above embodiments of the present application;

[0071] S20 edge line detection step: the images captured by each side of the edge region of the panel are detected to detect the edge line of the panel; specifically, the CF substrate is located on the upper side of the TFT substrate, so that the edge line detected on the side of the panel having a step surface includes the edge line of the CF substrate and the edge line of the TFT substrate; the edge line detected on the other side without a step surface is the edge line of the CF substrate and the edge line of the TFT substrate since the CF substrate and the TFT substrate are flush.

[0072] S30 cutting precision determination step: the cutting precision of each side of the panel is calculated according to the virtual marker point, the real marker point and the outer edge line determined by the edge region of the panel. Specifically, the distance between the virtual marker point and the edge line (the edge line includes the length direction and the width direction edge line), the distance between the real marker point and the edge line, and the distance between the virtual marker point and the real marker point are calculated. In actual application, customization can be made according to customer's needs.
