Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, exemplary embodiments according to the present invention will be described in detail below with reference to the accompanying drawings. It is to be understood that the described embodiments are merely a subset of embodiments of the invention and not all embodiments of the invention, with the understanding that the invention is not limited to the example embodiments described herein. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the invention described herein without inventive step, shall fall within the scope of protection of the invention.
As described above, in the existing panel inspection technology, only a part of an image of a panel to be inspected, for example, a partial electrode region currently focused by a user, is usually displayed on a display interface. It is difficult for the user to conveniently determine its position in the entire image based on the display contents, and it is inconvenient for the user to perform panel detection. Therefore, the present invention proposes a new image display method to solve the above technical problems.
Fig. 1 shows a schematic flow diagram of an image display method 100 of a panel to be inspected according to an embodiment of the present invention. As shown in fig. 1, the method 100 includes the following steps.
Step S110, an image of the panel to be detected is acquired.
The image of the panel to be detected may be an original image acquired by an image acquisition device such as a camera in the panel detection system, or may be an image obtained after preprocessing the original image. The preprocessing operation may include all operations for more clearly performing panel detection. For example, the preprocessing operation may include a denoising operation such as filtering. The image may contain all or part of the electrodes in the panel to be detected.
Step S120, a thumbnail of the image of the panel to be detected is generated.
It is understood that the thumbnail is a small image obtained by image compression processing of data in an image compared with the image of the panel to be detected. The image compression processing may include an operation of compressing an image of a large resolution into a thumbnail of a small resolution, an operation of replacing a plurality of pixels in the image with one pixel in the thumbnail, and the like, to reduce image data of the thumbnail. However, the positional relationship between the respective portions in the thumbnail images remains substantially the same as the positional relationship of the corresponding portions in the image of the panel to be detected. The thumbnail may provide a summary function for the image of the panel to be detected.
Alternatively, in the process of generating the thumbnail, the information of the region of interest in the image of the panel to be detected may be reduced less, and the information of the background region, such as the interval between the regions of interest, in the image of the panel to be detected may be reduced more.
Step S130, displaying a user interface.
FIG. 2 shows a schematic diagram of a user interface according to one embodiment of the invention. As shown in fig. 2, the user interface includes a first display area 210 and a second display area 220. The first display area 210 is used for displaying at least a portion of a region of interest in an image of a panel to be inspected. It will be understood by those skilled in the art that the image of the panel to be detected is acquired for detecting the panel to be detected, and the region of interest may be any region that a user wishes to detect, such as an electrode region on the panel to be detected. In the embodiment of the present application shown in fig. 2, the first display area 210 shows a portion of the electrodes in the image of the panel to be inspected, as indicated by the light gray rectangle in the middle of the right side of fig. 2. The second display area 220 is used to display a thumbnail and a first mark 221. The first mark 221 is used to mark the position of the region of interest displayed in the first display area 210 in the thumbnail image. I.e. the area marked by the first mark 221 corresponds to the area of interest currently displayed by the first display area 210. Thus, from the second display area 220, the position of the region of interest displayed by the first display area 210 in the image of the entire panel to be detected can be clearly observed. As shown in fig. 2, the region of interest currently displayed by the first display area 210 is located on the left side of the image of the entire panel to be detected.
According to the technical scheme, at least part of the interested area of the panel to be detected is truly displayed on the user interface, the thumbnail of the image of the panel to be detected is also displayed, and the position of the displayed interested area in the thumbnail is marked on the thumbnail. Therefore, the user can conveniently and quickly know the position of the currently displayed region of interest in the image of the panel to be detected based on the thumbnail. The panel detection method and the panel detection device provide convenience for the user to perform panel detection operation, and improve the use experience of the user.
Illustratively, the method 100 may further include the following steps.
Step S140, detecting the panel to be detected to obtain a defect area of the panel to be detected.
After the image of the panel to be detected is acquired, the panel to be detected can be detected. The flaw area in the area of interest of the panel to be detected can be determined through the panel detection item. Illustratively, the panel detection items may include the number, distribution, and offset degree of particles in the electrodes on the panel to be detected, and of course, whether there is a foreign object in and/or between the electrodes may also be detected. And obtaining the defective areas of the panel to be detected after detection, wherein each defective area can comprise one or more unqualified electrodes.
Step S150, the position of the defective area is determined in the thumbnail.
And determining the position of the flaw area in the thumbnail based on the position of the flaw area in the image of the panel to be detected. The user interface may also include a second indicia. The second mark is used to mark the location of the defect area in the thumbnail. When a defective area is detected, the defective area may be marked in the thumbnail and the second mark may be displayed in the second display area 220. Illustratively, the defective area may be boxed using a rectangular box, an oval box, or the like. Alternatively, the normal region in the defect region and the region of interest may be displayed with different colors.
According to the technical scheme, when the image of the panel to be detected is too large, a user can directly find the defective area in the image of the panel to be detected by using the position of the defective area determined in the thumbnail. Based on the thumbnail, the user can quickly find the flaw area, and a large amount of time is saved.
Illustratively, the method 100 may further include the following steps.
In step S160, in response to the user operating the second display area 220, the position of the current target region of interest in the thumbnail image determined by the user is acquired.
In a particular embodiment, the user may click on the second display area 220 with a mouse to select the current target region of interest on the thumbnail. The mouse is used for clicking more conveniently and quickly, and the operation of a user is facilitated. Alternatively, the user may also click or select a frame on the thumbnail by using an external device such as a touch screen or a touch pad to select the target region of interest. For another example, the user may also input the coordinates of the target region of interest to the system through an input device such as a keyboard to implement the above-mentioned operation of determining the current target region of interest. Through this operation, the user can quickly locate the current target region of interest using the thumbnail.
And S170, determining the position of the current target interest region in the image of the panel to be detected based on the position of the current target interest region in the thumbnail according to the position mapping relation between the image of the panel to be detected and the thumbnail.
As described previously, the positional relationship between the respective portions in the thumbnail images and the positional relationship of the corresponding portions in the image of the panel to be detected remain substantially the same. Namely, the image of the panel to be detected and the thumbnail have a unique position mapping relation. Each portion on the thumbnail has a unique corresponding portion in the image of the panel to be detected. The user selects the current target region of interest in the second display area 220 through the aforementioned step S160. After the target region of interest is selected, a rectangular frame can be generated in the thumbnail to mark the current target region of interest, and the position coordinates of four vertexes of the rectangular frame are obtained at the same time, so as to determine the position of the target region of interest in the thumbnail. According to the established position mapping relation and the position of the target region of interest in the thumbnail, the position of the target region of interest in the image of the panel to be detected can be determined.
Step S180, displaying the current target region of interest in the first display area 210 according to the position of the current target region of interest in the image of the panel to be detected.
After the position of the current target region of interest in the image of the panel to be detected is determined, the current target region of interest may be immediately displayed in the first display area 210, that is, the content of the first display area 210 is refreshed by using the current target region of interest. It will be appreciated that the content displayed in the first display area 210 thus corresponds to the same target region of interest of the panel to be inspected as the aforementioned user-defined region in the thumbnail. The first display area 210 may display different images in real time in response to a user's determination of a target region of interest for the second display area 220.
Therefore, the user can quickly position the target region of interest in the image of the panel to be detected only by selecting the target region of interest in the second display area 220 without other complicated operations, and the algorithm of the scheme is simple and easy to implement.
Exemplarily, the operation for the second display area 220 in the above step S160 may include a drag operation for the first marker 221. For example, the user may drag the first mark 221 by clicking the first mark 221 with a mouse and long pressing the left button of the mouse to change the position of the first mark 221 in the second display area 220, so that the target region of interest may be reselected.
Therefore, the user can freely drag the first mark 221 to realize the user-defined setting of the position of the target region of interest, the operation is simple, and the workload of the user cannot be increased while different requirements of the user are met.
Fig. 3 shows a schematic flow chart of the step of generating a thumbnail of the image of the panel to be detected at step S120 according to one embodiment of the present invention. As shown in fig. 3, step S120 may include the following steps.
Step S121, performing compression and extraction on all regions of interest in the image of the panel to be detected to obtain a region compressed image.
As mentioned above, taking an image of a panel to be detected as an example, the region of interest thereon may be thousands or even tens of thousands of electrodes. And as can be seen with reference to fig. 2, it is desirable to display the entire thumbnail on the user interface, whereby the length of the thumbnail is limited. Therefore, all the electrodes in the image of the panel to be detected can be compressed and extracted, for example, the number of the electrodes in the image of the panel to be detected is reduced by ten times, that is, ten electrodes in the image are represented by a specific graph after being compressed. By performing the above operation for all the electrodes in the image of the panel to be detected, a region compressed image can be obtained. Wherein, each specific pattern in the area compressed image can sequentially represent all electrodes on the image of the panel to be detected, and the area compressed image has a significantly reduced image data amount relative to the panel to be detected.
Step S122, performs distance projection transformation on the area compressed image to generate a thumbnail.
After the compressed region image is obtained in step S121, the compressed region image may be subjected to distance projection transformation according to the relative positions of the electrodes in the image of the panel to be detected, so that the specific patterns representing the regions of interest in the compressed region image maintain the same relative position relationship with the regions of interest in the original image of the panel to be detected, and a thumbnail is generated. The distance projection transformation scale can be reasonably set according to the occupied area of all interested areas in the image of the panel to be detected, the length of the thumbnail and the like.
Therefore, the image data in the thumbnail can be effectively reduced, and meanwhile, the reasonable reservation of the image data in the image of the panel to be detected is guaranteed.
Fig. 4 shows a schematic flowchart of step S121 of performing compression extraction on all regions of interest in the image of the panel to be detected to obtain a region compressed image according to an embodiment of the present invention. As shown in fig. 4, step S121 may include the following steps.
Step S121a, starting from the first region of interest of the image of the panel to be detected until the last region of interest ends, dividing each adjacent n regions of interest into a group.
Illustratively, taking an example that one region of interest is one electrode region, every adjacent n regions of interest in all regions of interest are divided into one group, that is, every adjacent n electrodes are divided into one group. For example, there are 4000 regions of interest on the image of the panel to be detected, and each adjacent 20 of them may be divided into one group, resulting in 200 groups of regions of interest. At this time, n is 20, and in practice, n may be set reasonably according to the user requirement or the number of the regions of interest in the image of the panel to be detected.
In step S121b, each group of regions of interest is replaced with a line segment to generate a region compressed image.
The 200 sets of regions of interest may be represented by 200 line segments, respectively, and the 200 line segments are arranged according to the arrangement order of the regions of interest to generate the region compressed image.
According to the technical scheme, the number of all the interested areas is equally divided, so that each line segment in the area compressed image can correspond to the same number of interested areas in the image of the panel to be detected, the image of the panel to be detected is effectively and reasonably compressed, the integrity and continuity of subsequently acquired image data of the thumbnail are ensured, and the algorithm is simple and easy to realize.
In a specific embodiment, the number n of regions of interest in each group can be calculated according to the following formula. n is Floor ((max (W)orig/Wthum,Horig/Hthum) Wherein W isorigWidth, W, of the image representing the panel to be inspectedthumDenotes the width of the thumbnail, obviously Worig/WthumRepresenting the ratio of the width of the image and the thumbnail of the panel to be inspected. HorigHeight of the image representing the panel to be inspected, HthumHeight of thumbnail, Horig/HthumRepresenting the ratio of the height of the image and the thumbnail of the panel to be inspected. max () denotes taking the larger of the two parameters in parentheses, i.e. at Worig/WthumAnd Horig/HthumTake a relatively large value. Floor () means rounding up the value in parentheses, i.e., rounding up the larger value obtained as described above. It is understood that rounding up means adding 1 to the previous integer as long as there is a decimal after the value.
Therefore, in the scheme, a larger numerical value is selected from the ratio of the width to the height of the image of the panel to be detected and the thumbnail, and the selected numerical value is rounded up. The method can ensure that the image data in the image of the panel to be detected is compressed and reserved in the thumbnail to the maximum extent, and greatly avoid the data loss in the image of the panel to be detected, so that a more accurate thumbnail can be obtained; in addition, the thumbnail can be completely displayed on the user interface, and the user can conveniently check the thumbnail.
Fig. 5 shows a schematic flowchart of step S122 of performing distance projection transformation on the area compressed image to generate a thumbnail according to one embodiment of the present invention. As shown in fig. 5, step S122 may include the following steps.
Step S122a, an average width W of the intervals between the regions of interest in each set of regions of interest is calculated.
In the foregoing embodiment, each group of regions of interest includes 20 regions of interest. In the image of the panel to be detected, every two adjacent interested areasWith a space therebetween. In this embodiment, there are 19 intervals in each set of regions of interest for the image of the panel to be detected. The average width W of the 19 intervals was calculated. Namely, it is
Where wi represents the width of the ith space. In the above embodiment, n is equal to 20.
Step S122b, compressing the average width W of the interval between the regions of interest in each group of regions of interest by n times to obtain the width I of the interval between two linescur。
Each group of the interested regions comprises n interested regions. In the above embodiment, n is 20. The average width of the 19 intervals is compressed by n times to obtain the width I of the interval between two line segments in the area compressed imagecur. I.e. the width I of the space between every two adjacent line segmentscur＝wi/n。
Step S122c, for the width I of the space between two segmentscurIf the number of pixels is less than the threshold value of the specific pixel number, the width I of the interval between the two line segments is determinedcurRounding up after expanding by a factor of m to obtain the width of the expanded space between the two line segments, where m is min (W)thum/(Bl+Br),T/Icur) Min () represents the smaller of the two parameters in parentheses, WthumIndicates the width of the thumbnail, BlAnd BrThe distance of the leftmost line segment in the area compressed image from the left side of the thumbnail and the distance of the rightmost line segment in the area compressed image from the right side of the thumbnail are respectively indicated.
When the width of the space between two line segments is IcurLess than a threshold value T for a particular number of pixels, e.g. the width I of the space between two line segmentscurOccupying less than 3 pixels, the spacing between the two segments is too small, which may cause the segments displayed in the thumbnail to appear to the user's eye to be connected and indistinguishable. Therefore, in order to avoid the above-described problem, the interval between the two segments can be increased. The magnification factor can be calculated by the formula: m is min (W)thum/(Bl+Br),T/Icur). Wherein, WthumRepresents the width of the thumbnail, e.g., the distance between the left and right sides of the thumbnail. B islRepresenting the distance of the leftmost line segment in the area-compressed image from the left side of the thumbnail, BrThe distance of the rightmost line segment in the area compressed image from the right side of the thumbnail is represented. B islAnd BrThe boundaries of the area compressed image may be limited. Wthum/(Bl+Br) A ratio of the width occupied by the area compressed image in the thumbnail image may be reflected, and it is understood that the larger the ratio, the wider the area compressed image occupies in the thumbnail image, i.e., the closer the leftmost line segment in the area compressed image is to the left side of the thumbnail image and/or the closer the rightmost line segment in the area compressed image is to the right side of the thumbnail image. Otherwise, the opposite is true. When the leftmost line segment in the area-compressed image coincides with the left side of the thumbnail and the rightmost line segment in the area-compressed image coincides with the right side of the thumbnail, the numerical value of the ratio is 1 at the minimum. It can be understood that when IcurT < T, T/IcurIs greater than 1. min () means taking the smaller of the two parameters in parentheses, Wthum/(Bl+Br) And T/IcurThe smaller value in between is taken as m. The width of the space between two segments can be expanded by a factor of m and the result rounded up to obtain an expanded space.
Therefore, the distance between each line segment can be reasonably set, the generated thumbnail can be ideally displayed, accurate mapping of the thumbnail and the image of the panel to be detected is ensured, and reliability of image data of the thumbnail is ensured.
