DETAILED DESCRIPTION

[0018] Many specific details are described in the following description to facilitate a full understanding of this specification. However, this specification can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of this specification, so this specification is not limited to the specific implementation disclosed below.

[0019] The terms used in one or more embodiments of this specification are only for the purpose of describing specific embodiments, and are not intended to limit one or more embodiments of this specification. The singular forms of "a" and "the" used in one or more embodiments of this specification and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings. It should also be understood that the term "and / or" used in one or more embodiments of this specification refers to and includes any or all possible combinations of one or more associated listed items.

[0020] It should be understood that although the terms first, second, etc. may be used to describe various information in one or more embodiments of this specification, this information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of one or more embodiments of this specification, the first may also be referred to as the second, and similarly, the second may also be referred to as the first. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0021] For conventional float glass or electronic glass, due to its good light transmittance, bubbles in the glass will cause stress changes in the surrounding glass, and the bubbles are usually imaged using a deformable light source or streak light transmission method; but for microcrystalline glass, which has poor light transmittance and a rough surface, the transmission method can only reveal larger bubbles, while other smaller bubbles are hidden in the rough surface structure and are difficult to present.

[0022] Usually, the thickness of the central area of ​​microcrystalline glass is less than 1.0mm. Due to the various shapes of bubbles, when the roughness of the glass surface increases, it is easy to produce defects such as pits and orange peels, which are very similar to the defects on the glass surface, but the damage to the quality of glass by different defects varies greatly. Generally, pits and orange peels can be thrown away in the downstream polishing process, while bubbles on the surface of different levels are difficult to throw away. Whether using traditional image processing algorithms or deep learning algorithms, it is difficult to distinguish bubbles hidden in the rough surface. Based on this, the embodiments of this specification provide a method for detecting bubbles in a microcrystalline glass ribbon, which is described as follows.

[0023] In this specification, a method for detecting bubbles in a microcrystalline glass ribbon is provided. This specification also relates to a device for detecting bubbles in a microcrystalline glass ribbon, a computing device, and a computer-readable storage medium, which are described in detail one by one in the following embodiments.

[0024] See also Figure 1 , Figure 1 A flow chart of a method for detecting bubbles in a glass-ceramic ribbon provided according to an embodiment of the present specification is shown, which specifically includes the following steps.

[0025] Step 101: Illuminate the glass-ceramic through at least two lamp beads and acquire an image of the glass-ceramic; wherein the at least two lamp beads are respectively located on two sides of the glass-ceramic.

[0026] In a possible implementation, at least two lamp beads are strobe fiber optic lamps; at least two lamp beads include a first row of lamp groups, a second row of lamp groups, a third row of lamp groups and a fourth row of lamp groups; the microcrystalline glass is placed horizontally; the first row of lamp groups and the second row of lamp groups are arranged on the left side of the microcrystalline glass, and the first row of lamp groups are arranged on the upper side of the microcrystalline glass, and the second row of lamps are arranged on the lower side of the microcrystalline glass; the third row of lamp groups and the fourth row of lamp groups are arranged on the right side of the microcrystalline glass, and the first row of lamp groups are arranged on the upper side of the microcrystalline glass, and the second row of lamps are arranged on the lower side of the microcrystalline glass.

[0027] In practical applications, due to the microcrystalline structure of glass itself, it has a certain light-conducting property. Therefore, high-intensity fiber optic lamps are used to illuminate the side edges of the glass. Light is incident from the side edges and illuminates all layers of bubbles in the glass under the light guidance of the microcrystalline structure along the irradiation direction. This makes it difficult to distinguish between bubbles and dust. On one side of the glass, two rows of lamp beads are used to strobe the glass in a time-sharing manner. Then the camera collects images for further analysis. To ensure a good irradiation range, see Figure 2 , strobe fiber optic lights are installed on both sides of the glass, and they are lit up in time under a unified external trigger signal.

[0028] Step 102: Determine a first illumination image and a second illumination image based on the glass-ceramic image.

[0029] In one possible implementation, determining a first illumination image and a second illumination image based on a glass-ceramic image includes: performing data stripping based on the glass-ceramic image to determine the first illumination image and the second illumination image; wherein the first illumination image is an image illuminated by the upper lamp beads, and the second illumination image is an image illuminated by the lower lamp beads.

[0030] In practical applications, the fiber optic lamp is lit by staggered time-sharing stroboscopic method. After the camera captures a complete frame of image, the odd and even line image data are stripped out and reassembled into two images, namely the odd line image (irradiated by the upper lamp beads) and the even line image (irradiated by the lower lamp beads).

[0031] Step 103: Determine brightness information based on the first illumination image and the second illumination image.

[0032] In one possible implementation, brightness information is determined based on the first illumination image and the second illumination image, including: traversing pixel positions in the first illumination image to obtain first pixel value information; traversing pixel positions in the second illumination image to obtain second pixel value information; and determining brightness information based on the first pixel value information and the second pixel value information.

[0033] In practical applications, the pixel values ​​(0-255) of the same position of the odd-numbered line graph and the even-numbered line graph can be taken out respectively.

[0034] Step 104: Perform bubble detection based on the brightness information to determine the bubble detection result.

[0035] In one possible implementation, bubble detection is performed based on brightness information to determine a bubble detection result, including: determining a brightness threshold, determining a first abnormal position based on first pixel value information and the brightness threshold; determining a second abnormal position based on second pixel value information and the brightness threshold; and determining a bubble detection result based on the first abnormal position and the second abnormal position.

[0036] Specifically, determining the bubble detection result based on the first abnormal position and the second abnormal position includes: determining the bubble position information when the first abnormal position and the second abnormal position are the same; and determining the bubble detection result based on the bubble position information.

[0037] In practical applications, if it is a bubble, the bubble is very bright in the first illumination image and the second illumination image. The judgment method can be determined by the gray value. Preferably, the gray value is ≧150. If it is dust, it can be found that one image is brighter (gray value ≧100) and the other image is not obvious (gray value ≦30). The bubble position information can be determined by the above method, that is, the following method is obtained: Bubble defect graph = odd line graph & even line graph.

[0038] In a possible implementation, determining the bubble detection result based on the bubble position information includes: determining the bubble position pixels and the non-bubble position pixels based on the bubble position information; setting the pixel values ​​of the bubble position pixels to 255; and setting the pixel values ​​of the non-bubble position pixels to 0.

[0039] In practical applications, in order to improve the contrast, if a certain position in both images is bright, the pixel value of the position in the bubble defect image is 255. If one is bright and the other is dark, the pixel value of the position in the bubble defect image is 0. After traversing the entire image, a complete bubble defect image is obtained, in which the bright area is the bubble and the dark area is the background (not the bubble). In this way, the bubble detection can be realized and the influence of factors such as dust can be avoided.
