[0002] Currently, in the glass deep processing industry, the imaging problem of glass has attracted particular attention. If the imaging of the glass after installation on the wall is not good, it will directly affect the visual effect of the glass product. Therefore, the detection of glass imaging is an important step in the production process. However, when actually producing glass, the imaging effect of the glass can only be observed outdoors during the day, and it is impossible to effectively detect the glass imaging at night. Therefore, related technologies achieve the detection of glass imaging at night through the method of on-line observation. Specifically, during the production process of the glass, the glass is laid flat, and the imaging situation of the lower sheet area lights and zebra stripes on the glass surface is used to on-line judge the glass imaging problem. However, due to the small area of the processing workshop and the limited visual range, the accuracy of the related technology for night glass imaging detection method is insufficient.

[0044] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0045] It should be noted that although functional module division is performed in the device schematic diagram and the logical sequence is shown in the flowchart, in some cases, the steps shown or described may be executed in a different module division in the device or a different order in the flowchart. Terms such as "first" and "second" in the description, claims and the above-mentioned drawings are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0047] Currently, in the glass deep processing industry, the imaging problem of glass has attracted particular attention. If the imaging of the glass is not good after it is installed on the wall, it will directly affect the visual effect of the glass finished product. That is, the detection of glass imaging is an important step in the production process. However, when actually producing glass, the imaging effect of the glass can only be observed outdoors during the day. That is, the glass is placed in a fixed position, and the operator stands at a certain distance from the glass, and judges the flatness of the glass through the imaging of nearby objects, so as to effectively simulate the visual effect after the glass is installed on the wall. However, at night, due to the lack of sunlight, it is very difficult to judge the flatness of the glass by observing the glass imaging, so the glass imaging detection cannot be effectively carried out at night. Related technologies realize glass imaging detection at night through an online observation method. Specifically, during the production process of the glass, the glass is laid flat, and the imaging of the lower sheet area light and the zebra stripes on the glass surface are used to judge the glass imaging problem online. However, due to the small area of the processing workshop and the limited visual range, the accuracy of the related technology's night glass imaging detection method is insufficient.

[0048] Based on this, the embodiments of the present application provide a night glass imaging detection system and method, a computer device, and a storage medium, aiming to improve the accuracy of night glass imaging detection.

[0049] Please refer to Figure 1 , Figure 1 which is a structural schematic diagram of the night glass imaging detection system provided by the embodiments of the present application. In some embodiments, the night glass imaging detection system 110 provided by the embodiments of the present application includes an illumination component 120, a second illumination member 130, and an imaging detection module 140.

[0050] Specifically, the lighting assembly 120 includes a first support structure 121 and a first lighting member 122 disposed at the top inside the first support structure. The first lighting member 122 forms a lighting area at the bottom of the first support structure 121, and the lighting area is the placement area of the target glass 150. The second lighting member 130 is mounted on the outdoor reference object 160, and the light-emitting side of the second lighting member 130 is disposed opposite to the outdoor reference object 160, so that the lighting light source of the second lighting member 130 is reflected on the outdoor reference object 160, and the target glass 150 can form a reference object image of the outdoor reference object 160 according to the reflected light of the second lighting member 130. The imaging detection module 140 is configured to perform imaging acquisition on the reference object image according to a preset sampling distance, and perform imaging detection on the acquired image to obtain an imaging detection result.

[0051] It should be noted that since the indoor space is relatively narrow and the flatness of the glass is important for its use in real life, therefore, in order to truly simulate the outdoor observation effect after the target glass is installed on the wall, the lighting assembly of the present application is used to provide a detection light source for the target glass at night.

[0052] It should be noted that the first support structure provided in the embodiments of the present application can be a ceiling, a light-shielding cloth, etc., which can enable the tester to perform imaging detection operations on the glass under any weather conditions, improving the practicability of the imaging detection. Moreover, the first support structure can also be used as a reference object in the embodiments of the present application to judge the flatness of the target glass by observing the imaging effect of the edge of the first support structure in the glass.

[0053] It should be noted that the first lighting member is disposed at the top inside the first support structure in the embodiments of the present application to facilitate providing a detection light source for the target glass. Among them, the first lighting member includes a middle light source and an observation light source. The middle light source irradiates vertically on the ground to provide overall brightness for the target glass. The observation light source can be oriented in different directions so that the target glass can observe the outdoor reference object at different positions from different angles.

[0054] It should be noted that the middle light source and the observation light source can be strong light lamps, and the brightness of the strong light lamps shining on the glass surface is 1000 - 3000 LUX.

[0055] It should be noted that the observation light source can include a front position light source and a rear position light source, and the included angle between the light irradiation directions of the front position light source and the rear position light source and the horizontal direction of the ground is any angle between 45° - 60°. For example, when the first support structure is a ceiling and the ceiling is located in an outdoor passage, outdoor reference objects for comparison can be selected on both outdoor sides of the ceiling.

[0056] It should be noted that in the actual scenario, the long-distance glass detection can more accurately reflect the flatness of the glass surface. Therefore, a second lighting component is provided on the outdoor reference object in this application. The light-emitting side of the second lighting component is arranged opposite to the outdoor reference object, and it can provide an illumination light source for the outdoor reference object, so that the illumination light source of the second lighting component is reflected on the outdoor reference object. For example, as Figure 2 shown, when the first support structure is the ceiling 210, and the ceiling 210 is located in the outdoor passage, with Building A and Building B on both sides of the outdoor passage, then the eaves 220 on Building A or the eaves 230 on Building B can be selected as the outdoor reference object. Therefore, a second lighting component is arranged below the eaves. That is, the second lighting component can be the row lights 240, so that the illumination light source of the row lights 240 is reflected on the eaves, and thus a reference object image of the eaves can be formed on the target glass according to the reflected light of the row lights 240.

[0057] It should be noted that when the second lighting component is the row lights installed on Building A, the row lights can also illuminate the wall of Building A, so that the wall is imaged on the target glass, and then the flatness of the image can be observed.

[0058] It should be noted that the outdoor reference object can be any object at any position in the imaging reference area of the target glass.

[0059] It should be noted that the imaging detection module includes a collection component and a detection component. The collection component can be a camera or a device with a camera to perform imaging collection on the reference object image on the target glass according to the preset sampling distance. Among them, the reference object image on the target glass can also be collected by moving the camera left and right, and any video frame can be selected as the image to be subjected to imaging detection, and the selected image should include the image of the outdoor reference object.

[0060] It should be noted that the video image is mainly used to observe the deformation of the middle part, simulating the imaging deformation state of the glass curtain wall during the walking process of people, so as to judge the glass deformation situation.

[0061] It should be noted that when performing imaging collection, the collection device needs to be perpendicular to the plate surface of the target glass to avoid data reading deviation caused by photographing at different angles.

[0062] It should be noted that the detection component can be a computer capable of implementing the night glass imaging detection method, and the collected image is input into the detection component for imaging detection.

[0063] Please refer to Figure 3 , Figure 3It is a schematic structural diagram of a glass placement component provided by an embodiment of the present application. In some embodiments, the night glass imaging detection system provided by the embodiment of the present application further includes: a glass placement component 310, which is arranged in the illumination area and used to place the target glass 320. The glass placement component 310 is provided with a first scale line arranged in the first direction and a second scale line arranged in the second direction, and the first direction and the second direction are perpendicular to each other.

[0064] It should be noted that the interval of each unit scale line in the first scale line and the second scale line can be set to 10mm, 50mm, etc., which is not specifically limited herein and can be flexibly set according to actual needs.

[0065] It should be noted that the image collected by imaging the reference object image needs to include the set first scale line and second scale line, so as to accurately judge the deformation range of the reference object in the glass according to the collected image, accurately determine the deformation level of the target glass, and thus improve the accuracy of night glass imaging detection.

[0066] Please refer to Figure 3 , in some embodiments, the glass placement component 310 includes a base 311 and a support frame 312 arranged on the base 311 for placing the target glass 320, and the included angle between the base 311 and the support frame 312 is any angle between 105 degrees and 120 degrees.

[0067] It should be noted that the inclination of the glass can reflect outdoor reference objects at a farther distance onto the target glass, so as to expand the amount of data that can be detected by the target glass. The glass placement component 310 of the present application includes a base 311 and a support frame 312 arranged on the base 311 for placing the target glass 320.

[0068] It should be noted that the glass placement component 310 further includes moving wheels installed on the base 311, which can flexibly move the glass placement component 310 within the placement area, so as to adjust the observation angle and position of the target glass 320.

[0069] It should be noted that the included angle between the support frame 312 for placing the target glass 320 and the plane of the first support structure is any angle between 15 degrees and 30 degrees. Therefore, the included angle θ between the base 311 and the support frame 312 is any angle between 105 degrees and 120 degrees.

[0070] Please refer to Figure 1 , in some embodiments, the night glass imaging detection system provided by the embodiment of the present application further includes: an anti-reflection layer 170, and the anti-reflection layer 170 is arranged on the imaging acquisition side of the imaging detection module.

[0071] It should be noted that since the application scenario of this application is night-time glass detection, in order to avoid the influence of ground reflection on the lighting effect, an anti-reflection layer is provided on the imaging acquisition side of the imaging detection module in the embodiments of this application, and the anti-reflection layer is provided in the direction of the imaging reference area of the target glass 150.

[0072] It should be noted that the anti-reflection layer 170 provided in the embodiments of this application can be an area painted with black paint, or a black anti-reflection cloth placed, and no specific limitation is made here.

[0073] Please refer to Figure 4 , Figure 4 is another structural schematic diagram of the night-time glass imaging detection system provided by the embodiments of this application. In some embodiments, the night-time glass imaging detection system provided by the embodiments of this application further includes: a second support structure 410, which is provided on both sides of the first support structure 420, and the second support structure 410 is used to form an imaging reference area for the target glass with the first support structure 420, and the outdoor reference object 430 is provided at any position within the imaging reference area.

[0074] It should be noted that the outdoor reference object adopted in the embodiments of this application can be any line or object within the imaging reference area.

[0075] It should be noted that please refer to Figure 2 , when the first support structure is a ceiling, the ceiling is located in an outdoor passage, and on both sides of the outdoor passage are Building A and Building B, then Building A and Building B are the provided second support structures. Building A, Building B and the outdoor passage constitute two imaging reference areas in opposite directions. Then, the imaging reference area to be sampled can be determined according to the orientation of the target glass, and any structure or object at any position within the imaging reference area can be selected as the outdoor reference object, or a visible structure or object outside Building A or Building B can be selected as the outdoor reference object, such as the eaves provided on Building A.

[0076] Exemplarily, the second support structure is arranged on both sides of the first support structure, the first lighting element forms a lighting area at the bottom of the first support structure, the lighting area is the placement area of the target glass, and the second support structure is used to form an imaging reference area of the target glass between the first support structure, and the outdoor reference object is arranged at any position in the imaging reference area. The second lighting element is installed on the outdoor reference object, and the light-emitting side of the second lighting element is arranged relative to the outdoor reference object, so that the lighting light source of the second lighting element is reflected on the outdoor reference object, and the target glass can form a reference image of the outdoor reference object according to the reflected light of the second lighting element. The placement area of the target glass includes a glass placement component for placing the target glass, and the glass placement component is arranged in the lighting area. The glass placement component includes a base and a support frame arranged on the base for placing the target glass, and the angle between the base and the support frame is any angle between 105 degrees and 120 degrees. In addition, the glass placement component is provided with a first scale line arranged in the first direction and a second scale line arranged in the second direction, and the first direction and the second direction are perpendicular to each other. In order to prevent ground reflection from affecting the lighting effect, an anti-reflective layer is set on the imaging acquisition side of the imaging detection module, so that the imaging detection module can image the reference object image according to the preset sampling distance and perform imaging detection on the acquired image. The first supporting structure adopted in the embodiment of the present application can provide a better glass observation environment for outdoor observation in any weather conditions.

[0077] The lighting fixtures installed at the front, middle and rear positions of the first support structure of the present application can provide all-round light, and can realize all-round observation of glass imaging. In addition, the second lighting fixture installed under the outdoor reference object can illuminate the outdoor reference object, so that the second support structure can be imaged onto the target glass, and then the glass flatness effect can be observed. In addition, the anti-reflective layer provided in the present application can effectively avoid the influence of moonlight or other light reflections on glass imaging observation, and by setting a preset sampling distance, it can help observers to collect images of glass imaging at different positions, so as to well simulate the visual effect of imaging of reference objects at different distances around the glass on the curtain wall glass surface after the glass is on the wall, thereby improving the accuracy of nighttime glass imaging detection.

[0078] It should be noted that the embodiment of the present application simulates the real wall glass imaging effect during the day at night, and the selected outdoor reference object can better obtain the real imaging effect. For example, if the target glass is tempered glass, a whole row of lights is illuminated upward on the side wall of building A, and projected onto the observed target glass to form a real image. When the image is detected to be basically free of deformation, it means that the imaging effect is excellent. When the image is detected to be curved, it means that there are ripples and the imaging effect is poor, and the tempering process of the glass needs to be adjusted.

[0079] See alsoFigure 5 , Figure 5 is a flowchart of the nighttime glass imaging detection method provided by an embodiment of the present application. In some embodiments, the nighttime glass imaging detection method is applied to the nighttime glass imaging detection system described in the above embodiment. Wherein, the preset sampling distance includes a first sampling distance, and the nighttime glass imaging detection method may specifically include, but is not limited to, steps S510 to S540.

[0080] Step S510: Image acquisition is performed on the reference object image formed on the target glass according to the first sampling distance to obtain a first imaging image;

[0081] Step S520: Imaging deformation detection is performed on the first imaging image to obtain first deformation data;

[0082] Step S530: Level judgment is performed on the first deformation data according to a preset deformation grading standard to obtain a first detection level;

[0083] Step S540: Determine the imaging detection result according to the first detection level and a preset target level.

[0084] In steps S510 to S520 of some embodiments, to better simulate the actual outdoor visual effect of a building, the present application can collect the imaging situation of an outdoor reference object on the glass surface from different sampling distances, so as to more comprehensively judge the flatness effect of the glass. Since the closer the distance, the better the imaging effect of the glass, first, image acquisition is performed on the reference object image formed on the target glass according to the first sampling distance to obtain a first imaging image. Since the glass placement component is provided with a first scale line arranged in a first direction and a second scale line arranged in a second direction, and the first imaging image collected also includes the corresponding scale lines, then imaging deformation detection is performed on the first imaging image according to the set scale lines to obtain first deformation data. This first deformation data is used to represent the bending deformation situation of the outdoor reference object.

[0085] It should be noted that the first sampling distance can be set to 5m, 10m, etc., and no specific limitation is made here.

[0086] In steps S530 to S540 of some embodiments, level judgment is performed on the first deformation data according to a preset deformation grading standard to obtain a first detection level. This first detection level is used to determine the detection result of the target glass according to the first imaging image. The preset detection levels include level 1 (excellent level), level 2 (qualified level), and level 3 (unqualified level), and the first detection level is any one of the preset detection levels.

[0087] Please refer to Figure 6 , Figure 6It is a flowchart of step S530 provided by an embodiment of the present application. In some embodiments, the first deformation data includes the middle deformation data and the edge deformation data of the first imaging image, and the deformation grading standard includes the middle grading sub-standard and the edge grading sub-standard. Then, step S530 may specifically include but is not limited to steps S610 to S630.

[0088] Step S610, determine the middle detection level by judging the level of the middle deformation data according to the middle grading sub-standard;

[0089] Step S620, determine the edge detection level by judging the level of the edge deformation data according to the edge grading sub-standard;

[0090] Step S630, determine the first detection level according to the middle detection level and the edge detection level.

[0091] In steps S610 to S630 of some embodiments, please refer to Figure 7 , since tempered / half-tempered glass is heated in a tempering furnace and then rapidly cooled in a wind grid, the heat received by the four sides of the glass (such as within 150 mm inward from the glass edge 710) is greater than that received by the middle region 720 of the glass during the production process, resulting in the glass edge being more likely to deform relative to the middle, that is, the hemming phenomenon occurs. Please refer to Table 1, which is a specific setting standard of the deformation grading standard provided by the present application. Specifically, in order to avoid the above phenomenon, the present application judges the level of the middle deformation data according to the middle grading sub-standard to determine the middle detection level, and judges the level of the edge deformation data according to the edge grading sub-standard to determine the edge detection level. Finally, the first detection level is jointly determined according to the middle detection level and the edge detection level.

[0092]

[0093] Table 1

[0094] It should be noted that the limitation of the hemming width of the glass edge 710 can be 100 mm, 150 mm, 200 mm, etc., and no specific limitation is made here.

[0095] It should be noted that the specific grading settings of the deformation grading standard can be flexibly set according to actual needs, and no specific limitation is made here.

[0096] It should be noted that the judgment of the middle deformation data can be made by manual observation or the level of the deformation width can be set according to actual needs.

[0097] Please refer to Figure 8 , Figure 8It is a flowchart of step S540 provided by an embodiment of the present application. In some embodiments, the preset sampling distance further includes a second sampling distance, and the first sampling distance is less than the second sampling distance. Then, step S540 may specifically include but is not limited to steps S810 to S840.

[0098] Step S810, when the first detection level is less than the target level, image the target glass according to the preset second sampling distance to obtain a second imaging image;

[0099] Step S820, perform imaging distortion detection on the second imaging image to obtain second distortion data;

[0100] Step S830, judge the level of the second distortion data according to the distortion grading standard to obtain a second detection level;

[0101] Step S840, when the second detection level is greater than or equal to the target level, determine the imaging detection result according to the second detection level.

[0102] In steps S810 to S840 of some embodiments, when the first detection level is less than the target level, that is, the first detection level is lower than the target level, the target level can be a qualified level or an excellent level, and the levels from high to low are: excellent level > qualified level > unqualified level. Therefore, image the target glass according to the preset second sampling distance to obtain a second imaging image. And perform imaging distortion detection on the second imaging image to obtain second distortion data. Then, judge the level of the second distortion data according to the distortion grading standard to obtain a second detection level. When the second detection level is greater than or equal to the target level, determine the imaging detection result according to the second detection level, and this imaging detection result is used to indicate that the target glass meets the standard for being able to leave the factory for use.

[0103] It should be noted that the second sampling distance can be set to 10m, 20m, etc., and no specific limitation is made here. And when it is 10m outside the first sampling distance, the second sampling distance must be greater than 10m.

[0104] It should be noted that in the embodiments of the present application, a black solid line is drawn at the positions of the first sampling distance and the second sampling distance from the target glass, so as to facilitate image acquisition of the reference object image formed on the target glass at different sampling distances.

[0105] It should be noted that when the first detection level is greater than or equal to the target level, the imaging detection result can be determined according to the first detection level, that is, it can be indicated that the target glass meets the standard for being able to leave the factory for use, and subsequent acquisition and detection are not required.

[0106] It should be noted that when the second detection level is still less than the target level, image acquisition of the target glass is performed according to a preset third sampling distance to obtain a third imaging image, and the third sampling distance is greater than the second sampling distance. Then, imaging deformation detection is performed on the third imaging image to obtain third deformation data, and level judgment is performed on the third deformation data according to the deformation grading standard to obtain a third detection level. When the third detection level is greater than or equal to the target level, the imaging detection result is determined according to the third detection level.

[0107] It should be noted that when the detection levels obtained within the preset sampling distance are all less than the target level, the current target glass is determined to be a defective product.

[0122] The night glass imaging detection system, method, computer device, and storage medium provided by the embodiments of the present application can, by setting the first support structure, better provide a glass observation environment for glass detection, enabling outdoor observation in any weather condition. At the same time, the flatness of the glass can be judged by observing the images formed by the edges and the middle part of the first support structure on the glass surface. The lighting lamps installed at the front, middle, and rear positions of the first support structure can provide omnidirectional light, enabling omnidirectional observation of the glass imaging. Moreover, the second lighting component installed under the outdoor reference object can illuminate the outdoor reference object, enabling the second support structure to be imaged onto the target glass, and then observing the flatness effect of the glass. In addition, the anti-reflection layer provided in the present application can effectively avoid the influence of moonlight or other light reflections on the glass imaging observation. By setting a preset sampling distance, it can help the observer collect images of the glass imaging at different positions, thus well simulating the visual effects of different-distance reference objects around the glass on the surface of the curtain wall glass after the glass is installed on the wall, and further improving the accuracy of night glass imaging detection.
