In different views, the same reference numerals designate corresponding parts.

[0046] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with its embodiments. It should be understood that the specific implementation manners described herein are only used to explain the present invention and do not limit the protection scope of the present invention.

[0047] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be a middle element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be a middle element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manners.

[0048] 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 the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific implementation manners and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0049] The "first" and "second" in the present invention do not represent specific quantities and orders, and are only used for name distinction.

[0050] In some cases, users have low requirements for the shearing accuracy of cold-rolled sheets and don't really care whether there are defects such as wrinkles, pitting, black lines and cracks in the cold-rolled sheets to be sheared, and often only need to shear out cold-rolled sheets of a certain length. Of course, in some other cases, users have diverse requirements for cold-rolled sheet shearing. For example, they need a certain number of cold-rolled sheets without defects such as wrinkles, pitting, black lines and cracks, and a certain number of cold-rolled sheets with only a general requirement for length.

[0051] In the above cases, corresponding shearing operations need to be carried out on the cold-rolled sheets specifically to better meet the different cold-rolled sheet shearing requirements of users.

[0052] In addition, for traditional cold-rolled sheet shearing devices, the shearing operation is often carried out by technicians relying on their naked eyes and experience, ignoring the defects existing in the cold-rolled sheets. It is impossible to construct a defect data model for cold-rolled sheets and shear cold-rolled sheets without defects according to the defect data model of cold-rolled sheets, and its structure needs to be improved.

[0053] To solve the above-mentioned technical problems, as Figure 1 shown, in an embodiment of the present invention, a cold-rolled sheet shearing system is provided, which includes a conveying device, a first data acquisition device, a second data acquisition device, a shearing device, and a control center.

[0054] The conveying device is used to convey the cold-rolled sheet to be sheared; the first data acquisition module is used to scan the cold-rolled sheet to be sheared to obtain the scanned data of the cold-rolled sheet to be sheared and feedback it to the control center.

[0055] Specifically, the conveying device includes a conveyor belt and a driving mechanism for driving the conveyor belt to move. The cold-rolled sheet to be sheared is placed on the conveyor belt and conveyed through the driving mechanism and the conveyor belt.

[0056] The first data acquisition module includes a scanner, which is used to scan the cold-rolled sheet to obtain scanned data. The scanned data includes, but is not limited to, the image information, temperature information, and dimension information of the cold-rolled sheet to be sheared.

[0057] The second data acquisition module is used to obtain the defect data of the cold-rolled sheet to be sheared and feedback it to the control center; the shearing device is used to perform the shearing operation on the cold-rolled sheet to be sheared according to the shearing instruction.

[0058] The second data acquisition module includes, but is not limited to, an industrial camera, and the shearing device includes, but is not limited to, a hydraulic shearing machine.

[0059] Since the second data acquisition module and the shearing device are both conventional technical means in the art, they will not be elaborated here.

[0060] The control center is used to receive the scanned data and defect data of the cold-rolled sheet to be sheared, construct a defect data model for the cold-rolled sheet to be sheared according to the scanned data and defect data of the cold-rolled sheet to be sheared, and generate a shearing instruction according to the shearing request and the defect data of the cold-rolled sheet to be sheared.

[0061] Among them, the shearing request includes the shearing length of the cold-rolled sheet, the shearing quantity, and the acceptable defects of the sheared cold-rolled sheet.

[0062] Since the shearing request includes the shearing length of the cold-rolled sheet, the number of sheets to be sheared, and the acceptable defects of the cold-rolled sheet to be sheared, the system generates a shearing instruction based on the shearing request and the defect data of the cold-rolled sheet to be sheared, and realizes the shearing operation of the cold-rolled sheet to be sheared based on the shearing instruction. It can perform corresponding shearing operations on the cold-rolled sheet according to the user's shearing request, so as to better meet the different cold-rolled sheet shearing needs of users.

[0063] In addition, the cold-rolled sheet shearing system first obtains the scanning data and defect data of the cold-rolled sheet to be sheared and constructs a defect data model of the cold-rolled sheet to be sheared, and then generates a shearing instruction according to the shearing request and the defect data of the cold-rolled sheet to be sheared, taking into account the defects existing in the cold-rolled sheet. It solves the problem that the traditional cold-rolled sheet shearing device performs shearing operations based on the naked eyes and experience of technicians, ignores the defects existing in the cold-rolled sheet, and is unable to construct a cold-rolled sheet defect data model and shear out a cold-rolled sheet without defects according to the cold-rolled sheet defect data model, improving the degree of intelligence.

[0064] In some cases, even at the same time point, there will be differences in the images of the same area of the cold-rolled sheet collected under different environments (such as different light brightness and different visions). Detecting and identifying cold-rolled sheet defects based on a single cold-rolled sheet image may result in misjudgments, such as misjudgments between bubbles and pinholes, and cracks and scratches. Therefore, even if defects are identified based on different images of the same area of the cold-rolled sheet collected at the same time point, there is still a possibility of misjudgment.

[0065] In order to improve the accuracy of cold-rolled sheet defect detection and identification, in one embodiment, the second data acquisition module includes a first acquisition unit, a second acquisition unit, a compensation unit, a fusion unit, and an acquisition unit.

[0066] The first acquisition unit is used to acquire the first image of the cold-rolled sheet to be sheared; the second acquisition unit is used to acquire the second image of the cold-rolled sheet to be sheared.

[0067] The compensation unit is used to extract the first image feature value of the first image and the second image feature value of the second image, and perform compensation and correction on the first image feature value and the second image feature value respectively according to the formula and The fusion unit is used to perform fusion processing on the compensated first image feature value and the second image feature value according to the formula

[0068] to obtain the fused image feature of the cold-rolled sheet to be sheared. The acquisition unit is used to obtain the defect data of the cold-rolled sheet to be sheared according to the fused image feature of the cold-rolled sheet to be sheared and feedback it to the control center;

[0069]

[0070] Among them, IFVC 1i represents the i-th vector component of the first image eigenvalue, IFVC 2i represents the i-th vector component of the second image eigenvalue, ω 1i represents the compensation correction factor of the i-th vector component of the first image eigenvalue, ω 2i represents the compensation correction factor of the i-th vector component of the second image eigenvalue, n represents the number of vector components of the first image eigenvalue, m represents the number of vector components of the second image eigenvalue, and merge() represents a preset image feature fusion function.

[0071] It is worth mentioning that, in order to ensure the associated graphs of the first image and the second image, the first image of the cold-rolled sheet to be sheared and the second image of the cold-rolled sheet to be sheared refer to the images of the same area of the cold-rolled sheet.

[0072] The compensation correction factor of the i-th vector component of the first image eigenvalue and the compensation correction factor of the i-th vector component of the second image eigenvalue can be set respectively based on the environmental parameters where the first acquisition unit is located and the environmental parameters where the second acquisition unit is located.

[0073] By extracting the first image eigenvalue of the first image and the second image eigenvalue of the second image, and respectively compensating and correcting the first image eigenvalue and the second image eigenvalue through the compensation correction factor of the i-th vector component of the first image eigenvalue and the compensation correction factor of the i-th vector component of the second image eigenvalue, the system takes into account the influencing factors of different environmental parameters on the cold-rolled sheet image.

[0074] Since the system takes into account the influencing factors of different environmental parameters on the cold-rolled sheet image, when performing fusion processing on the compensated first image eigenvalue and the second image eigenvalue to obtain the fusion image features of the cold-rolled sheet to be sheared, and then obtaining the defect data of the cold-rolled sheet to be sheared according to the fusion image features of the cold-rolled sheet to be sheared, and jointly identifying the cold-rolled sheet defect data with multiple cold-rolled sheet images under different visions, it can not only eliminate the differences in the images of the same area of the cold-rolled sheet caused by different environmental parameters, but also solve the problem of possible misjudgment in detecting and identifying the cold-rolled sheet defects based on a single cold-rolled sheet image.

[0075] In one of the embodiments, the cold-rolled sheet shearing system further includes an image acquisition module.

[0076] The image acquisition module is used to acquire the three-dimensional image of the cold-rolled sheet to be sheared; the control center is further used to perform cropping processing on the three-dimensional image of the cold-rolled sheet to be sheared according to the shearing instruction, and feed back the cropped three-dimensional image of the cold-rolled sheet to be sheared to the user terminal for visual display.

[0077] The image acquisition module can be a high-definition camera, installed at different orientations of the cold-rolled sheet to be sheared, and constructs the three-dimensional image of the cold-rolled sheet to be sheared by acquiring the real-time images of the cold-rolled sheet to be sheared from different perspectives and fusing the real-time images.

[0078] The cold-rolled sheet shearing system further includes a user terminal.

[0079] The user terminal is used to receive the cropped three-dimensional image of the cold-rolled sheet to be sheared fed back by the control center and perform visual display, and generate and adjust the shearing request.

[0080] The user terminal includes but is not limited to a mobile intelligent terminal.

[0081] After performing cropping processing on the three-dimensional image of the cold-rolled sheet to be sheared according to the shearing instruction, the cropped three-dimensional image of the cold-rolled sheet to be sheared visually displayed on the user terminal is actually the shearing preview effect diagram of the cold-rolled sheet to be sheared.

[0082] By feeding back the cropped three-dimensional image of the cold-rolled sheet to be sheared to the user terminal for visual display, it is convenient for the user to preview the shearing effect diagram, so as to adjust the shearing request, and further meet the cold-rolled sheet shearing needs of oneself.

[0083] In one embodiment, as Figure 2 shown, a cold-rolled sheet shearing method includes the following steps:

[0084] S1, provide a conveying device for conveying the cold-rolled sheet to be sheared.

[0085] S2, provide a first data acquisition module for scanning the cold-rolled sheet to be sheared to acquire the scanning data of the cold-rolled sheet to be sheared and feed it back to the control center.

[0086] Specifically, in step S2, the specific method for acquiring the defect data of the cold-rolled sheet to be sheared and feeding it back to the control center includes the following steps:

[0087] S20, collect the first image of the cold-rolled sheet to be sheared.

[0088] S21, collect the second image of the cold-rolled sheet to be sheared.

[0089] S22, extract the first image feature value of the first image and the second image feature value of the second image, according to the formula and Compensate and correct the first image eigenvalue and the second image eigenvalue respectively.

[0090] S23. According to the formula Fuse the compensated first image eigenvalue and the second image eigenvalue to obtain the fused image eigenvalue of the cold-rolled sheet to be sheared.

[0091] S24. Obtain the defect data of the cold-rolled sheet to be sheared according to the fused image eigenvalue of the cold-rolled sheet to be sheared and feedback it to the control center.

[0092] Among them, IFVC 1i represents the i-th vector component of the first image eigenvalue, IFVC 2i represents the i-th vector component of the second image eigenvalue, ω 1i represents the compensation and correction factor of the i-th vector component of the first image eigenvalue, ω 2i represents the compensation and correction factor of the i-th vector component of the second image eigenvalue, n represents the number of vector components of the first image eigenvalue, m represents the number of vector components of the second image eigenvalue, and merge() represents a preset image eigenvalue fusion function.

[0093] The vector components of the first image eigenvalue include but are not limited to the texture component, shape component, and color component of the first image eigenvalue, and the vector components of the second image eigenvalue include but are not limited to the texture component, shape component, and color component of the second image eigenvalue.

[0094] Preferably, the cold-rolled sheet shearing method further includes the following steps: obtain the compensation and correction factor of the i-th vector component of the first image eigenvalue according to the environmental parameters of the first image of the cold-rolled sheet to be sheared; obtain the compensation and correction factor of the i-th vector component of the second image eigenvalue according to the environmental parameters of the second image of the cold-rolled sheet to be sheared.

[0095] Specifically, the method for obtaining the compensation and correction factor includes the following steps: first construct a neural network model, obtain the standard compensation and correction factors of each vector component of the first image eigenvalue and the second image eigenvalue under a large number of different environmental parameters such as different visions and / or different light intensities, then train the neural network model based on the standard compensation and correction factors and the environmental parameters of the enemy camp, and finally obtain the real-time environmental parameters corresponding to the first image and the second image. According to the real-time environmental parameters and the trained neural network model, identify and obtain the compensation and correction factors of each vector component of the first image eigenvalue and the second image eigenvalue.

[0096] S3. Provide a second data acquisition module for obtaining the defect data of the cold-rolled sheet to be sheared and feedbacking it to the control center.

[0097] S4, provide a shearing device for implementing a shearing operation on a cold-rolled sheet to be sheared according to a shearing instruction.

[0098] S5, provide a control center for receiving the scanned data and defect data of the cold-rolled sheet to be sheared, constructing a defect data model of the cold-rolled sheet to be sheared according to the scanned data and defect data of the cold-rolled sheet to be sheared, and generating a shearing instruction according to a shearing request and the defect data of the cold-rolled sheet to be sheared.

[0099] Wherein, the shearing request includes the shearing length of the cold-rolled sheet, the shearing quantity, and acceptable defects of the cold-rolled sheet to be sheared. The purpose of constructing the defect data model of the cold-rolled sheet to be sheared is to identify the type of cold-rolled sheet defects and the specific coordinate positions of the defects on the cold-rolled sheet according to the defect data model of the cold-rolled sheet to be sheared, so as to perform a shearing operation on the cold-rolled sheet according to the shearing request.

[0100] Since the method takes into account the influencing factors of different environmental parameters on the cold-rolled sheet image, when performing a fusion process on the compensated first image feature value and the second image feature value to obtain the fused image feature of the cold-rolled sheet to be sheared, and then obtaining the defect data of the cold-rolled sheet to be sheared according to the fused image feature of the cold-rolled sheet to be sheared, and identifying the defect data of the cold-rolled sheet by combining multiple cold-rolled sheet images under different visions, it can not only eliminate the differences in the images of the same area of the cold-rolled sheet caused by different environmental parameters, but also solve the problem of possible misjudgment in detecting and identifying cold-rolled sheet defects based on a single cold-rolled sheet image.

[0101] In one embodiment, the cold-rolled sheet shearing method further includes the following steps:

[0102] Obtain a three-dimensional image of the cold-rolled sheet to be sheared;

[0103] Perform a cropping process on the three-dimensional image of the cold-rolled sheet to be sheared according to the shearing instruction, and feed back the cropped three-dimensional image of the cold-rolled sheet to be sheared to a user terminal for visual display.

[0104] After performing a cropping process on the three-dimensional image of the cold-rolled sheet to be sheared according to the shearing instruction, the cropped three-dimensional image of the cold-rolled sheet to be sheared visually displayed on the user terminal is actually a shearing preview effect diagram of the cold-rolled sheet to be sheared. In this way, it can facilitate the user to preview the shearing effect diagram to adjust the shearing request, so as to meet the user's own cold-rolled sheet shearing requirements.

[0105] In one embodiment, a computer-readable storage medium stores a computer program, and when the computer program is executed, the cold-rolled sheet shearing method is implemented.

[0106] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.

[0107] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
