Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of textile production process and equipment, and particularly relates to a fabric flaw processing method and a corresponding cloth inspection and cutting system. BACKGROUND

[0002] China is one of the world's textile industry bases, and the textile industry plays an important role in the country's economic development. At present, on the one hand, China is facing the pressure of poor domestic sales of textile and garment and significant decline in textile and garment exports; on the other hand, the labor cost is rising at a faster rate than the productivity improvement, and the survival pressure of enterprises is increasing. In the new stage of industrial transformation, major textile enterprises are striving to improve their product quality, and high standards mean higher fabric detection and cutting costs. How to reduce manual participation, improve fabric raw material utilization, optimize cutting methods, and accelerate production automation is the challenge currently faced.

[0003] The textile industry has clear divisions, and its industry chain includes the production and processing of raw materials, textile processing, garment manufacturing, and finally the consumer. Taking a garment manufacturing enterprise as an example, a cloth inspection line is generally set up at different production sites to perform a fabric flaw inspection process; a fabric office performs fabric pattern management and input; and a cutting line performs cutting control according to the fabric pattern and fabric raw material.

[0004] The garment manufacturing enterprise has found in production that if a flaw appears in an important area such as the neckline or chest (in this application, the area on the fabric corresponding to these important areas is referred to as a sub-block of the fabric. The sub-block of the fabric has a huge impact on the quality of the entire garment.), i.e., the flaw is located on the sub-block of the fabric, then the garment needs to be abandoned as a whole; and a flaw appearing in an unimportant location such as the pant leg has a smaller impact on the quality of the entire garment. In the existing production mode, the garment manufacturing enterprise can only judge the fabric quality according to the fabric raw material grade provided by the cloth factory, and the final garment effect can only be understood after cutting, and once the fabric is cut, it is assumed that the fabric is accepted, which increases the quality risk and increases the production cost of the enterprise.

[0005] In the traditional fabric flaw processing method, the main process is fabric flaw inspection, which has been manually inspected for a long time, and the efficiency is low, the labor intensity is high, and the inspection result is subjective and not reliable. Based on the development of science and technology, machine vision and artificial intelligence have been applied to fabric flaw detection, and some defects in manual detection have been improved. However, fabric flaw processing is still an independent quality inspection process, and its result is mainly used for quality standard evaluation. The production space layout and process stage time sequence limit the optimization of overall production efficiency even if automatic intelligent manufacturing equipment is invested to improve fabric flaw detection, which is not conducive to the further development of textile enterprises.

[0006] Therefore, it is very necessary to study a cloth defect processing method and a corresponding cloth inspection and cutting system, which can be applied to textile production, especially clothing enterprises, can inspect and evaluate cloth defects before clothing production, combines cloth defects with cloth cutting blank map, provides an optimized cutting scheme, reduces quality risk, saves cost, strengthens enterprise competitiveness, and further promotes the in-depth development of textile production industry and the improvement of industry level.

[0015] In the step S4 or after the step S4, the optimal offset distance is obtained, and the offset distance is adjusted according to the optimal offset distance to reduce the waste ratio.

In step S4, if there is a defect with a defect level higher than the tolerable defect level of the sub-block falling into the sub-block or a defect with a defect level higher than the tolerable defect level of the cutting cloth falling into the cutting cloth, the cutting cloth is determined as waste; the area of the waste and the proportion of the waste area to the area of the whole cloth, i.e. the waste ratio, are calculated. In this embodiment, the defect level is divided into multiple levels according to the severity of the defect, and the tolerable defect level of the sub-block is lower than the tolerable defect level of the corresponding cutting cloth.

[0040] In this embodiment, after step S4, the cloth quality is also evaluated, and the evaluation standard includes the waste area and the waste ratio. In this embodiment, the area and the proportion of the discarded cloth after cutting and making clothes are used to measure the quality of the cloth, and the traditional cloth quality evaluation standard only relies on the type of defect to deduct points, often ignoring the influence of the position of the defect on the overall quality.

[0042] Embodiment Two

[0043] In Embodiment Two, the processing of the image acquisition module 1 is specifically an image processing software realized by using HALCON machine vision software in combination with QT programming. The operation flow of the image processing software is as shown in Figure 5 As shown, the main parts include image splicing, image cutting, edge extraction, label classification, and result screening. In this embodiment, the original file of the fabric image is in pdf format, and the parts to be extracted include text and cutting fabric coordinate information. The above work can be completed by using pdfminer3k in python. The extracted coordinates first need to remove the inner contour of the fabric. The inner contour in the original contour array is an even index, and only the odd index points need to be extracted to obtain the result. In addition, since the extracted points use the Cartesian coordinate system, and the QT program uses the image coordinate system, the coordinates need to be converted according to the height of the display control. The formula is as follows:

[0044]

[0045] In this embodiment, the image obtained can be displayed on the PC display of the first computer 11, or on any PC, and of course can also be displayed through the display device of the defect matching module 3, and is not limited.

[0046] In this embodiment, QT is a graphical user program framework, which is an object-oriented encapsulation of the underlying application programming interface API. It is a class library based on C++ language, focusing on but not limited to the development of graphical user interface, and can also be used for system call, network programming, database, 2D / 3D graphics processing. The QT program in this embodiment uses QT programming. Since it is based on C++ language, it is simple, easy to use, object-oriented (for GTK), has excellent cross-platform characteristics, and is easy to extend. The flow and specific software in this embodiment are for the purpose of facilitating the understanding of this embodiment, but they cannot limit the specific ways and methods of image processing in other actual cases.

[0047] In this embodiment, the specific method for calculating the area of the waste is realized by integrating the defect matching software in the defect matching module 3. When the defect matching software is running, the operation is first performed according to the length information of the fabric and the width of the fabric cutting fabric image to calculate the number of times of repeated expansion Then the labeled cutting material map is combined with the defect position information. If there is a defect falling into the sub-block or a defect falling into the cutting material itself which is higher than the tolerable level, it is calculated as waste, and finally the area of the waste is calculated. The polygon area calculation uses the Gauss area formula. Suppose the number of vertices of a polygon is n, and its area is , the coordinates of any vertex are The formula is as follows:

[0048]

[0049] Wherein

[0050] In this embodiment, the maximum offset distance of the search and the step length of each increase are configured in advance in the defect matching software. The search starts from the offset distance preset value of 0 cm, the best offset distance is automatically obtained, and the adjustment is automatically made according to the best offset distance. The optimal waste ratio is obtained through the adjustment, so as to save the cloth.

[0051] In this embodiment, in the step S4, a cloth with a drawn defect is matched with multiple cloths, and the number of clothing patterns and the remaining cloth length of each cloth are calculated. According to the matching result of each cloth, the cloth suitable for the specified material is selected for cutting. The matching result includes the number of clothing patterns and the remaining cloth length, and also includes the waste area and / or the waste ratio. The matching result of multiple cloths is shown in Figure 6 , which shows the information such as the length loss (remaining cloth length), waste ratio, and number of clothing patterns of each cloth after the specified material map is matched with multiple cloths. According to the matching result, the most suitable cloth for the specified material can be selected manually or automatically according to the preset rule for cutting, which optimizes the cutting method.
