背景技术Background technique
目前，纺织企业为了减少库存，及时获取用户需要的纺织及皮革面料产品订单，经常要制作面料样册，既可以为用户提供整体面料的彩色图片，又可以提供实际的具有真实手感的面料样品，达到吸引客户和扩大销售量的目的。面料样册是由彩页装订起来而得到的。传统面料样册的彩页的结构图如图1所示。At present, in order to reduce inventory and obtain orders for textile and leather fabric products that users need in a timely manner, textile companies often make fabric sample books, which can not only provide users with color pictures of the overall fabric, but also provide actual fabric samples with real feel. To achieve the purpose of attracting customers and expanding sales. The fabric sample book is obtained by binding color pages. The structure diagram of the color page of the traditional fabric sample book is shown in Figure 1.
如图2所示，传统的面料样册的制作过程如下：（1）制作面料的图片彩页，一页有多个面料的彩图；（2）为了节省原料，先将真实销售的大幅面料切成5cm×6cm，6cm×8cm等不同尺寸的小块样品；（3）将小块样品粘贴到相应的面料彩页中对应面料图片的旁边位置。为了保证样品与宽幅面料的实际图片对应一致，需要加以检测以防止出错。防错检测就是要检测图1中的①和②、③和④是否对应一致，即检测面料彩图①是否来自面料样品②，面料彩图③是否来自面料样品④，防止出错。As shown in Figure 2, the production process of a traditional fabric sample booklet is as follows: (1) Make color pages of pictures of fabrics, one page has multiple color pictures of fabrics; (2) In order to save raw materials, first sell large-scale fabrics Cut into small samples of different sizes such as 5cm×6cm, 6cm×8cm, etc.; (3) Paste the small samples to the position next to the corresponding fabric picture in the corresponding fabric color page. In order to ensure that the sample corresponds to the actual picture of the wide-width fabric, it needs to be tested to prevent errors. Anti-error detection is to detect whether ① and ②, ③ and ④ in Figure 1 correspond to each other, that is, to detect whether the fabric color picture ① comes from the fabric sample ②, and whether the fabric color picture ③ comes from the fabric sample ④, so as to prevent mistakes.
传统的面料样册的制作和检测方法是人工粘贴及人工检测。人工检测的缺点是：需要大量工人，人力成本高，制作速度慢，检测效率低。The traditional methods of making and testing fabric sample books are manual pasting and manual testing. The disadvantages of manual detection are: a large number of workers are required, the labor cost is high, the production speed is slow, and the detection efficiency is low.
为了提高生产效率，需要采用自动化生产线来制作面料样册。但如何实现在线检测是个关键问题。由于目前的传统方法还是人工检测，检测环节的效率很低，人眼长时间工作容易疲劳，使得检测质量不稳定。而采用机器视觉检测系统直接对面料的图像内容进行识别也存在着技术难题：例如，一块大幅面的面料切成尺寸较小的、块数达到成百上千个的样品，其花纹、图案也被切成零碎的不同小块，每个小块的花纹、图案都不同，但代表的是同一种面料，这就给基于图像内容的识别带来了极大的困难，算法的复杂度巨大，机器视觉检测系统难以实现其基于图像内容的防错检测，这也是目前一个急待解决的技术问题。In order to improve production efficiency, it is necessary to adopt an automated production line to make fabric sample books. But how to realize online detection is a key issue. Since the current traditional method is still manual detection, the efficiency of the detection link is very low, and the human eye is prone to fatigue after working for a long time, making the detection quality unstable. There are also technical difficulties in using machine vision inspection systems to directly identify the image content of fabrics: for example, if a piece of large-format fabric is cut into smaller samples with hundreds or even thousands of pieces, the patterns and patterns are also different. Cut into different small pieces, each small piece has different patterns and patterns, but represents the same fabric, which brings great difficulties to the recognition based on image content, and the complexity of the algorithm is huge. It is difficult for the machine vision detection system to realize its error-proof detection based on image content, which is also an urgent technical problem to be solved at present.
