超宽幅扫描仪配套织物疵点检测软件设计

Design of fabric defect detection software correspond to ultra-wide image scanner

针对超宽幅扫描仪在获取织物图像过程中容易出现的几何失真现象,以及需要对织物在制造过程中出现的疵点进行检测等问题,设计了与之配套的数字图像处理软件。采用可视化编程工具Delphi进行了编程,利用坐标变换、灰度内插等方法得到了相应的几何校正图像,并通过与标准织物图像进行了图像匹配,实现了目标织物的疵点检测。实验结果表明,该软件能够快速、准确地检测出织物疵点,对提升织物检测技术水平和加强产品质量控制,具有重要的现实意义。

A bundled software for ultra-wide image scanner was provided to solve the problems of image geometric distortion when images were captured with a ultra wide scanner, and the problems of spot defects when the textile was weaved. The system procedure was pro- grammed with the visual programming tool Delphi. The correct image was achieved by the use of coordinate transformation and gray interpola- tion method, and the theory of sequence images registration was used to realize the purpose of detect inspection. The results indicate that the software can detect the fabric defects quickly and accurately, and it also has important practical significance to improve the detection technol- ogy level and to enhance the quality control of products.
