针对织物数码印花过程中出现的飞线问题,以Hough变换理论为基础,结合图像处理技术,构建了一套数码印花飞线自动检测系统.通过Hou曲变换提取出图像的直线特征信息后,利用互相关系数检测出数码印花过程中出现的飞线问题,最后通过人工检测和检测结果比较发现,该系统较好地完成了数码印花飞线的自动检测.
Aiming at flying line for digital printing, with the combination of image processing, this paper presents a technology based on Hough transform to build a automatic detection system of flying line for digital printing. Through extraction of characteristic linear information in fabric image based on Hough transform, flying line for digital printing can be detected by the cross-correlation coefficient. Finally, through comparing with manual inspection, the technology can fairly well detect flying line for digital printing.
