中文摘要: |
针织物商标图案加工过程中会产生形变,影响纺织品等级和质量。针对商标图案形变检测过程中出现倾斜现象而降低形变测量精度的问题,采用 Hough变换提取商标图案频谱图的旋转角度,以实现图案的倾斜校正。应用结果表明该算法能精确提取商标图案的倾斜角度并进行倾斜校正。算法不改变图案的原始形貌,提高了运行效率。 |
英文摘要: |
The appearance and quality of clothing is affected by the deformation of the fabric trademark pattern during manufacturing. But the measurement accuracy of deformation of trademark pattern is decreased due to trademark pattern tilting. In this paper the method based on the Fourier and Hough transform was proposed and used to measure and correct the rotation angle of tilted trademark pattern. The application shows that the method proposed can be used to correct the tilted fabric pattern. The algorithm guarantees the original shape of the pattern and improves the efficiency. |
