摘要:

为实现自动检测织物图案周期和印花织物质量的有效评估,保证在纺织工业中图案织物生产的高速性和织物的高质量性。本文运用距离匹配函数计算印花织物周期,基于印花织物图案的周期性,本文首先计算印花织物图案的各行和各列的一维距离匹配函数,然后对织物所有行和所有列的一维距离匹配函数求和作为行和列的二维距离匹配函数。当距离匹配函数中的周期变量为织物图案周期时,印花织物距离匹配函数二次前差分得到最大值。实验结果表明,距离匹配函数测量各类织物周期具有高效性和准确性。与传统的自相关函数检测织物周期相比,该算法检测织物周期准确且可检测织物各种图案的周期。

Abstract:

 In order to realizing automatic detection of fabric design cycle and the quality evaluation of printed fabrics effectively are necessary, and high-speed of fabric design production in the textile industry and well quality of fabrics should be ensured. In this paper, cycle of printed fabrics is determined via calculating distance matching function. One-dimensional distance matching function in each row and each column of patterned fabrics is calculated firstly based on cyclical pattern of fabrics, and the sums of distance matching function on all rows and columns are acted as two-dimensional distance matching function on row and column. When the cycle variable in two-dimensional distance matching function is the cycle of patterned fabrics, second forward difference of two-dimensional distance matching function reaches maximum. The experimental results show cycles of all kinds of fabrics detected by two-dimensional distance matching function are efficiency and accuracy. Compared with detection of patterned cycle of traditional autocorrelation function, proposed method of this paper can achieve accurate detection of patterned cycle, and various patterned cycle of fabrics can be inspected, thus a foundation is provided for real-time operation in industry.

Key words: printed fabrics, cycles of patterned, distance matching function, forward difference
