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
