Embodiment 3

[0035] Embodiment 3 is basically the same as Embodiment 1 and Embodiment 2, the difference is that the fabric texture feature extraction device uses photocells, the width of the photosensitive area is less than 1 / 2 of the grain spacing, and the length of the photosensitive area is greater than ten grain spacings , the length direction of the photosensitive area is parallel to the weave direction of the fabric to be detected, and the photosensitive device perceives the alternating changes in the intensity of light generated by the movement of the fabric weave, and converts it into an alternately changing level signal, which is used as the weaving texture on the surface of the moving fabric Information, the computer samples the output level of the photocell, and directly performs digital filtering on the sampling result. In embodiment 3, the photocell can be replaced by photosensitive devices such as photoresistors.

Abstract

The present invention relates to on-line detection technology, and fabric texture detecting method and apparatus for detecting and outputting the texture characteristic information of fabric in motion. The fabric texture detecting apparatus includes at least one characteristic extracting device to scan moving fabric under detection to obtain texture characteristic information in at least one direction; one data processing device to process the extracted basic fabric texture characteristic information and to obtain and record the moving amount of each basic woven texture of the moving fabric. The said fabric texture detecting method and apparatus can overcome the influence of shrinkage, tension fluctuation and other causes on alignment, and may be used widely in different fields needing fabric pattern matching, especially in fabric printing, automatic embroidery, automatic cutting, etc.

Description

technical field [0001] The invention relates to the on-line detection technology of fabric printing and dyeing, automatic embroidery and automatic cutting, in particular to the fabric texture detection method and device in the on-line detection technology. Background technique [0002] For the printing and dyeing, embroidery and automatic cutting process of fabrics, a motion control system is required for fabric pattern matching. Due to the deformation of the fabric itself caused by shrinkage or tension changes in the above process, errors occur in the process of fabric pattern matching. At present, there is no effective solution to such errors. In the 7th issue of Jiangsu Textile in 2003, an article titled "Realization of Rotary Screen Printing Machine Alignment Accuracy Detection System" proposed an accurate alignment system as a subsystem of the "Rotary Screen Printing Machine Fully Automatic Closed-loop Alignment System". It is unique in that the method works by detecti...
