Image data processing method and system in Hunan embroidery plate-making process

Abstract

The invention relates to the technical field of image processing, and discloses an image data processing method and system in the plate making process of Hunan embroidery, so as to improve the plate making efficiency and the reuse rate of resources. The method includes: scanning to obtain a hand-embroidered pattern scan in a ratio of 1:1 corresponding to the artificial hand-embroidery pattern, dividing image areas of different colors into different layers according to the RGB values ​​of the hand-embroidery pattern scan, and dividing the same color image area into different layers. The image area is divided into the same layer; image recognition processing is performed on each layer, and during the recognition process of any layer, the stitches, connecting lines and texture features of the layer are recognized; The stitch points are mapped to the trend curve of the boundary contour after size scaling, and the connection lines between the stitch points after scaling are reconstructed; then the connection lines that exceed the maximum spacing range of the embroidery machine are divided; finally, the scaled layers are divided Superimpose to obtain the plate-making data file for the embroidery machine.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image data processing method and system in the Hunan embroidery plate-making process. Background technique [0002] Hand embroidery refers to the art of adding human design and production to any existing fabric with needles and threads by hand, and it is also one of the most precious species in China's intangible cultural heritage protection. [0003] At present, there are not many types of hand embroidery in China, which are mainly divided into "Su embroidery", "Yue embroidery", "Xiang embroidery" and "Shu embroidery". [0004] Hunan embroidery is one of the four famous embroideries in China. It is a general term for Hunan embroidery products with distinctive Hunan and Chu cultural characteristics centered in Changsha, Hunan. It originated from Hunan folk embroidery and developed by absorbing the advantages of Suzhou embroidery and Guangdong embroidery. It has a his...

Problems solved by technology

At present, most imitation manual embroidery plate-making based on Hunan embroidery is manually traced stitch by stitch in pattern-making software (such as: Tajima DG / ML by plus, Wilcom software, etc.) by referring to hand-embroidered samples; The plate-making efficiency is very slow, and the plate-making of a simple image also requires the operator who is skilled in operating the software to pay more than a week's work

Moreover, the reuse rate of the final plate-making file is low, and one size needs to correspond to an exclusive plate-making file; for example: a work corresponding to one square of the same image requires a special plate-making file, and the same image corresponds to four squares and nine squares ...and so on, respectively need one-to-one corresponding new plate-making files; the main reason for this result is that the thickness of the silk thread used in different sizes is fixed, and the scale of the silk thread cannot be synchronized with the scaling ratio of the presentation size Zooming; and even if it can be zoomed synchronously, the effect of the finished product is far worse than the expected zooming effect if silk threads of different thicknesses are selected based on the same plate-making file
