Embodiment Construction
[0037] The present invention will be described in detail below with reference to the drawings and specific embodiments.
[0038] The invention provides a method for pairing horizontal strips of garment pieces based on image matching.
[0039] A method of aligning the horizontal strips of garment pieces based on image matching, such as figure 1 As shown, follow the steps below:
[0040] Step 1. Perform image collection on the pieces that need to be stitched;
[0041] Step 1 is specifically: place the pieces to be stitched on a solid-color background board, and use a camera with more than 5 million pixels to collect images;
[0042] Step 2. Perform image grayscale on the captured image; because the image captured by the camera is an RGB image, the amount of data directly processed is large, and the color requirements of the piece segmentation are not high, so the color image is grayscaled.
[0043] Step 2 According to formula (1), the image is grayed out,
[0044] Y=0.299R+0.587G+0.114B (1...

A garment-making cutting piece cross stripe alignment method based on image matching disclosed by the invention is implemented according to the following steps: S1, acquiring an image; S2, graying the image; S3, performing threshold segmentation on the image to get a plurality of cutting piece binary images; S4, performing hole filling on each pair of binary images in need of cross stripe alignment to eliminate the jagged edges in each pair of cutting piece binary images; S5, performing AND operation on each pair of cutting piece binary images and the original image to get each pair of segmented cutting piece images; S6, correcting the positive direction of cutting piece of each pair of segmented cutting piece images; S7, selecting a to-be-sewn area of one cutting piece from each pair as a template; S8, matching the to-be-sewn area of the other cutting piece to get a maximum response position; and S9, calculating the moving distance of the cutting piece according to the maximum response position and the original position of the template, and moving the cutting piece according to the moving distance to complete cutting piece cross stripe alignment. Through the method, there is no need for manual cross stripe alignment.
Description
Technical field [0001] The invention belongs to the technical field of textile garment pieces, and in particular relates to a method for aligning horizontal strips of garment pieces based on image matching. Background technique [0002] In the garment making process of textile and garment enterprises, workers need to sew several pieces of pieces together by hand, especially for high-end shirts with stripes and lattices. The stripes and lattices of the pieces sewn together are aligned with each other. To meet customers' aesthetic requirements and improve product value. However, due to rising labor costs, high competition pressure from textile and garment enterprises, and restrictions on overtime hours imposed by the Labor Law, the textile and garment industry needs a new kind of productivity to increase corporate efficiency. At present, some domestic advanced textile and garment enterprises have begun to explore fully automatic garment making technology, hoping to realize automat...
