Abstract

The invention discloses a method for digitalizing a cutting template, comprising the following steps of: marking parameters for a camera device of a measuring system to obtain internal parameters; utilizing the camera device to obtain an original image of a background and performing imaging correction and / or distortion correction and gray processing on the image to obtain a background gray image;putting a plane reference object with known area in the background, imaging the plane reference object, performing imaging correction and / or distortion correction, gray processing, differential operation and binary processing on the image to obtain nonzero pixels of an binary image of the plane reference object, and obtaining pixel equivalence of the measuring system; putting an object to be measured in the background, and obtaining nonzero pixels of an binary image of the object to be measured; transforming an binary image of the cutting template into an edge profile image of the cutting template; and according to pixel equivalence of the digitizing system of the cutting template, transforming the edge profile image of the cutting template into a vector image of the cutting template.

Description

technical field [0001] The invention relates to the field of digital image processing, in particular to a method for digitizing a cutting template. Background technique [0002] In the clothing, furniture, and other handicraft manufacturing industries, the role of cutting templates is very important. It is an important basis for cutting and sewing, and an important content of production technology management. Today, with the continuous development of digital image processing technology, digital management of templates has become possible. In addition, with the popularization of automatic computer-controlled cutting, it is necessary to convert the original cutting template into a computer-readable digital file. Since the shape of the cutting template is irregular straight lines and curves, the method of manual measurement cannot accurately and quickly enter the template. There is also no off-the-shelf device on the market. Contents of the invention [0003] The purpose o...
