Abstract

The invention discloses an image calibration method and device, electronic equipment and a storage medium. The method comprises the step of obtaining a proportion value of a pixel length and an actuallength of an image of each calibration point in a calibration pattern, wherein the proportion value of the pixel length and the actual length of any pixel point in the image acquired by image acquisition equipment is set by taking the proportion value of the pixel length and the actual length of the pixel point corresponding to the image of the calibration point adjacent to the pixel point as a reference value. The image calibration method is highly automatic, simple to operate, less prone to errors, low time complexity and space complexity of the algorithm, low in dependence on external conditions such as illumination and the like and particularly suitable for sewing machinery in an actual working environment.

Description

technical field

[0001] This application relates to the field of sewing / sewing technology, in particular to an image calibration method, device, electronic equipment and storage medium. Background technique

[0002] Sewing\Sewing generally refers to the production process that can form stitches on various materials such as cloth (hereinafter referred to as fabric). Sewing machines, embroidery machines, etc. are all sewing machines. Modern sewing machinery is controlled by electronic equipment and produced according to patterns, which can realize the automation of the sewing process. A pattern is a data file containing production-related data such as sewing image data, and a pattern that can be recognized by a sewing machine can be made by using plate-making software or other software.

[0003] With the continuous development of sewing technology, the forms of sewing production are also varied. For example, image acquisition devices such as cameras and cameras can be installe...
