Embodiment

[0039] Step 1. First, grayscale a color picture with a size of 420 pixels×406 pixels to obtain its grayscale image; then filter the grayscale image with a median filter of a 3×3 template; The image is processed by histogram equalization, that is, the preprocessing of the original image is completed.

[0040] Step 2, calculate the gradient map of the image preprocessed in step 1; then reconstruct the gradient map of the constrained image; finally, divide the reconstructed gradient map through the watershed algorithm to obtain a black and white binary image, that is, complete the Contour extraction of the preprocessed image.

[0041] Step 3, compress the image after the contour extraction in step 2

[0042] 3.1) The length and width of the binarized image obtained in step 2 have dimensions of 420 pixels and 406 pixels respectively, and the side length of the drawing board is 350mm, so the compression ratio of length and width are both 3;

[0043] 3.2) If the size of the compre...

Abstract

The invention discloses an image printing method based on the image processing technology. The image printing method specifically comprises the following steps that first, preprocessing is conducted on an original image; second, contour extraction is conducted on the image preprocessed in the first step; third, the image on which the contour extraction is conducted is compressed; fourth, the compressed image obtained in the third step is printed to a drawing board through a point printing device, and therefore printing and drawing of the original image are achieved. Various image processing technologies are integrated, the image is collected, processed and analyzed, and the processed image is printed out on the drawing board through the point printing device. The image printing method based on the image processing technology can effectively extract the outline of the image. Compared with manual image carving, the image printing method based on the image processing technology greatly shortens time, improves efficiency, achieves liberation of labor, achieves image information collection, processing and analysis, and solves the problem that an existing manual image printing method is low in efficiency.

Description

technical field [0001] The invention belongs to the technical field of image processing and automatic control, and relates to a drawing method based on image processing technology. Background technique [0002] Engraving on stone slabs is one of the typical traditional cultures in China, and line drawing on stone inscriptions is a typical representative. Since the Han Dynasty, it has gradually appeared on epitaphs, door lintels, and column foundations. However, with the continuous development of society and the continuous advancement of science and technology, since the appearance of the world's first printer in 1885, printed matter has rapidly spread to all aspects of the world. Although prints account for most of the decorations, slate paintings still occupy a place in decorations as a work of art, and with the improvement of living standards and spiritual levels, human beings are more and more fond of artistic decorations, usually However, artificial slate painting requi...
