Problems solved by technology

However, through the machine learning method, due to the influence of GPU and computer memory, we cannot predict the color of the entire tile. We must cut the tile into fixed-size blocks for processing, and then splice the cut pieces into a complete tile. image, but it can be clearly seen that there are certain gaps in the spliced ​​image

Embodiment Construction

[0041] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0042] In a preferred embodiment of the present invention, a method for converting a three-dimensional tile printing file that eliminates seams is provided, and its function is to convert the color separation image designed by the tile designer into a halftone image that can be recognized by the tile printer , where the color separation image is converted into blocks and then reassembled and restored to form a halftone image in the printed file. see figure 1 As shown, the basic process of the conversion method includes the basic process including expansion, cutting, model prediction, splicing and rounding operations, and the specific steps are as follows:

[0043] S1: Extend the margins of the upper, lower, left, and right sides of the N*N original color separation image to be converted into a halftone image, and obtain an extende...

Abstract

The invention discloses a three-dimensional ceramic tile printing file conversion method and device capable of eliminating abutted seams and a medium, and belongs to the field of image data format conversion. Aiming at the problem of abutted seam elimination in a three-dimensional tile printing file, the invention provides a mode of combining deep learning and tradition to convert a color separation image into a halftone image, so that the conversion from the color separation image to the halftone image can be quickly and accurately realized, compared with a traditional conversion method, the processing speed and efficiency are obviously improved. Moreover, processing of splicing gaps is considered in the conversion process, so that when the color separation image designed by a designer is converted into the halftone image of the 3D printer, the situation that seams exist is avoided, and printing pattern flaws are reduced.

Description

technical field [0001] The invention aims at the application field of image data format conversion, especially the image format conversion method in three-dimensional ceramic tile printing files. Background technique [0002] With the upgrading of production technology, 3D printing technology has gained more and more attention, and has become a research hotspot in various production technology fields. 3D printing technology refers to the technology of generating three-dimensional solids by adding materials layer by layer through continuous physical layer superposition. The existing 3D effect of tiles is mainly to achieve a visual three-dimensional or uneven decorative effect on the surface of ceramic tiles, rather than forming the main structure through layer-by-layer printing of 3D technology. Due to the limitation of ceramic tile raw materials, it is not easy to decorate its surface, so the research of 3D printing technology in the field of ceramic tile production is very...
