A method for manufacturing artistic punching decorative panels based on feature-based hole layout design

Abstract

The invention discloses a method for manufacturing an artistic punched decorative plate by adopting characteristic-based hole layout design. The method comprises the following steps of (1) importing a color custom image of a hole decorative plate to a system and converting the color custom image into a grayscale image; (2) performing characteristic segmentation on the grayscale image; (3) performing characteristic inner hole layout: performing characteristic locating and characteristic classification, and selecting and using a layout method for different holes according to classification of characteristics; (4) performing boundary hole layout: performing characteristic reconstruction, cutting a characteristic boundary region, and performing characteristic boundary layout; (5) integrating process information to generate complete manufacturing process information of the artistic punched decorative plate; and (6) importing the manufacturing process information to a numerical control machining equipment system for performing a numerical control punching machining process on the artistic punched decorative plate. Variable-direction, variable-spacing, variable-density and variable-aperture multiple variable combination hole layout modes are realized; the imaging quality and the imaging effect are improved; and the imaging capability and the product quality of the hole decorative plate are optimized.

Description

technical field [0001] The invention relates to the technical field of hole decorative plate processing, in particular to a method for manufacturing an artistic punching decorative plate based on feature-based hole arrangement design. Background technique [0002] Art punching decorative plate is a new type of decorative aluminum plate product. It realizes the "photographic" or "graphical" effect by using the contrast effect between holes and the background, hollowing out differences, etc., and simulates the pixel distribution with holes, so that the decorative board has a stronger artistic effect, strong customizability, and style It is more exquisite and is often used for the decoration of large public places or large buildings such as subways and airports. It can be processed by CNC equipment, and the processing process is simple, but complex pre-processing preparations are required to obtain detailed processing data for writing CNC processing programs. In the past, the...

Problems solved by technology

[0003] Although there are public integrated solutions for art punching decorative plate hole design about reading images and generating processing technology information, there are still many deficiencies. The usual arrangement methods are equal spacing, equal density, and fixed direction. The hole layout design method with variable aperture has fewer variables, and at the same time, it is limited by too few aperture types, few combination styles, weak ability to express image detail features, blurred and distorted imaging effects, and weak imaging ability, which greatly inhibits artistic impact. Improvement of the quality and added value of hole decorative panels
