Manufacturing method for evaluating and optimizing decorative sheet on basis of image structure similarity

Abstract

A manufacturing method for evaluating and optimizing a decorative sheet on the basis of image structure similarity comprises the following steps that firstly, a special automatic modeling and simulating function battery combination is built in a Rhinoceros+Grasshopper simulation platform, a simulation three-dimensional model of the artistic punched decorative sheet is constructed, rendering is conducted, a simulation effect graph is obtained, and a simulation imaging image is extracted; secondly, the simulation imaging image and an original customized image are converted into gray images; thirdly, geometric transformation and brightness linear transformation are carried out; fourthly, image structure similarity is calculated; fifthly, a structure similarity graph is generated; sixthly, an optimization region is determined; seventhly, contrast enhancement and feature extraction are carried out; eighthly, the feature difference is calculated; ninthly, process information is replaced; tenthly, new machining process information is imported into numerical control machining equipment, and a numerical control punching process is carried out on the decorative sheet. According to the manufacturing method, quality prediction and design optimization of products are effectively achieved, the product optimization efficiency is improved, and the product quality is ensured.

Description

technical field [0001] The invention relates to the technical field of hole decorative plate processing, in particular to a method for manufacturing a decorative plate based on the evaluation and optimization of image structure similarity. 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 numerical control equipment, and the processing process is simple, but complex pre-processing preparations are required to obtain detailed processing data and to write numerical control proc...

However, for quality prediction or quality pre-evaluation, the quality of the final product is only evaluated manually. If the quality meets the requirements, the design will be completed. If it does not meet the requirements, it will be redesigned according to the product imaging characteristics and deviation characteristics.

However, there is no unified quality evaluation standard and optimization method, and no quality prediction or design optimization plan for this product has been made public.

It is easy to lead to the low imaging effect of the product due to unreasonable design (not suitable for the customized image type), which will increase the production risk and customization cost, and the uncontrollable quality will lead to the extension of the customized production cycle, which is not conducive to Customized production and manufacturing of artistic punching plates

At the same time, there is no reasonable optimization process that leads to the design and manufacture of existing products. If the product is not up to standard, it cannot be modified on the basis of the original design. The original design is invalid and needs to be redesigned, which increases the design time cost and labor cost. low efficiency
