Abstract
The invention relates to an inscription rubbing, in particular to a method for copying an inscription rubbing template by utilizing 3D printing. The method comprises the following steps: converting a picture of the inscription rubbing into a grayscale map; processing the grayscale map to obtain planar three-dimensional vector information data; using a three-dimensional CAD software to process to obtain three-dimensional model data; using a quick forming machine to performing processing and forming on a three-dimensional model; performing object post-processing to obtain the inscription rubbing template; and performing comparison for correction. The method can overcome defects of complex process, low efficiency and high cost in a traditional rubbing template manufacturing process; after the inscription rubbing template is copied, a very important significance for quickly realizing rubbing treatment of a great amount of stone carving and inscription is realized; the inscription rubbing template is convenient to store and spread.
Description
Technical field
The present invention relates to a kind of stone inscription rubbing, refer more particularly to a kind of method of the 3D of utilization print copy stone inscription rubbing template.
Background technology
Stone inscription, general reference is carved stone word or pattern, is one of important carrier of history culture, is non-renewable historical cultural resources.The stone inscription content relates to many aspects such as philosophy, religion, history, geography, economy, politics, military affairs, culture, art, education, science, technology, nationality, has the important function of succession history culture.Stone inscription is that main natural hill is carrier mainly with limestone greatly, is subject to the comprehensive function of nature and human factor in the very long years, and the stone inscription surface is constantly by weathering and residual erosion.Current domestic stone inscription, rubbings are preserved dispersion mostly, form the keeping embarrassment, collect and embarrass, utilize limited situation, loss and damaged degree are quite serious, make historical relic value, historical data value, the realistic price of stone inscription can not get due utilization and better develop.
Rubbing is to use rice paper and prepared Chinese ink, by the word on stone inscription or picture, and a kind of method clearly copied out.Current rubbing completes by craft substantially, and some inscriptions on precipices, on the wall of mountain, is made by hand and generally needed the auxiliary equipment such as setting support, ladder, and make efficiency is low, has certain danger, and the stone inscription in place that can't proping just can't facsimile reproduction.Rubbing has quite bad impact to original looks and the durability of stone inscription.And with the passing of the years, the impaired degree in a lot of stone inscriptions surface is extremely serious.
Summary of the invention
Make the technical problems such as danger, stone inscription that manual operations that the stone inscription rubbing exists and manual operations bring run off and damaged degree is serious, the stone inscription damaged surfaces is serious in order to solve in prior art, the present invention proposes a kind of method of the 3D of utilization print copy stone inscription rubbing template, the method comprises the following steps:
(1) obtain the picture of pending stone inscription rubbing, and to utilize computer be the gray scale picture by picture processing;
(2) utilize software to be edited the gray scale picture, obtain planar trivector information data;
(3) utilize Three-dimensional CAD Software to be processed the trivector information data, make it to become the three-dimensional modeling data that can carry out machine-shaping;
(4) threedimensional model is processed in stone inscription rubbing and the model ratio of 1: 1 by rapidform machine, molded material object;
(5) material object after moulding is gone to support, correction, polishing, deburring, fixing, finally formed stone inscription rubbing template;
(6) utilize the final stone inscription rubbing template construct rubbing formed, contrasted with original rubbing, according to comparing result, the rubbing template is revised.
Further, obtain the picture of pending rubbing in above-mentioned steps (1) with camera.
Further, in above-mentioned steps (4), the forming process of rapidform machine comprises:
(4.1) to the threedimensional model that obtains in step (3) along a direction hierarchy slicing, obtain profile information and the entity information of each thin slice;
(4.2) establish a photosensitive resin groove in rapidform machine, establish a processing table top in the photosensitive resin groove;
(4.3) Ultra-Violet Laser of computer control rapidform machine carries out point by point scanning by minute layer cross section information of stone inscription rubbing three-dimensional data on the photosensitive resin surface, make to be scanned regional thin resin layer and produce photopolymerization reaction and solidify, form a thin layer of stone inscription rubbing;
(4.4) will process the distance that table top moves down a thin layer described in step (4.3), the laser beam spot of computer control rapidform machine is by the described photosensitive resin groove of the individual-layer data point by point scanning of threedimensional model, treating curing photosensitive resin liquid level, described photosensitive resin solidifies after laser beam spot scanning, form second layer aspect on the ground floor aspect, second layer aspect and ground floor aspect are bonded together securely;
(4.5) repeating step (4.4), until whole stone inscription rubbing template construct is complete.
Closer, the distance of an above-mentioned thin layer is between 0.06mm-0.1mm.
The present invention can bring following beneficial effect:
(1) the present invention utilizes advanced digital image processing techniques and 3D printing technique, realized copying stone inscription rubbing template construct, overcome the shortcoming that complex process, efficiency are low and cost is high of traditional rubbing template construct process, after copying stone inscription rubbing template, for the rubbing processing of carrying out fast a large amount of stone inscriptions, rubbings, have very important significance.
(2) the present invention can with very low cost and easily mode will be scattered on all kinds of stone tablets, stone inscription of occurring in nature and be copied, the digitlization stone inscription template generated and the material object that utilizes the 3D printing technique to generate, be convenient to preserve and propagate, utilize advanced technology can in kindly reproduce the stone inscription word.
