Problems solved by technology

[0003] The patent for duplicating oil paintings by screen printing "Method for making Fangzhen oil paintings by screen printing on a screen" (1997), publication number: CN 1155479A, proposes to use adhesive to fix the fabric on the positioning plate, and then use screen printing method to make simulated oil paintings, but this method can only roughly realize the surface undulations of the copied oil paintings
The patent "a new process for duplicating oil painting" (1999) by inkjet printer printing oil painting, publication number CN 1236711A, proposes to use inkjet printer to print the color scan copy of the original oil painting, but this method cannot reproduce the surface pigment of the original oil painting altitude information
Through the pretreatment of the canvas, the patent "A Method for Making Oil Painting with a Stereoscopic Surface" (2013), publication number CN103332095A, paints with oil paints on the canvas with the three-dimensional information processed manually, but the reproduction efficiency and effect of this method can not meet the requirements
By directly using a UV printer to print ink layer by layer, the patent "A Method for Using a UV-LED Inkjet Printer to Realize the Stereoscopic Replication of Oil Painting" (2015), the patent for reproducing the height information of the original oil painting, publication number CN105128589A, compared to the above several A method for copying oil paintings, this method has been greatly improved, and can better copy the height and color information of oil paintings (layering accuracy of 100 microns), but this method has a lack of accuracy for color and height copying
[0004] To sum up, digital printing technology can realize two-dimensional plane printing of oil paintings, which can restore the color to a high degree, but still cannot restore the pigment thickness of the original painting; silk screen printing and pigment thickness compensation can partially restore the pigment thickness, but Insufficient reduction and inefficient

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, and the present invention includes but not limited to the following embodiments.

[0015] Such as figure 1 As shown, the present invention provides a kind of oil painting 3D duplication method using UV inkjet printer and 3D printer, and its specific implementation process is as follows:

[0016] 1. Select an original oil painting to be copied, with a size of 2500mm*2500mm, and fix it flat on the control panel to control the flattening error of the oil painting. The control panel is placed flat in a well-lit room. In order to reduce the lens distortion, the CCD lens used to scan the image information of the original oil painting is firstly corrected by Zhang Zhengyou calibration method, so as to improve the accuracy of the subsequent reverse modeling of photography.

[0017] Use the corrected CCD lens to scan and shoot the original oil painting placed in ...

Abstract

The invention provides an oil painting 3D copying method adopting a UV ink-jet printer and a 3D printer. A digital photography measuring method is used for carrying out 3D modeling on the original painting of an oil painting, the 3D printing technology is utilized for copying printing, and the pigment thickness information of the original copy of the oil painting is copied precisely; and then color information is printed through the high-precision color printing technology of the UV ink-jet printer, high-precision copying of the three-dimensional information and color information of the oil painting is completed, and an oil painting stereo is obtained. By means of the oil painting 3D copying method, on the premise of guaranteeing that the manuscript of the oil painting is free of damage and free of physical contact, the oil painting is copied simply and fast, and the obtained stereo has higher fidelity and precision.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional reproduction of oil paintings, and in particular relates to a method for 3D reproduction of oil paintings using a UV inkjet printer and a 3D printer. Background technique [0002] With the development of computer vision technology and the continuous improvement of people's consumption level and aesthetic level, there are better solutions and higher requirements for the reproduction and digital storage of classic oil paintings. The reproduction technology of oil painting mainly uses 3D printers and color printers to carry out three-dimensional digitization and three-dimensional reproduction of oil paintings based on three-dimensional reconstruction technology, so as to realize high-fidelity reproduction of oil paintings in terms of pigment thickness and color. [0003] The patent for duplicating oil paintings by screen printing "Method for making Fangzhen oil paintings by screen printing ...
