Method for engraving calligraphies and paintings on carriers by laser on basis of three-dimensional curved surfaces

Abstract

The invention discloses a method for engraving calligraphies and paintings on carriers by laser on the basis of three-dimensional curved surfaces. The method comprises the following steps: (1) designing a three-dimensional overall curved surface object; (2) attaching bitmap or vector diagram calligraphies and paintings on the three-dimensional curved surfaces to generate an overall three-dimensional calligraphy and painting mathematics model; (3) uniformly dividing the three-dimensional overall curved surface object into a plurality of pieces, and carrying out injection molding or pressing into transparent plastic parts; (4) uniformly spraying paint on the transparent plastic parts; (5) dividing the overall three-dimensional calligraphy and painting mathematics model into a plurality of pieces, and engraving the pieces of the three-dimensional calligraphy and painting mathematics models on the corresponding plastic curved surfaces by laser; (6) splicing the engraved transparent plastic parts together; (7) mounting an LED lamp in each transparent plastic part; and (8) forming the calligraphies and paintings which take the three-dimensional curved surfaces as the carriers. The calligraphies and paintings are clear in line and high in contrast ratio, cannot fade easily, are three-dimensional, dynamic and lifelike, not only can illuminate at night, but also can be blended into darkness to show spectacular sights.

Description

technical field [0001] The invention relates to a method for laser engraving calligraphy and painting, in particular to a method based on laser engraving calligraphy and painting on a three-dimensional curved surface carrier. Background technique [0002] Calligraphy and painting are the spiritual wealth of human culture and art. Most of them are drawn on paper and displayed in front of the audience in the form of a flat carrier. If people, animals, landscapes, and writing characters can be drawn on a three-dimensional curved surface with undulating characteristics, it will be more three-dimensional and ornamental. However, it is very difficult to write characters or draw pictures on such curved surfaces manually. Contents of the invention [0003] The purpose of the present invention is to provide a three-dimensional curved surface as a carrier, paste the calligraphy and painting expressed in bitmap or vector diagram on the three-dimensional curved surface through compute...
