Computer virtual sculpturing method for calligraphy Chinese characters

Abstract

The invention discloses a computer virtual sculpturing method for calligraphy Chinese characters. The method comprises the following steps of: binarizing the original image of a two-dimensional calligraphy work, extracting the font characteristic information of the calligraphy Chinese characters, and constructing a point light source boundary for all Chinese characters in the calligraphy work; calculating the initial depth map of the calligraphy Chinese characters based on an illumination attenuation model; obtaining the stroke vigor distribution information of the calligraphy Chinese characters according to the gray value of the image of the calligraphy Chinese characters, and calculating a depth weight matrix; optimizing the initial depth map of the calligraphy Chinese characters by use of the depth weight matrix so as to construct a triangular patch; and rendering to generate a three-dimensional virtual sculpture product of the calligraphy Chinese characters. Through the invention, a virtual sculpture product of calligraphy Chinese characters with natural depth change and smooth transition of the stoke cross part can be generated; and as the writing power factor is considered in the process of calculating the pixel point depth of the calligraphy Chinese characters, the vitality of the virtual sculpture product of the calligraphy Chinese characters is enhanced. The method disclosed by the invention can be applied to the fields of virtual reality, computer-aided manufacturing and the like.

Description

technical field [0001] The invention relates to computer graphics, image processing and virtual reality, in particular to the generation of three-dimensional Chinese characters, in particular to a computer virtual engraving method for calligraphy Chinese characters. Background technique [0002] The relationship between Chinese calligraphy and sculpture has a long history and is connected by blood. Calligraphy is the spirit, and sculpture is the form. Calligraphy works of Chinese characters carry the beauty of the shape and structure of Chinese characters in a static way, while carving works of calligraphy and Chinese characters fully demonstrate the movement and strength of calligraphy lines with their special artistic expression. The combination of various stele inscriptions, statues and stone carvings The works of art show the unique style of Chinese plastic arts. With the development and progress of the times, people hope that Chinese history and culture can be integrat...

Problems solved by technology

However, how to obtain information on the distribution of brush strokes at the time of initial creation based on existing calligraphy works is still blank in this area.

[0005] In addition, current computer-aided engraving equipment is only suitable for processing computer-generated Chinese characters, while handwritten calligraphy Chinese characters can only be engraved by hand
