Calligraphic handwriting presentation method based on optical principle

Abstract

The invention provides a calligraphic handwriting presentation method based on an optical principle. The method comprises the following steps: acquiring a brush stroke image drawn on a handwriting board by a user through a writing brush, wherein the handwriting board is a light transmission board; arranging a light source in the corresponding position of the handwriting board based on a mode of generating the image on the handwriting board to form the image on the surface of contact between the writing brush and the handwriting board; sending the acquired brush stroke image to an image processing device by a photoelectric image sensor; collecting the brush stroke image in real time by the image processing device, processing the collected brush stroke image, extracting brush stroke shape profile data, drawing the brush stroke shape profile data on canvas, filling the drawn brush stroke shape profile with color, forming a calligraphic handwriting by the continuously drawn color-filled brush stroke shape profile, and presenting the canvas on a display device. Through the method, a conventional writing brush can still be used by the user, the image on the canvas is relatively close to the simulation effect of the image really drawn by the user, and the hardware requirement is relatively low.

Description

technical field [0001] The invention relates to the field of digital image processing, in particular to a calligraphy handwriting presentation method based on optical principles. Background technique [0002] With the advancement of modern technology, the popularization of computers and the rapid development of related technologies, people have a new way of calligraphy creation. Traditional pens, inks, paper, and inkstones are no longer necessary tools for writing. In most cases, people carry out text input work by means of keyboard and mouse. Therefore, on the basis of drawing on the traditional calligraphy art, in order to inherit, promote and develop the calligraphy art, its scientific simulation has become one of the most challenging topics in the field of art and technology. At the same time, calligraphy beginners need to do a lot of copying training on many excellent calligraphy works to learn the knowledge and skills of calligraphy brush, structure, composition and ...

AI Technical Summary

Problems solved by technology

However, general software simulation algorithms consume a lot of computer resources, especially software algorithms that use 3D, dynamic deformation and other technologies to simulate brushes require a large number of iterative floating-point operations, which requires a very high configuration of the computer, and the simulation effect is not ideal.

[0004] The inventor found in the research that the way of software simulation calligraphy in the prior art has the problem of high requirements on hardware (such as computer) configuration and unsatisfactory simulation effect
