Description

Calligraphy digitization system under natural interactive interface and method of using the system to realize real-time writing of calligraphy

technical field

The invention belongs to the research field of calligraphy digitization, and relates to a calligraphy digitization system under a natural interactive interface and a method for using the system to write calligraphy in real time.

Background technique

The natural interactive digital calligraphy system integrates high-tech means such as image capture technology, image processing technology, multi-touch technology, naturalized human-computer interaction technology, gesture recognition technology, multimedia technology, data acquisition and processing technology, and lighting technology. The device creates a writing environment in which calligraphy images and strokes overlap, enabling the operator to have a real-time writing space where they can abbreviate as they see it.

In the existing calligraphy digitization system, the focus is on digitally simulating the art of calligraphy through computer technology, through research on the brush structure and ink diffusion, and then digitally simulating the handwriting of calligraphy art. While this process is a good representation of the art of calligraphy, there are also two shortcomings: First, in terms of system interactivity, existing research and technologies have the disadvantages of weak interactivity and unnatural interaction. Complete the digital creation of calligraphy in the daily writing state. In addition, in terms of calligraphy handwriting performance, digital simulation cannot reflect the real writing state of calligraphy, and the various forms of writing brushes cannot be represented by simulation.

Contents of the invention

In order to solve the application of natural interaction technology in calligraphy digitization, the present invention provides a new type of calligraphy digitization system under the natural interaction interface because the existing digitized calligraphy system has the disadvantages of weak interaction and unrealistic handwriting. Calligraphy creation is carried out in a daily writing state under the natural interactive interface, and the calligraphy handwriting can also be truly displayed. At the same time, the invention can also be used as a display system to spread the writing process of calligraphers in real time.

The purpose of the present invention is achieved through the following technical solutions:

A calligraphy digitization system under a natural interactive interface, including three parts: an input system, a central processing system and an output system, in which:

The input system includes a desk, a light box, a writing brush, an inkstone, a DC light tube and a high-definition camera. The upper surface of the desk is a transparent glass plate for placing the light box, writing brush and inkstone. The bottom of the light box is a translucent plate. Its side wall is equipped with a DC light tube to provide a shadowless light source; a high-definition camera is placed under the desk to collect image information of brushes and fingers above the translucent board, and is connected to the central processing system;

The central processing system is used to identify the image information of brushes and fingers input by the camera in the input system, process the brushes and user operation input information, and generate writing images to be sent to the output system;

The output system is a projector, and according to the writing image imported from the central processing system, it is projected onto the translucent plate of the light box of the input system through the projector, so as to realize the real-time display of calligraphy creation.

In the above system, the light box is a square light box with a translucent plate at the bottom, and four DC light tubes of the same power are connected in parallel on its four walls.

In the above system, the central processing system is a tablet computer or a PC.

A method for realizing real-time writing of calligraphy by using the above-mentioned system. The user inputs brush brushes and finger touch information images through the camera to the central processing system through the input system, and the central processing system receives the images and records the writing brush information and gestures. The information is extracted and processed separately, and the generated feedback image is output. After that, the output system presents the completed brush and interface image on the writing desktop, and adjusts the image information to correspond to the user's writing behavior, thus forming a A real-time interactive environment that sees and writes.

The invention digitally creates traditional calligraphy art, uses a camera to obtain brush shape and gesture point information, and uses technologies such as multi-touch and image recognition processing to enable people to complete calligraphy in a daily state under a natural interactive interface. Digital writing. This system provides a new digital idea for the art of calligraphy. While users write in a state of natural interaction, they also record the real handwriting of calligraphy. By recording the handwriting and gesture image information of the writer, it is transmitted to the computer for image recognition and processing, and at the same time, the handwriting information and gesture commands processed by the computer are fed back to the writer through equipment such as a projector, thus achieving a natural interaction status. The invention can be applied to the fields of calligraphy art teaching, daily writing and digital display.

Detailed ways

In order to clarify the characteristics and working principles of the present invention more clearly, the present invention will be described below in conjunction with the accompanying drawings and embodiments.

This embodiment provides an interactive projection psychological sand table game system, as shown in Figure 1, including: an input system, a central processing system and an output system, wherein:

The input system includes a desk, a light box, a brush, an inkstone, a DC light tube and a high-definition camera. The surface of the desk is transparent. DC light tube, and the surface close to the desk is made of translucent material, which is used to present the output image of the output system. Brushes and inkstones can be placed on both sides of the light box. Finally, the choice of camera, according to the type of light box lamp, DC fluorescent lamp The tube corresponds to an ordinary high-definition camera or a DC infrared lamp and an infrared high-definition camera. Users can combine the design status to input brush and finger touch information.

The central processing system is a tablet computer or a PC, which processes and recognizes the incoming image from the camera of the input system. The specific performance is: it is used to identify the image information of the brush and the finger from the camera in the input system, and the brush and the user Manipulate the input information for processing, and generate written images to be sent to the output system;

The output system mainly includes projectors, monitors and other equipment. According to the writing image imported from the central processing system, it is projected onto the translucent plate of the light box of the input system through a projector to realize real-time display of calligraphy creation.
