A Projection Interactive Calligraphy Practice System and Its Implementation Method

Abstract

The invention relates to a projection interaction calligraphy practice system and an implementation method thereof. The system comprises a camera, a double-camera control module, an LED (Light Emitting Diode) infrared light-supplementing lamp, a data storage module, an image data analysis module, a central processing unit, a software operation module, a display control module, a projection module, a power supply and a power supply control module. The implementation method comprises the following steps: firstly, initializing system coordinates; under the condition that visible light filters exist in front of the camera and the LED infrared light-supplementing lamp, controlling the projection module to project a control menu provided by the software operation module on a plane by the display control module, and meanwhile controlling the camera to capture a gesture action image within the projection plane in real time and performing corresponding gesture control according to the gesture action image by the camera control module; controlling the projection module to project writing animation of characters to be practiced by a user on a calligraphy practice region by the display control module; taking a picture of characters written by the user, and making a judgment. According to the system and the method, movement ink marks of practice characters are dynamically projected onto paper, so that a writer can clearly and visually view a writing way and performing following writing practice on the paper with a real writing brush.

Description

technical field [0001] The invention relates to projection technology, image capture and analysis technology, infrared technology, and gesture control technology, and belongs to the field of interactive projection systems, in particular to a projection interactive calligraphy practice system and its implementation method. Background technique [0002] Now when people are learning calligraphy, in addition to face-to-face teaching by calligraphy teachers, there is also learning with the help of books, copybooks and video auxiliary materials. But these calligraphy training methods have following shortcoming: [0003] 1. When people listen to the calligraphy teacher's face-to-face lecture and copy the copybook, they should first look up or turn their heads to look at the copybook, remember the font and writing essentials, and then turn back to write. This kind of instant memory will cause the written characters to be copied. The words will be biased. [0004] 2. When studying ...

Problems solved by technology

[0003] 1. When people listen to the calligraphy teacher's face-to-face lectures and copy the copybooks, they should first look up or turn their heads to look at the copybooks, remember the fonts and writing essentials, and then turn back to write. Such instant memory will cause the written characters to be copied. The word will have deviation

[0004] 2. When studying with the teacher or watching videos, the teacher's pen posture can only be observed and imitated from a single shooting angle, and cannot be observed in a 360-degree manner

But these can only be practice frame structures, and cannot have the feeling of writing on paper with a hard pen or brush

[0006] 4. When doing writing training, there are no quantitative indicators for the strength of the strokes, the rhythm of the brush, etc., and you can only rely on imitation and comprehension by yourself, so learning calligraphy is not efficient

If the teacher is not on the scene or can't judge in time, then the next person will make the same mistake when writing the same word, so it will cause twice the result and half the result
