Embodiment Construction

[0050] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0051] The present invention improves the original digital electronic pen, adding different colors, different stroke widths and different pen-lifting time intervals and other functional control and display devices, so as to obtain stroke (x, y) coordinate data related to handwritten Chinese and sketches One-to-one data combination of different colors, different stroke widths and different pen-up time intervals. On this basis, use these data combinations to segment Chinese characters and sketch graphics, confirm the number of strokes and extract Chinese characters. In the process of Chinese character extraction, the number of multi-level strokes is used as the first symbol. In the case of the same number of multi-level strokes and strokes, ...

Abstract

The invention discloses a handwritten text and graphic recognition system based on a paper medium. The handwritten text and graphic recognition system comprises a digital handwriting pen and a nano gridded touchpad, wherein the digital handwriting pen consists of a pen tip, a pressure sensor, a distance-measuring sensor, a data acquisition module, a storage, a battery, a color selection switch, a time-interval selection switch and a stroke-width selection switch; the gridded touchpad is formed by nano gridded microholes in a nano interval, and a pressure sensor is arranged under the microholes of the touchpad; the amounts of water and ink in the microholes are measured by the pressure sensor; and by the obtained storage amounts of the ink and the water added on each coordinate point, Chinese characters are recognized, and the profile of an ink painting is calculated to obtain accurate characters or the ink painting. The handwritten text and graphic recognition system disclosed by the invention has the advantages that direct connection with a computer is not needed, and an electronic document with Chinese characters or pictures can be formed on plain paper by handwriting.

Description

technical field [0001] The invention relates to information technology, in particular to a recognition device and a recognition method for inputting text and graphic information with a digital electronic pen. Background technique [0002] At present, the digital handwriting pen industry is developing faster and faster. With the rapid growth of the number of netizens, digital handwriting pens are also very popular among netizens. With a digital stylus, you can send handwritten emails, and you can communicate easily. At the same time, you can avoid the tedious typing of the keyboard and the inconvenience of using the mouse for a long time, making the Internet easier and more natural. The digital stylus has become a good helper for surfing the Internet. China's handwriting digital pen has a very large market space. [0003] At present, the research and development of domestic handwritten digital pens has not been out of line, which has led to the failure of the scope and effic...
