Embodiment Construction

[0045] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0046] The present invention provides a character recognition method, referring to figure 1 , in one embodiment, the character recognition method includes:

[0047] Step S101, acquiring the handwriting data of the stylus when writing;

[0048] In this embodiment, the stylus has a built-in acceleration sensor. The acceleration sensor can be, for example, a three-axis gyroscope. When the stylus is writing, the acceleration sensor can sense its acceleration in the three-axis direction. The acceleration value can be analyzed to obtain the trajectory of the nib of the stylus when writing, and the trajectory of the nib can be recorded, and the trajectory of the nib can be used as the handwriting data of this embodiment.

[0049] Step S102, extracting digital feature information of each character according to the handwriti...

Abstract

The present invention discloses a character recognition method and a stylus. The character recognition method comprises the following steps of: acquiring handwriting data of the stylus in the writing process; according to the handwriting data, extracting numerical characteristic information of each character; and acquiring standard characteristic information of pre-stored characters, and according to the standard characteristic information, recognizing characters corresponding to the extracted numerical characteristic information of each character. According to the character recognition method and the stylus, electronization of paper documents can be implemented; long-term storage of written contents is facilitated and subsequent inquiry is convenient; the written contents are not required to input into intelligent terminals such as a computer and the like in a manual mode, so that input workload is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of character recognition, in particular to a character recognition method and a stylus. Background technique [0002] In daily life or work, in many occasions such as examination rooms or conference sites, users generally rely on the stylus to write and record on paper documents, but paper documents have a certain period of storage, which is not conducive to long-term storage. There is a lot of inconvenience in the process. If the recorded information is entered into a smart terminal such as a computer, it needs to be manually entered one by one, which leads to low efficiency and heavy workload. [0003] The above content is only used to assist in understanding the technical solution of the present invention, and does not mean that the above content is admitted as prior art. Contents of the invention [0004] The main purpose of the present invention is to provide a character recognition method and a sty...
