Description
Technical field
The invention belongs to the character recognition method and device of field of computer technology, more particularly to a kind of dictionary pen.
Background technology
Students need to only use dictionary pen to sweep word and sweep, and just can obtain pronunciation, lexical or textual analysis and translation of the word etc.
Information, without repeatedly going to thumb dictionary book, also need not every time go to school and carry heavy dictionary book, it is seen that the appearance of dictionary pen
It is a big Gospel of student group.
At present, most dictionary pen is all only limited to the bookish print hand writing of identification printing, and in daily life,
Hand-written contribution or material (the prescription list that such as doctor outputs) or relatively common, the also often appearance one on printing books
The manuscript of a little writers, is changed greatly due to handwritten text, great personal style, and the difference of print hand writing is larger, only limits
Handwritten text can not be recognized well in the dictionary pen of identification print hand writing.
The content of the invention
It is an object of the invention to provide the character recognition method and device of a kind of dictionary pen, it is intended to solves due to existing skill
Art can not provide a kind of character recognition method of effective dictionary pen so that dictionary pen is generally only used for recognizing print hand writing,
And the problem of preferably can not recognize handwritten text.
On the one hand, the invention provides a kind of character recognition method of dictionary pen, methods described comprises the steps：
When receiving the scan command of user, word to be identified is obtained by default scanning end；
According to default handwriting font object library and printing general font storehouse, the word to be identified is identified；
According to the corresponding recognition result of the word to be identified, the word to be identified is obtained in default dictionary
Text information, the text information of word to be identified described in display output.
On the other hand, the invention provides a kind of character recognition device of dictionary pen, described device includes：
Scan module, for when receiving the scan command of user, word to be identified to be obtained by default scanning end；
Identification module, for according to default handwriting font object library and printing general font storehouse, entering to the word to be identified
Row identification；And
Output module is inquired about, for according to the corresponding recognition result of the word to be identified, being obtained in default dictionary
The text information of the word to be identified is taken, the text information of word to be identified described in display output.
The present invention is when receiving the scan command of user, by default scanning end acquisition word to be identified, and according to
Default handwriting font object library and printing general font storehouse, word to be identified are identified, after recognition result is obtained, according to knowledge
Other result obtains the text information of word to be identified, last display output text information, so that logical in default dictionary
Cross and increase handwriting font object library and printing general font storehouse on dictionary pen, realize the upper handwritten text of dictionary pen and print general
The identification of font file, is effectively improved the Text region rate of dictionary pen.
