Problems solved by technology

[0003] As a traditional writing tool, the pen is the most familiar writing tool for people, but there are also many inconveniences in the information age, especially after taking notes, it is impossible to convert it into electronic text for dissemination at the first convenient time
And as a writer or scientist, the original manuscript is very important information, and because the traditional original manuscript is only one and easily damaged, the traditional manuscript is very precious and easy to be damaged and lost

Embodiment Construction

[0029] The method for identifying electronic manuscripts of the present invention divides the overall circuit into a trigger circuit, a recognition processing circuit, and an infrared camera; The infrared camera is located on the glasses.

[0030] Step 10. When starting to work, the trigger circuit heats up the pen tip, making the temperature of the pen tip significantly higher than the ambient temperature; when the pen tip touches an object, the effective contact information is sent to the infrared camera through wireless transmission;

[0031] Step 20, after the infrared camera receives the effective contact information, it shoots continuous infrared video images, and sends them to the identification processing circuit to correct the infrared video images in turn;

[0032] Step 30, the recognition processing circuit records the position of the pen tip in each frame of image in the infrared video after correction, and converts the position into two-dimensional coordinates for...

Abstract

The invention provides a method and device for identifying electronic manuscripts. The trigger circuit makes the nib heat, so that the temperature of the nib is significantly higher than the ambient temperature; when the nib touches an object, the effective contact information is sent to the infrared camera through wireless transmission; The infrared video image is sent to the recognition processing circuit to correct the infrared video image in turn and record the position of the pen tip in each frame of the infrared video image after correction, and then convert it into two-dimensional coordinates for recording; complete the contact at the pen tip Afterwards, the infrared camera stops shooting, and the recognition processing circuit linearly connects the nib coordinate points of all image frames in this contact process according to the sequence of image acquisition to form a manuscript handwriting image and stores it, and simultaneously performs text recognition processing and caches it. The invention can combine the image character recognition technology and the writing tool to record the original manuscript and transform the electronic characters while writing.

Description

【Technical field】 [0001] The invention relates to a character recognition and processing technology in an OCR image, in particular to a recognition method and device for an electronic manuscript. 【Background technique】 [0002] OCR (optical character recognition) is an image character recognition technology that uses a computer to extract the text in a picture imported by a scanner or a digital camera, and displays the text information on the original picture in the form of text, which is convenient for everyone to edit and copy. Many enterprises, institutions, and government agencies have chosen Quick OCR text recognition, because it can scan a large number of books into the computer and convert them into text documents. Jiesu OCR is characterized by high speed and high efficiency. It is a top-notch text recognition technology. The recognition rate of printed manuscripts is as high as 99.5%. Text is an ideal text, form, and image entry system. [0003] As a traditional wr...
