Abstract

The present invention discloses a method for making optical character recognition by using display operation terminal. Said method includes the following steps: firstly, obtaining image having need of making optical character recognition and displaying it on the display device of display operation terminal; analyzing contents of said image and separating its literal contents into several literal region blocks; then selecting literal region block having need of making optical character recognition on the display operation terminal; finally, making optical character recognition. Said literal region block can be limited and displayed by adopting identification character.

Description

technical field

[0001] The invention relates to a method for a display operation terminal to automatically recognize text characters in an image, in particular to a method for a display operation terminal to perform optical character recognition. technical background

[0002] Existing business card recognition systems or optical character recognition systems (whether used on mobile communication terminals or on computers) perform optical character recognition methods, generally first using image capture equipment to obtain images, such as using The camera scans the image, scans the image with a scanner on the computer, or directly obtains network downloads, pictures, etc., and then uses optical character recognition software or hardware to recognize and output all the characters in the image, so the system processing speed is quite slow. Moreover, the operator is disturbed by many irrelevant text information that is not of interest to the operator while obtaining the output ...

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] refer to figure 1 , A method for performing optical character recognition on a display operation terminal provided by the present invention can be applied to products such as computers, mobile phones, and PDAs to identify text information on advertisement boards, license plate numbers, and communication information on business cards. Its essence is to combine the operation-assisted positioning of the display operation terminal with the algorithm of the optical character recognition system. It specifically includes the following steps:

[0024] Step 1, obtaining an image to be subjected to optical character recognition, and displaying it on a display of a display operation terminal.

[0025] For example, a computer can obtain an image for OCR through a scanner, a digital camera or other means, and a mobile communication termin...
