Embodiment Construction
[0029] The device of the present invention includes an interactive unit, an operation processing unit and a storage unit, wherein the interactive unit collects text images or videos that need to be identified, receives and displays relevant information on operations such as user clicks and selections, and converts the received user input information Send to the operation processing unit, and receive and display information from the operation processing unit, including the image acquisition unit, display unit and user input detection unit; the operation processing unit is for the text image input from the interaction unit and the user input information, and the text area Detecting and locating, and recognizing characters in a text area, including a text detection and positioning unit and a text recognition unit, wherein a text area refers to a circumscribed rectangular area containing one or more text blocks.
[0030] The image acquisition unit is to collect the text image or vi...

The invention relates to an OCR recognition method with an auxiliary positioning function. The method comprises the following steps: shooting a target and capturing an image containing characters; searching areas of the image and detecting out one or more text areas; selecting a specific text area; and recognizing characters in the selected specific text area. By using the method and a device of the invention, a user can automatically obtain the text areas in the image, and obtain the interested text areas in an interactive mode so as to carry out applications such as character recognition, translation, and the like. The invention can be applied to ordinary character scenes such as the automatic recognition and the translation of guideboards, public notices, newspaper, and the like, and is particularly suitable for a mobile terminal with the function of a camera. The invention can facilitate the use of the user without complicated auxiliary operations and interactions, reduces the searching range of the image, automatically obtains the text areas interested by the users, reduces the calculating operation time of a system and can improve the accuracy rate of positioning.
Description
technical field [0001] The invention relates to the fields of image processing and pattern recognition, especially text detection and positioning in video and natural scenes, and character recognition. Background technique [0002] OCR technology is now more and more applied to devices such as mobile smart terminals and PDAs with image scanning (or camera) functions. However, when the background is often complex such as video images, there are still problems in the text positioning before OCR. Due to certain technical difficulties, the results of text positioning are deviated, and the characters to be recognized cannot be detected conveniently and accurately, or a text area is mistakenly divided into multiple related text sub-areas, which affects the continuity of OCR recognition results. And calculation overhead, coupled with the low text recognition rate, resulting in unsatisfactory final results (such as translation), so at this time, some auxiliary positioning methods ar...
