Abstract
The invention relates to a character extracting method based on the camera and the character identification technique, specifically relates to a method for character extraction using the text image shot by the camera, belonging to the technical field of the character input using the computer to combining the character identification technique. A program for controlling and commanding the CPU to execute the following operations is stored in the storage of the intelligent device having the text image analysis and character identifying function: affirming the users to select the interesting word area in the accustomed selecting way on the display of the intelligent device for showing the interface of the text image; analyzing and character identifying the character image in the selected area, commanding the display to show the identification result, reversing the identification result, completing the text extracting. The method has the advantage that the users can select the interesting character on the text image in the accustomed selecting way, thereby completing the text extracting.
Description
Technical field
The present invention relates to a kind of literal extracts method, definitely say, relate to the method that a kind of text image of taking with camera carries out the literal extracts, belong to the technical field of carrying out the literal input with camera in conjunction with character recognition technology based on camera and character recognition technology.
Background technology
In recent years, along with the application of camera on smart mobile phone and microcomputer is more and more, the application of carrying out the literal input in conjunction with character recognition technology based on the text image of taking with camera also more and more widely, as name card recognition technique based on camera, text image analysis and recognition technology etc.One of important use is exactly the literal extracts: the user sees passage at newspapers and periodicals or other places, perhaps a few words wherein, very interested, want to take passages, preserve for share in the future or with friend, he just can take these literal with camera, discerns and put in order interested those literal with character recognition technology from the text image that camera is taken then.
At present such software that utilizes camera to carry out the literal extracts has had the function as " the Chinese king extracts " software in the N800 of the Amoisonic mobile phone just has.The user utilizes this software can select to allow software analyze the text image that camera is taken automatically, and identify wherein literal, also can select to allow the automatic analysis user of software drawing certain the selected specific literal section of frame or other modes or the text image of literal line, and identify literal wherein.
Utilize existing software, the user can obtain: the identification literal of whole section text image; The identification literal of one full line text image; Identification literal with the regional interior text image of choosing with red rectangle frame.To obtain the identification literal of the text image of the inter-bank that red line marks such as the user, he/her have to utilize earlier software to obtain identifying to contain the identification literal of text image of the two style of writing words of the words, recycle other the text edit tool and do the operation that butt truncates, just can obtain the literal in the words at last.
In actual life, people get used to selecting interested literal with following dual mode:
One of mode is on the paper media such as books, newspapers and magazines, draws a line at interested sentence place with pen, and this line can be straight, curved, or even ripple, can draw on word, also can draw below word.
When two of mode was to use edit tool such as microsoft word or reads electronic document with browsers such as internet explore, the user can choose interested sentence by mouse-based operation easily.To select one or several sentences of inter-bank such as the user, the left button that only need to pin mouse moves to the final position of choosing sentence to mouse from the original position of choosing sentence just passable, the path independence that selection and mouse move, mouse also needn't inswept all sentences of choosing, and the literal that edit tool or browser can be found out between original position and the final position automatically comes.
The shortcoming of background technology is that the user can not take passages thereby finish text with selected mode selected interested character area on text image of custom.
Summary of the invention
The objective of the invention is to release a kind of literal extracts method based on camera and character recognition technology.The advantage of this method be the user can with the selected mode of custom the selected interested literal of text image, thereby finish the text extracts.
To achieve these goals, the present invention by the following technical solutions.Be placed with the program that control and commander CPU carry out following operation at the store memory of the smart machine of existing analysis with text image and character identification function: show that at the display of described smart machine the interface of text image confirms the zone of the interested literal that the user selectes with the selected mode of custom, analyze and the interior character image of literal identification selection area, order display Identification display result, preserve recognition result, finish the text extracts.
Now be described with reference to the accompanying drawings technical scheme of the present invention.
A kind of literal extracts method based on camera and character recognition technology, need in the smart machine of analysis with text image and character identification function, to implement, the user selects interested literal according to the literal that is presented on the display, it is characterized in that, described literal is a text image, also deposit the program that control and commander CPU carry out following operation in the described smart machine, described being operating as confirmed the zone of user with the selected interested literal of the selected mode of custom, the concrete operations step on the interface of the display videotex image of described smart machine:
The display videotex image of the described smart machine of the first step, the operating process of beginning execution contexts extracts, the user selects the mode in the zone of the selected interested literal be accustomed to;
Is second step selected: with the zone of line mode at the selected interested literal of text image? in this way, entered for the 4th step, as no, entered for the 3rd step;
The 3rd goes on foot to specify the zone of mode selected interested literal in text image of original position and final position;
The 4th step CPU analyzes and identifies the character image of user's appointment;
The 5th step cpu command display shows recognition result;
The 6th step customer inspection, correction, editor and preservation recognition result;
The 7th EOS: finish the text extracts.
Compare with background technology, the present invention has following advantage:
The present invention imitates people in the enterprising row labels of paper media such as books, newspapers and magazines, and the user's literal interested in the text image that the custom of selected interested literal comes camera is taken during view electronic documents is taken passages, both saved the time of the manual input of user, meet daily operating habit again, convenient and practical.
