Method and terminal for rectifying deviation of file

Abstract

The invention relates to a method and a terminal for rectifying deviation of a file. The terminal comprises an image acquisition and processing module, an image inclination angle detection module and an image deviation rectifying and correcting module, wherein the image acquisition and processing module takes a picture of a file through a camera, acquires an image and processes the file image to obtain a black and white two-dimensional image; the image inclination angle detection module detects the inclination angle of the file image by an image inclination angle detection algorithm; and the image deviation rectifying and correcting module performs deviation rectifying on the image of a visiting card to obtain a corrected image of the visiting card according to the inclination angle of the image of the visiting card detected by the image inclination angle detection module. According to the technical scheme, the deviation of the file image is finally rectified through OCR word identification, text category identification and information checking, amending and authentication, so the method and the terminal overcome the defect of low scan information identification rate existing in the prior art and improve the identification accuracy of the information.

Description

technical field [0001] The present invention relates to the technical field of portable communication terminals, and more specifically, to a method and a terminal for realizing deviation correction of files. Background technique [0002] With the continuous development of mobile communication technology and mobile communication terminals, mobile phones with camera functions are becoming more and more popular. Almost all smart phones are equipped with camera functions, and the pixels are constantly improving; in addition, mobile phones with touch screens have realized The revolutionary change in the input mode marks the qualitative leap of mobile phones from keyboards to keyboardless, all of which also create conditions for the scanning of business cards, documents and other materials. Judging from the current situation of the mobile phone market, scanning of business cards and documents has become an important function of many business mobile phones. In addition, Chinese pa...

Problems solved by technology

However, the existing business card scanning technology has the following defects: in the step (1) of realizing the business card scanning function, the mobile phone user needs to use the camera of the mobile phone to take a picture of the business card. Factors such as jitter and other factors generated during the shooting process of mobile phone users will inevitably cause a certain degree of skew in the finally obtained business card or document image, resulting in a decline in the recognition rate of business card or document information when scanning

Experiments have proved that: an angle of more than 3° will cause obvious deformation of characters, and most OCR technologies are difficult to adapt to, resulting in a decrease in the accuracy of OCR technology for recognizing characters in business card images, and also affecting mobile phone users. The use of business card or document scanning functions to experience
