Abstract

The invention discloses an auxiliary positioning technology for the recognized character used in mobile end yielding OCR function with camera, which comprises the following steps: 1) the operator uses mobile end to shoot the object with character picture information, then it opens the auxiliary positioning function so that the screen displays the tracking cross. The operator moves the cross to let the zero point position inside or on the left angle of the recognized character; at last, it presses the ascertaining key and auto recognizing. 2) The operator opens the mobile end OCR shoot function; the mobile end screen displays a tracking cross. Then the operator adjusts the opposite position to let the zero point position inside or on the left angle of the recognized character; at last, it shoots the picture and auto recognizes it.

Description

Technical field

[0001] The invention provides a novel auxiliary positioning technology for realizing the OCR function on a mobile terminal with a camera device. It uses a cross-cursor assisted positioning method with an origin to realize the terminal operator's accurate positioning of the character to be recognized, and combines OCR to achieve the purpose of the operator quickly obtaining information. technical background

[0002] Existing smart terminals and PDAs with OCR function have certain inconveniences and defects in the implementation of positioning technology before optical character recognition. They cannot easily locate the characters to be recognized, which brings the recognition process Disadvantages such as large amount of calculation and long time consumption.

[0003] Existing OCR function mobile phones have adopted methods to press a red line on the target character when carrying out business card recognition and positioning, and also have the method of dir...
