Problems solved by technology

For example, it is more convenient to use a red line to press the target character, but it cannot prevent the problem of tilting the characters, which will reduce the recognition rate; and for the method of recognizing the entire business card, it will not only increase the workload, but also increase the recognition rate. It is even more impossible to prevent the tilt of the captured image from appearing
At the same time, because there is a lot of useless information for the operator, it interferes with the process of obtaining information of interest to the operator; in the case of positioning with a rectangular frame, the size of the rectangular frame is not easy to determine and brings inconvenience to the shooting. Necessary content, too small to fully contain the target characters to be recognized

Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] One of the implementation methods:

[0017] In the first step, the operator activates the camera function of the mobile terminal equipped with the camera device to take images. At this time, it is required that the position of the character to be recognized in the captured image does not have a large horizontal or vertical tilt or flip.

[0018] In the second step, the user of the mobile terminal with the camera starts the auxiliary positioning function, and a cross positioning cursor is displayed on the display screen of the mobile terminal with the camera. The shape of the positioning cursor is a cross shape, the abscissa and ordinate can be a solid line or a dashed line, and the origin is a solid or hollow dot.

[0019] In the third step, the user of the mobile terminal with the camera moves and locates the origin of the c...

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...
