specific Embodiment 1

[0070] from figure 2 In the text shown, the Chinese character "帝" is chosen to be recognized and input into the mobile terminal device.

[0071] The selection rule in this embodiment stipulates that: the first image unit on the right of the position where the origin is recognized is the first word, individual character or symbol to be recognized. Its working steps are as follows:

[0072] 1. The beam emitting module activates the beam emitting device, and irradiates the beam to the left side of the word "Emperor" on the text to form a spot;

[0073] 2. The image acquisition module starts the camera device, captures the text and obtains the image;

[0074] 3. The image processing module performs tilt correction, denoising, inversion, grayscale and other processing on the image, and then divides it into image units to form an arrangement of image units;

[0075] 4. The positioning module finds the position of the spot and defines the origin of identification;

[0076] 5. Th...

specific Embodiment 2

[0079] from figure 2 In the text shown, the word "dream" is chosen to be recognized and input into the mobile terminal device.

[0080] The selection rule in this embodiment stipulates that: the image unit where the recognition origin is located is the first word, single character or symbol to be recognized. Its working steps are as follows:

[0081] 1. The beam emitting module activates the beam emitting device, and irradiates the beam onto the word "dream" on the text to form a spot;

[0082] 2. The image acquisition module starts the camera device, captures the text and obtains the image;

[0083] 3. The image processing module performs tilt correction, denoising, inversion, grayscale and other processing on the image, and then divides it into image units to form an arrangement of image units;

[0084] 4. The positioning module finds the position of the spot and defines the origin of identification;

[0085] 5. The selection module takes the recognition origin as the s...

specific Embodiment 3

[0088] from figure 2 In the text shown, the Chinese "White Emperor City" is selected, recognized and input into the mobile terminal device.

[0089] The selection rule in this embodiment stipulates that: the origin of recognition is located at the first word of the phrase or the image unit corresponding to a single character. Select right to the third image cell. Its working steps are as follows:

[0090] 1. The beam emitting module activates the beam emitting device, and irradiates the beam onto the character "白" in the phrase "白帝城" to form a light spot;

[0091] 2. The image acquisition module starts the camera device, captures the text and obtains the image;

[0092] 3. The image processing module performs tilt correction, denoising, inversion, grayscale and other processing on the image, and then divides it into image units to form an arrangement of image units;

[0093] 4. The positioning module finds the position of the spot and defines the origin of identification;...

Abstract

The invention provides a character recognition input system using optical localization and a method thereof. The system is provided with two optical operation devices on a hardware structure, namely a light beam emitting device and a photographic device like a camera. The construction and work method of the system are as follows: 1, the light beam emitting module starts a light beam emitting device to form a light spot on the surface of a text; 2, an image acquiring module starts the photographic device to obtain a text image; 3; an image processing module divides the text image by using a word, an individual character and a symbol as an elementary unit to form an image unit arrangement; 4, a recognition original point locating module defines the position of a light spot in the text image as a recognition original point; 5, an image unit selecting module selects single or a plurality of image units in the image unit arrangement by using the recognition original point as a start point; 6, an OCR (optical character recognition) module recognizes the selected image unit as the character and symbol; and 7, an input module inputs the character and symbol in relative software in a mobile terminal apparatus. The character recognition input system using optical localization and the method thereof are suitable for various mobile terminal apparatuses.

Description

Technical field [0001] The invention relates to the field of image acquisition and processing of mobile terminal equipment and optical character recognition, in particular to a character recognition input system and method using optical positioning. Background technique [0002] At present, there are two main methods of inputting characters in printed text or handwritten text into computers or mobile terminal devices through optical character recognition (OCR) technology: one is to use scanning technology to obtain images of texts and then perform character recognition; It is to obtain the image of the text through the camera device and then perform character recognition. [0003] Although scanning technology can obtain text images stably and clearly, it often requires an external fixed scanning device. This is not suitable for the use requirements of mobile terminal equipment. In some products, such as a scanning translation pen, a structure with a scanning function is de...
