Embodiment 1

[0041] 1) First, the image is collected from left to right, and the two points left by the previous group of dot matrix on the left can be excluded (that is, the point with no center point mark on the center of gravity in Figure b).

[0042] 2) Carry out binarization processing to the image again, and change the image into an image with only two gray levels of 0 or 255 (such as Figure 8 ).

[0043] 3) There are some small black dots in the image. These interference dots are caused by burrs on paper books, but these dots do not meet the area requirements. Therefore, using the open operation to exclude them will not affect the recognition of Braille bumps .

[0044] 4) Carry out connected domain detection again, and observe at the same time Figure 8It is found that there are large white irregular areas in the central area, which are caused by inconsistent pressing pressure; but in the roundness calculation formula, the roundness values ​​of these areas are all less than the ...

Abstract

The invention relates to a braille reading pen, and aims to provide a rolling type braille reading pen for identifying a paper braille book to solve the problem that the blind are difficult to read books. The rolling type braille reading pen for identifying the paper braille book is characterized in that the pen comprises a reading pen body and a roller which is rotatably positioned at one end ofthe pen body; a roller pressure pre-processing module, a central control module, a voice module, a button switch and a lithium battery are installed in the reading pen body, wherein the various modules are connected through data wires; a plurality of pressure sensors forming a micro pressure dot matrix area are evenly distributed on the surface of the roller so as to achieve transverse continuousacquiring of the pressure information of the braille dot matrix salient dots, and the braille identification roller is connected with the pressure pre-processing module in the pen body through a datawire so as to achieve data transmission.

Description

technical field [0001] The invention relates to a new type of braille reading pen, specifically a rolling type braille reading pen used for paper braille document identification. technical background [0002] At present, there is a single way to learn Braille, and the current Braille has no tones, and there are identical and similar lattices, making learning extremely difficult. The development of flexible sensors for paper-based Braille book recognition can enable blind people to read Braille information when they cannot learn Braille, solve daily needs, and learn Braille quickly and effectively without the guidance of others. This device can solve the current situation of blind people's difficulty in reading, improve the current situation of low education level of blind people, allow more blind people to have access to Braille, learn Braille, make learning Braille more efficient and simple, and then improve the level of employability of blind people , to improve the livin...
