Embodiment

[0030] refer to Figure 1-2 , an English secondary Braille conversion system based on image acquisition and correction, including:

[0031] An image acquisition and processing device, the image acquisition and processing device includes a scanning unit and an identification module, the identification module is electrically connected to a CCD / CMOS sensing module and an image conversion module, the CCD / CMOS sensing module is electrically connected to the scanning unit, and the image conversion module is electrically connected The image upload module is connected to the image upload module, and the image upload module is electrically connected to the cloud database. When the system is running, the scanning unit is first required to collect the original video. The scanning unit here includes a surveillance camera, a camera, and a video capture device. When scanning After the unit collects the first-hand video data and image data, it is transmitted to the recognition module for ima...

Abstract

The invention discloses an English secondary braille alphabet conversion system based on image acquisition and correction. The system comprises an image acquisition and processing device, the image acquisition and processing device comprises a scanning unit and an identification module. The identification module is electrically connected with a CCD/CMOS sensing module and an image conversion module. The CCD/CMOS sensing module is electrically connected with the scanning unit; the image conversion module is electrically connected with an image uploading module; the image uploading module is electrically connected with a cloud database, when the system operates, the scanning unit is required to perform original video acquisition firstly, the scanning unit comprises a monitoring camera, and after the scanning unit acquires video data and image data of a first hand, the scanning unit is used for acquiring the video data and image data of the first hand. The system has the advantages that the recognition unit is electrically connected with the noise reduction module; and the image synthesis filtering unit synthesizes the processed high-frequency sub-band coefficient and low-frequency sub-band coefficient to obtain an image without noisy points, thereby ensuring that subsequent text recognition is accurate and errorless.

Description

technical field [0001] The invention relates to the technical field of Braille conversion, in particular to an English secondary Braille conversion system based on image acquisition and correction. Background technique [0002] Braille, also known as Braille and raised characters, its smallest unit is "square", which is composed of six dots arranged in a certain irregular pattern. It is specially designed for the visually impaired and relies on tactile perception. It is also a visually impaired The primary means of written communication for people. [0003] The current international Braille "Braille" was created in 1824 by French blind Louis Blaille. Referring to the Blair Braille system in 1952, on the basis of the old Braille characters such as "Xinmu Keming Braille", after adjustment and innovation, China proposed "Mandarin" based on Putonghua, with Beijing phonetics as the standard, using the method of participle ligatures to spell Putonghua "New Braille Program" (comm...
