Embodiment Construction

[0030] specific implementation plan

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0032] figure 1 It is a block diagram of the present invention, and the specific implementation includes the following steps:

[0033] When the micro camera is enabled, the camera focus function will automatically start to execute, and the focus will be selected in the target text area to focus and shoot to obtain an image.

[0034] The captured image is sent to a digital image processor, where the image is grayscaled, binarized, segmented, extracted, and the image is converted into a digital quantity that the processor can recognize:

[0035] A. Grayscale: convert the collected RGB image into a grayscale image;

[0036] B. Noise reduction: use the gray scale linear addition method to improve the signal-to-noise ratio;

[0037] C. Binarization: Analyze the grayscale image to be processed, select a suit...

Abstract

The invention relates to auxiliary reading glasses for visual impairment people. The glasses comprise a miniature camera installed on the glasses, a processor, a text and voice conversion module, an upper headset installed on a glasses frame and a power source. A text file image shot by the miniature camera is processed to be a text file through the processor, then the text file is converted into an audio file through the text and voice conversion module, and the audio file is output through the headset. Due to the fact that after the image is converted into character information, and characters are converted into voice information, voice signals of the character information are output through the headset, visual impairment people can directly read the text file through the auxiliary reading glasses, and great convenience is brought to visual impairment people for reading.

Description

technical field [0001] The invention belongs to the technical field of portable intelligent terminals, in particular to auxiliary reading glasses for people with visual impairments that can achieve character recognition and reading aloud functions. Background technique [0002] With the rapid development of science and technology, more and more wearable smart devices have appeared in people's sight, such as smart phones, smart watches, smart glasses, etc. However, the increasingly serious vision problems plague the visually impaired people. Reading has become a problem that cannot be ignored for the visually impaired people. How to use existing technologies to help the visually impaired people to read is gradually attracting attention. [0003] In the existing smart glasses, more entertainment is considered. For example, Google Glass can control photos, video calls and identify directions through voice, as well as surf the Internet, process text messages and emails. Upload...
