面向视障人群的视听辅助装置设计

Design of Audio-visual Aid for Visually Impaired People

近年来,我国老年人人口数量占全国人口数量的比例持续上升,视障人群的占比也随之持续增加。针对这一问题,文章设计一款面向视障人群的视听辅助装置。该装置以Mega2560为核心控制器,与视觉模块、超声波模块、语音合成模块等共同实现目标检测、测距、语音播报、屏幕显示等功能。选用卷积神经网络进行目标检测与识别,提高了目标识别的精度。所设计的装置提高了视障人群的便利性与安全感,具有很高的应用价值。

In recent years,the proportion of the elderly population in the national population has continued to rise,and the proportion of the visually impaired population has also continued to increase.To solve this problem,this paper designs an audio-visual aid for visually impaired people.The device takes Mega2560 as the core controller and realizes the functions of target detection,ranging,voice broadcasting,screen display and so on together with vision module,ultrasonic module and voice synthesis module.The convolutional neural network is selected for target detection and recognition,which improves the accuracy of target recognition.The designed device improves the convenience and sense of security of visually impaired people,and has high application value.
