基于视觉检测技术的可佩戴式盲人智能导航仪研制

Development of Wearable Intelligent Navigation Instrument for Blind People Based on Visual Detection Technology

针对市场上辅盲设备成本高、功能不全面、误差大以及智能化程度低的问题,设计了一种基于视觉检测技术的可佩戴式盲人智能导航仪。该装置分为下位机控制终端和上位机用户作端两部分,下位机实时采集语音、图像等信号,上位机接收并进行处理。装置中运用了OV7670避障模块、BDS导航模块以及语音交互模块,可以实时采集路况与盲人用户的语音信息,并结合相应的手机App进行远程管理,保障盲人用户安全便利出行。

Aiming at the problems of high cost,incomplete function,large error and low intelligence degree of auxiliary blind equipment in the market,a wearable intelligent navigation instrument for blind people based on visual detection technology was designed.The device is divided into two parts:The lower computer control terminal and the upper computer user terminal.The lower computer collects voice,image and other signals in real time,and the upper computer receives and processes them.OV7670 obstacle avoidance module,BDS navigation module and voice interaction module are used in the device,which can collect real-time road conditions and voice information of blind users,and carry out remote management combined with corresponding mobile Apps to ensure the safety and convenience of blind users.
