【摘要】：為了保障盲人行路安全,設(shè)計基于智能視覺導(dǎo)航的盲人指路設(shè)備。介紹了設(shè)備設(shè)計方案,為智能視覺模塊選擇CMOS單片機和OV單片機,周期性地采集盲人行路圖像,通過對比圖像灰度值確定路面是否存在障礙物。采用PFGA控制智能視覺模塊時序,計算障礙物位置,進而提供導(dǎo)航線路,通過串口通信電路將導(dǎo)航線路傳給語音模塊進行播報。通過對比實驗證明,基于智能視覺導(dǎo)航的盲人指路設(shè)備具備較強的實時性和魯棒性。
[Abstract]:In order to ensure the safety of blind people, a blind guide device based on intelligent visual navigation is designed. The design scheme of the equipment is introduced. The CMOS and OV microcontroller are selected for the intelligent visual module. The blind road images are collected periodically, and the road obstacles are determined by comparing the gray values of the images. The PFGA is used to control the timing of the intelligent visual module, to calculate the position of the obstacle, and then to provide the navigation circuit. The navigation circuit is transmitted to the voice module through the serial communication circuit. The comparison experiment shows that the blind guide device based on intelligent visual navigation has strong real-time and robustness.
