基于多传感器融合的智能导盲杖研制
|
摘要
针对盲人现实生活中外出行走的不便性,在现有导盲杖技术基础上,例如超声测距、电子罗盘和GPS定位以外,提出了一种新型多功能导盲杖,针对盲人反映较多的问题,该导盲杖具有可检测路面积水、检测下行台阶等功能。讨论了目前导盲杖现有技术的局限性,给出了改进设计方案、检测原理和测量结果。最后经测量,该导盲杖各功能、技术指标等参数符合设计要求,有望对盲人的出行带来极大的便利。
Based on the inconvenience of the blind in the real life,a new type of multi-functional guide rod is proposed,which is on the basis of the existing guide rod technology,such as ultrasonic ranging,electronic compass and GPS.This guide rod can test gathered water areas,down steps and others.Mainly focused on the analysis of the guide rod' s technical limitations,the improvement design,detection principle and measurement result are given.With the final detection,the guide rod' s parameters,such as the functions and technical indictor,meet the design requirements,and it would be expected to bring great convenience to the travel for the blind.
