Abstract

Blind people face several problems in their life, one of these problems
that is the most important one is detection the obstacles when they
are walking. In this project, we suggested a system with one motion
detection sensor placed on blind person's helmet that their duty is
taking obstacles from front sides. In this method, first we investigate
the probability of existence an object by use of special points that
then we will call them "Equivalent points", then we utilize binary
method, standardize and normalized cross-correlation for verifying
this probability. This whole system powered by solar power . If any
obstacle found by sensor then it indicates that person by buzzer and
vibration.
