A stereo vision-based aid for the visually impaired

Abstract:

This paper describes a portable vision-based obstacle detection system, intended for use by blind people. The system combines an obstacle detection system designed tor AGVs with recalibration of ground position and a Kalman Filter based model of the person's walking movement. The system uses stereo vision. Obstacle detection is achieved through comparison of the disparity seen with that expected from the position of the ground. Recalibration of ground position is made by plane fitting in the ...
