Obstacle detection for visually impaired people


The Walkassist is a smart shoe developed by an austrian start-up called Tec-Innovation to enhance visually impaired peoples quality of life. The built-in warning system uses ultrasonic distance sensors to warn users of obstacles like steps, curbs or other people. If an obstacle is detected, the user is alerted using acoustic or vibration signals.

The objective of this project is to exploit additional visual information to support the ultrasonic based system. A camera based system placed on top of the toe-cap in combination with computer vision methods are used to detect obstacles and segment the walkable area, respectively.
