WSVI

WASVI : Walking Assistance System for the Visually Impaired in Real-Time

Methods

[1]. Object Detection : to detect the specific object(person, car, etc.) in each frames. [2]. Multi Object Tracking : to assign and maintain a unique ID to each object in a video. [3]. Traffic Light Detection : to detect the traffic light signal which is various over the country. [4]. Pedestrian Intention Prediction : to make the system possible to predict the surrounding pedestrian intention.

Asuumption

The visually impaired has ability to follow the direction well with his cane on the sidewalk. They don't visit the crowded place. They go to fiamilar, and frequently visited place.

Our Contribution

Make the system possible to predict the surrounding pedestrian movement. Detect the traffic light and consider the signal which is dependent on the country Detect the crosswalk and its direction(not yet)
