An Intelligent Assistive Navigation Guide System for Blind and Visually Impaired Individuals Using Deep Learning Techniques

Authors: Osita Miracle Nwakeze | DOI: 10.63665/ijetd-y2f2a001

To satisfy the need for more advanced and reliable navigation support systems, a growing number of visually impaired people is faced with the problem of navigation in various environments, and conventional assistive devices, like white canes or common electronic aids, are not sufficient. This work was aimed at creating a smart real-time assistive system to detect the surrounding obstacles, estimate its distance from the user, and give immediate audio information to help to move safely and independently.
