Our project was to design a navigation system for the visually impaired. Since this has been a problem that has gone through research over the years we had to learn and apply some of the previous works done by researchers to solve this problem

We used a 3 D camera so that we could accurately capture the depth and distance information. A detailed analysis on the steps followed to calibrate this camera and also an entire analysis on the methodology and future works are available in the report attached below
