NAV-AR

What is NAV-AR ?

NAV-AR is a mobile application that delivers highly accurate indoor mapping and navigation using Augmented Reality built on the principles of SLAM.

Inspiration

In this age almost every inch of our world is already mapped. You’ll navigate using google maps or some other GPS app. However, once you reach your destination and go indoors, GPS has no line of sight and you go back for asking directions. This is where NAV-AR “comes into play”.

How We built it

We built Nav-AR by use of SLAM i.e., Simultaneous Localization and Mapping, a computational technique that involves the task of constructing an internal map of an unknown area whilst keeping track of its position inside the area. Next we rendered the map and made use of A* pathfinding algorithm for finding shortest path. To deliver a highly interactive Augmented Reality Experience, we used Unity Engine and Google ARCore. Lastly we made use of a QR code scan mechanism for calibration and localisation purposes.

Our Team built NAV-AR using :

• Unity
• Google ARCore
• SLAM
• C#
• A* Pathfinding algo

Challenges We ran into

(re)positioning the user inside the map while navigation

Accomplishments that we are proud of

Creating a fully functional Augmented Reality app(prototype) in a short span of time with a explanation video of the same

What we learned

Implementing Augmented Reality, A* Pathfinding algo for, baking navmesh and had a great experience.

What's next for

Making it more cloud dependent so that the user can download the map from the database to navigate.
