location based augmented reality android application

Question

I am developing augmented reality android application based on real time location. It is a simple concept: my application should show some places around me. I have researched this intensively and yet I am still running into issues. I have my GPS coordinates and the target place's GPS coordinates.

My question is: How can I retrieve what my phone's camera is looking at (for example a building)? What is the logical way to solve something like this?

Answer 1

Augmented Reality will transfer real coordinates system to camera coordinates system. In AR Location-based, the real coordinate is Geographic coordinate system. We will convert the GPS coordinate (Latitude, Longitude, Altitude) to Navigation coordinate (East, North, Up), then transfer Navigation coordinate to Camera coordinate and display it on camera view.

I just create the demo for you: https://github.com/dat-ng/ar-location-based-android
