I am a PhD candidate of University of Melbourne and currently researching on the Application of AR for underground Utilities.
There have few works been done already in this area, but this needs significant development. Such as Virtual model anchoring and parallax caused on under ground pipes (Depth perception)..etc.
If there is anyone who are working in the similar projects, I would appreciate your thoughts on the above mentioned issues. instead you can reach me via firstname.lastname@example.org
