Hey guys,
im working on a homework about AR and there is so much information in books etc.. some books i got are from 2010 so this is not state of the art i guess. I red a lot about tracking and i just wanted to ask you if i got it correctly.
So my iPhone for example uses Optical Tracking(?) it can be use this in two different ways:
marker-based: the camera spots an highlighted spot and insert an virtual graphic exactly on this spot (sorry for the wording, i dont know better words for this in english)
and
marker-less: my device uses SLAM in combination with LiDAR to generate a map from my environment and then a smartphone app can put virtual objects next to me for example ? Like the Reality Composer App from Apple
is this nearly correct or am i wrong? So i need just a basic explanation of Marker-Based and Marker-Less Tracking only for AR.
Thank you guys
