I want to detect marker within marker, like your Bert and Ernie Video sample First you guys detect first marker and draw walls around that and when you put Bert on First marker it becomes also second marker and show virtual object of Bert. I want to do same replica but I am using Just image any super hero and a ground as a marker. I want to do same task which you are doing but only difference I am using simple images as a marker. So I am getting confuse on two things.
How Can I detect marker within marker.
How can I able to detect second marker when it comes in range of First marker, just like you guys are doing in Bert and Ernie sample.
Help me on that, this will be great for me. Thanks in advance.
