Hi, I have a following problem that could use community wisdom.
I need to design a real word pattern/image that i can put on the floor or something has following features:
- can easily be detected by opencv, even if highly warped
- I should easily calculate camera matrix from it
- must hold small amount of data (like a number from 0-2^16)
- There will be many such markers in one image?
I was thinking QR codes but they are kinda hard to detect, maybe some combination of chessboard and QR inside?
