I am working on new project for my QuadCopter : Precision Landing , and I am trying to mix 2 tracking scripts + Color Tracking and April Tag tracking.
Color Tracking works OK if you can really tune the filter for the correct lighting and surrounding, best is still a red patch on a grass field
April Tag is quite precise for short range but with low resolution (QQVGA) its missing range.
Here is a demo with OpenMV: https://youtu.be/IJlt8dE_s5k
So my idea is to build a compound landing pad : 1 Meter Square Red Sheet with a 30cmx30cm April Tag in the center.
The quadcopter would initiate precision landing based on the color and then it would switch to April Tag.
Considering that we might not enough memory to get both process simultaneously, is there a method to switch from Color to Tag when the blob is bigger than “N” pixels ?
