Re: tracking marker

Hi,

the fiducial markers are detected using the Aruco library
the featured markers are detected using the Orb algorithm provided in OpenCV (for the current version available on the scol trunk)

Hi azis ! smile

If you want to know more about ORB algorithm, you can take this : https://willowgarage.com/sites/default/ … _final.pdf
The document is on the developer's website which programs OpenCV. wink
