QR code’s are a form of fiducial markers. However, detection is far different than orientation. Also for things like AR, you need quicker detection and orientation, which QR code’s don’t afford
- Robotbeat 6y agoYup. And Actually, you need to know the corners of the QR code pretty precisely to actually de-skew the QR tag to pull out the code from it, and it’s an easy transformation to get 6dof orientation and translation from that (although you need some idea about the camera optics, but that’s easy to calibrate with similar techniques beforehand). You’re right about about speed, though, and some fiducials are much more resistant to motion blur than QR codes are (and work with much lower resolution cameras).
