Tracking QR Code with Intel D435

August 01, 2019 13:21

We are trying to track QR codes on moving objects with the Intel D435, but having issues with the light reflecting on the surface of the printed QR codes. Has anybody from the community made experience with suitable materials?

The link below discusses a range of approaches for dealing with glare.

In addition to the anti-reflective film coating for cameras mentioned in the discussion, an alternative approach would be to apply such an anti-glare film to the surface of the QR markers to help stop light from reflecting back off them.

You may also find the discussion below interesting. It is about a user who was trying to track fiducial markers and was experiencing detection problems due to the IR dot pattern being projected onto the markers by the camera.
