I am trying to perform the tests using the Port 3 Chart (on SR 300 camera). However, the fiducial markers are never properly detected in the color stream, and the black circles are not properly detected in the depth stream (part of them are hardly shown). The fiducial markers are properly detected only while locating the chart further away from the camera (about 150cm), but this distance is obviously out of the depth camera range.
I printed the chart and joined it's parts myself (scaled so that the protruding square is 12cm*12cm), and attached a home-made carton protruding square. The lighting conditions seem to be satisfactory.
Do you have a clue for what should I do to make it work?
