I have a problem when I detect a small pixel (length and width both both are smaller than 0.4 cm) of aruco marker. Is there anyway to solve this problem by Android Java?

It is not android or java problem. It is just how ArUco library works. While searching of markers it declines whose who are too small. Try to adjust MarkerDetector::Params::_minSize parameter.

Also, can you provide sample image? Once I had problem with very small marker which was caused by bad printer resolution - marker had visual defects, which affected their detection.

  • Marker looks normal and its size is ok. Have you tried to capture same marker of bigger size? Does it capture properly? Have you tried to vary `MarkerDetector::Params::_minSize` as I suggested? – Melnikov Sergei Aug 04 '17 at 11:53
