If I run the ‘positional_tracking.py’ file and move the camera close to the wall, the pose information has a large drift and the state stuck on “SEARCHING” and I can not get the correct pose of the camera. How can I fix this problem to get the pose of the camera even it is close to a plane or an object?

Hi @chris-s907,

The easiest solution would be to use the last value before going into SEARCHING, as under 0.3m (especially looking at a uniform surface) most of our cameras, the not “Mini” models, will fail to give an accurate depth, used for the positional tracking. They will then go into searching state.
