I’m capturing point clouds with Astra Mini and I noticed that Z value resolution is pretty coarse at longer distances. For example, at ~2.6m distance to a flat target, the resolution is about 28mm, i.e. I’m getting these points:
[-123.9576 -187.60762 2682. ]
[-118.79163 -187.60762 2682. ]
[-113.625656 -187.60762 2682. ]
[-108.45967 -187.60762 2682. ]
[ 51.146034 -185.649 2654. ]
[ 56.25808 -185.649 2654. ]
[ 61.37012 -185.649 2654. ]
[ 66.48217 -185.649 2654. ]
and no points with Z coordintes between 2654 and 2682. Is this normal?
Where can I find the Z resolution specifications for Orbbec 3D cameras? I need finer resolution than 28mm at 2.6m distance to target.
