Hi, I try auto label with Nuscenes mini dataset. I visualize the point cloud but the sweep point cloud translation is wrong. But I got the correct ROI values. what is the reason and is it correct?

the command is "bash cfgs/target_nuscenes/label_generation/round1/scripts/generate_ensemble_preds.sh"

This is more of a visualisation issue. From your visualised point cloud, it looks like your x,y values are fine but your z values are mostly 0 in the 'points' array. Maybe check if any transform was done to compress the point cloud into a BEV in the data loader.

We have provided visualisation code for you, we recommend trying those out.
