Wrong normalization on Kitti?

proj = torch.cat([proj_range.unsqueeze(0).clone(),
proj_xyz.clone().permute(2,0,1),
proj_remission.unsqueeze(0).clone()])
proj = (proj - self.sensor_img_means[:, None, None]) / self.sensor_img_stds[:, None, None]
The order of channels in proj
is (range, z, x, y, remission), but sensor_image_means
is in the order of (range,x,y,z,signal) or something else (based if it's V321 or V353)?
So I guess here's something wrong?

Sorry for my late reply, I did't notice the issue recently. Yes, I made a small mistake here, while we also find the normalization on the KITTI doesn't have much influence and just slight drops the performance. It is true that right normalization with accurate mean and std are better. We will update this soon.
