Did you perform experiments on Lidar Segmentation task?

Hello, really impressive work! Your dense occupancy label generation pipeline is very enlightening. I notice that SurroundOcc achieves SOTA results on 3d Semantic Occupancy prediction and 3D scene completion tasks. But did you perform experiments on Lidar segmentation task? I wonder whether on this task, SurroundOcc also outperforms TPVFormer. If I have to do Lidar segmentation with SurroundOcc by myself, besides the dataset change, what else changes should I make to the model to make it work on this task instead of occupancy prediction?

Hi, thanks for your appreciation of our work. We do not conduct LiDAR segmentation experiments since we it cannot verify 3D reconstruction performance. If you want to do LiDAR segmentation, you can refer to TPVFormer and especially note the segmentation label assignment.
