Hi, thank you for your good paper with beautiful code. I want to know how to train and test (data split) on the NuScenes dataset, and would you consider releasing the corresponding code?
In your readme.md, you mentioned SEQ_IDs such as 2350, 4950, 8120, 10200, 10750, 11400. How do I obtain these? I directly downloaded the Raw Velodyne Scans data, but it seems that I didn't see any information about SEQ_IDs.
The official website provides the following information:
So, are my SEQ_IDs 0000, 0002, 0003, 0004, and 0005?"
Thanks for your works. I'm testing on KITTI-360, I found the synthesized point stored as .npy. So I use this to convert it to pcd.
import numpy as np
import open3d as op
path = "./log/kitti360_lidar4d_f4950_release/results/test_lidar4d_ep0639_0002_depth_lidar.npy"
points = np.load(path)
print(points.shape,points[:10])
pcd = op.geometry.PointCloud()
pcd.points = op.utility.Vector3dVector(points)
op.io.write_point_cloud("2.pcd",pcd)
But it looks like the depths are wrong. Below image is captured from pcl_viewer
Below image is corresponding depth map
This is the output of evaluation
Could you please help me find where is wrong?

Hi,
This is excellent work. I am very grateful for your sharing.
However, I see that the experiments were conducted by training and testing on each sequence individually. How were the final metrics obtained? In other words, were all the experiments in this paper conducted using scene 4950 from the sequence 2013_05_28_drive_0000 for both training and testing? Or were there other setups?
Hi,
I'm very interested in your work.
I noticed that the code only uses the sequence 2013_05_28_drive_0000
, and the frame splitting is hard-coded.
My questions are:
2013_05_28_drive_0000
or all sequences?data/preprocess/generate_rangeview.py, line 73
same file, line 112
