Dataset

SynLiDAR is a large-scale synthetic LiDAR sequential point cloud dataset with point-wise annotations. 13 sequences of LiDAR point cloud with around 20k scans (over 19 billion points and 32 semantic classes) are collected from virtual urban cities, suburban towns, neighborhood, and harbor.

Download (245.3GB)

  1. You can download SynLiDAR through browser → DR-NTU

  2. You can also download through provided python script, this requires installing pyDataverse

pip install pyDataverse
python download.py

Note: For most of sequences, we compressed and split them into multiple small files. Please download them and cat into one file before extraction. E.g. for sequence 01:

cat 01*>01.tar.gz
tar -zxvf 11.tar.gz

The data should organized in the following format:

/SynLiDAR/
  └── 00/
    └── velodyne
      └── 000000.bin
      ├── 000001.bin
      ...
    └── labels
      └── 000000.label
      ├── 000001.label
      ...
  ...
  └── annotations.yaml
  └── read_data.py

We provide class annotations (in 'annotations.yaml') and example python code for reading data (in 'read_data.py').
