LiDAR-Transfer

Transfer SemanticKITTI labeles into other dataset/sensor formats.

Content

• Convert datasets (NUSCENES, FORD, NCLT) to KITTI format
• Minimal dataset minimal.zip
• Visualize with visualizer.py
• Transfer datasets lidar_deform.py

Usage

Install Dependencies

pip install pyaml pyqt5 scikit-image scipy torchvision

pip install pycuda

pip install vispy

Or use local installation to apply antialias patch

git clone https://github.com/vispy/vispy.git
cd vispy
git apply ../lidar_transfer/vispy_antialias.patch
pip install -e .

Finally, you have to compile the ray tracer in auxiliary/raytracer, i.e.,

$ cd auxiliary/raytracer/ 
$ make

Get started

1. Unzip minimal.zip
2. Run

   python lidar_deform.py -d minimal
   

3. Run with target sensor

   python lidar_deform.py -d minimal -t minimal/target.yaml
   

4. Change parameter in config/lidar_transfer.yaml
