Overview
Model Zoo
The results are the 3D detection performance of moderate difficulty on the val set of KITTI dataset.
training time | Car@R40 | Pedestrian@R40 | Cyclist@R40 | download | |
---|---|---|---|---|---|
PGRCNN | ~4.5 hours | 85.25 | 58.37 | 75.04 | model-8.8M |
Note that the performance may vary a little due to sampling in PointNet++ encoder.
Installation
Please refer to INSTALL.md for the installation of OpenPCDet
.
To train PG-RCNN
, You need to additionally install pytorch3d
for utilizing Chamfer Distance.
We recommend using pytorch3d ver0.7.0.
Getting Started
Please refer to GETTING_STARTED.md to learn more usage about this project.
Important: Generate approximated complete object points
Under pcdet
directory, execute:
python -m pcdet.datasets.multifindbestfit
