Pointnet2.PyTorch

• PyTorch implementation of PointNet++ based on erikwijmans/Pointnet2_PyTorch.
• Faster than the original codes by re-implementing the CUDA operations.

Installation

Requirements

• Linux (tested on Ubuntu 14.04/16.04)
• Python 3.6+
• PyTorch 1.0

Install

Install this library by running the following command:

cd pointnet2
python setup.py install
cd ../

Examples

Here I provide a simple example to use this library in the task of KITTI ourdoor foreground point cloud segmentation, and you could refer to the paper PointRCNN for the details of task description and foreground label generation.

1. Download the training data from KITTI 3D object detection website and organize the downloaded files as follows:

   Pointnet2.PyTorch

   │   │  train_and_eval.py

2. Run the following command to train and evaluate:

   cd tools
   python train_and_eval.py --batch_size 8 --epochs 100 --ckpt_save_interval 2
