前言
Amusi 发现了一个超快速3D目标检测网络!SFA3D:基于LiDAR的实时、准确的3D目标检测模型,在GTX 1080 Ti上速度高达95 FPS!代码现已开源!
主要特性:
1. 快速训练和推理;
2. Anchor-free的方法;
3. 无NMS;
4. 支持分布式数据并行训练 演示Demo详见视频

点击下面该视频,皆可查看演示Demo
The technical details are described here
Update 2020.09.06: Add ROS
source code. The great work has been done by @AhmedARadwan. The implementation is here
The instructions for setting up a virtual environment is here.
git clone https://github.com/maudzung/SFA3D.git SFA3D
cd SFA3D/
pip install .
Download the 3D KITTI detection dataset from here.
The downloaded data includes:
Please make sure that you construct the source code & dataset directories structure as below.
To visualize 3D point clouds with 3D boxes, let's execute:
cd sfa/data_process/
python kitti_dataset.py
The pre-trained model was pushed to this repo.
python test.py --gpu_idx 0 --peak_thresh 0.2
python demo_2_sides.py --gpu_idx 0 --peak_thresh 0.2
The data for the demonstration will be automatically downloaded by executing the above command.
python train.py --gpu_idx 0
python train.py --multiprocessing-distributed --world-size 1 --rank 0 --batch_size 64 --num_workers 8
Two machines (two nodes), multiple GPUs
python train.py --dist-url 'tcp://IP_OF_NODE1:FREEPORT' --multiprocessing-distributed --world-size 2 --rank 0 --batch_size 64 --num_workers 8
python train.py --dist-url 'tcp://IP_OF_NODE2:FREEPORT' --multiprocessing-distributed --world-size 2 --rank 1 --batch_size 64 --num_workers 8
