Ultra-Fast-Lane-Detection

PyTorch implementation of the paper "Ultra Fast Structure-aware Deep Lane Detection".

[July 18, 2022] Updates: The new version of our method has been accepted by TPAMI 2022. Code is available here.

[June 28, 2021] Updates: we will release an extended version, which improves 6.3 points of F1 on CULane with the ResNet-18 backbone compared with the ECCV version.

Updates: Our paper has been accepted by ECCV2020.

The evaluation code is modified from SCNN and Tusimple Benchmark.

Caffe model and prototxt can be found here.

Demo

Install

Please see INSTALL.md

Get started

First of all, please modify data_root and log_path in your configs/culane.py or configs/tusimple.py config according to your environment.

• data_root is the path of your CULane dataset or Tusimple dataset.
• log_path is where tensorboard logs, trained models and code backup are stored. It should be placed outside of this project.

---

For single gpu training, run

python train.py configs/path_to_your_config

For multi-gpu training, run

sh launch_training.sh

or

python -m torch.distributed.launch --nproc_per_node=$NGPUS train.py configs/path_to_your_config

If there is no pretrained torchvision model, multi-gpu training may result in multiple downloading. You can first download the corresponding models manually, and then restart the multi-gpu training.

Since our code has auto backup function which will copy all codes to the log_path according to the gitignore, additional temp file might also be copied if it is not filtered by gitignore, which may block the execution if the temp files are large. So you should keep the working directory clean.

---

Besides config style settings, we also support command line style one. You can override a setting like

python train.py configs/path_to_your_config --batch_size 8

The batch_size will be set to 8 during training.

---

To visualize the log with tensorboard, run

tensorboard --logdir log_path --bind_all

Trained models

We provide two trained Res-18 models on CULane and Tusimple.

Dataset	Metric paper	Metric This repo	Avg FPS on GTX 1080Ti	Model
Tusimple	95.87	95.82	306	GoogleDrive/BaiduDrive(code:bghd)
CULane	68.4	69.7	324	GoogleDrive/BaiduDrive(code:w9tw)

For evaluation, run

mkdir tmp
# This a bad example, you should put the temp files outside the project.

python test.py configs/culane.py --test_model path_to_culane_18.pth --test_work_dir ./tmp

python test.py configs/tusimple.py --test_model path_to_tusimple_18.pth --test_work_dir ./tmp

Same as training, multi-gpu evaluation is also supported.

Visualization

We provide a script to visualize the detection results. Run the following commands to visualize on the testing set of CULane and Tusimple.

python demo.py configs/culane.py --test_model path_to_culane_18.pth
# or
python demo.py configs/tusimple.py --test_model path_to_tusimple_18.pth

Since the testing set of Tusimple is not ordered, the visualized video might look bad and we do not recommend doing this.

Speed

To test the runtime, please run

python speed_simple.py  
# this will test the speed with a simple protocol and requires no additional dependencies

python speed_real.py
# this will test the speed with real video or camera input

It will loop 100 times and calculate the average runtime and fps in your environment.
