+## Introduction
+
+[CLRNet](https://arxiv.org/abs/2203.10350) is a lane detection model. The CLRNet model is designed with line prior for lane detection, line iou loss as well as nms method, fused to extract contextual high-level features of lane line with low-level features, and refined by FPN multi-scale. Finally, the model achieved SOTA performance in lane detection datasets.

+### CLRNet Results on CULane dataset
+
+| backbone       | mF1 | F1@50   |    F1@75    | download | config |
+| :--------------| :------- |  :----: | :------: | :----: |:-----: |
+| ResNet-18         | 54.98 |  79.46  |    62.10   | [model](https://paddledet.bj.bcebos.com/models/clrnet_resnet18_culane.pdparams) | [config](./clrnet_resnet18_culane.yml) |
+
+### Download
+Download [CULane](https://xingangpan.github.io/projects/CULane.html). Then extract them to `dataset/culane`.
+
+For CULane, you should have structure like this:
+```shell
+culane/driver_xx_xxframe    # data folders x6
+culane/laneseg_label_w16    # lane segmentation labels
+culane/list                 # data lists
+```
+If you use Baidu Cloud, make sure that images in `driver_23_30frame_part1.tar.gz` and `driver_23_30frame_part2.tar.gz` are located in one folder `driver_23_30frame` instead of two seperate folders after you decompress them.
+
+Now we have uploaded a small subset of CULane dataset to PaddleDetection for code checking. You can simply run the training script below to download it automatically. If you want to implement the results, you need to download the full dataset at th link for training.
+
+### Training
+- single GPU
+```shell
+python tools/train.py -c configs/clrnet/clr_resnet18_culane.yml
+```
+- multi GPU
+```shell
+export CUDA_VISIBLE_DEVICES=0,1,2,3
+python -m paddle.distributed.launch --gpus 0,1,2,3 tools/train.py -c configs/clrnet/clr_resnet18_culane.yml
+```
+
+### Evaluation
+```shell
+python tools/eval.py -c configs/clrnet/clr_resnet18_culane.yml -o weights=output/clr_resnet18_culane/model_final.pdparams
+```
+
+### Inference
+```shell
+python tools/infer_culane.py -c configs/clrnet/clr_resnet18_culane.yml -o weights=output/clr_resnet18_culane/model_final.pdparams --infer_img=demo/lane00000.jpg
+```
+
+Notice: The inference phase does not support static model graph deploy at present.
