## 简介
PP-YOLOE-R是一个高效的单阶段Anchor-free旋转框检测模型。基于PP-YOLOE, PP-YOLOE-R以极少的参数量和计算量为代价，引入了一系列有用的设计来提升检测精度。在DOTA 1.0数据集上，PP-YOLOE-R-l和PP-YOLOE-R-x在单尺度训练和测试的情况下分别达到了78.14和78.27 mAP，这超越了几乎所有的旋转框检测模型。通过多尺度训练和测试，PP-YOLOE-R-l和PP-YOLOE-R-x的检测精度进一步提升至80.02和80.73 mAP。在这种情况下，PP-YOLOE-R-x超越了所有的anchor-free方法并且和最先进的anchor-based的两阶段模型精度几乎相当。此外，PP-YOLOE-R-s和PP-YOLOE-R-m通过多尺度训练和测试可以达到79.42和79.71 mAP。考虑到这两个模型的参数量和计算量，其性能也非常卓越。在保持高精度的同时，PP-YOLOE-R避免使用特殊的算子，例如Deformable Convolution或Rotated RoI Align，以使其能轻松地部署在多种多样的硬件上。在1024x1024的输入分辨率下，PP-YOLOE-R-s/m/l/x在RTX 2080 Ti上使用TensorRT FP16分别能达到69.8/55.1/48.3/37.1 FPS，在Tesla V100上分别能达到114.5/86.8/69.7/50.7 FPS。更多细节可以参考我们的技术报告。

PP-YOLOE-R相较于PP-YOLOE做了以下几点改动：
- Rotated Task Alignment Learning
- 解耦的角度预测头
- 使用DFL进行角度预测
- 可学习的门控单元
- [ProbIoU损失函数](https://arxiv.org/abs/2106.06072)

**注意:**
- 如果**GPU卡数**或者**batch size**发生了改变，你需要按照公式 **lr<sub>new</sub> = lr<sub>default</sub> * (batch_size<sub>new</sub> * GPU_number<sub>new</sub>) / (batch_size<sub>default</sub> * GPU_number<sub>default</sub>)** 调整学习率。
- 模型库中的模型默认使用单尺度训练单尺度测试。如果数据增广一栏标明MS，意味着使用多尺度训练和多尺度测试。如果数据增广一栏标明RR，意味着使用RandomRotate数据增广进行训练。
- CRN表示在PP-YOLOE中提出的CSPRepResNet
- 速度测试使用TensorRT 8.2.3在DOTA测试集中测试2000张图片计算平均值得到。参考速度测试以复现[速度测试](#速度测试)
## 使用说明
参考[数据准备](../README.md#数据准备)准备数据。
### 训练
GPU单卡训练
``` bash
CUDA_VISIBLE_DEVICES=0 python tools/train.py -c configs/rotate/ppyoloe_r/ppyoloe_r_crn_l_3x_dota.yml
```
GPU多卡训练
``` bash
CUDA_VISIBLE_DEVICES=0,1,2,3 python -m paddle.distributed.launch --gpus 0,1,2,3 tools/train.py -c configs/rotate/ppyoloe_r/ppyoloe_r_crn_l_3x_dota.yml
```
### 预测
执行以下命令预测单张图片，图片预测结果会默认保存在`output`文件夹下面
``` bash
python tools/infer.py -c configs/rotate/ppyoloe_r/ppyoloe_r_crn_l_3x_dota.yml -o weights=https://paddledet.bj.bcebos.com/models/ppyoloe_r_crn_l_3x_dota.pdparams --infer_img=demo/P0861__1.0__1154___824.png --draw_threshold=0.5
```
### DOTA数据集评估
参考[DOTA Task](https://captain-whu.github.io/DOTA/tasks.html), 评估DOTA数据集需要生成一个包含所有检测结果的zip文件，每一类的检测结果储存在一个txt文件中，txt文件中每行格式为：`image_name score x1 y1 x2 y2 x3 y3 x4 y4`。将生成的zip文件提交到[DOTA Evaluation](https://captain-whu.github.io/DOTA/evaluation.html)的Task1进行评估。你可以执行以下命令得到test数据集的预测结果：
``` bash
python tools/infer.py -c configs/rotate/ppyoloe_r/ppyoloe_r_crn_l_3x_dota.yml -o weights=https://paddledet.bj.bcebos.com/models/ppyoloe_r_crn_l_3x_dota.pdparams --infer_dir=/path/to/test/images --output_dir=output_ppyoloe_r --visualize=False --save_results=True
```
将预测结果处理成官网评估所需要的格式：
``` bash
python configs/rotate/tools/generate_result.py --pred_txt_dir=output_ppyoloe_r/ --output_dir=submit/ --data_type=dota10
zip -r submit.zip submit
```
### 速度测试
速度测试需要确保**TensorRT版本大于8.2, PaddlePaddle版本大于2.4.0rc0**。使用Paddle Inference且使用TensorRT进行测速，执行以下命令：
``` bash
# 导出模型
python tools/export_model.py -c configs/rotate/ppyoloe_r/ppyoloe_r_crn_l_3x_dota.yml -o weights=https://paddledet.bj.bcebos.com/models/ppyoloe_r_crn_l_3x_dota.pdparams trt=True
# 速度测试
CUDA_VISIBLE_DEVICES=0 python configs/rotate/tools/inference_benchmark.py --model_dir output_inference/ppyoloe_r_crn_l_3x_dota/ --image_dir /path/to/dota/test/dir --run_mode trt_fp16
```
## 预测部署
**使用Paddle Inference但不使用TensorRT**进行部署，执行以下命令：
``` bash
# 导出模型
python tools/export_model.py -c configs/rotate/ppyoloe_r/ppyoloe_r_crn_l_3x_dota.yml -o weights=https://paddledet.bj.bcebos.com/models/ppyoloe_r_crn_l_3x_dota.pdparams
# 预测图片
python deploy/python/infer.py --image_file demo/P0072__1.0__0___0.png --model_dir=output_inference/ppyoloe_r_crn_l_3x_dota --run_mode=paddle --device=gpu
```
**使用Paddle Inference且使用TensorRT**进行部署，执行以下命令：
```
# 导出模型
python tools/export_model.py -c configs/rotate/ppyoloe_r/ppyoloe_r_crn_l_3x_dota.yml -o weights=https://paddledet.bj.bcebos.com/models/ppyoloe_r_crn_l_3x_dota.pdparams trt=True
# 预测图片
python deploy/python/infer.py --image_file demo/P0072__1.0__0___0.png --model_dir=output_inference/ppyoloe_r_crn_l_3x_dota --run_mode=trt_fp16 --device=gpu
```
**注意：**
- 使用Paddle-TRT使用确保PaddlePaddle版本大于2.4.0rc且TensorRT版本大于8.2.

## Introduction
PP-YOLOE-R is an efficient anchor-free rotated object detector. Based on PP-YOLOE, PP-YOLOE-R introduces a bag of useful tricks to improve detection precision at the expense of marginal parameters and computations.PP-YOLOE-R-l and PP-YOLOE-R-x achieve 78.14 and 78.27 mAP respectively on DOTA 1.0 dataset with single-scale training and testing, which outperform almost all other rotated object detectors. With multi-scale training and testing, the detection precision of PP-YOLOE-R-l and PP-YOLOE-R-x is further improved to 80.02 and 80.73 mAP. In this case, PP-YOLOE-R-x surpasses all anchor-free methods and demonstrates competitive performance to state-of-the-art anchor-based two-stage model. Moreover, PP-YOLOE-R-s and PP-YOLOE-R-m can achieve 79.42 and 79.71 mAP with multi-scale training and testing, which is an excellent result considering the parameters and GLOPS of these two models. While maintaining high precision, PP-YOLOE-R avoids using special operators, such as Deformable Convolution or Rotated RoI Align, to be deployed friendly on various hardware. At the input resolution of 1024$\times$1024, PP-YOLOE-R-s/m/l/x can reach 69.8/55.1/48.3/37.1 FPS on RTX 2080 Ti and 114.5/86.8/69.7/50.7 FPS on Tesla V100 GPU with TensorRT and FP16-precision. For more details, please refer to our technical report.

**Notes:**
- if **GPU number** or **mini-batch size** is changed, **learning rate** should be adjusted according to the formula **lr<sub>new</sub> = lr<sub>default</sub> * (batch_size<sub>new</sub> * GPU_number<sub>new</sub>) / (batch_size<sub>default</sub> * GPU_number<sub>default</sub>)**.
- Models in model zoo is trained and tested with single scale by default. If `MS` is indicated in the data augmentation column, it means that multi-scale training and multi-scale testing are used. If `RR` is indicated in the data augmentation column, it means that RandomRotate data augmentation is used for training.
- CRN denotes CSPRepResNet proposed in PP-YOLOE
- Speed ​​is calculated and averaged by testing 2000 images on the DOTA test dataset. Refer to [Speed testing](#Speed-testing) to reproduce the results.
## Getting Start
Refer to [Data-Preparation](../README_en.md#Data-Preparation) to prepare data.
### Training
Single GPU Training
``` bash
CUDA_VISIBLE_DEVICES=0 python tools/train.py -c configs/rotate/ppyoloe_r/ppyoloe_r_crn_l_3x_dota.yml
```
Multiple GPUs Training
``` bash
CUDA_VISIBLE_DEVICES=0,1,2,3 python -m paddle.distributed.launch --gpus 0,1,2,3 tools/train.py -c configs/rotate/ppyoloe_r/ppyoloe_r_crn_l_3x_dota.yml
```
### Inference
Run the follow command to infer single image, the result of inference will be saved in `output` directory by default.
``` bash
python tools/infer.py -c configs/rotate/ppyoloe_r/ppyoloe_r_crn_l_3x_dota.yml -o weights=https://paddledet.bj.bcebos.com/models/ppyoloe_r_crn_l_3x_dota.pdparams --infer_img=demo/P0861__1.0__1154___824.png --draw_threshold=0.5
```
### Evaluation on DOTA Dataset
Refering to [DOTA Task](https://captain-whu.github.io/DOTA/tasks.html), You need to submit a zip file containing results for all test images for evaluation. The detection results of each category are stored in a txt file, each line of which is in the following format
`image_id score x1 y1 x2 y2 x3 y3 x4 y4`. To evaluate, you should submit the generated zip file to the Task1 of [DOTA Evaluation](https://captain-whu.github.io/DOTA/evaluation.html). You can run the following command to get the inference results of test dataset:
``` bash
python tools/infer.py -c configs/rotate/ppyoloe_r/ppyoloe_r_crn_l_3x_dota.yml -o weights=https://paddledet.bj.bcebos.com/models/ppyoloe_r_crn_l_3x_dota.pdparams --infer_dir=/path/to/test/images --output_dir=output_ppyoloe_r --visualize=False --save_results=True
```
Process the prediction results into the format required for the official website evaluation:
``` bash
python configs/rotate/tools/generate_result.py --pred_txt_dir=output_ppyoloe_r/ --output_dir=submit/ --data_type=dota10
zip -r submit.zip submit
```
### Speed testing

r"""This code is based on
https://github.com/fcjian/TOOD/blob/master/mmdet/core/bbox/assigners/task_aligned_assigner.py
The assignment is done in following steps
1. compute alignment metric between all bbox (bbox of all pyramid levels) and gt
2. select top-k bbox as candidates for each gt
3. limit the positive sample's center in gt (because the anchor-free detector
only can predict positive distance)
4. if an anchor box is assigned to multiple gts, the one with the
highest iou will be selected.
Args:
pred_scores (Tensor, float32): predicted class probability, shape(B, L, C)
pred_bboxes (Tensor, float32): predicted bounding boxes, shape(B, L, 5)
anchor_points (Tensor, float32): pre-defined anchors, shape(1, L, 2), "cxcy" format
num_anchors_list (List): num of anchors in each level, shape(L)
gt_labels (Tensor, int64|int32): Label of gt_bboxes, shape(B, n, 1)
gt_bboxes (Tensor, float32): Ground truth bboxes, shape(B, n, 5)
pad_gt_mask (Tensor, float32): 1 means bbox, 0 means no bbox, shape(B, n, 1)
bg_index (int): background index
gt_scores (Tensor|None, float32) Score of gt_bboxes, shape(B, n, 1)
Returns:
