R³Det: Refined Single-Stage Detector with Feature Refinement for Rotating Object

Abstract

R³Det and R³Det++ are based on Focal Loss for Dense Object Detection, and it is completed by YangXue.

Techniques:

• ResNet, MobileNetV2, EfficientNet
• RetinaNet-H, RetinaNet-R
• R³Det: Feature Refinement Module (FRM)
• R³Det++: Instance Level Denoising (InLD)
• IoU-Smooth L1 Loss
• Circular Smooth Label (CSL)
• Anchor Free (one anchor per feature point)
• mmdetection version is released
• Dataset support: DOTA, HRSC2016, ICDAR2015, ICDAR2017 MLT, UCAS-AOD, FDDB, OHD-SJTU
• OHDet: Object Heading Detection

Download Model

Pretrain weights

1、Please download resnet50_v1, resnet101_v1, resnet152_v1, efficientnet, mobilenet_v2 pre-trained models on Imagenet, put it to data/pretrained_weights.
2、(Recommend in this repo) Or you can choose to use a better backbone (resnet_v1d), refer to gluon2TF.

Compile

cd $PATH_ROOT/libs/box_utils/cython_utils
python setup.py build_ext --inplace (or make)

cd $PATH_ROOT/libs/box_utils/
python setup.py build_ext --inplace

Train

1、If you want to train your own data, please note:

(1) Modify parameters (such as CLASS_NUM, DATASET_NAME, VERSION, etc.) in $PATH_ROOT/libs/configs/cfgs.py
(2) Add category information in $PATH_ROOT/libs/label_name_dict/lable_dict.py     
(3) Add data_name to $PATH_ROOT/data/io/read_tfrecord_multi_gpu.py  

2、Make tfrecord
For DOTA dataset:

cd $PATH_ROOT\data\io\DOTA
python data_crop.py

cd $PATH_ROOT/data/io/  
python convert_data_to_tfrecord.py --VOC_dir='/PATH/TO/DOTA/' 
                                   --xml_dir='labeltxt'
                                   --image_dir='images'
                                   --save_name='train' 
                                   --img_format='.png' 
                                   --dataset='DOTA'

3、Multi-gpu train

cd $PATH_ROOT/tools
python multi_gpu_train_r3det.py

Eval

cd $PATH_ROOT/tools
python test_dota_r3det.py --test_dir='/PATH/TO/IMAGES/'  
                          --gpus=0,1,2,3,4,5,6,7          

Tensorboard

cd $PATH_ROOT/output/summary
tensorboard --logdir=.
