DOTA database training with yolo | 基于DOTA数据集的yolo训练

DOTA database training with yolo | 基于DOTA数据集的yolo训练

clone this repo | 克隆此仓库

git clone xxxx/dota-yolo
cd dota-yolo

download DOTA dataset | 下载数据集

download from | 这里下载 https://captain-whu.github.io/DOTA/dataset.html

then put them as following structure | 然后按如下结构存放

DOTA-yolov3
|
├─dataset
│  ├─train
│  │  ├─images
│  │  └─labelTxt
│  └─val
│      ├─images
│      └─labelTxt

prerequisites | 必要环境

• darknent https://pjreddie.com/darknet/install/
• python3
• opencv-python etc. | opencv-python 等必要包
• Shapely (need geos|需要安装geos)

split | 切割

python3 data_transform/split.py

for more details refer https://github.com/CAPTAIN-WHU/DOTA_devkit

transform label | 转换label

mkdir dataset/trainsplit/labels
mkdir dataset/valsplit/labels
python3 data_transform/YOLO_Transform.py

# check labels
# cd dataset/trainsplit/labels
# awk -F" " '{col[$1]++} END {for (i in col) print i, col[i]}' *.txt

# 

for more details refer https://github.com/ringringyi/DOTA_YOLOv2

generate | 生成 train.txt & val.txt

ls -1d $PWD/dataset/trainsplit/images/* > cfg/train.txt
ls -1d $PWD/dataset/valsplit/images/* > cfg/val.txt

# when too many images
# find "$(pwd)/dataset/trainsplit512/images">cfg/train.txt
# find "$(pwd)/dataset/valsplit512/images">cfg/val.txt

train | 训练

cd cfg
mkdir backup

# yolo-tiny
darknet detector train dota.data dota-yolov3-tiny.cfg 

# more gpus
darknet detector train dota.data dota-yolov3-tiny.cfg -gpus 0,1,2

# resume from unexpected stop
darknet detector train dota.data dota-yolov3-tiny.cfg backup/dota-yolov3-tiny.backup

# or yolov3-416
darknet detector train dota.data dota-yolov3-416.cfg 

config cfg files refer https://medium.com/@manivannan_data/how-to-train-yolov3-to-detect-custom-objects-ccbcafeb13d2

predict | 预测

为了方便运行，这里用 opnencv做检测，要高性能还是用 darknent binding | Here I prepared opencv for easy set up, you can use darknet bindings for better performance

# tiny
python test.py --image test.png --config cfg/dota-yolov3-tiny.cfg --weights cfg/backup/dota-yolov3-tiny_final.weights --classes cfg/dota.names

# or 416
python test.py --image test.png --config cfg/dota-yolov3-416.cfg --weights cfg/backup/dota-yolov3-416_final.weights --classes cfg/dota.names

pretraind params | 预训练的参数
