TPH-YOLOv5

This repo is the implementation of “TPH-YOLOv5: Improved YOLOv5 Based on Transformer Prediction Head for Object Detection on Drone-Captured Scenarios”.
On VisDrone Challenge 2021, TPH-YOLOv5 wins 4th place and achieves well-matched results with 1st place model.

You can get VisDrone-DET2021: The Vision Meets Drone Object Detection Challenge Results for more information.

Install

$ git clone https://github.com/cv516Buaa/tph-yolov5
$ cd tph-yolov5
$ pip install -r requirements.txt

Convert labels

VisDrone2YOLO_lable.py transfer VisDrone annotiations to yolo labels.
You should set the path of VisDrone dataset in VisDrone2YOLO_lable.py first.

$ python VisDrone2YOLO_lable.py

Inference

Datasets : VisDrone
Weights :
- yolov5l-xs-1.pt: | Baidu Drive(pw: vibe). | Google Drive |
- yolov5l-xs-2.pt: | Baidu Drive(pw: vffz). | Google Drive |

val.py runs inference on VisDrone2019-DET-val, using weights trained with TPH-YOLOv5.
(We provide two weights trained by two different models based on YOLOv5l.)

$ python val.py --weights ./weights/yolov5l-xs-1.pt --img 1996 --data ./data/VisDrone.yaml
                                    yolov5l-xs-2.pt
--augment --save-txt  --save-conf --task val --batch-size 8 --verbose --name v5l-xs

Ensemble

If you inference dataset with different models, then you can ensemble the result by weighted boxes fusion using wbf.py.
You should set img path and txt path in wbf.py.

$ python wbf.py

Train

train.py allows you to train new model from strach.

$ python train.py --img 1536 --batch 2 --epochs 80 --data ./data/VisDrone.yaml --weights yolov5l.pt --hy data/hyps/hyp.VisDrone.yaml --cfg models/yolov5l-xs-tr-cbam-spp-bifpn.yaml --name v5l-xs
