This repository contains a moded version of PyTorch YOLOv5 (https://github.com/ultralytics/yolov5). It filters out every detection that is not a person. The detections of persons are then passed to a Deep Sort algorithm (https://github.com/ZQPei/deep_sort_pytorch) which tracks the persons. The reason behind the fact that it just tracks persons is that the deep association metric is trained on a person ONLY datatset.
The implementation is based on two papers:
- Simple Online and Realtime Tracking with a Deep Association Metric https://arxiv.org/abs/1703.07402
- YOLOv4: Optimal Speed and Accuracy of Object Detection https://arxiv.org/pdf/2004.10934.pdf
Python 3.8 or later with all requirements.txt dependencies installed, including torch>=1.6. To install run:
pip install -U -r requirements.txt
All dependencies are included in the associated docker images. Docker requirements are:
nvidia-docker- Nvidia Driver Version >= 440.44
- Clone the repository recursively:
git clone --recurse-submodules https://github.com/mikel-brostrom/Yolov5_DeepSort_Pytorch.git
If you already cloned and forgot to use --recurse-submodules you can run git submodule update --init
- Github block pushes of files larger than 100 MB (https://help.github.com/en/github/managing-large-files/conditions-for-large-files). Hence you need to download two different weights: the ones for yolo and the ones for deep sort
- download the yolov5 weight from the latest realease https://github.com/ultralytics/yolov5/releases. Place the downlaoded
.ptfile underyolov5/weights/ - download the deep sort weights from https://drive.google.com/drive/folders/1xhG0kRH1EX5B9_Iz8gQJb7UNnn_riXi6. Place ckpt.t7 file under
deep_sort/deep/checkpoint/
Tracking can be run on most video formats
