Welcome to the exciting world of multi-object tracking using OC-SORT! This advanced motion-model-based tracker enhances tracking capabilities, especially in crowded environments and when objects exhibit non-linear movements. In this guide, we will delve into how to set up and utilize OC-SORT effectively, along with some troubleshooting tips.

Understanding OC-SORT: An Analogy

Imagine you are the conductor of an orchestra, where each musician represents an object in a scene. Just like a conductor’s role is to ensure that each musician plays in harmony, OC-SORT pulls together various tracking elements for each object to ensure smooth and accurate tracking. The traditional Kalman filter can be likened to an inexperienced conductor who struggles to coordinate the musicians, while OC-SORT is the seasoned conductor who recognizes and addresses each musician’s unique style, resulting in a flawless performance. By integrating different detectors and matching modules, OC-SORT provides robust tracking akin to an orchestra that plays beautifully, even in the chaos of a crowded concert hall.

Getting Started with OC-SORT

• Installation: Refer to the INSTALL.md for the required components.
• Initial Setup: Use the guide in GET_STARTED.md to navigate through the beginning steps.
• Available Models: Check MODEL_ZOO.md for the YOLOX weights that can enhance your tracking.
• Deployment: Consult DEPLOY.md for deployment support through ONNX, TensorRT, and ncnn.

Running a Demo

To run the tracker using a demo video, you can execute the following shell command:

python3 tools/demo_track.py --demo_type video -f exps/example/mot/yolox_dancetrack_test.py -c pretrained/ocsort_dance_model.pth.tar --path videos/dance_demo.mp4 --fp16 --fuse --save_result --out_path demo_out.mp4

This command will process the specified video using the pre-trained OC-SORT model and will save the result as demo_out.mp4.

Performance Benchmark

OC-SORT has shown promising results in various performance metrics across different datasets:

• MOT17: MOTA of 78.0%
• MOT20: MOTA of 75.9%
• KITTI – Cars: MOTA of 90.3%

The inference speed can reach up to 28 FPS with an RTX 2080Ti GPU, making it suitable for real-time applications!

Troubleshooting Tips

If you encounter any issues while using OC-SORT, consider the following troubleshooting steps:

• Check if all required dependencies are installed by revisiting the INSTALL.md.
• Ensure that the correct model files are being used (check MODEL_ZOO.md).
• For issues related to long processing times, verify the compatibility of your hardware and software with OC-SORT’s requirements.
