📖 Introduction

This repository is the official PyTorch implementation for OmDet-Turbo, a fast transformer-based open-vocabulary object detection model.

⭐️Highlights

1. OmDet-Turbo is a transformer-based real-time open-vocabulary detector that combines strong OVD capabilities with fast inference speed. This model addresses the challenges of efficient detection in open-vocabulary scenarios while maintaining high detection performance.
2. We introduce the Efficient Fusion Head, a swift multimodal fusion module designed to alleviate the computational burden on the encoder and reduce the time consumption of the head with ROI.
3. OmDet-Turbo-Base model, achieves state-of-the-art zero-shot performance on the ODinW and OVDEval datasets, with AP scores of 30.1 and 26.86, respectively.
4. The inference speed of OmDetTurbo-Base on the COCO val2017 dataset reach 100.2 FPS on an A100 GPU.

🚀 How To Run

Local Inference

1. Download our pretrained model and the CLIP checkpoints.
2. Create a folder named resources, put downloaded models into this folder.
3. Run run_demo.py, the images with predicted results will be saved at ./outputs folder.

Run as a API Server

1. Download our pretrained model and the CLIP checkpoints.
2. Create a folder named resources, put downloaded models into this folder.
3. Run run_wsgi.py, the API server will be started at http://host_ip:8000/inf_predict, check http://host_ip:8000/docs to have a try.

We already added language cache while inferring with run_demo.py. For more details, please open and check run_demo.py scripts.

⚙️ How To Export ONNX Model

1. Replace OmDetV2Turbo in OmDet-Turbo_tiny_SWIN_T.yaml with OmDetV2TurboInfer
2. Run export.py, and the omdet.onnx will be exported.

In the above example, post processing is not included in onnx model , and all input size are fixed. You can add more post processing and change the input size according to your needs.
