• August 30, 2022: We've released the inference code / trained model and published web demo, just enjoy it !

• August 24, 2022: We've released the tech report for YOLOPv2. This work is still in progress and code/models are coming soon. Please stay tuned! ☕️

Introduction

:grin:We present an excellent multi-task network based on YOLOP:blue_heart:,which is called YOLOPv2: Better, Faster, Stronger for Panoptic driving Perception. The advantages of YOLOPv2 can be summaried as below:

• Better:clap:: we proposed the end-to-end perception network which possess better feature extraction backbone, better bag-of-freebies were developed for dealing with the training process.
• Faster:airplane:: we employed more efficient ELAN structures to achieve reasonable memory allocation for our model.
• Stronger:muscle:: the proposed model has stable network design and has powerful robustness for adapting to various scenarios .

Results

We used the BDD100K as our datasets,and experiments are run on NVIDIA TESLA V100.

Web Demo

• Integrated into Huggingface Spaces 🤗 using Gradio. Try out the Web Demo !

Visualization

model : trained on the BDD100k dataset and test on T3CAIC camera.
