Decoding Pedestrian Crossing Intention from Egocentric Vision via Vision Language Models
TL;DR
Traffic safety prediction lacks effective methods to interpret pedestrian behavior. This study utilizes vision language models (VLMs) to decode pedestrian crossing intentions from egocentric video clips.
✦ Why It Matters
Engineers can leverage VLMs to enhance pedestrian safety systems and improve traffic management solutions.
Key Takeaways
- Explore VLMs for real-time pedestrian intent prediction.
- Consider egocentric video data for traffic safety applications.
- Benchmark different VLM families for optimal performance.
- Integrate findings into traffic management systems for improved safety.
Full Summary
Egocentric vision provides a first-person perspective that can improve traffic safety predictions, yet its application in understanding pedestrian behavior is limited. This research formulates the task of decoding pedestrian crossing intentions as a closed-ended visual question answering (VQA) problem, employing vision language models (VLMs) to analyze short video clips.
Three families of state-of-the-art VLMs were benchmarked to assess their effectiveness in predicting pedestrian intent. The methodology involved training these models on annotated video data to enhance their understanding of context and intent.
Results indicated significant improvements in intent prediction accuracy, demonstrating the potential of VLMs in real-time traffic scenarios. These findings suggest that integrating VLMs into traffic systems could lead to better safety measures for pedestrians.
Overall, this work opens avenues for further research in pedestrian behavior analysis and traffic safety applications.
