Integrated In-vehicle Monitoring System Using 3D Human Pose Estimation and Seat Belt Segmentation
This addresses safety monitoring for vehicle occupants, but it is incremental as it combines existing techniques like pose estimation and segmentation for a specific domain.
The paper tackled the problem of monitoring drivers and passengers in vehicles by proposing a system that integrates 3D human pose estimation, seat-belt segmentation, and seat-belt status classification, achieving high performance suitable for real-time application in in-vehicle environments.
Recently, along with interest in autonomous vehicles, the importance of monitoring systems for both drivers and passengers inside vehicles has been increasing. This paper proposes a novel in-vehicle monitoring system the combines 3D pose estimation, seat-belt segmentation, and seat-belt status classification networks. Our system outputs various information necessary for monitoring by accurately considering the data characteristics of the in-vehicle environment. Specifically, the proposed 3D pose estimation directly estimates the absolute coordinates of keypoints for a driver and passengers, and the proposed seat-belt segmentation is implemented by applying a structure based on the feature pyramid. In addition, we propose a classification task to distinguish between normal and abnormal states of wearing a seat belt using results that combine 3D pose estimation with seat-belt segmentation. These tasks can be learned simultaneously and operate in real-time. Our method was evaluated on a private dataset we newly created and annotated. The experimental results show that our method has significantly high performance that can be applied directly to real in-vehicle monitoring systems.
