RayFusion: Ray Fusion Enhanced Collaborative Visual Perception
- 基于合作车辆的光线占用信息进行融合，减少深度歧义
- 在nuScenes数据集上相较最优基线3D检测性能提升5.2%
- 适合研究自动驾驶多车协同感知与视觉3D检测的团队
近年来，协同视觉感知方法因能解决传感器局限问题而在自动驾驶领域受到广泛关注。然而，缺乏显式深度信息常导致基于摄像头的感知系统（如3D目标检测）难以生成准确预测。为缓解深度估计中的模糊性，我们提出RayFusion，一种基于光线的协同视觉感知融合方法。利用协作节点提供的光线占用信息，RayFusion减少了沿相机射线的冗余和误检，提升了纯摄像头协同感知系统的检测性能。大量实验表明，该方法持续优于现有最先进模型，在nuScenes数据集上实现显著性能提升。代码已公开于https://github.com/wangsh0111/RayFusion。
原文摘要 · Abstract (English)
Collaborative visual perception methods have gained widespread attention in the autonomous driving community in recent years due to their ability to address sensor limitation problems. However, the absence of explicit depth information often makes it difficult for camera-based perception systems, e.g., 3D object detection, to generate accurate predictions. To alleviate the ambiguity in depth estimation, we propose RayFusion, a ray-based fusion method for collaborative visual perception. Using ray occupancy information from collaborators, RayFusion reduces redundancy and false positive predictions along camera rays, enhancing the detection performance of purely camera-based collaborative perception systems. Comprehensive experiments show that our method consistently outperforms existing state-of-the-art models, substantially advancing the performance of collaborative visual perception. The code is available at https://github.com/wangsh0111/RayFusion.
