摘要:

我们提出了GazeOnce360,一种新颖的端到端模型,用于从单个桌面安装的向上面向鱼眼摄像头进行多人凝视估计。与传统方法依赖于受限视角的前向摄像头不同,我们解决了在向上鱼眼视角下估计360°场景中多个分布人员的3D凝视方向的未探索设置。为了支持该设置的研究,我们引入了MPSGaze360,一个使用Unreal Engine渲染的大规模合成数据集,包含多样化的多人配置,具有精确的3D凝视和眼地标注。我们的模型通过引入旋转卷积和眼地标监督,解决鱼眼图像固有的严重失真和视角变化问题。为了更好地捕捉对凝视估计至关重要的细粒度眼特征,我们提出了一种双分辨率架构,融合全局低分辨率上下文与高分辨率局部眼区。实验结果展示了模型各组件的有效性。本文工作强调了基于鱼眼的360°凝视估计在实际多人场景中的可行性和潜力。项目页面:https://caizhuojiang.github.io/GazeOnce360/.

英文摘要:

We present GazeOnce360, a novel end-to-end model for multi-person gaze estimation from a single tabletop-mounted upward-facing fisheye camera. Unlike conventional approaches that rely on forward-facing cameras in constrained viewpoints, we address the underexplored setting of estimating the 3D gaze direction of multiple people distributed across a 360° scene from an upward fisheye perspective. To support research in this setting, we introduce MPSGaze360, a large-scale synthetic dataset rendered using Unreal Engine, featuring diverse multi-person configurations with accurate 3D gaze and eye landmark annotations. Our model tackles the severe distortion and perspective variation inherent in fisheye imagery by incorporating rotational convolutions and eye landmark supervision. To better capture fine-grained eye features crucial for gaze estimation, we propose a dual-resolution architecture that fuses global low-resolution context with high-resolution local eye regions. Experimental results demonstrate the effectiveness of each component in our model. This work highlights the feasibility and potential of fisheye-based 360° gaze estimation in practical multi-person scenarios. Project page: https://caizhuojiang.github.io/GazeOnce360/.
