摘要:
室内人体感知是智能家居与医疗保健的基础,但RGB相机在私人室内环境中存在隐私问题,而低分辨率热红外相机提供的空间与语义信息有限,大规模室内热红外数据集及实际部署仍较匮乏。本文提出Indoor RGB-T,这是一个用于室内人体感知的大规模配对RGB-热红外数据集,涵盖20个室内房间,包含90576帧80×62热红外图像、87016个时间匹配的RGB-热红外图像对,以及115557个标注的人体边界框。我们建立了基准:针对鲁棒热红外居住者状态检测的平均精度(mAP)为0.75,针对未见过房间的居住者估计准确率为0.847;进一步评估RGB到热红外、热红外到RGB的图像转换,温度平均绝对误差(MAE)为0.654℃,决定系数(R²)为0.923。最后,我们将热红外感知模型部署到商用睡眠监测系统中,对100名参与者的实地测试及约1000台设备的部署验证了其实际可行性。我们还指出了推动未来研究方向的实际挑战,包括环境热干扰、感知范围及多人遮挡,代码、训练模型及部分数据集可在指定URL获取。
英文摘要:
Indoor human perception is the foundation for smart homes and healthcare. However, RGB cameras raise privacy concerns in private indoor environments, while low-resolution thermal cameras provide limited spatial and semantic information. Large-scale indoor thermal datasets and real-world deployments remain limited. Here, we introduce Indoor RGB-T, a large-scale paired RGB--thermal dataset for indoor human perception. The dataset covers 20 indoor rooms and contains 90,576 80x62 thermal frames, 87,016 temporally matched RGB--thermal pairs, and 115,557 annotated human bounding boxes. We establish benchmarks for robust thermal occupant-state detection with 0.75 mAP and occupancy estimation with an accuracy of 0.847 in unseen rooms. We further evaluate RGB-to-thermal and thermal-to-RGB translation, achieving a temperature MAE of 0.654 C and an R2 of 0.923. Finally, we deploy the thermal perception model on a commercial sleep-monitoring system in the real world. Field testing with 100 participants and deployment of approximately 1,000 devices further demonstrate its practical feasibility. We identify practical challenges that motivate future research directions, including environmental thermal interference, sensing range and multi-person occlusion.
