PHRM，利用前置摄像头在用户日常使用中捕捉面部视频，通过深度学习估算心率，误差低于10%，并发布大规模数据集与预训练模型。 Google发布被动心率监测系统，精度达标。 利用前置摄像头无感测量，降低用户负担。 公开大规模数据集和预训练模型。 可应用于健康App、远程监测等场景。 需关注隐私和实际使用限制。 Google Research 开发了一种被动心率监测系统（PHRM），利用智能手机前置摄像头在日常使用中（人脸解锁后数秒内）捕捉面部视频，通过深度学习估算心率，平均绝对百分比误差（MAPE）低于10%（对比心电图金标准），满足各肤色人群的行业精度标准。系统将全天心率测量整合为每日静息心率（RHR），平均绝对误差（MAE）低于5 bpm（对比可穿戴设备）。研究同时发布了迄今最大规模的公开智能手机视频数据集及预训练模型PHRM-mini，合格研究人员可申请访问。 这是什么信号 Google Research 发布了被动心率监测系统 PHRM，利用智能手机前置摄像头进行无接触心率监测，并公开了大规模数据集和基础模型。这不是单纯的技术新闻，而是一个在健康监测领域实现低成本、规模化部署的信号，可能改变传统医疗级心率监测的获取方式。 为什么重要 传统心率监测需要专用硬件或主动配合，PHRM 通过日常人脸解锁行为即可被动测量，极大降低了用户负担。其误差低于行业标准，且数据集涵盖多肤色人群，具备泛化能力。公开的数据集和预训练模型将推动更…","access_level":"public","access_label":"公开","access_mode":"full","is_preview":false,"canonical_url":"https://opc.beizhux.com/content/1105/google-research-phrm","html_url":"https://opc.beizhux.com/content/1105/google-research-phrm","json_url":"https://opc.beizhux.com/content/1105/google-research-phrm.json","published_at":"2026-06-05T04:25:29","updated_at":"2026-10-04T19:39:18","category":{"slug":"hotspots","name":"全球热点解读"},"source":{"site":"research.google","author":"Google
