Thermal Relative Fever Screening (Multi-Person Gathering) | 家庭多人聚集时体温相对异常检测

Using a fixed thermal-imaging camera installed in public areas (e.g., living room, dining room), the system automatically analyzes each person's skin-surface temperature (usually forehead or facial region) when multiple people gather, and computes the difference between an individual's temperature and the average temperature of others in the scene. | 通过安装于公共区域（如客厅、餐厅）的固定热成像摄像头，在多人聚集时自动分析每个人的体表温度（通常为额头或面部区域），计算个体温度与场景内其他人平均温度的差值。当某个人温度显著高于周边人群（差值超过预设阈值，如1.5℃）时，输出'体温相对异常'提醒，建议使用额温枪复测。
