Using an in-cabin DMS camera, the system analyzes the driver's facial video in real time, detecting skin color variation (flush index, derived from red-channel ratio in RGB or skin-color models) and sweat-droplet / reflective area (via image texture and reflection features). When the flush index rises significantly (possibly indicating elevated blood pressure, fever or strong emotion) or the sweating area exceeds the threshold (possibly indicating heat stress, hypoglycemia or cardiac issues), it outputs a health-risk reminder and suggests the driver to rest or seek medical help. The skill aims to help drivers stay aware of their physical state and avoid accidents caused by sudden illness. Application scenarios: passenger cars, commercial vehicles, ride-hailing fleets, freight fleets. Real-time monitoring; when flushing or heavy sweating is detected, it voice-prompts 'please pay attention to your physical state, rest is recommended' or pushes the event to the fleet-management platform. Skill features: sudden illness of drivers (e.g., heart attack, heatstroke, hypoglycemia) often leads to vehicle loss of control and major accidents. AI real-time monitoring of facial flushing and abnormal sweating provides an early reminder for drivers to take a break or seek help, reducing accident risk. Can serve as a value-add feature on DMS systems, especially suitable for commercial and ride-hailing fleets. | 通过车载DMS摄像头实时分析驾驶员面部视频，检测面部肤色变化（潮红指数，通过RGB色空间中的红色分量比例或肤色模型）以及汗珠/反光面积（通过图像纹理和反射特征）。当潮红指数显著升高（可能提示血压升高、发热或情绪激动）或出汗区域面积超过阈值（可能提示热应激、低血糖或心脏问题）时，输出健康风险提醒，建议驾驶员停车休息或就医。该技能旨在辅助驾驶员关注自身健康，避免因突发疾病引发事故。应用场景：乘用车、商用车、网约车、货运车队。系统实时监测，当检测到面部潮红或大量出汗时，通过语音提示'请注意身体状态，建议休息'或推送至车队管理平台。技能特点：驾驶员突发疾病（如心梗、中暑、低血糖）往往会导致车辆失控，引发重大事故。通过AI实时监测面部潮红和出汗异常，可早期提醒驾驶员关注自身状态，采取休息或求助措施，降低事故风险。该技能可作为DMS系统的增值功能，提升车辆主动安全水平，尤其适合营运车辆和网约车平台。
