Using an in-cabin DMS camera, the system analyzes the driver's facial video in real time, detects eye open/closed state, calculates blink rate per minute (normal range 15-20 blinks/min), and identifies single-blink closure duration. | 通过车载DMS摄像头实时分析驾驶员面部视频，检测眼部开闭状态，计算每分钟眨眼频率（正常约为15-20次/分钟），并识别闭眼持续时间。当眨眼频率异常降低（如<10次/分钟）或出现单次闭眼超过2秒（微睡眠前兆）时，输出疲劳驾驶预警，联动车内语音提醒或震动座椅，预防因疲劳导致的事故。
