Child Bedtime Soothing (Fear of Dark / Post-Nightmare) | 儿童睡前情绪安抚（怕黑/噩梦后）

Through a fixed camera (with infrared night vision) and microphone in the child's bedroom, the system analyzes pre-sleep and night-time video and audio to detect pre-sleep crying (continuous crying, calling 'Mama'), fear-of-the-dark expressions (curling up, looking around), and nightmare awakenings (sudden sitting up, trembling, screaming). | 通过儿童卧室的固定摄像头（红外夜视）及麦克风，分析儿童睡前及夜间视频，检测睡前哭闹（持续性哭声、呼喊'妈妈'）、怕黑表现（身体蜷缩、四处张望）、噩梦惊醒（突然坐起、颤抖、尖叫）等行为。当检测到上述情绪不安时，自动触发安抚动作：开启小夜灯（柔光）、播放预先录制的妈妈讲故事音频或轻柔摇篮曲。
