Abstract:	居家環境為幼兒事故頻發的場所，而幼童通常在家庭和幼兒園環境中度過大部分時間。因此，確保居家安全對於幼童的安全至關重要，而其中跌倒更是最為常見的事故。目前現存的幼兒危險偵測方法主要以穿戴式感測器為主，功能單一且使用不便。此外，現有的深度學習方法在居家環境中的跌倒偵測研究相對較少，仍有許多值得探索的方向。因此，本論文提出一個基於深度學習技術的幼兒危險行為監測系統，旨在即時辨識幼兒的動作並偵測跌倒事故。本系統將幼兒的姿勢分為五個類別：站姿、趴姿、躺姿、坐姿和跌倒。其中跌倒被視為最重要的動作，當系統偵測出跌倒的發生，將快速發出警報或通知給家長或監護人。由於目前未有公開的幼兒動作資料集，故本文蒐集了網路上的真實幼兒影片，共計1006 部影片，包含了居家環境中各種視角的幼兒影片。並以連續影像作為輸入，利用深度學習、影像處理演算法和骨架辨識等技術，能夠識別幼兒的動作，並進一步檢測跌倒事故的發生。本系統在動作辨識方面的accuracy 為89.1%。在跌倒偵測方面的 precision 為76.1%，recall 為81.6%。在執行速度上也能達成即時辨識的效果。這些結果證明本系統能有效監測幼兒的危險行為，對於幼兒護理、安全監控等領域也具有潛在的應用價值。;The home environment is where accidents frequently occur for children, and children typically spend most of their time in the home and kindergarten environment. Therefore, ensuring a safe home is critical to the safety of children, and falls are the most common accident. At present, the existing methods for children’s danger detection are mainly based on wearable sensors, which have a single function and are inconvenient to use. In addition, the existing deep learning methods for fall detection in the home environment are relatively few, and there are still many directions worth exploring. Therefore, this paper proposes a monitoring system for children’s dangerous behaviors based on deep learning technology, which aims to recognize children’s actions and detect falls in real time. The system divides the children’s posture into five categories: standing posture, lying up, lying down, sitting posture and falling posture. Among them, falling is regarded as the most important action. When the system detects the occurrence of a fall, it will quickly send an alarm or notify the parents or guardians. Since there is no publicly available children’s action data set, this article collects real children’s videos on the Internet, a total of 1006 videos, Contains videos for children from various perspectives in the home environment. And with continuous images as input, using technologies such as deep learning, image processing algorithms, and skeleton detection, It can recognize the actions of children and further detect the occurrence of falls. The accuracy of this system in motion recognition is 89.1%. The precision in fall recognition is 76.1%, and the recall is 81.6%. The effect of instant recognition can also be achieved in terms of execution speed. These results prove that the system can effectively monitor children’s dangerous behaviors, and it also has potential application value in fields such as child care and safety monitoring.
