人工智能異常狀況偵測技術 Abnormal Detection Tech @ HKU SAIL
人工智能異常狀況偵測技術,由香港大學電機電子工程系的運動人工智能實驗室研發,運用了人工智能和深度學習分析影像中的不尋常情況,可以有廣泛的應用。 場景應用包括溺水警報,大型活動的安全保障,院舍學童安全保障 及行人動作姿勢分析 溺水警報 當有泳者在游泳池裏溺水,系統可以即時在出事地點附近的警報燈發出警報,救生員可以馬上去救援。此系統曾經榮獲2021年香港資訊及通訊科技獎。 大型活動的安全保障 AI異常狀況偵測技術也應用在大型活動的安全,當參與活動中有異常情況時,系統可以自動檢測和追蹤異常點,讓保安人員可以作出及時應變,保障與會者的安全。 院舍學童安全保障 另外很多地方例如學校院舍都已經安裝了閉路電視保安系統,並有二十四小時錄影設備,這系統亦可以擔當作一個機械巡查員,智能地監察每一個鏡頭的每分每秒,當有異常情況發生時就會記錄下來,向主管報告,以確保學生和院舍院友的安全,一些院舍例如為輕度智障學童提供住宿服務的匡智之家和童樂居正在試用這人工智能技術以提升院舍的服務質素。 院舍學童安全保障及行人動作姿勢分析 此外我們亦獲運輸署的智慧交通基金支持,研究利用人工智能和深度學習技術,利用熱能圖像分析行人的姿勢、動作、速度和異常情況,以提升道路安全。研究亦會探究利用行人動作姿勢,判斷是否長者和殘疾人士,以延長行人閃動「綠色人像燈」時間,方便相關人士橫過馬路及提升道路安全。 人工智能異常狀況偵測技術應用廣泛,不但可以為機構提高安全和服務質素,也可以更善用人手,歡迎聯絡我們查詢。 sail@hku.hk

HKU Smart Swim project - Swimmer Performance Analysis System ENG HD
HKU Smart Swim project - Swimmer Performance Analysis System It deployed the latest artificial intelligence technology for swimmers and coach to use the cameras installed in the swimming pool to record and analysis their performance. Swimmers first record their I D, then different camera could record the jump start, acceleration and swimming actions. The jump parameters such as start angle, distance speed and the angle of insertion into water could be measured and provide objective data for coach and swimmers to evaluate. During swimming, artificial intelligence technology could identify the key points like head, shoulder, arm, hip, leg, foot and calculate the stroke frequency and arm span length. Energy output and efficiency can be determined. Swimmer could go to the kiosk and access the performance data on the touch screen. The system could analyses individual performance from jump start to the end by a series of cameras along the lane so that the coach can point out the issues and give improvement suggestions more effectively. In addition, the system also supports group training analysis. Multiple swimmers can train their leg or arm stroke under the cameras and the system could analyze their performance collectively. This solution makes swimming training more interesting and effective.

HKU AI Drowning Detection System 人工智能溺水偵測系統(Cantonese)
人工智能溺水偵測系統,由香港大學運動人工智能實驗室開發,利用先進的人工智能技術,把安裝在泳池水裡和水面的視頻影像分析,勾劃出人體的骨架,分析游泳者的動作,系統會計算游泳者溺水的概率,當概率高於境界綫時,警報系統會先發出黃色警號,但如果溺水情況持續,就會升級至紅色警號,並在救生台的移動裝置發出警號,顯示遇溺者的位置,讓救生員可以及早拯救遇溺者。這系統可以同時偵測到多位泳手的位置和姿勢,亦可同時配合安裝在天花的鏡頭,從高處監控水面偵測溺水情況,有助減輕救生員的工作量和壓力,加強泳池的安全。這系統可以把原始影像處理後,只利用骨架數據來作分析,這樣可以避免記錄泳手的真面目及保障游泳者的私隱。 人工智能溺水偵測系統可保障生命讓游泳更安全。
