Microsoft Kinect感應器是一套結合一般彩色攝影機、紅外線深度攝影機及麥克風陣列的感測裝置,具偵測人體骨架之關節點位置、語音識別等功能。 本研究提出一套基於Microsoft Kinect感應器開發之可即時偵測他人敵意動作並告警的人身安全防護系統,藉由Kinect感應器所回傳之關節位置、被識別之語句資料結合影像辨識及支持向量機(Support Vector Machine,SVM)的輔助,即時判斷環境中來自於人類或類人形物件可能的攻擊動作並提出警告。 A Microsoft Kinect Sensor is a combination of an RGB camera, an infrared camera, and a microphone array. It can detect human skeletons with joint positions. In addition, it also provides voice recognition function. In this thesis, we use the Kinect sensors to construct a personal security system, which can instantly detect the hostile actions of others and alert the user to these dangers.
