摘 要： 提出了一種新的關節點權值自適應的姿勢相似度計算方法，選用Kinect體感設備采集姿勢信息，獲取人體骨架關節點數據.為適應不同人體體型，根據骨架長度對關節點數據進行修正.另外，針對不同的人體姿勢，提出自適應的關節點權值定義方法.實驗結果表明：所提出的姿勢相似度計算方法準確度高并且結果穩定.

關鍵詞： 關節點權值; 源數據修正; Kinect; 權值自適應; 姿勢相似度

Abstract： A novel posture similarity calculation method using selfadaptive joint weight was proposed in this paper.Kinect was selected to collect posture information，using which the human skeleton joint data was acquired.In order to accommodate various body shapes，the data of joints was modified according to the length of skeletons.In addition，the definition of selfadaptive joint weight was proposed in terms of various human postures.The experimental results showed that the proposed posture similarity calculation method achieved high accuracy and stable results.

Key words： joint weight; source data modification; Kinect; weight selfadaptation; posture similarity

本文提出了一種新的自適應關節點權值的姿勢相似度計算方法，該方法以模板姿勢關節點為基礎，對待測試姿勢的關節點進行調整，有效解決了不同體型、位置之間的姿勢預處理問題.以模板姿勢的骨架長度為參考，給每個關節點增加一個權值，計算姿勢相似度.實驗結果表明：所提出的姿勢相似度計算方法效果較好.
