摘　　要：篮球投篮过程中会出现打手违规动作姿态,由于打手动作姿态发生时间短、动作姿态发生位置不确定等因素,因此在识别上存在较大难度.提出基于图像检索技术的篮球投篮打手动作姿态识别方法,分析打手动作姿态构成像素区域特征,利用图像检索技术,在有效像素特征区域寻找突破口.预处理投篮动作姿态图像边缘轮廓特征的图像,确定图像有效区域;检索投篮动作姿态图像特征,提取打手动作姿态区域像素特征;通过位置图像识别样本训练,实现对打手动作的姿态识别.测试结果表明,文中方法在识别精度、准确度、响应速度等方面具有一定优势,为图像检索技术在体育领域的应用提供借鉴.In the process of basketball shooting,there will be illegal action posture of the batter.There are fac-tors such as the short time of the occurrence of the batter′s action posture and the uncertainty of the position of the action posture.There is great difficulty in the recognition.In order to solve the above problems,a basketball shooter′s gesture recognition method based on image retrieval technology is proposed.Analyze the characteris-tics of the pixel region formed by the batter′s movement posture,use image retrieval technology to find a break-through in the effective pixel feature region,preprocess the image of the edge contour feature of the shooting posture image,and determine the effective region of the image.Then the image features of shooting posture are retrieved,and the pixel features of the beater′s posture region are extracted;Finally,the position image recogni-tion sample training is used to realize the recognition of the beater′s movement posture.Experimental tests have shown that the proposed method for recognizing the posture of basketball shooters has strong capabilities in improving recognition accuracy,accuracy,and response speed.

关 键 词：篮球投篮 打手动作姿态 姿态识别 图像检索
