【摘要】：对篮球大力扣球动作下上肢轨迹预测问题的研究,能够有效提高篮球比赛中运动员的安全性。对大力扣球动作运动员上肢动作轨迹的预测,需要对上肢动作特征进行提取,对上肢动作动态图像边缘轮廓进行角点检测,完成对上肢动作轨迹的分析。传统方法提取运动员上肢连续动作目标,归一化连续动作下上肢动作轮廓图像,但忽略了对上肢动作图像边缘轮廓的角点检测,完成在大力扣球下上肢动作轨迹的影响。提出基于Harris角点检测的篮球比赛大力扣球下上肢动作特征提取方法。该方法首先映射图像上肢动作区域中像素灰度级的空间分布的属性,采用高斯混合模型标准和归一化运动员大力扣球下上肢动作轮廓,利用Harris角点检测方法对运动员的连续动作图像进行仿射不变闭合区域增强处理,并对运动员上肢动作边缘轮廓进行角点检测,完成对篮球大力扣球下上肢动作特征提取。仿真证明,所提方法特征提取精度高,大幅度的提升了篮球比赛的质量。
[Abstract]:The research on the prediction of the upper limb trajectory under the basketball spike can effectively improve the security of the players in basketball match. It is necessary to extract the upper limb movement feature, detect the edge contour of the upper limb action dynamic image, and complete the analysis of the upper limb movement trajectory. The traditional method is used to extract the athlete's upper limb continuous action target. The contour image of upper limb action is normalized under continuous action, but the corner detection of edge contour of upper limb action image is neglected. This paper presents a method of feature extraction of upper limb movement in basketball match based on Harris corner detection. This method firstly maps the image of upper limb movement region. The attribute of the spatial distribution of a prime gray level. By using Gao Si mixed model standard and normalized athletes' upper limb action contour of strong spike, the Harris corner detection method is used to enhance the affine invariant closed area of the player's continuous action image. At the same time, the corner point detection of the edge contour of the athlete's upper limb action is carried out, and the feature extraction of the upper limb movement under the basketball powerful spike is completed. The simulation results show that the proposed method has high precision of feature extraction. The quality of the basketball match was greatly improved.
