【摘要】：对排球发球技术路径视频图像的正确性校正,能够有效提高排球比赛中的得分率,提升比赛水平。对排球发球视频图像的校正,需要首先获取发球动作关节点的最优位置,给出合理性判断阈值,完成对发球技术路径视频图像的校正。传统方法先对发球动作窗口进行预测,确定下一帧窗口质心位置,但忽略了给出发球动作图像正确性判断阈值,导致校正精度偏低。提出基于改进逆向运动学的排球发球动作视频图像正确性校正方法。利用SLIC方法获取排球发球动作区域和背景区域的颜色特征,对候选区域进行超级像素分割,给出像素级的判别结果,对排球发球动作与背景信息进行统计分析,给出排球发球动作位置分布,对发球动作外观模型进行模板匹配,获取发球动作关节点的最优位置,给出排球发球动作图像正确性判断阈值,完成对排球发球动作视频图像正确性校正。仿真证明,所提方法校正精度较高。
[Abstract]:The correct correction of the video image of the volleyball serve path can effectively improve the scoring rate and the level of the volleyball match. In order to correct the video image of volleyball serve, it is necessary to obtain the optimal position of the key node of the serve action, give the reasonable judgment threshold, and complete the correction of the video image of the serve path. The traditional method first predicts the serve action window and determines the position of the center of mass of the next frame, but neglects to give the correct judgment threshold of the serve action image, which leads to the low accuracy of the correction. An improved inverse kinematics based video image correction method for volleyball serve action is proposed. The color features of the volleyball serve area and the background area are obtained by using SLIC method, the candidate regions are segmented with super pixels, the discriminant results at pixel level are given, and the volleyball serve action and background information are statistically analyzed. The location distribution of volleyball serve action is given, the appearance model of serve action is matched by template, the optimal position of the serve action gate node is obtained, and the threshold for judging the correctness of volleyball serve action image is given. Correct the video image of volleyball serve. Simulation results show that the proposed method has high accuracy.
