【摘要】：對長跑運(yùn)動員的起跑圖像姿態(tài)的優(yōu)化矯正,能夠有效提高運(yùn)動員跑步效率。對運(yùn)動員起跑姿態(tài)圖像的矯正,需要計(jì)算相同位置像素塊的絕對差分,給出長跑運(yùn)動員起跑姿態(tài)合理性匹配閾值,完成對起跑姿態(tài)優(yōu)化矯正。傳統(tǒng)方法先建立區(qū)域像素點(diǎn)之間的聯(lián)系,生成起跑姿態(tài)圖像的高斯模型,但忽略了給出姿態(tài)合理性匹配閾值,導(dǎo)致姿態(tài)矯正精度偏低。提出基于朗斯基函數(shù)的圖像分析下長跑運(yùn)動員起跑姿態(tài)優(yōu)化校正方法。利用三維圖像分析原理給出運(yùn)動員起跑姿勢的區(qū)域與背景顯露區(qū)域,通過朗斯基矩陣行列式判斷相鄰像素間空間域相關(guān)性,計(jì)算當(dāng)前幀中搜索窗口中心位置的待匹配像素塊與參照幀中相同位置像素塊的絕對差分,給出長跑運(yùn)動員起跑姿態(tài)合理性匹配閾值,完成對長跑運(yùn)動員起跑姿態(tài)優(yōu)化校正。仿真證明,所提方法矯正效果較為明顯,對運(yùn)動員專項(xiàng)技術(shù)動作的形成與發(fā)揮有著積極意義。
[Abstract]:The optimization and correction of the starting image posture of the long distance runners can effectively improve the running efficiency. It is necessary to calculate the absolute difference of the pixel blocks in the same position to correct the starting posture image of the athletes. The reasonable matching threshold of the starting posture of the long distance runners is given to complete the optimization correction of the starting posture. The traditional method firstly establishes the connection between regional pixels and generates Gao Si model of the starting posture image, but neglects to give the matching threshold of attitude rationality, which leads to the low accuracy of attitude correction. This paper presents an image analysis method based on Ransky function to correct the starting posture of long distance runners. Based on the theory of 3D image analysis, the regions of starting position and background exposure of athletes are given, and the spatial correlation between adjacent pixels is judged by Ransky matrix determinant. The absolute difference between the matching pixel block in the current frame searching window center position and the same position pixel block in the reference frame is calculated, the reasonable matching threshold of the starting posture of the long-distance runner is given, and the optimization correction of the starting posture of the long-distance runner is completed. The simulation results show that the correction effect of the proposed method is obvious and has a positive significance to the formation and display of athletes' special technical actions.
