【摘要】：對(duì)排球發(fā)球技術(shù)路徑視頻圖像的正確性校正,能夠有效提高排球比賽中的得分率,提升比賽水平。對(duì)排球發(fā)球視頻圖像的校正,需要首先獲取發(fā)球動(dòng)作關(guān)節(jié)點(diǎn)的最優(yōu)位置,給出合理性判斷閾值,完成對(duì)發(fā)球技術(shù)路徑視頻圖像的校正。傳統(tǒng)方法先對(duì)發(fā)球動(dòng)作窗口進(jìn)行預(yù)測(cè),確定下一幀窗口質(zhì)心位置,但忽略了給出發(fā)球動(dòng)作圖像正確性判斷閾值,導(dǎo)致校正精度偏低。提出基于改進(jìn)逆向運(yùn)動(dòng)學(xué)的排球發(fā)球動(dòng)作視頻圖像正確性校正方法。利用SLIC方法獲取排球發(fā)球動(dòng)作區(qū)域和背景區(qū)域的顏色特征,對(duì)候選區(qū)域進(jìn)行超級(jí)像素分割,給出像素級(jí)的判別結(jié)果,對(duì)排球發(fā)球動(dòng)作與背景信息進(jìn)行統(tǒng)計(jì)分析,給出排球發(fā)球動(dòng)作位置分布,對(duì)發(fā)球動(dòng)作外觀模型進(jìn)行模板匹配,獲取發(fā)球動(dòng)作關(guān)節(jié)點(diǎn)的最優(yōu)位置,給出排球發(fā)球動(dòng)作圖像正確性判斷閾值,完成對(duì)排球發(fā)球動(dòng)作視頻圖像正確性校正。仿真證明,所提方法校正精度較高。
[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.
