    針對運動(dòng)員彈跳過(guò)程持續時(shí)間短,彈跳位置相對不固定,彈跳高度測試操作復雜的問(wèn)題,提出一種基于線(xiàn)陣光電成像技術(shù)的運動(dòng)員垂直彈跳高度測試方法;首先構建大視場(chǎng)垂直彈跳高度測試系統,線(xiàn)陣CCD相機進(jìn)行實(shí)時(shí)獲取,得到目標彈跳軌跡圖像;然后對目標彈跳軌跡圖像進(jìn)行圖像分析和處理,高精度提取彈跳特征點(diǎn),從而獲得運動(dòng)員垂直彈跳的運動(dòng)時(shí)間;最后依據運動(dòng)學(xué)公式,實(shí)現運動(dòng)員垂直彈跳高度的準確測試;進(jìn)行多組實(shí)驗并分析實(shí)驗數據,結果表明在1500mm的彈跳測試范圍內,實(shí)驗相對誤差范圍在3%以?xún)龋C明了該方法的可行性。

    Abstract:

    Aiming at the problems of short duration of athletes' jumping process, relatively unstable jumping position and complicated operation of jumping height test, a vertical jumping height test method for athletes based on linear photoelectric imaging technology is proposed. Firstly, a large field of view vertical bounce height test system is constructed, and the linear CCD camera obtains the real-time bounce trajectory image of the target. Then, the image of the target bouncing trajectory is analyzed and processed, and the bouncing feature points are extracted with high precision, so as to obtain the movement time of the athlete's vertical bouncing; Finally, according to the kinematics formula, the accurate test of athletes' vertical bounce height is realized. Several groups of experiments are carried out and the experimental data are analyzed. The results show that the relative error of the experiment is within 3% within the range of 1500mm bounce test, which proves the feasibility of this method.
