【摘要】：提出了1個(gè)基于Kalman濾波和局部區(qū)域匹配的足球球員檢測(cè)算法。首先利用改進(jìn)的主顏色分割提取場(chǎng)地,使得預(yù)設(shè)參數(shù)個(gè)數(shù)降為1個(gè),增加了算法的適用性;其次對(duì)球員進(jìn)行運(yùn)動(dòng)跟蹤,根據(jù)Kalman濾波器預(yù)測(cè)的位置設(shè)置局部搜索區(qū)域,采用局部構(gòu)圖的方法獲得球員最佳匹配,并在球員遮擋情況下對(duì)不同隊(duì)球員和裁判間的分離采用顏色直方圖匹配和質(zhì)心判定,對(duì)同隊(duì)隊(duì)員遮擋輔助相對(duì)位置及運(yùn)動(dòng)軌跡跟蹤。實(shí)驗(yàn)證明,該算法對(duì)于多目標(biāo)在場(chǎng)景中的遮擋、分離、消失及出現(xiàn)均具有很好的處理效果。
[Abstract]:A soccer player detection algorithm based on Kalman filtering and local area matching is proposed. Firstly, the improved main color segmentation is used to extract the site, which reduces the number of preset parameters to 1, which increases the applicability of the algorithm. Secondly, the players are tracked, the local search area is set according to the position predicted by the Kalman filter, and the best match of players is obtained by the method of local composition. The color histogram matching and centroid decision are used to separate the players and referees under the condition of player occlusion, and the auxiliary relative position and motion track of the same team members are occluded by using the color histogram matching and centroid decision. The experimental results show that the algorithm has a good effect on the occlusion, separation, disappearance and appearance of multi-targets in the scene.
