摘要: 针对短道速滑比赛场景难以获取各运动员运动数据的问题,构建一个多目标跟踪与运动仿真的算法流程。提出一种局部匹配度量方法,处理单视角视频内存在的局部遮挡问题,提升跟踪的稳定性与鲁棒性。基于单应映射和拟合曲线求导的运动仿真方法,估算速度与加速度等运动学参数,实现运动仿真。在短道数据集的仿真实验中,验证了所提方法的有效性与优越性。

Abstract: Aiming at the problem that it is difficult to obtain the motion data of each athlete in the short track speed skating competition, an algorithm flow of multiple object tracking and kinematic simulation is proposed. A local matching metric is proposed to deal with the partial occlusion in monocular video and improve the tracking stability and robustness. The motion simulation method based on homography mapping and derivative of fitted curve is realized to estimate kinematic parameters such as velocity and acceleration. The experiments on Skating Track Multiple ObjectTracking (STMOT) verified the effectiveness and superiority of the proposed methods.

Key words: short track speed skating, multiple object tracking, landmark matching, local matching metric, kinematic simulation
