摘要 

目前运动员跑步训练强度仿真结果只是单一的画面,导致运动员跑步训练强度仿真结果,可视性低、仿真时间长,与运动员跑步运动实际结果不一致,为此提出利用反映帧间图像界定运动员跑步训练强度仿真。采用统计学测量方法获取运动员生理参数,并计算匹配因子,将运动员的生理参数与仿真人的生理参数进行匹配;在仿真平台确定仿真人关节转动、旋转角度、跑步步长、步调、步速与运动员一致,校准仿真人运动姿态;将校准后的运动姿态数据代入仿真平台,利用反映帧间图像形成连续的运动员跑步训练虚拟动画,分析运动员跑步训练,对运动员跑步训练强度进行界定。实验结果显示,在同一实验参数下,检测仿真结果与人体真实跑步运动模型的一致度,得出所提方法可以准确仿真运动员跑步运动姿态,可视性高、仿真时间短,与运动员跑步运动实际结果一致,仿真效果好,能够为监督运动员跑步训练过程提供一定帮助。

Abstract: 

At present, the simulation results of athletes' running training intensity are only a single screen, which leads to the low visibility and long simulation time of athletes' running training intensity, which are inconsistent with the actual results of athletes' running. For this reason, it is proposed to use the images reflected between frames to define the athletes' running training intensity. simulation. Use statistical measurement methods to obtain athletes’ physiological parameters, and calculate matching factors to match athletes’ physiological parameters with those of the simulated human; determine the simulated human’s joint rotation, rotation angle, running step length, pace, pace and speed on the simulation platform Athletes are consistent, calibrate the motion posture of the simulated person; substitute the calibrated motion posture data into the simulation platform, and use the images reflected between frames to form a continuous virtual animation of athlete running training, analyze the athlete's running training, and define the athlete's running training intensity. The experimental results show that under the same experimental parameters, the consistency between the simulation results and the real running motion model of the human body is detected. It is concluded that the proposed method can accurately simulate the athlete's running posture, with high visibility and short simulation time, which is consistent with the actual running movement of the athlete. The results are consistent, the simulation effect is good, and it can provide some help for supervising the athletes' running training process.
