体育运动中的三维视觉动作幅度跟踪方法仿真

Sports in the 3 d Visual Simulation Movement Range Tracking Method

为了有效地提升运动员的训练质量,需要进行体育运动中的三维视觉动作幅度跟踪方法的研究,但是采用当前方法进行运动动作幅度跟踪时,无法计算出在相邻单目序列动作幅度图像中的标记点,存在三维视觉动作幅度跟踪误差大的问题。为此,提出一种基于改进逆向运动学的体育运动中的三维视觉动作幅度跟踪方法。该方法先根据针孔摄像机模型对摄像机成像平面进行标定,定位标记点出现在相邻单目序列动作幅度中的标记点,在此基础上融合于旋转角方法预测动作幅度在图像中的位置,获取动作幅度的时间序列模型,给出三维视觉动作幅度在寻优区域外部的概率,以此为依据完成对体育运动中的三维视觉动作幅度跟踪。实验仿真证明,所提方法跟踪精度高,为提升运动员的训练质量奠定了结实的基础。

It needs to research the tracking method of 3D visual movement range in the physical exercise in order to improve the training quality of athletes. However, current method cannot work out the marker point in the movement range image of neighbor monocular sequence. Therefore, it leads to big tracking error. This paper proposes a tracking method of 3D visual movement range in the physical exercise based on the modified reverse kinematics. Firstly, the imaging plane of camera is marked according to the pinhole camera model and the mark point is located in the movement range of neighbor monocular sequence. Then, the movement range position in the image is predicated integrated with the rotation angle method, and the time sequence model of movement range is acquired. Moreover, the probability of 3D visual movement range outer the optimizing area is given out. Finally, the 3D visual movement range tracking in the physical exercise is completed. The simulation results show that the proposed method has higher tracking precision. It establishes the firm foundation for improving the training quality of athlete.
