摘要

摘要为了有效提升运动员的训练质量,对运动的三维光学步骤进行了研究,探讨了一种基于改进逆向运动学的三维光学动作幅度跟踪过程。该方法通过针孔摄像机,模型标定摄像机成像平面,定位标记出现在间隔相邻单序列动作幅度的标记点上,然后由摄像机在不同位置和姿态上在同一直线上捕获同一直线的五点透视成像。通过实验评价和与其他类似方法的比较,证明了该匹配方法的准确性和优越性。这一特性可以通过同一相机的左右图像帧来区分。平移运动以10 - 80mm /s的速度改变,旋转运动以10 - 300mm /s的速度调整。在确认过程中,给出了操作目标的旋转、纵向运动和旋转点的空间位置测量、立体视觉运动计算系统的计算变异性,并对方法进行了高度跟踪,为提高运动员的训练质量奠定了基础。仿真实验结果表明,所实现的方法具有较高的搜索精度,为进一步提高运动员训练质量奠定了坚实的平台。

Research on nonlinear tracking and evaluation of sports 3D vision action
Abstract In order to effectively upgrade the training quality of the athlete, the study of the three-dimensional optical steps of sports, a three-dimensional optical action amplitude tracing process based on improved reverse kinematics is discussed. The method passes through a pinhole camera, the model calibrate the camera imaging plane, the positioning mark appears in the marker point in the apart neighboring single-sequence action amplitude and then the five-point perspective imaging of the same line is captured on the same straight line by the camera on different positions and postures. The matching method’s accuracy and superiority are demonstrated through experimental evaluation and compared with other similar measures. This characteristic is distinguished by the left and right image frames of the same camera. The translational movement is altered in 10–80 mm/s and the rotational movement is adjusted in 10–300 mm/s. During the confirmation, the spinning of the operational target, the longitudinal movement and the spatial location of the rotation point Measurement, the calculation variability of the stereoscopic visual moving calculation system, is given, and the method of tracking the method is high, which lay the foundation for the promotion of the training quality of the athlete. The experimental findings from simulation demonstrate that the implemented approach has great searching accuracy, establishing a solid platform for further improving the quality of athletes’ training.

期刊介绍: The Journal of Nonlinear Engineering aims to be a platform for sharing original research results in theoretical, experimental, practical, and applied nonlinear phenomena within engineering. It serves as a forum to exchange ideas and applications of nonlinear problems across various engineering disciplines. Articles are considered for publication if they explore nonlinearities in engineering systems, offering realistic mathematical modeling, utilizing nonlinearity for new designs, stabilizing systems, understanding system behavior through nonlinearity, optimizing systems based on nonlinear interactions, and developing algorithms to harness and leverage nonlinear elements.
