摘要
文中介绍了一个利用VFWSDK和数字图像技术的辅助射击训练分析系统 ,该系统能够更科学的发现、纠正射击运动员不正确的动作和分析击发的最佳时机。该系统实时采集射击运动员在训练过程中的连续瞄准点变换图像 ,基于多线程技术 ,采用投影法并辅助于运动估计和隔行扫描技术的方法 ,可以准确、快速、并行地确定每帧图像的瞄准点位置。拟合连续多帧图像的瞄准位置可再现枪实际瞄准轨迹和运动员的瞄准过程。事实证明此系统能达到实时化要求 ,并具有很强的鲁棒性 。
To reveal and correct the fault of the athletes aim motion more scientifically, and discover the best shoot time, a computer aided shoot analysis system is introduced in this paper, which employs VFW SDK and digital image process technical. It collects the athletes aim image stream in real time. Based on the multithreads technology, the projection algorithm and interlacing scanning technique, the aim point in every image can be calculated with fast speed and high accuracy. Then the detail of pistol movement and the athletes aim process are illustrated clearly when all the aim points are drawn sequentially. It has been testified that this system can work in real time and be robust, at the same time it avoids inadequate storage problem.
